#GK-JK #climate #geography #lecture2
About this lecture Second lecture of the GK of Jammu & Kashmir series by Tawqeer Sir (EACET Classes). Topic: Climate of Jammu & Kashmir. Recommended prerequisite: "Climate of India" video (same channel) — many base concepts (latitude zones, monsoon, western disturbances) are assumed known.
Exam Strategy Note
- Relevant for both JKSSB and JKPSC.
- JKPSC: expect statement-based questions (2–4 statements, identify correct/incorrect) → focus on understanding trends, not just memorizing numbers.
- JKSSB: expect direct/basic factual questions (e.g., "hottest month in Kashmir Valley?").
- Don't try to memorize every number — focus on the trend (which season/month is hottest, coldest, wettest, driest) — that's what's actually tested.
1. Climate vs Weather — Core Concepts
Definitions
- Weather = meteorological conditions (temperature, humidity, pressure, wind, precipitation) at a given moment/short period.
- Climate = the average weather pattern of a region over a long period (typically last 30 years).
Factors Affecting Climate of a Region
| Factor | Effect |
|---|---|
| Latitude | Distance from equator → determines base temperature (tropical=hot, polar=cold) |
| Altitude | Higher altitude → cooler climate (even at same latitude) |
| Wind patterns | e.g., Monsoon winds → determine where/when it rains |
| Proximity to water bodies & ocean currents | Coastal areas moderated by sea; currents create deserts/rain zones (e.g., cold currents → coastal deserts) |
Why Jammu ≠ Kashmir ≠ Ladakh in climate despite similar region
- Ladakh & Kashmir are at similar altitude, but Ladakh gets far less rain (rain-shadow effect).
- Jammu is more humid & hotter (lower altitude, plains) than Kashmir Valley.
- Altitude is the single biggest reason J&K's three regions differ so much despite being close together.
2. Latitudinal Zones (Recap)
| Latitude | Line/Zone |
|---|---|
| 0° | Equator |
| 23°30′ N | Tropic of Cancer |
| 23°30′ S | Tropic of Capricorn |
| 66° N | Arctic Circle |
| 66° S | Antarctic Circle |
- Region between the 2 Tropics → Tropical / Torrid Zone (hottest — sun rays perpendicular)
- Region between Tropic and Arctic/Antarctic Circle → Temperate Zone
- Region beyond Arctic/Antarctic Circle to poles → Polar Zone (coldest — sun rays always slanting)
- Subtropical Zone = 5° above and 5° below each Tropic
Why temperature varies by latitude Sun's rays are perpendicular over the equator (twice/year) and each Tropic (once/year each). Perpendicular rays = more concentrated heat = hotter. Near poles, rays are always slanting = spread out = colder.
Where does J&K fall?
- India (& J&K) lies mostly in the Subtropical Zone → hence India's climate = Subtropical Monsoon type
- But altitude modifies this within J&K — mountainous Kashmir behaves more like a Temperate zone despite being in a subtropical latitude.
3. Overview — Three Climatic Divisions of J&K (incl. Ladakh)
| Region | Broad Climate Type | Analogy |
|---|---|---|
| Jammu | Subtropical Monsoon type | Similar to plains of North India |
| Kashmir | Continental / Temperate type | Similar to temperate latitude regions (like Europe) |
| Ladakh | Arctic Cold Desert type | Similar to Polar/Arctic regions |
Why Kashmir isn't subtropical despite subtropical latitude Because of high altitude, Kashmir's climate resembles the temperate latitudes rather than the subtropical latitude it geographically sits in. Same logic applies more extremely to Ladakh (polar-like due to extreme altitude).
4. 🟠 CLIMATE OF JAMMU (Subtropical Monsoon Type)
Region Covered
Jammu plains, Kishtwar, Doda, Poonch, Rajouri — broadly classified as subtropical (though some variation exists, e.g. hilly parts).
Why "Subtropical Monsoon"?
- Subtropical → because of its latitudinal location
- Monsoon → because rainfall is caused by monsoon winds
Seasons in Jammu — Only 3 Distinct Seasons
| Season | Duration |
|---|---|
| Winter | November – February |
| Summer | March – June |
| Rainy (Monsoon) | June – October |
No distinct Spring in Jammu Unlike Kashmir, Jammu does not have a clearly separate spring season — it's brief and merges into summer.
❄️ Winter Season (Nov–Feb)
Key Facts
- Starts when high pressure builds over the Ganga-Sutlej plains (Punjab) → winds reverse direction → temperature drops
- Coldest month: January ⭐ (important for JKSSB)
- Mean average temp in Jan: ~13°C (night ~3°C, day up to ~20°C)
- Humidity: ~68%
Winter Phenomena
| Phenomenon | Description |
|---|---|
| Mist / Haze | Reduced visibility due to moisture in cold air |
| Fog | Denser than mist — occurs at night in Jammu (also seen in Punjab/Haryana) |
| Frost | Freezing of dew on grass/leaves when temp near 0°C; damages Rabi crops — mustard, rapeseed, wheat, sugarcane, vegetables, chillies |
| Western Disturbance Rain | Winter rain caused by temperate cyclones from the Mediterranean Sea (via Europe), bring moisture → rain in Jammu, snow in Kashmir; beneficial for Rabi crops |
| Hailstorms | Occur in winter in Jammu (NOT in Kashmir winter — Kashmir gets hail in spring/April instead); damages Rabi crops |
Winter Rainfall Pattern (Important Trend)
- No rain in Nov–Dec (monsoon already withdrawn)
- Rain returns in Jan–Feb–Mar due to Western Disturbances
- Total winter rainfall ≈ 13 cm
☀️ Summer Season (Mar–Jun)
Key Facts
- Temperature rises sharply from March (mean ~18°C) onward
- Hottest month: June ⭐ — mean max temp reaches ~43°C
- Humidity is low in Apr–Jun (before monsoon); rises to ~70% once monsoon arrives (Jul–Sep)
Summer Local Winds
| Wind | Description |
|---|---|
| Loo | Hot, dry winds blowing in May–June; occur due to dry, parched ground; cause discomfort, no rain |
| Dadu | Cool wind descending from the Shivalik hills at night; provides relief from summer heat (Jammu is on southern slope of Shivalik) |
| Dust storms | Occur due to extreme dryness; sometimes bring brief drizzle/relief |
- Rainfall in summer is low: ~1.1 cm (Apr–mid-June, before monsoon arrives)
🌧️ Rainy Season / Monsoon (Jun–Oct)
Key Facts
- Monsoon arrives ~mid-June, continues till September, with occasional "monsoon breaks" (rainless gaps of ~4 days)
- Wettest months: July & August ⭐ (July = 41 cm, August = 35 cm)
- July is THE wettest month overall in Jammu
- ~70–75% of total annual rainfall occurs in July–August combined
- Humidity rises to ~85%; temp still stays around 35°C — described as very "cruel"/uncomfortable weather (high heat + high humidity)
5. 🔵 CLIMATE OF KASHMIR (Continental / Temperate Type)
Why Kashmir's climate differs so much from India's Pir Panjal Range blocks the monsoon winds from crossing into the Kashmir Valley (unlike the lower Shivaliks, which monsoon winds can cross easily). This is the key reason Kashmir's climate is distinct from mainland India/Jammu.
Seasons in Kashmir — 4 Distinct Seasons
| Season | Duration |
|---|---|
| Winter | November – February |
| Spring | March – mid-May |
| Summer | May – September |
| Autumn | September – October (2 months) |
❄️ Winter Season (Nov–Feb)
Key Facts
- Long duration (~4 months), much colder than Jammu
- Coldest month: January ⭐ (same as Jammu & Ladakh)
- Mean minimum temp in January ≈ -5°C (remember the trend, not exact decimal)
- Snowfall (Dec–Feb): ~120 cm total, of which ~40% (≈50 cm) falls in January alone
- The mean maximum and mean minimum temperatures in November read about 14°C and 1.5°C, dropping down to 8°C and −1.4°C in December.
🎿 Chillai Kalan & Related Periods (Important — Asked in Exams!)
| Local Term | Duration | Meaning |
|---|---|---|
| Chillai Kalan | 21 December – 30 January (40 days) | Harshest, coldest period of the year; temp mostly below 0°C |
| Chillai Khurd | 31 January – 19 February (20 days) | Moderately cold period following Chillai Kalan |
| Chillai Bachha | 20 February – 1/2 March (~10 days) | Final, mildest cold spell |
Common Exam Confusion
- Chillai Kalan = 40 days (main harsh winter)
- Chillai Khurd = 20 days
- Chillai Bachha = 10 days All three together make up the coldest winter stretch in the Valley.
Traditional Winter Items (Local Culture)
| Term | Meaning |
|---|---|
| Pheran | Long traditional coat/cloak worn in winter |
| Kangri | Earthen fire-pot (filled with embers) carried under the Pheran for warmth |
| Bukhari | Indigenous room heater used to heat small rooms |
| Zalun | Firewood/fuel wood stored (traditionally in autumn) for use during winter |
- Agricultural activity is completely suspended in winter due to extreme cold + snow.
- Winter rainfall/snowfall also caused by Western Disturbances (same as Jammu, but causes snow here).
- More rain/snow occurs near the mountains (e.g., Anantnag, Gulmarg) than in the central valley floor.
🌸 Spring Season — "Sonth" (March – mid-May)
Key Facts
- Local Kashmiri name: Sonth
- Temperature rises gradually; snow starts melting
- March receives the MAXIMUM rainfall in Kashmir ⭐ (~12.1 cm) — due to Western Disturbances
- Mean max temp: March ~14°C → April ~20°C → May ~25°C
- 30–40% of Kashmir's total annual rainfall occurs in spring
- Hailstorms occur in April–May (unlike Jammu, where hail occurs in winter) — can severely damage apple crops (e.g., Kulgam hailstorm, May 5 — mentioned as a real example)
- Valley is in full bloom — apple, almond blossoms
- Agricultural activity resumes (suspended since winter)
☀️ Summer Season (May – September)
Key Facts
- Hottest month: July ⭐ (NOT June, unlike Jammu!) — mean max temp ~27°C
- Temperature range: up to ~30°C
- Rainfall is LOW here — less than 25% of annual rainfall occurs in summer
- Reason: Pir Panjal blocks monsoon winds from reaching the Valley
Jammu vs Kashmir — Hottest Month Comparison
- Jammu → June (43°C)
- Kashmir → July (27°C) This is a frequently asked comparison question.
🍂 Autumn Season — "Harud" (September – October)
Key Facts
- Transitional season between summer and winter — 2 months
- Least disturbed weather = clearest skies, least rainfall
- Least rainfall of the year occurs here (~2.8–3.3 cm in Sep/Oct)
- Harvest season — rice, saffron, apple harvested
- Firewood collection for winter (Jaloon) traditionally begins
- Popular tourist season due to pleasant, clear weather
- Mean temp ~25°C
🗓️ Local Kashmiri Seasons — 6 Seasons (Traditional/Experiential, not scientific)
📅 Local Kashmiri Seasons — 6 Seasons
(Traditional/Experiential, not scientific)
| Local Name | English Season | Duration |
|---|---|---|
| Sonth | Spring | Mid-March – Mid-May |
| Grishma | Summer | Mid-May – Mid-July |
| Wuharat / Varsha | Rainy | Mid-July – Mid-September |
| Harud | Autumn | Mid-September – Mid-November |
| Wandah | Winter | Mid-November – Mid-January |
| Shishur | Severe Winter (Chillai Kalan) | Mid-January – Mid-March |
6. 🟢 CLIMATE OF LADAKH (Arctic Cold Desert Type)
Key Facts
- Climate type: Arctic + Desert (cold, arid)
- Very cold in winter, arid (very little rainfall) — hence called a "Cold Desert"
- Reason for aridity: Ladakh lies in the RAIN SHADOW of the Himalayas (Greater Himalayas block moisture-laden monsoon winds)
- Among the least rainfall areas in India (alongside Jaisalmer, Rajasthan)
Temperature Trends
| Detail | Value |
|---|---|
| Hottest month | March ⭐ (unique — unlike Jammu-June or Kashmir-July!) — max temp up to 25.3°C |
| Mean max temp in July | ~25°C |
| Coldest month | January (same as Jammu & Kashmir) — min temp ~-14.4°C |
| Dras temperature (winter) | Can go down to -30°C to -40°C — among coldest inhabited places |
| Freezing nights | For 9 months (September–May), night temperatures remain below freezing point |
Important & Unique Fact Ladakh's hottest month is MARCH — this is a commonly tested, counter-intuitive fact (most regions peak in June/July).
⚠️ Likely wrong — Ladakh's hottest month is JULY, not March (verified Aug 2026)
Standard climate data for Leh shows the warmest month is July (mean max ≈ 25 °C; the coldest is January). March in Leh is still cold (mean max ≈ 8–9 °C). Your own note is even self-contradictory — it says "March 25.3 °C" and "mean max in July ~25 °C". This "March = hottest" line is a repeated coaching claim but conflicts with actual meteorological data — cross-check your source before treating it as a fact. (Coldest = January is correct.)
Why "Arctic Desert"?
- Arctic → because winters resemble polar-cold regions (like Siberia, Greenland: -20 to -30°C)
- Desert → because rainfall is extremely low (arid conditions)
7. 🧭 Köppen Climate Classification
About Köppen Köppen was a geographer who classified world climates into groups based on temperature & precipitation patterns.
Main Groups
| Code | Climate Type |
|---|---|
| A | Tropical |
| B | Arid (Desert) |
| C | Temperate |
| D | Cold / Continental (high altitude, mountainous) |
| E | Polar |
Common Sub-type Codes
| Code | Meaning |
|---|---|
| f | No dry season (rain year-round) |
| m | Monsoon |
| w | Dry winter |
| s | Dry summer |
| a | Hot summer |
| b | Warm summer |
| h | Hot (desert) |
Köppen Codes for India & J&K — Must Remember!
| Region | Köppen Code | Breakdown |
|---|---|---|
| India (overall) | Am | A = Tropical, m = Monsoon |
| Brazil (example) | Af | A = Tropical, f = Rainforest (no dry season) |
| Jammu | Cwa | C = Temperate, w = Dry winter, a = Hot summer |
| Kashmir | Dfb | D = Cold/Continental, f = No dry season, b = Warm summer |
| Ladakh | Dwd | D = Cold, w = Dry winter, d = Extremely cold winter |
Quick Logic Recap
- Jammu = Cwa → Temperate-ish (subtropical), dry winter, hot summer
- Kashmir = Dfb → Cold/continental, rains all year (no dry season), warm (not hot) summer
- Ladakh = Dwd → Cold, dry winter, extremely severe cold
Micro-variations Pir Panjal region shows a slightly different (Mediterranean-like/warm) sub-type at the micro level — but for exam purposes, remember the 3 main codes above.
🎯 PYQ — Climate concepts were tested (not J&K-specific)
None of the 7 papers had a J&K-climate question, but these exact concepts from this lecture appeared — worth knowing cold:
- Weather vs Climate → Website-Operator Q31 (climate = long-term average).
- Köppen "Af" = Tropical rainforest → Junior-Assistant Q51.
- Land has lower specific heat than water (extremes over land) → Laboratory-Attendant Q70. For JKSSB, expect direct factual climate questions (hottest/coldest month); for JKPSC, statement-based.
8. 🌧️ Rainfall Distribution Across J&K
Overall Average
- J&K average annual rainfall: ~100–113 cm
- Rank by rainfall (highest → lowest): Jammu > Kashmir > Ladakh
- Reason: Jammu gets monsoon rain, which neither Kashmir nor Ladakh fully receives (blocked by Pir Panjal & Himalayas respectively)
- Biggest snowfall period (Valley): January & February, with January highest
Region-wise Rainfall Details
| Region | Annual Rainfall | Peak Rain Month(s) | Key District/Note |
|---|---|---|---|
| Jammu | ~130 cm (highest) | July (monsoon) | Reasi district receives the most rainfall (SW monsoon hits plains before Pir Panjal blocks it) |
| Kashmir | ~70–80 cm | March (Western Disturbance) | Rain also in Jan–Apr; low in May–June; slight rise Jul–Aug; low Sep-Oct-Nov-Dec |
| Ladakh | <35 cm (driest region of J&K, some areas <10 cm e.g. Leh) | — | Comparable to Thar Desert (Rajasthan) rainfall levels |
Why Reasi (Jammu) gets the most rain It lies in the southwestern plains/outer plains area, directly in the path of the Southwest Monsoon, before the winds are blocked by the Pir Panjal/Shivalik ranges.
🔑 Quick Revision Pointers / Short Reminders
Rapid Recall Checklist
General Concepts
- Climate = long-term weather average (~30 yrs) | Factors: latitude, altitude, wind patterns, water bodies/currents
- J&K lies in subtropical latitude, but altitude makes Kashmir & Ladakh behave like temperate/polar zones
Three Climate Zones
| Region | Climate Type | Köppen Code |
|---|---|---|
| Jammu | Subtropical Monsoon | Cwa |
| Kashmir | Continental/Temperate | Dfb |
| Ladakh | Arctic Cold Desert | Dwd |
Coldest Month — SAME everywhere:
January is the coldest month in Jammu, Kashmir, AND Ladakh ⭐⭐⭐
Hottest Month — DIFFERENT in each region (High-yield comparison!):
| Region | Hottest Month | Peak Temp |
|---|---|---|
| Jammu | June | ~43°C |
| Kashmir | July | ~27°C |
| Ladakh | March ⚠️ (unusual!) | ~25.3°C |
Seasons Count
- Jammu → 3 seasons (Winter, Summer, Rainy) — no distinct spring
- Kashmir → 4 seasons (Winter, Spring, Summer, Autumn) — scientifically; 6 local seasons traditionally
6 Local Kashmiri Seasons (2 months each): Sonth (Spring) → Grishma (Summer) → Wuharat (Rainy) → Harud (Autumn) → Wandah (Winter) → Shishur (Severe Winter)
Chillai Periods (Kashmir Winter) — must memorize exact durations:
- Chillai Kalan: 21 Dec – 30 Jan (40 days) — harshest
- Chillai Khurd: 31 Jan – 19 Feb (20 days)
- Chillai Bachha: 20 Feb – ~2 Mar (10 days)
Winter Traditional Items (Kashmir): Pheran (coat), Kangri (fire-pot), Bukhari (room heater), Jaloon (firewood)
Local Winds (Jammu Summer):
- Loo = hot, dry wind (May–June)
- Dadu = cool night wind from Shivaliks (relief)
Rainfall Causes:
- Jammu: Monsoon (Jun–Oct, esp. July & Aug = wettest, ~70-75% of annual rain)
- Kashmir & Jammu Winter Rain: Western Disturbances (Mediterranean-origin temperate cyclones) — causes rain in Jammu, snow in Kashmir
- Kashmir: Max rain in March (Western Disturbance) — NOT monsoon (blocked by Pir Panjal)
- Ladakh: Rain-shadow region → least rainfall in India (with Jaisalmer)
Rainfall Ranking: Jammu (~130cm) > Kashmir (~70-80cm) > Ladakh (<35cm, some areas <10cm)
- Highest rainfall district: Reasi (Jammu division)
Hailstorms:
- Jammu: occurs in winter
- Kashmir: occurs in spring (April–May) — damages apple crop
Kashmir Autumn (Harud): Least disturbed weather, least rainfall of the year, harvest season (rice, saffron, apple), peak tourist season
Ladakh Extra Facts:
- Rain-shadow region (blocked by Himalayas)
- 9 months (Sep–May): night temp below freezing
- Dras: can reach -30 to -40°C
- Coldest inhabited-climate comparisons: Siberia, Greenland
