Rajasthan Temperature GK
This lesson covers Rajasthan's maximum and minimum temperature pattern from an exam point of view. Temperature questions usually connect continentality, desert surface, thermal range, isotherms, loo, dust devils, cold waves, frost, crops and climate adaptation.
5.1 General Thermal Pattern
Rajasthan has a continental climate, so temperature variation is strong.
| Season | Average Maximum | Average Minimum | Exam Memory |
|---|---|---|---|
| Summer, March-June | 40-45°C | 24-28°C | May-June peak; western desert may cross 48-50°C |
| Monsoon, July-September | 32-36°C | 21-25°C | Temperature falls, humidity creates discomfort |
| Autumn, October-November | 30-34°C | 15-18°C | October heat / Kartik heat memory |
| Winter, December-February | 20-25°C | 4-10°C | January coldest; night temperature can touch 0°C or below |
5.2 Thermal Extremes And Records
| Point | Exam Memory |
|---|---|
| Hottest place | Phalodi; 51.0°C recorded on 19 May 2016 |
| Traditionally hottest district headquarters | Churu |
| Long high-temperature memory | Sri Ganganagar |
| Coldest high-altitude place | Mount Abu, Sirohi |
| Coldest plain centre | Fatehpur, Sikar |
| Strong annual thermal range | Churu |
Mount Abu becomes cold because of altitude. Fatehpur is remembered as a cold plain centre. Churu is important because it can be very hot in summer and very cold in winter.
5.3 Temperature Range
Daily Temperature Range
The daily range is highest in the western desert, especially around Jaisalmer-Barmer. Sandy soil heats quickly in daytime and cools quickly at night. Clear sky and low humidity increase this effect.
Annual Temperature Range
The annual range is strongest around Churu because of continentality, dry surface and extreme summer-winter contrast.
5.4 Isotherms
| Month | Isotherm Memory |
|---|---|
| January 8°C | Northern edge: Sri Ganganagar, Hanumangarh |
| January 10°C | Bikaner, Sikar, Alwar belt |
| January 12°C | Jodhpur, Nagaur, Jaipur, Dausa belt |
| January 16°C | Southern belt: Udaipur, Dungarpur, Banswara, Jhalawar |
| July 30°C | South and south-east Rajasthan |
| July 32°C | Eastern plains |
| July 36°C+ | Western Thar, Jaisalmer, Phalodi, Bikaner |
5.5 Temperature-Related Seasonal Phenomena
| Phenomenon | Cause / Time | Impact |
|---|---|---|
| Loo | Hot dry winds in May-June | Heatstroke, dehydration, shelterbelt importance |
| Baboolya | Small cyclonic dust whirl due to intense local heating | Dusty winds and local instability |
| Cold wave | North-western cold winds after Himalayan snowfall | 4-6°C fall; Churu, Sikar, Ganganagar affected |
| Frost | Night temperature 0°C or below | Mustard, gram, tomato and chilli can be damaged |
5.6 Exam One-Liners
- Phalodi is remembered for the highest official temperature record of 51.0°C.
- Mount Abu is the coldest high-altitude place in Rajasthan.
- Fatehpur in Sikar is remembered as the coldest plain centre.
- Churu has a strong annual temperature range.
- Daily temperature range increases from east to west.
- Loo is a hot dry wind of May-June.
- Baboolya is a dust-devil type local whirl.
- Frost damages rabi crops when temperature falls to 0°C or below.
- October heat is also remembered as Kartik heat or Kwar ki dhoop.
- Sandy desert surface is the main reason for high daily temperature range.
