On November 24, 2025, Rajasthan experienced intense cold wave conditions, with Fatehpur (Sikar district) recording the lowest temperature of 5.8°C, followed by Lunkaransar (Bikaner) at 6.6°C and Churu at 7.8°C. The India Meteorological Department (IMD) issued Yellow Alert cold wave warnings for districts including Ajmer, Jhunjhunu, Kota, Sikar, and Tonk. The unusually early and sharp drop in temperatures — described as record-breaking for November — was attributed to cold north-westerly winds from the Himalayan region, clear skies facilitating rapid radiative cooling at night, and the absence of western disturbances. Cold waves in Rajasthan are caused by continental polar air masses moving southward from Central Asia through the Thar Desert corridor. Rajasthan's geography — largely arid and semi-arid — makes it prone to extreme temperature swings: scorching summers above 48°C and severe winters below 0°C in some areas. The cold wave affects agricultural operations (rabi crop sowing — mustard, wheat, gram), livestock health, and the vulnerable homeless and migratory worker populations. Rajasthan's Disaster Management Authority issues advisories for kisan (farmer) protection and maintains shelters (rain baseras) in urban areas during cold wave periods.
