Rajasthan experienced a severe cold spell in late November 2025, with the Meteorological Centre Jaipur (IMD) tracking sharply falling night temperatures across several districts, but IMD Jaipur's impact-based forecast for November 30 did not show cold-wave warnings for Ajmer, Jhunjhunu, Kota, Sikar, or Tonk on that date. Mount Abu's minimum temperature dropped to 0°C in November for the first time in 15 years, while Fatehpur recorded the state's lowest temperature at 2.9°C. Sikar emerged as the coldest district with minimum temperatures between 5–7°C — breaking previous November records. Overall, 11 cities in Rajasthan recorded temperatures below 10°C. The unusually intense cold wave was driven by powerful northwesterly winds originating from Himalayan snowfall regions combined with a weakened upper-air cyclonic circulation favouring dry and cold conditions. Twelve districts across Rajasthan were recording sub-10°C night temperatures weeks earlier than the normal winter onset. The cold wave posed health risks, particularly for the elderly, children, and homeless populations, and the Rajasthan government activated warming centres (rein baseras) in urban areas. Farmers were also advised to take precautionary measures to protect winter crops (rabi crops) like wheat, mustard, gram, and vegetables from frost damage. The IMD forecast that cold conditions would persist into early December.
