Kerala’s climate remained warm in 2025, marking the 13th warmest year on record. The average land surface air temperature hit 25.82°C, which is 0.22°C above the long-period average (1991–2020). This followed 2024’s scorching year, the warmest since 1901, when temperatures were 0.99°C above normal. Unlike the persistent heat of 2024, 2025 had varied seasonal temperatures. Winter was notably warm, with a +0.63°C anomaly, ranking as the fifth warmest winter on record. Other seasons stayed close to typical levels. Annual maximum and minimum temperatures were also above normal by 0.13°C and 0.31°C, ranking 14th and 10th warmest respectively since 1901. The report from the Institute for Climate Change Studies notes a steady warming trend. Eight of the ten warmest years occurred in the last decade (2016–2025), making it the warmest decade ever. Kerala’s annual mean temperature has grown by about 1.15°C per 100 years. Maximum temperatures rose faster than minimum temperatures, increasing by 1.77°C per 100 years compared to 0.53°C for minimums. Since the late 1980s, maximum temperatures exceeded minimums, causing greater daily temperature swings. Rainfall totaled 2,925.7 mm in 2025, 1.2% above the long-term average (1971–2020). However, monsoon rains dropped sharply, with a 13% shortfall in the southwest monsoon and 21% in the northeast monsoon. This drop matches a century-long decline. Kerala’s coastal waters stayed warmer than usual too. The mean sea surface temperature was 0.47°C above normal in the north and 0.42°C in the south. Though cooler than 2024’s record warmth, ocean warming continues long-term. These trends underline ongoing climate changes affecting Kerala’s environment and weather patterns.
