Tamil Nadu Climate |
||
Tamil Nadu has a tropical climate with little difference in temperature in summer and winter. April and May are the hottest months with the mercury often soaring above the 40ºC mark. Coastal regions get uncomfortably warm and humid during these months but the nights are usually cool, thanks to the sea breeze that sets in during the afternoon. Summer temperatures are quite equable in the foothills of the Ghats. Hill stations are pleasant and the maximum temperature rarely rises above the mid twenties. A mild winter falls between November and February when the climate is pleasantly cool. Minimum temperatures in the plains rarely dip below 20º C, while in the hills the mercury may drop to 5º C or below. The north-east monsoon brings rain in spurts between October and December. The average annual rainfall, ranges between 25 and 75 inches (635 and 1,905 mm) a year. Highest precipitation occurs in the Nilgiris and other hill areas with the least in the Ramanathapuram and Tirunelveli districts. |
