Delhi Weather

Climate & Weather, Delhi

The climate of Delhi is an overlap between monsoon-influenced humid subtropical with high variation between summer and winter temperatures and precipitation. Delhi's version of a humid subtropical climate is markedly different from many other humid subtropical cities such as Sao Paulo, New Orleans and Brisbane in that the city features dust storms, has relatively dry short winters and has a prolonged spell of very hot weather, due to its semi-arid climate.

Summer is certainly not the best time to visit Delhi. It starts in early April and peaks in May, with average temperatures near 32 DC although occasional heat waves can result in highs close to 45 DC on some days and therefore higher apparent temperature. The monsoon starts in late June and lasts until mid-September, with about 797.3 mm of rain. The average temperatures are around 29 DC, although they can vary from around 25 DC on rainy days to 32 DC during dry spells. The monsoons recede in late September, and the post-monsoon season continues till late October, with average temperatures sliding from 29 DC to 21 DC.

Winter starts in late November or early December and peaks in January, with average temperatures around 12–13 DC.Although winters are generally mild, Delhi's proximity to the Himalayas results in cold waves leading to lower apparent temperature due to wind chill. Delhi is notorious for its heavy fogs during the winter season. In December, reduced visibility leads to disruption of road, air and rail traffic. They end in early February, and are followed by a short spring until the onset of the summer.

Extreme temperatures have ranged from −2.2 DC to 48.4 DC.
