The '''climate of [[Delhi]]''' is a monsoon-influenced [[humid subtropical]] ([[Köppen climate classification]] ''Cwa'') 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]], [[Tokyo]] and [[Brisbane]] in that the city features [[dust storms]] (something more commonly seen in a [[desert climate]]), has relatively dry winters and has a prolonged spell of very hot weather. Summers start in early April and peak in May, with average temperatures near 32 °C (90 °F), although occasional heat waves can result in highs close to 45 °C (114 °F) on some days. The monsoon starts in late June and lasts until mid-September, with about 797.3 mm (31.5 inches)<ref name=ecosurv1>{{cite web

The average temperatures are around 29 °C (85 °F), although they can vary from around 25 °C (78 °F) on rainy days to 32 °C (90 °F) during dry spells. The monsoons recede in late September, and the post-monsoon season continues till late October, with average temperatures sliding from 29 °C (85 °F) to 21 °C (71 °F).
Winter starts in November and peaks in January, with average temperatures around 12–13 °C (54–55 °F). Although winters are generally mild, Delhi's proximity to the [[Himalaya]]s results in cold waves. Delhi is notorious for its heavy fogs during the winter season. In December, reduced visibility leads to disruption of road, air and rail traffic.<ref name=Fog>{{cite news

{{Delhi weatherbox}}
Delhi recorded the coldest day on 2nd Jan 2013 in last 44years with max temperatures 9.8 and 9.7degC at Safdarjung and Palam respectively
With the persistent thick fog coverage over Delhi during last three days, the max temperatures were hovering between 13-15deg C on 31 Dec 2012 to 1st Jan 2013 with min temp 4-5deg C. On 2nd Jan 2013, the city continued to experience thick fog coverage but with longer duation till late noon 1130IST. In the late noon and afternoon of 2nd Jan, 2013, there were strong cold winds of 10-20km per hour at surface from north to northwest from Himalayan region. The winds facilitated lifting of the dense fog coverage from surface, but the fog remained as lifted fog/lower stratus and kept covering the skies and there were hardly any sun light today. This is the 3rd day, in succession when Delhi did not get much sun shine required for day temp to rise. Though the winds advected from colder areas and mountains of north lifted the fog, it also pulled down the day temp to a record lowest of 9-10deg C around the city.Thus the main reason for coldest day on 2nd Jan was the remnant of fog as lifted fog and cold air advection over Delhi.
The earlier records of very low day max temp in Jan( <13deg C) at both airports of Delhi since 1969 are enclosed in the table.
Forecast-With changing wind pattern during next 48hours, day temp is likely to increase by about 2-3 degC on 3 Jan with min temp close to 4degC. The dense fog conditions will again start tonight and continue for tomorrow morning but duration and intensity will gradually reduced during next 3-days.
