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^oC (90^oF), although occasional heat waves can result in highs close to 45^oC (114^oF) on some days. The monsoon starts in late June and lasts until mid-September, with about 797.3&nbsp;mm (31.5&nbsp;inches)<ref name=ecosurv1>{{cite web | url = http://www.imd.gov.in/section/climate/newdelhi1.htm | title = Climatological Table | accessdate = 2009-05-13 | publisher = Indian Meteorological Department }}</ref> of rain. The average temperatures are around 29^oC (85^oF), although they can vary from around 25^oC (78^oF) on rainy days to 32^oC (90^oF) during dry spells. The monsoons recede in late September, and the post-monsoon season continues till late October, with average temperatures sliding from 29^oC (85^oF) to 21^oC (71^oF). Winter starts in November and peaks in January, with average temperatures around 12-13^oC (54-55^oF). Although winters are generally mild, Delhi's proximity to the [[Himalaya]]s results in cold waves that regularly dip temperatures below freezing {{Citation needed|date=July 2010}}. Delhi is notorious for its heavy fog during the winter season. In December, reduced visibility leads to disruption of road, air and rail traffic<ref name=Fog>{{cite news | publisher=The Hindu| url=http://www.hindu.com/2005/01/07/stories/2005010719480300.htm| title=Fog continues to disrupt flights, trains| date=2006-01-07| accessdate=2006-05-16 }}</ref>. They end in early February, and are followed by a short spring till the onset of the summer. Extreme temperatures have ranged from &minus;0.6&nbsp;[[Celsius|°C]] (30.9&nbsp;[[Fahrenheit|°F]]) to 47&nbsp;°C (116.6&nbsp;°F).<ref name=coldDelhi>{{cite news| publisher=Hindustan Times| url= http://www.hindustantimes.com/news/181_1593200,000600010001.htm| title=At 0.2 degrees Celsius, Delhi gets its coldest day| date=2006-01-08| accessdate=2006-04-29}}</ref> ==Notes== {{Reflist}} [[Category:Delhi]] [[Category:Geography of Delhi]] gggggggggggggggggggggggggggggggggggg'
