Sindh lies in a [[tropical]] to [[subtropical]] region; it is hot in the summer and mild to warm in winter. Temperatures frequently rise above {{convert|46|°C|°F|abbr=on|lk=on}} between May and August, and the minimum average temperature of {{convert|2|°C|°F|abbr=on}} occurs during December and January in the northern and higher elevated regions. The annual rainfall averages about seven inches, falling mainly during July and August. The southwest monsoon wind begins in mid-February and continues until the end of September, whereas the cool northerly wind blows during the winter months from October to January.

Sindh lies between the two [[monsoon]]s—the southwest monsoon from the Indian Ocean and the northeast or retreating monsoon, deflected towards it by the [[Himalayas|Himalayan mountains]]—and escapes the influence of both. The region's scarcity of rainfall is compensated by the inundation of the Indus twice a year, caused by the spring and summer melting of Himalayan snow and by rainfall in the monsoon season.

Sindh is divided into three climatic regions: Siro (the upper region, centred on [[Jacobabad]]), Wicholo (the middle region, centred on [[Hyderabad, Sindh|Hyderabad]]), and Lar (the lower region, centred on [[Karachi]]). The [[thermal equator]] passes through upper Sindh, where the air is generally very dry. Central Sindh's temperatures are generally lower than those of upper Sindh but higher than those of lower Sindh. Dry hot days and cool nights are typical during the summer. Central Sindh's maximum temperature typically reaches {{convert|43|-|44|C|F}}. Lower Sindh has a damper and humid maritime climate affected by the southwestern winds in summer and northeastern winds in winter, with lower [[rainfall]] than Central Sindh. Lower Sindh's maximum temperature reaches about {{convert|35|-|38|C|F}}. In the Kirthar range at {{convert|1800|m|ft|abbr=on}} and higher at [[Gorakh Hill]] and other peaks in [[Dadu District]], temperatures near freezing have been recorded and brief snowfall is received in the winters.
