The climate of Gujarat involves diverse conditions.[1] The plains of Gujarat are very hot and humid in summer and cold and dry in winter. Summer is milder in the hilly regions and the coast. The average daytime temperature during winter is around 29 °C (84 °F) and in nights is around 12 °C (54 °F) with 100 percent sunny days and clear nights. During summers, the daytime temperature is around 49 °C (120 °F) and at night no lower than 30 °C (86 °F). The monsoon season lasts from June to September. Most of Gujarat receives scant rainfall. Southern Gujarat and the hilly regions receive heavy rainfall during the monsoons with high humidity which makes the air feel hotter. There is relief when the monsoon season starts (around mid June). The day temperatures are lowered to around 35 °C (95 °F) but humidity is very high and nights are around 27 °C (81 °F). Most of the rainfall occurs in this season, and the rain can cause severe Floods. The sun is often occluded during the monsoon season. Though mostly dry, it is desertic in the north-west, and wet in the southern districts due to a heavy monsoon season.
