Climate - Islamabad (Pakistan)

The climate of Islamabad is subtropical, with mild, quite rainy winters and hot, very rainy summers due to the Indian monsoon.
The city is the capital of Pakistan and is located in the north of the country, on the Potohar plateau, at an altitude of 500 meters (1,650 feet) and 33 degrees north latitude. Nearby is the city of Rawalpindi, which is effectively merged with Islamabad.
Just north of the city are the Margalla Hills, whose highest peak is Tilla Charouni, 1,604 meters (5,262 feet) high. Sometimes, on these hills in winter it can snow above 1,000 meters (3,300 feet). To the north-east is the Pir Panjal mountain range.
The proximity of the mountains makes the climate more rainy than in the other cities of Pakistan, as regards to the disturbances that arrive in winter and spring, but especially in July and August, when the rains brought by the monsoon are very abundant.
In winter, from December to February (but sometimes also in November and March), nights are often cold. On the coldest nights of the year, the temperature can drop to the freezing point or a little below.
Also, from November to February, fog can form at night and in the early morning. Generally, the fog dissolves during the day, however, in these situations, especially from mid-December to mid-January, it can sometimes be cold even during the day, and there may be periods in which the maximum remain around 8/10 °C (46/50 °F).
On the other hand, from mid-April to early July, before the monsoon, it is very hot, though less than in the cities of Pakistan located at sea level. In the hottest periods, the temperature can reach 45/46 °C (113/115 °F).
