The land of Pakistan is typically dry and hot all through the year, other than brief rain spells during the monsoons and a small amount of rain during the extremely short winter season. The climate of Pakistan can be classified into 4 distinct seasons:
Winter Season (December to Mid-march)
This is the most favorable season in the country’s plains, where the daytime is slightly cold and the temperature hovers around 70 ° F or 21 ° C all through the country. However, nights are a little colder. The maximum temperature on the hill stations is about 10 ° C, and it also snows here. This is typically a dry season, and the weather is cool, pleasant and sunny other than a small amount of run that results from western disturbance.
Pre-Monsoon Season (Mid March to June)
The plains of Pakistan get sufficiently hot by mid-March, with the temperature being about 32.2 ° C. The rains of the wintertime diminish gradually by this time, and the air gets extremely dry. There is a significant rise in temperature, and it is usually over 38 ° C. By the first week of the month of May, you can expect as high temperature here as 43 ° C. The sun tends to shine very brightly, and the dry and hot wind known as Loo blows here during most periods. At times, the temperature can be reduced to about 35 ° C by an isolated thunderstorm. There can be some relief, but one can expect drying up all vegetation.
Monsoon Season (July to Mid-September)
During this time, winds laden with moisture bring dark, low rain-bearing clouds. Monsoon usually arrives at Pakistan by the 7th of July, and stays active until the middle of September through July and August. The arrival of monsoon considerably reduces the temperature. Although monsoon helps reduce the temperature a lot, the relative humidity is very high and causes great discomfort to the people here.
Post Monsoon Season (Mid-September to November)
It comes after the monsoon season, and includes half of September, October and November. This is indeed a very dry season, and the driest season in Pakistan. There is very low precipitation with no monsoon clouds passing over the country and no sign of any western disturbances unlike in winter season. At times, the entire season experiences no rainfall. The climate is dry and when skies clear, Pakistan generally witnesses warm days.
