Pakistan has three seasons: winter (November to March) is warm and cooled by sea breezes on the coast; summer (April to July) has extreme temperatures and the monsoon season (July to September) has the highest rainfall on the hills. Karachi has little rain. The best time to visit southern Pakistan is between November and March, when the days are cool and clear. The best time to visit northern Pakistan is from April to October.

Lightweights, with warmer clothing for upland areas in the winter. Rainwear is advised for the monsoon season.
