Pakistan lies in the temperate zone. The climate is generally varied throughout the country, characterized by hot summers and cool or cold winters. The upper parts of Pakistan usually receive precipitation from the Western Disturbance. From June till September most of the country is lashed by the South West Monsoon.

Pakistan has recorded one of the highest temperatures in the world, Mohenjo-daroo, Sindh, 53.5 °C (128.3 °F) on 26 May, 2010 it is not only the hottest temperature ever recorded in Pakistan, but also the hottest reliably measured temperature ever recorded in the continent of Asia. As Pakistan is located on a great landmass north of the tropic of Cancer (between latitudes 24° and 37° N), it has a continental type of climate characterized by extreme variations of temperature, both seasonally and daily. Very high altitudes modify the climate in the cold, snow-covered northern mountains; temperatures on the Balochistan Plateau are somewhat higher. Along the coastal strip, the climate is modified by sea breezes. In the rest of the country, temperatures reach great heights in the summer; the mean temperature during June is 38 °C (100 °F) in the plains, the highest temperatures can exceed 47 °C (117 °F). In the summer, hot winds called Loo (wind) blow across the plains during the day. Trees shed their leaves to avoid loss of moisture. The dry, hot weather is broken occasionally by dust storms and thunderstorms that temporarily lower the temperature. Evenings are cool; the diurnal variation in temperature may be as much as 11 °C (52 °F) to 17 °C (63 °F). Winters are cold, with minimum mean temperatures in Punjab of about 4 °C (39 °F) in January, and sub-zero temperatures in the far north and Balochistan.
