Very high altitudes modify the climate in the cold, snow-covered northern mountains; temperatures on the [[Balochistan, Pakistan|Balochistan]] plateau are somewhat higher. Along the coastal strip, the climate is modified by sea breeze. In the rest of the country, temperatures reach great heights in the summer; the mean temperature during June is {{convert|38|°C|F}} in the plains, the highest temperatures can exceed {{convert|53|°C}}. During summer, hot winds called [[Loo (wind)|Loo]] blow across the plains during the day. Trees shed their leaves to avoid loss of moisture. Pakistan recorded one of the highest temperatures in the world, 53.7 °C (128.66 °F) on 28 May 2017, the hottest temperature ever recorded in Pakistan and also the second hottest measured temperature ever recorded in [[Asia]].<ref name="public.wmo.int">{{Cite web|title=WMO verifies 3rd and 4th hottest temperature recorded on Earth|url=https://public-old.wmo.int/en/media/press-release/wmo-verifies-3rd-and-4th-hottest-temperature-recorded-earth|archive-url=https://web.archive.org/web/20231218172054/https://public-old.wmo.int/en/media/press-release/wmo-verifies-3rd-and-4th-hottest-temperature-recorded-earth|url-status=dead|archive-date=18 December 2023|date=2019-06-18|website=World Meteorological Organization|language=en|access-date=2020-05-08}}</ref>
The dry, hot weather is broken occasionally by dust storms and thunderstorms that temporarily lower the temperature. Evenings are cool; the daily variation in temperature may be as much as 11 °C to 17 °C. Winters are cold, with minimum mean temperatures in [[Punjab, Pakistan|Punjab]] of about {{convert|4|°C}} in January, and sub-zero temperatures in the far north and [[Balochistan]].
Winters are extremely cold in the north and the milder they get the more you go to the south. Spring causes heavy rainfall in the northern parts while it is mild in most parts of Pakistan. Summers are sweltering, boiling and extremely hot in central Balochistan, southern Punjab and Upper Sindh while it gets milder the more you go to the north and the coast. The Monsoon season (late June-late September) also occurs in the summer season.
Autumn is pleasant but gets cooler day by day with almost no rainfall. Winter in some parts even starts in late October-early November.

Pakistan has four seasons: a cool and cold winter from December through February; a pleasant spring from March through May; the summer rainy season, or southwest monsoon period, from June through September; and dry autumn period of October and November. The onset and duration of these seasons vary greatly according to location.
The climate in the capital city of Islamabad varies from an average daily low of 2 °C in January to an average daily high of 38 °C in June. Half of the annual rainfall occurs in July and August, averaging about 255 millimeters in each of those two months. The remainder of the year has significantly less rain, amounting to about fifty millimeters per month. Hailstorms are common in the spring.
