Temperature

The standard measuring conditions for temperature are 1.2 meters above the ground out of direct sunlight (hence the term, x degrees "in the shade").

High temperature

Heat waves mostly occur during summer months but in southern Pakistan heat waves occur at any time period between April and September and bring high temperatures but most powerful heat waves occur in May and June. Some areas of southern Pakistan usually experience above 50 °C temperature and play havoc in these areas. The most deadly heat wave in the history of Pakistan is the record-breaking heat wave of summer 2010 which occurred in the last ten days of May.

Precipitation

The standard way of measuring Rainfall or Snowfall is the standard Rain gauge, which can be found in 100-mm (4-in) plastic and 200-mm (8-in) metal varieties. The inner cylinder is filled by 25 mm (0.98 in) of Rain, with overflow flowing into the outer cylinder. Plastic gauges have markings on the inner cylinder down to 0.25 mm (0.0098 in) resolution, while metal gauges require use of a stick designed with the appropriate 0.25 mm (0.0098 in) markings. After the inner cylinder is filled, the amount inside it is discarded, then filled with the remaining Rainfall in the outer cylinder until all the fluid in the outer cylinder is gone, adding to the overall total until the outer cylinder is empty.

Rainfall

Pakistan receives Rainfall from both Monsoon and Western Disturbance. Monsoon occurs from July to September and brings heavy Downpour across the country except western Balochistan. Western Disturbances occur from October to May and bring Rainfall across the country with some heavy Downpour in northern Pakistan. But in June Western Disturbances occasionally hit the northern parts of the country. Pre-Monsoon also occurs in this month occasionally but not always.

In the month of July Pakistan received below normal monsoon rains; however, in August and September the country received above normal monsoon rains.

Khyber Pakhtunkhwa and North eastern Punjab were badly affected during the monsoon rains when dams, rivers and lakes overflowed. By mid-August, according to the governmental Federal Flood Commission (FFC), the floods had caused the deaths of at least 1,540 people, while 2,088 people had received injuries, 557,226 houses had been destroyed, and over 6 million people had been displaced.^[76] One month later, the data had been updated to reveal 1,781 deaths, 2,966 people with injuries, and more than 1.89 million homes destroyed.^[77] The flood affected more than 20 million people exceeding the combined total of individuals affected by the 2004 Indian Ocean tsunami, the 2005 Kashmir earthquake and the 2010 Haiti earthquake.^[78][79] The flood is considered as worst in Pakistan's history affecting people of all four provinces and Gilgit Baltistan and Azad Kashmir region of Pakistan.^[80]
