A wet day is one with at least 0.04 inches of liquid or liquid-equivalent precipitation. The chance of wet days in Islamabad varies very significantly throughout the year.

The wetter season lasts 2.5 months, from June 24 to September 9, with a greater than 30% chance of a given day being a wet day. The chance of a wet day peaks at 55% on July 27.

The drier season lasts 9.5 months, from September 9 to June 24. The smallest chance of a wet day is 5% on November 8.

Among wet days, we distinguish between those that experience rain alone, snow alone, or a mixture of the two. Based on this categorization, the most common form of precipitation throughout the year is rain alone, with a peak probability of 55% on July 27.

We base the humidity comfort level on the dew point, as it determines whether perspiration will evaporate from the skin, thereby cooling the body. Lower dew points feel drier and higher dew points feel more humid. Unlike temperature, which typically varies significantly between night and day, dew point tends to change more slowly, so while the temperature may drop at night, a muggy day is typically followed by a muggy night.

Islamabad experiences extreme seasonal variation in the perceived humidity.

The muggier period of the year lasts for 3.6 months, from June 14 to October 1, during which time the comfort level is muggy, oppressive, or miserable at least 25% of the time. The muggiest day of the year is August 10, with muggy conditions 95% of the time.

The least muggy day of the year is December 17, when muggy conditions are essentially unheard of.

This section discusses the wide-area hourly average wind vector (speed and direction) at 10 meters above the ground. The wind experienced at any given location is highly dependent on local topography and other factors, and instantaneous wind speed and direction vary more widely than hourly averages.

The average hourly wind speed in Islamabad does not vary significantly over the course of the year, remaining within 0.5 miles per hour of 2.8 miles per hour throughout.

The average of mean hourly wind speeds (dark gray line), with 25th to 75th and 10th to 90th percentile bands.

The predominant average hourly wind direction in Islamabad varies throughout the year.

The wind is most often from the west for 2.1 months, from April 23 to June 26, with a peak percentage of 36% on June 14. The wind is most often from the south for 1.7 months, from June 26 to August 16, with a peak percentage of 45% on July 23. The wind is most often from the east for 3.5 months, from August 16 to November 30 and for 4.1 months, from December 19 to April 23, with a peak percentage of 42% on September 6.

Solar Energy

This section discusses the total daily incident shortwave solar energy reaching the surface of the ground over a wide area, taking full account of seasonal variations in the length of the day, the elevation of the Sun above the horizon, and absorption by clouds and other atmospheric constituents. Shortwave radiation includes visible light and ultraviolet radiation.

The average daily incident shortwave solar energy experiences extreme seasonal variation over the course of the year.

The brighter period of the year lasts for 2.8 months, from April 28 to July 23, with an average daily incident shortwave energy per square meter above 7.0 kWh. The brightest day of the year is June 10, with an average of 8.0 kWh.

The darker period of the year lasts for 3.3 months, from November 10 to February 18, with an average daily incident shortwave energy per square meter below 4.0 kWh. The darkest day of the year is December 23, with an average of 2.9 kWh.

Data Sources

This report illustrates the typical weather in Islamabad, based on a statistical analysis of historical hourly weather reports and model reconstructions from January 1, 1980 to December 31, 2016.

Temperature and Dew Point

There is only a single weather station, Benazir Bhutto International Airport, in our network suitable to be used as a proxy for the historical temperature and dew point records of Islamabad.

At a distance of 13 kilometers from Islamabad, closer than our threshold of 150 kilometers, this station is deemed sufficiently nearby to be relied upon as our primary source for temperature and dew point records.

The station records are corrected for the elevation difference between the station and Islamabad according to the International Standard Atmosphere , and by the relative change present in the MERRA-2 satellite-era reanalysis between the two locations.

Please note that the station records themselves may additionally have been back-filled using other nearby stations or the MERRA-2 reanalysis.

Other Data

All data relating to the Sun's position (e.g., sunrise and sunset) are computed using astronomical formulas from the book, Astronomical Tables of the Sun, Moon and Planets , by Jean Meeus.

All other weather data, including cloud cover, precipitation, wind speed and direction, and solar flux, come from NASA's MERRA-2 Modern-Era Retrospective Analysis . This reanalysis combines a variety of wide-area measurements in a state-of-the-art global meteorological model to reconstruct the hourly history of weather throughout the world on a 50-kilometer grid.

Land Use data comes from the Global Land Cover SHARE database , published by the Food and Agriculture Organization of the United Nations.

Elevation data comes from the Shuttle Radar Topography Mission (SRTM) , published by NASA's Jet Propulsion Laboratory.
