A wet day is one with at least 0.04 inches of liquid or liquid-equivalent precipitation. The chance of wet days in Tashkent varies throughout the year.
The wetter season lasts 211 days, from October 24 to May 23, with a greater than 12% chance of a given day being a wet day. The chance of a wet day peaks at 23% on February 8.
The drier season lasts 154 days, from May 23 to October 24. The smallest chance of a wet day is 1% on August 25.
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 22% on March 30.
Daily Chance of Precipitation
To show variation within the months and not just the monthly totals, we show the rainfall accumulated over a sliding 31-day period centered around each day in the year. Tashkent experiences some seasonal variation in monthly rainfall.
The rainy period of the year lasts for 238 days, from October 9 to June 4, with a sliding 31-day rainfall of at least 0.5 inches. The most rain falls during the 31 days centered around April 1, with an average total accumulation of 1.4 inches.
The rainless period of the year lasts for 127 days, from June 4 to October 9. The least rain falls around August 22, with and average total accumulation of 0.0 inches.
Average Monthly Rainfall
We report snowfall in liquid-equivalent terms. The actual depth of new snowfall is typically between 5 and 10 times the liquid-equivalent amount, assuming the ground is frozen. Colder, drier snow tends to be on the higher end of that range and warmer, wetter snow on the lower end.
As with rainfall, we consider the snowfall accumulated over a sliding 31-day period centered around each day in the year. Tashkent experiences some seasonal variation in monthly liquid-equivalent snowfall.
The snowy period of the year lasts for 121 days, from November 15 to March 16, with a sliding 31-day liquid-equivalent snowfall of at least 0.1 inches. The most snow falls during the 31 days centered around February 1, with an average total liquid-equivalent accumulation of 0.3 inches.
The snowless period of the year lasts for 244 days, from March 16 to November 15. The least snow falls around July 13, with an average total liquid-equivalent accumulation of 0.0 inches.
Average Liquid-Equivalent Monthly Snowfall
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.
The perceived humidity level in Tashkent, as measured by the percentage of time in which the humidity comfort level is muggy, oppressive, or miserable, does not vary significantly over the course of the year, remaining a virtually constant 0% throughout.
Humidity Comfort Levels
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 Tashkent experiences mildly seasonal variation over the course of the year.
The windier part of the year lasts for 143 days, from May 5 to September 25, with average wind speeds of more than 3.4 miles per hour. The windiest day of the year is July 11, with an average hourly wind speed of 4.1 miles per hour.
The calmer time of year lasts for 222 days, from September 25 to May 5. The calmest day of the year is December 17, with an average hourly wind speed of 2.7 miles per hour.

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 very significant seasonal variation over the course of the year.
The brighter period of the year lasts for 105 days, from May 13 to August 26, with an average daily incident shortwave energy per square meter above 7.0 kWh. The brightest day of the year is June 27, with an average of 8.3 kWh.

Temperature and Dew Point
There are 2 weather stations near enough to contribute to our estimation of the temperature and dew point in Tashkent.
For each station, the records are are corrected for the elevation difference between that station and Tashkent according to the International Standard Atmosphere , and by the relative change present in the MERRA-2 satellite-era reanalysis between the two locations.
The estimated value at Tashkent is computed as the weighted average of the individual contributions from each station, with weights proportional to the inverse of the distance between Tashkent and a given station.
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.
