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 of the year. Kiev experiences significant seasonal variation in monthly rainfall.
The rainy period of the year lasts for 10 months, from February 17 to December 28, with a sliding 31-day rainfall of at least 0.5 inches. The most rain falls during the 31 days centered around June 26, with an average total accumulation of 2.6 inches.
The rainless period of the year lasts for 1.6 months, from December 28 to February 17. The least rain falls around January 15, with an average total accumulation of 0.4 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 of the year. Kiev experiences some seasonal variation in monthly liquid-equivalent snowfall.
The snowy period of the year lasts for 5.2 months, from October 29 to April 4, with a sliding 31-day liquid-equivalent snowfall of at least 0.1 inches. The most snow falls during the 31 days centered around December 19, with an average total liquid-equivalent accumulation of 0.5 inches.
The snowless period of the year lasts for 6.8 months, from April 4 to October 29. The least snow falls around July 27, with an average total liquid-equivalent accumulation of 0.0 inches.

Sunrise & Sunset with Twilight and Daylight Saving Time
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 Kiev, 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, staying within 4% of 4% throughout.

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 Kiev experiences mild seasonal variation over the course of the year.
The windier part of the year lasts for 6.6 months, from October 6 to April 24, with average wind speeds of more than 5.1 miles per hour. The windiest day of the year is January 25, with an average hourly wind speed of 6.0 miles per hour.
The calmer time of year lasts for 5.4 months, from April 24 to October 6. The calmest day of the year is July 27, with an average hourly wind speed of 4.3 miles per hour.
Average Wind Speed
The predominant average hourly wind direction in Kiev varies throughout the year.

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 3.7 months, from April 30 to August 22, with an average daily incident shortwave energy per square meter above 5.3 kWh. The brightest day of the year is June 22, with an average of 6.5 kWh.
The darker period of the year lasts for 3.7 months, from October 26 to February 17, with an average daily incident shortwave energy per square meter below 2.0 kWh. The darkest day of the year is December 20, with an average of 0.8 kWh.

This report illustrates the typical weather in Kiev, 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 are 3 weather stations near enough to contribute to our estimation of the temperature and dew point in Kiev.
For each station, the records are corrected for the elevation difference between that station and Kiev 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 Kiev is computed as the weighted average of the individual contributions from each station, with weights proportional to the inverse of the distance between Kiev and a given station.
The stations contributing to this reconstruction are: Kyiv Zhuliany International Airport (72%, 8 kilometers, southwest); Gostomel Airport (14%, 29 kilometers, northwest); and Kiev Boryspil International Airport (14%, 29 kilometers, southeast).
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.
