A wet day is one with at least 0.04 inches of liquid or liquid-equivalent precipitation. The chance of wet days in Kaunas varies throughout the year.
The wetter season lasts 7.3 months, from May 18 to December 26, with a greater than 27% chance of a given day being a wet day. The chance of a wet day peaks at 35% on June 30.
The drier season lasts 4.7 months, from December 26 to May 18. The smallest chance of a wet day is 19% on February 28.
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 35% on June 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. Kaunas experiences some seasonal variation in monthly rainfall.
Rain falls throughout the year in Kaunas. The most rain falls during the 31 days centered around July 3, with an average total accumulation of 2.7 inches.
The least rain falls around February 22, with and average total accumulation of 0.7 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. Kaunas experiences some seasonal variation in monthly liquid-equivalent snowfall.
The snowy period of the year lasts for 4.8 months, from November 9 to April 3, 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 23, with an average total liquid-equivalent accumulation of 0.4 inches.
The snowless period of the year lasts for 7.2 months, from April 3 to November 9. The least snow falls around July 17, 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 Kaunas, 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 3% of 3% 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 Kaunas experiences mildly seasonal variation over the course of the year.
The windier part of the year lasts for 5.7 months, from October 15 to April 7, with average wind speeds of more than 3.8 miles per hour. The windiest day of the year is January 24, with an average hourly wind speed of 4.6 miles per hour.
The calmer time of year lasts for 6.3 months, from April 7 to October 15. The calmest day of the year is August 7, with an average hourly wind speed of 3.0 miles per hour.
Average Wind Speed
The predominant average hourly wind direction in Kaunas 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 very significant seasonal variation over the course of the year.
The brighter period of the year lasts for 3.5 months, from May 1 to August 17, with an average daily incident shortwave energy per square meter above 5.0 kWh. The brightest day of the year is June 18, with an average of 6.2 kWh.
The darker period of the year lasts for 4.0 months, from October 20 to February 21, with an average daily incident shortwave energy per square meter below 1.6 kWh. The darkest day of the year is December 19, with an average of 0.4 kWh.

Temperature and Dew Point
There is only a single weather station, Kaunas Airport, in our network suitable to be used as a proxy for the historical temperature and dew point records of Kaunas.
At a distance of 13 kilometers from Kaunas, 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 Kaunas 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.
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.
