Probability of Precipitation in April
To show variation within the month and not just the monthly total, we show the rainfall accumulated over a sliding 31-day period centered around each day.
The average sliding 31-day rainfall during April in Moscow is increasing, starting the month at 0.7 inches, when it rarely exceeds 1.4 inches or falls below 0.2 inches, and ending the month at 1.4 inches, when it rarely exceeds 2.4 inches or falls below 0.4 inches.
Average Monthly Rainfall in April
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. As with rainfall, we consider the liquid-equivalent snowfall accumulated over a sliding 31-day period centered around each day.
The average sliding 31-day liquid-equivalent snowfall during April in Moscow is essentially constant, remaining about 0.1 inches throughout, and rarely exceeding 0.6 inches or falling to 0.0 inches.

Over the course of April in Moscow, the length of the day is very rapidly increasing. From the start to the end of the month, the length of the day increases by 2 hours, 10 minutes, implying an average daily increase of 4 minutes, 29 seconds, and weekly increase of 31 minutes, 21 seconds.
The shortest day of the month is April 1, with 13 hours, 7 minutes of daylight and the longest day is April 30, with 15 hours, 17 minutes of daylight.
Hours of Daylight and Twilight in April

Sunrise & Sunset with Twilight in April
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 chance that a given day will be muggy in Moscow is essentially constant during April, remaining around 0% throughout.
For reference, on July 11, the muggiest day of the year, there are muggy conditions 5% of the time, while on January 1, the least muggy day of the year, there are muggy conditions 0% of the time.

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 Moscow is essentially constant during April, remaining within 0.2 miles per hour of 5.4 miles per hour throughout.
For reference, on January 25, the windiest day of the year, the daily average wind speed is 6.6 miles per hour, while on July 29, the calmest day of the year, the daily average wind speed is 4.2 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 in Moscow is increasing during April, rising by 1.3 kWh, from 3.5 kWh to 4.8 kWh, over the course of the month.

This report illustrates the typical weather in Moscow year round, 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 Moscow.
For each station, the records are corrected for the elevation difference between that station and Moscow 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 Moscow is computed as the weighted average of the individual contributions from each station, with weights proportional to the inverse of the distance between Moscow and a given station.
The stations contributing to this reconstruction are: Sheremetyevo International Airport (41%, 28 kilometers, northwest); Vnukovo International Airport (38%, 29 kilometers, southwest); and Domodedovo International Airport (22%, 42 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.
