The clearest day of the spring is May 31, with clear, mostly clear, or partly cloudy conditions 51% of the time. For reference, on January 24, the cloudiest day of the year, the chance of overcast or mostly cloudy conditions is 83%, while on July 17, the clearest day of the year, the chance of clear, mostly clear, or partly cloudy skies is 55%. PrecipitationA wet day is one with at least 0.04 inches of liquid or liquid-equivalent precipitation. In Lyuban’, the chance of a wet day over the course of the spring is very rapidly increasing, starting the season at 17% and ending it at 32%. For reference, the year's highest daily chance of a wet day is 37% on June 24, and its lowest chance is 17% on February 26. Over the course of the spring in Lyuban’, the chance of a day with only rain increases from 7% to 32%, the chance of a day with mixed snow and rain decreases from 4% to 0%, and the chance of a day with only snow decreases from 7% to 0%. RainfallTo show variation within the season and not just the monthly totals, we show the rainfall accumulated over a sliding 31-day period centered around each day. The average sliding 31-day rainfall during the spring in Lyuban’ is very rapidly increasing, starting the season at 0.4 inches, when it rarely exceeds 1.0 inches, and ending the season at 2.5 inches, when it rarely exceeds 4.3 inches or falls below 1.0 inches. SnowfallAs with rainfall, we consider the snowfall accumulated over a sliding 31-day period centered around each day. The average sliding 31-day snowfall during the spring in Lyuban’ is rapidly decreasing, starting the season at 3.6 inches, when it rarely exceeds 6.7 inches or falls below 0.6 inches, and ending the season at 0.0 inches, when it rarely exceeds 0.0 inches or falls below -0.0 inches. SunOver the course of the spring in Lyuban’, the length of the day is very rapidly increasing. From the start to the end of the season, the length of the day increases by 7 hours, 31 minutes, implying an average daily increase of 4 minutes, 57 seconds, and weekly increase of 34 minutes, 40 seconds. The shortest day of the spring is March 1, with 10 hours, 33 minutes of daylight and the longest day is May 31, with 18 hours, 4 minutes of daylight. The latest sunrise of the spring in Lyuban’ is 7:51 AM on March 1 and the earliest sunrise is 4 hours, 0 minutes earlier at 3:51 AM on May 31. The earliest sunset is 6:24 PM on March 1 and the latest sunset is 3 hours, 31 minutes later at 9:55 PM on May 31. Daylight saving time is not observed in Lyuban’ during 2024. For reference, on June 20, the longest day of the year, the Sun rises at 3:37 AM and sets 18 hours, 38 minutes later, at 10:15 PM, while on December 21, the shortest day of the year, it rises at 9:51 AM and sets 6 hours, 4 minutes later, at 3:55 PM. The figure below presents a compact representation of the sun's elevation (the angle of the sun above the horizon) and azimuth (its compass bearing) for every hour of every day in the reporting period. The horizontal axis is the day of the year and the vertical axis is the hour of the day. For a given day and hour of that day, the background color indicates the azimuth of the sun at that moment. The black isolines are contours of constant solar elevation. MoonThe figure below presents a compact representation of key lunar data for the spring of 2024. The horizontal axis is the day, the vertical axis is the hour of the day, and the colored areas indicate when the moon is above the horizon. The vertical gray bars (new Moons) and blue bars (full Moons) indicate key Moon phases. The label associated with each bar indicates the date and time that the phase is obtained, and the companion time labels indicate the rise and set times of the Moon for the nearest time interval in which the moon is above the horizon. HumidityWe 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 Lyuban’ is essentially constant during the spring, remaining around 0% throughout. For reference, on July 24, the muggiest day of the year, there are muggy conditions 6% of the time, while on January 1, the least muggy day of the year, there are muggy conditions 0% of the time. WindThis 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 Lyuban’ is decreasing during the spring, decreasing from 5.6 miles per hour to 4.3 miles per hour over the course of the season. For reference, on January 24, the windiest day of the year, the daily average wind speed is 6.0 miles per hour, while on July 22, the calmest day of the year, the daily average wind speed is 3.8 miles per hour. The wind direction in Lyuban’ during the spring is predominantly out of the south from March 1 to April 22 and the west from April 22 to May 31. Growing SeasonDefinitions of the growing season vary throughout the world, but for the purposes of this report, we define it as the longest continuous period of non-freezing temperatures (≥ 32°F) in the year (the calendar year in the Northern Hemisphere, or from July 1 until June 30 in the Southern Hemisphere). The growing season in Lyuban’ typically lasts for 4.6 months (141 days), from around May 10 to around September 28, rarely starting before April 20 or after June 1, and rarely ending before September 3 or after October 19. During the spring in Lyuban’, the chance that a given day is within the growing season is very rapidly increasing rising from 0% to 89% over the course of the season. Growing degree days are a measure of yearly heat accumulation used to predict plant and animal development, and defined as the integral of warmth above a base temperature, discarding any excess above a maximum temperature. In this report, we use a base of 50°F and a cap of 86°F. The average accumulated growing degree days in Lyuban’ are increasing during the spring, increasing by 228°F, from 0°F to 228°F, over the course of the season. Solar EnergyThis 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 Lyuban’ is very rapidly increasing during the spring, rising by 4.2 kWh, from 1.6 kWh to 5.8 kWh, over the course of the season.

Data SourcesThis report illustrates the typical weather in Lyuban’, based on a statistical analysis of historical hourly weather reports and model reconstructions from January 1, 1980 to December 31, 2016. Temperature and Dew PointThere is only a single weather station, Pulkovo Airport, in our network suitable to be used as a proxy for the historical temperature and dew point records of Lyuban’. At a distance of 73 kilometers from Lyuban’, 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 Lyuban’ 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 DataAll data relating to the Sun's position (e.g., sunrise and sunset) are computed using astronomical formulas from the book, Astronomical Algorithms 2nd Edition , 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.

Weather data is prone to errors, outages, and other defects. We assume no responsibility for any decisions made on the basis of the content presented on this site. We draw particular cautious attention to our reliance on the MERRA-2 model-based reconstructions for a number of important data series. While having the tremendous advantages of temporal and spatial completeness, these reconstructions: (1) are based on computer models that may have model-based errors, (2) are coarsely sampled on a 50 km grid and are therefore unable to reconstruct the local variations of many microclimates, and (3) have particular difficulty with the weather in some coastal areas, especially small islands. We further caution that our travel scores are only as good as the data that underpin them, that weather conditions at any given location and time are unpredictable and variable, and that the definition of the scores reflects a particular set of preferences that may not agree with those of any particular reader.
