RainfallTo 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 May in Amursk is increasing, starting the month at 1.3 inches, when it rarely exceeds 2.4 inches or falls below 0.4 inches, and ending the month at 1.9 inches, when it rarely exceeds 3.3 inches or falls below 0.9 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 May in Amursk is decreasing, starting the month at 1.1 inches, when it rarely exceeds 3.1 inches or falls below -0.0 inches, and ending the month at 0.0 inches, when it rarely exceeds 0.1 inches or falls below -0.0 inches. SunOver the course of May in Amursk, the length of the day is rapidly increasing. From the start to the end of the month, the length of the day increases by 1 hour, 21 minutes, implying an average daily increase of 2 minutes, 42 seconds, and weekly increase of 18 minutes, 57 seconds. The shortest day of the month is May 1, with 14 hours, 44 minutes of daylight and the longest day is May 31, with 16 hours, 5 minutes of daylight. The latest sunrise of the month in Amursk is 5:28 AM on May 1 and the earliest sunrise is 40 minutes earlier at 4:47 AM on May 31. The earliest sunset is 8:12 PM on May 1 and the latest sunset is 41 minutes later at 8:53 PM on May 31. Daylight saving time is not observed in Amursk during 2024. For reference, on June 20, the longest day of the year, the Sun rises at 4:41 AM and sets 16 hours, 25 minutes later, at 9:06 PM, while on December 21, the shortest day of the year, it rises at 8:49 AM and sets 8 hours, 2 minutes later, at 4:51 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 May 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 Amursk is essentially constant during May, remaining within 1% of 1% throughout. For reference, on July 28, the muggiest day of the year, there are muggy conditions 35% of the time, while on October 4, 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 Amursk is gradually decreasing during May, decreasing from 7.4 miles per hour to 6.5 miles per hour over the course of the month. For reference, on April 19, the windiest day of the year, the daily average wind speed is 7.7 miles per hour, while on July 19, the calmest day of the year, the daily average wind speed is 5.6 miles per hour. The wind direction in Amursk during May is predominantly out of the north from May 1 to May 24 and the south from May 24 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 Amursk typically lasts for 5.0 months (154 days), from around May 3 to around October 3, rarely starting before April 16 or after May 20, and rarely ending before September 18 or after October 18. During May in Amursk, the chance that a given day is within the growing season is very rapidly increasing rising from 45% to 98% over the course of the month. 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 Amursk are gradually increasing during May, increasing by 168°F, from 26°F to 194°F, over the course of the month. 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 Amursk is gradually increasing during May, rising by 0.9 kWh, from 5.0 kWh to 5.9 kWh, over the course of the month.

Data SourcesThis report illustrates the typical weather in Amursk, 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, Troickoe, in our network suitable to be used as a proxy for the historical temperature and dew point records of Amursk. At a distance of 90 kilometers from Amursk, 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 Amursk 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.
