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 February in Ruoshui is increasing, starting the month at 1.2 inches, when it rarely exceeds 2.2 inches or falls below 0.2 inches, and ending the month at 2.1 inches, when it rarely exceeds 3.7 inches or falls below 0.7 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 February in Ruoshui is gradually decreasing, starting the month at 1.5 inches, when it rarely exceeds 4.6 inches or falls below -0.0 inches, and ending the month at 0.6 inches, when it rarely exceeds 1.6 inches or falls below -0.0 inches. SunOver the course of February in Ruoshui, the length of the day is increasing. From the start to the end of the month, the length of the day increases by 40 minutes, implying an average daily increase of 1 minute, 26 seconds, and weekly increase of 10 minutes, 5 seconds. The shortest day of the month is February 1, with 10 hours, 55 minutes of daylight and the longest day is February 29, with 11 hours, 36 minutes of daylight. The latest sunrise of the month in Ruoshui is 7:26 AM on February 1 and the earliest sunrise is 21 minutes earlier at 7:05 AM on February 29. The earliest sunset is 6:21 PM on February 1 and the latest sunset is 19 minutes later at 6:40 PM on February 29. Daylight saving time is not observed in Ruoshui during 2024. For reference, on June 20, the longest day of the year, the Sun rises at 5:46 AM and sets 13 hours, 51 minutes later, at 7:37 PM, while on December 21, the shortest day of the year, it rises at 7:25 AM and sets 10 hours, 26 minutes later, at 5:51 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 February 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 Ruoshui is essentially constant during February, remaining around 0% throughout. For reference, on July 9, the muggiest day of the year, there are muggy conditions 99% 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 Ruoshui is gradually increasing during February, increasing from 6.0 miles per hour to 6.6 miles per hour over the course of the month. For reference, on March 9, the windiest day of the year, the daily average wind speed is 6.8 miles per hour, while on August 21, the calmest day of the year, the daily average wind speed is 4.8 miles per hour. The hourly average wind direction in Ruoshui throughout February is predominantly from the east, with a peak proportion of 51% on February 2. 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 Ruoshui typically lasts for 9.6 months (292 days), from around February 21 to around December 9, rarely starting before January 28 or after March 13, and rarely ending before November 20 or after December 29. During February in Ruoshui, the chance that a given day is within the growing season is very rapidly increasing rising from 15% to 67% 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 Ruoshui are gradually increasing during February, increasing by 91°F, from 45°F to 136°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 Ruoshui is gradually increasing during February, rising by 0.5 kWh, from 3.2 kWh to 3.7 kWh, over the course of the month.

Data SourcesThis report illustrates the typical weather in Ruoshui, based on a statistical analysis of historical hourly weather reports and model reconstructions from January 1, 1980 to December 31, 2016. Ruoshui is further than 200 kilometers from the nearest reliable weather station, so the weather-related data on this page were taken entirely from NASA's MERRA-2 satellite-era reanalysis . 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. The temperature and dew point estimates are corrected for the difference between the reference elevation of the MERRA-2 grid cell and the elevation of Ruoshui, according to the International Standard Atmosphere . All 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. 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.
