The clearest day of the month is July 31, with clear, mostly clear, or partly cloudy conditions 67% of the time. For reference, on April 13, the cloudiest day of the year, the chance of overcast or mostly cloudy conditions is 41%, while on September 17, the clearest day of the year, the chance of clear, mostly clear, or partly cloudy skies is 70%. PrecipitationA wet day is one with at least 0.04 inches of liquid or liquid-equivalent precipitation. In Sayn-Ust, the chance of a wet day over the course of July is gradually decreasing, starting the month at 18% and ending it at 15%. For reference, the year's highest daily chance of a wet day is 18% on July 4, and its lowest chance is 0% on January 6. 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 July in Sayn-Ust is essentially constant, remaining about 0.7 inches throughout, and rarely exceeding 1.3 inches or falling below 0.2 inches. The highest average 31-day accumulation is 0.8 inches on July 14. SunOver the course of July in Sayn-Ust, the length of the day is decreasing. From the start to the end of the month, the length of the day decreases by 55 minutes, implying an average daily decrease of 1 minute, 50 seconds, and weekly decrease of 12 minutes, 49 seconds. The shortest day of the month is July 31, with 14 hours, 58 minutes of daylight and the longest day is July 1, with 15 hours, 53 minutes of daylight. The earliest sunrise of the month in Sayn-Ust is 4:49 AM on July 1 and the latest sunrise is 30 minutes later at 5:19 AM on July 31. The latest sunset is 8:42 PM on July 1 and the earliest sunset is 25 minutes earlier at 8:16 PM on July 31. Daylight saving time is not observed in Sayn-Ust during 2024. For reference, on June 20, the longest day of the year, the Sun rises at 4:45 AM and sets 15 hours, 57 minutes later, at 8:42 PM, while on December 21, the shortest day of the year, it rises at 8:26 AM and sets 8 hours, 28 minutes later, at 4:53 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 July 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 Sayn-Ust is essentially constant during July, remaining around 0% throughout. 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 Sayn-Ust is gradually decreasing during July, decreasing from 8.2 miles per hour to 7.7 miles per hour over the course of the month. For reference, on May 7, the windiest day of the year, the daily average wind speed is 9.9 miles per hour, while on January 22, the calmest day of the year, the daily average wind speed is 5.9 miles per hour. The hourly average wind direction in Sayn-Ust throughout July is predominantly from the north, with a peak proportion of 51% on July 1. 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 Sayn-Ust typically lasts for 3.9 months (121 days), from around May 18 to around September 15, rarely starting before April 28 or after June 4, and rarely ending before August 31 or after October 1. The month of July in Sayn-Ust is reliably fully within the growing 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 Sayn-Ust are rapidly increasing during July, increasing by 544°F, from 760°F to 1,303°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 Sayn-Ust is gradually decreasing during July, falling by 0.6 kWh, from 7.3 kWh to 6.8 kWh, over the course of the month.

Data SourcesThis report illustrates the typical weather in Sayn-Ust, based on a statistical analysis of historical hourly weather reports and model reconstructions from January 1, 1980 to December 31, 2016. Sayn-Ust 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 Sayn-Ust, 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.
