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 September in Yermentau is essentially constant, remaining about 0.7 inches throughout, and rarely exceeding 1.5 inches or falling below 0.1 inches. SunOver the course of September in Yermentau, the length of the day is rapidly decreasing. From the start to the end of the month, the length of the day decreases by 1 hour, 53 minutes, implying an average daily decrease of 3 minutes, 54 seconds, and weekly decrease of 27 minutes, 21 seconds. The shortest day of the month is September 30, with 11 hours, 40 minutes of daylight and the longest day is September 1, with 13 hours, 33 minutes of daylight. The earliest sunrise of the month in Yermentau is 6:20 AM on September 1 and the latest sunrise is 47 minutes later at 7:06 AM on September 30. The latest sunset is 7:53 PM on September 1 and the earliest sunset is 1 hour, 7 minutes earlier at 6:47 PM on September 30. Daylight saving time is not observed in Yermentau during 2024. For reference, on June 20, the longest day of the year, the Sun rises at 4:49 AM and sets 16 hours, 40 minutes later, at 9:29 PM, while on December 21, the shortest day of the year, it rises at 9:11 AM and sets 7 hours, 48 minutes later, at 5:00 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 September 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 Yermentau is essentially constant during September, remaining around 0% throughout. For reference, on July 12, the muggiest day of the year, there are muggy conditions 1% 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 Yermentau is increasing during September, increasing from 9.8 miles per hour to 10.8 miles per hour over the course of the month. For reference, on January 1, the windiest day of the year, the daily average wind speed is 14.3 miles per hour, while on July 21, the calmest day of the year, the daily average wind speed is 8.7 miles per hour. The hourly average wind direction in Yermentau throughout September is predominantly from the west, with a peak proportion of 47% on September 30. 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 Yermentau typically lasts for 4.1 months (127 days), from around May 12 to around September 16, rarely starting before April 23 or after June 1, and rarely ending before August 30 or after October 4. During September in Yermentau, the chance that a given day is within the growing season is very rapidly decreasing falling from 87% to 16% 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 Yermentau are gradually increasing during September, increasing by 169°F, from 1,741°F to 1,910°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 Yermentau is rapidly decreasing during September, falling by 1.7 kWh, from 4.8 kWh to 3.2 kWh, over the course of the month.

Data SourcesThis report illustrates the typical weather in Yermentau, 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, Astana International Airport, in our network suitable to be used as a proxy for the historical temperature and dew point records of Yermentau. At a distance of 132 kilometers from Yermentau, 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 Yermentau 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.
