SunOver the course of October in Yemil’chyne, 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, 51 minutes, implying an average daily decrease of 3 minutes, 43 seconds, and weekly decrease of 25 minutes, 59 seconds. The shortest day of the month is October 31, with 9 hours, 45 minutes of daylight and the longest day is October 1, with 11 hours, 36 minutes of daylight. The latest sunrise of the month in Yemil’chyne is 7:50 AM on October 26 and the earliest sunrise is 58 minutes earlier at 6:52 AM on October 27. The latest sunset is 6:46 PM on October 1 and the earliest sunset is 2 hours, 2 minutes earlier at 4:44 PM on October 31. Daylight saving time (DST) starts at 3:00 AM on October 27, 2024, shifting sunrise and sunset to be an hour later. For reference, on June 20, the longest day of the year, the Sun rises at 4:54 AM and sets 16 hours, 32 minutes later, at 9:26 PM, while on December 21, the shortest day of the year, it rises at 8:09 AM and sets 7 hours, 56 minutes later, at 4:05 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 October 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 Yemil’chyne is essentially constant during October, remaining around 0% throughout. For reference, on July 21, the muggiest day of the year, there are muggy conditions 8% 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 Yemil’chyne is gradually increasing during October, increasing from 9.6 miles per hour to 10.4 miles per hour over the course of the month. For reference, on January 25, the windiest day of the year, the daily average wind speed is 11.7 miles per hour, while on August 4, the calmest day of the year, the daily average wind speed is 7.9 miles per hour. The hourly average wind direction in Yemil’chyne throughout October is predominantly from the west, with a peak proportion of 37% on October 23. 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 Yemil’chyne typically lasts for 5.7 months (175 days), from around April 19 to around October 11, rarely starting before March 31 or after May 7, and rarely ending before September 23 or after October 29. During October in Yemil’chyne, the chance that a given day is within the growing season is very rapidly decreasing falling from 76% to 8% 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 Yemil’chyne are gradually increasing during October, increasing by 59°F, from 1,967°F to 2,027°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 Yemil’chyne is decreasing during October, falling by 1.4 kWh, from 3.0 kWh to 1.6 kWh, over the course of the month.

Data SourcesThis report illustrates the typical weather in Yemil’chyne, 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, Rivne International Airport, in our network suitable to be used as a proxy for the historical temperature and dew point records of Yemil’chyne. At a distance of 121 kilometers from Yemil’chyne, 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 Yemil’chyne 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.
