SunOver the course of the spring in Semenivka, the length of the day is very rapidly increasing. From the start to the end of the season, the length of the day increases by 4 hours, 59 minutes, implying an average daily increase of 3 minutes, 17 seconds, and weekly increase of 22 minutes, 58 seconds. The shortest day of the spring is March 1, with 11 hours, 1 minute of daylight and the longest day is May 31, with 16 hours, 0 minutes of daylight. The latest sunrise of the spring in Semenivka is 6:29 AM on March 1 and the earliest sunrise is 1 hour, 44 minutes earlier at 4:45 AM on May 31. The earliest sunset is 5:30 PM on March 1 and the latest sunset is 3 hours, 15 minutes later at 8:45 PM on May 31. Daylight saving time (DST) ends at 4:00 AM on March 31, 2024, shifting sunrise and sunset to be an hour earlier. For reference, on June 20, the longest day of the year, the Sun rises at 4:39 AM and sets 16 hours, 18 minutes later, at 8:58 PM, while on December 21, the shortest day of the year, it rises at 7:41 AM and sets 8 hours, 8 minutes later, at 3:49 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 the spring of 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 Semenivka is essentially constant during the spring, remaining within 1% of 1% throughout. For reference, on July 20, the muggiest day of the year, there are muggy conditions 10% of the time, while on October 12, 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 Semenivka is rapidly decreasing during the spring, decreasing from 11.1 miles per hour to 8.7 miles per hour over the course of the season. For reference, on March 9, the windiest day of the year, the daily average wind speed is 11.2 miles per hour, while on July 26, the calmest day of the year, the daily average wind speed is 8.4 miles per hour. The highest daily average wind speed during the spring is 11.2 miles per hour on March 9. The lowest daily average wind speed during the spring is 8.7 miles per hour on May 30. The hourly average wind direction in Semenivka throughout the spring is predominantly from the east, with a peak proportion of 31% on April 14. 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 Semenivka typically lasts for 6.0 months (184 days), from around April 14 to around October 15, rarely starting before March 25 or after May 5, and rarely ending before September 26 or after November 3. During the spring in Semenivka, the chance that a given day is within the growing season is very rapidly increasing rising from 0% to 100% over the course of the 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 Semenivka are rapidly increasing during the spring, increasing by 459°F, from 0°F to 459°F, over the course of the season.

Data SourcesThis report illustrates the typical weather in Semenivka, 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 are 2 weather stations near enough to contribute to our estimation of the temperature and dew point in Semenivka. For each station, the records are corrected for the elevation difference between that station and Semenivka according to the International Standard Atmosphere , and by the relative change present in the MERRA-2 satellite-era reanalysis between the two locations. The estimated value at Semenivka is computed as the weighted average of the individual contributions from each station, in addition to a contribution from the MERRA-2 reconstruction, corrected for the difference between the reference elevation of the MERRA-2 grid cell and the elevation of Semenivka. The station weights are proportional to the inverse of the distance between Semenivka and a given station. The weight assigned to the MERRA-2 value depends on the distance from Semenivka to the nearest station, increasing from 0% at 150 kilometers to 100% at 200 kilometers. In this case, the MERRA-2 weight is 31%. The stations contributing to this reconstruction are:
To get a sense of how much these sources agree with each other, you can view a comparison of Semenivka and the stations that contribute to our estimates of its temperature history and climate. Please note that each source's contribution is adjusted for elevation and the relative change present in the MERRA-2 data. 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.
