SunOver the course of the fall in Donduşeni, the length of the day is very rapidly decreasing. From the start to the end of the season, the length of the day decreases by 4 hours, 43 minutes, implying an average daily decrease of 3 minutes, 9 seconds, and weekly decrease of 22 minutes, 1 second. The shortest day of the fall is November 30, with 8 hours, 40 minutes of daylight and the longest day is September 1, with 13 hours, 23 minutes of daylight. The earliest sunrise of the fall in Donduşeni is 6:27 AM on September 1 and the latest sunrise is 1 hour, 19 minutes later at 7:46 AM on October 26. The latest sunset is 7:50 PM on September 1 and the earliest sunset is 3 hours, 32 minutes earlier at 4:18 PM on November 30. Daylight saving time (DST) ends at 2:00 AM on October 27, 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 5:08 AM and sets 16 hours, 5 minutes later, at 9:13 PM, while on December 21, the shortest day of the year, it rises at 7:57 AM and sets 8 hours, 20 minutes later, at 4:17 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 fall 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 Donduşeni is essentially constant during the fall, remaining within 1% of 1% throughout. For reference, on July 21, the muggiest day of the year, there are muggy conditions 14% of the time, while on October 23, 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 Donduşeni is increasing during the fall, increasing from 8.3 miles per hour to 9.4 miles per hour over the course of the season. For reference, on March 8, the windiest day of the year, the daily average wind speed is 10.3 miles per hour, while on August 7, the calmest day of the year, the daily average wind speed is 7.5 miles per hour. The highest daily average wind speed during the fall is 9.5 miles per hour on November 16. The wind direction in Donduşeni during the fall is predominantly out of the north from September 1 to October 5 and the south from October 5 to November 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 Donduşeni typically lasts for 6.5 months (198 days), from around April 8 to around October 23, rarely starting before March 21 or after April 27, and rarely ending before October 6 or after November 9. During the fall in Donduşeni, the chance that a given day is within the growing season is very rapidly decreasing falling from 100% to -0% 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 Donduşeni are increasing during the fall, increasing by 412°F, from 2,155°F to 2,567°F, over the course of the season.

Data SourcesThis report illustrates the typical weather in Donduşeni, 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 Donduşeni. For each station, the records are corrected for the elevation difference between that station and Donduşeni 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 Donduşeni is computed as the weighted average of the individual contributions from each station, with weights proportional to the inverse of the distance between Donduşeni and a given station. 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 Donduşeni 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.
