RainfallTo show variation within the season and not just the monthly totals, we show the rainfall accumulated over a sliding 31-day period centered around each day. The average sliding 31-day rainfall during the winter in Yeghegnut is essentially constant, remaining about 0.2 inches throughout, and rarely exceeding 0.6 inches. The lowest average 31-day accumulation is 0.1 inches on January 21. SnowfallAs with rainfall, we consider the snowfall accumulated over a sliding 31-day period centered around each day. The average sliding 31-day snowfall during the winter in Yeghegnut is gradually increasing, starting the season at 1.5 inches, when it rarely exceeds 4.1 inches, and ending the season at 2.0 inches, when it rarely exceeds 5.1 inches. The highest average 31-day accumulation is 2.5 inches on February 8. SunOver the course of the winter in Yeghegnut, the length of the day is rapidly increasing. From the start to the end of the season, the length of the day increases by 1 hour, 47 minutes, implying an average daily increase of 1 minute, 12 seconds, and weekly increase of 8 minutes, 25 seconds. The shortest day of the winter is December 21, with 9 hours, 14 minutes of daylight and the longest day is February 28, with 11 hours, 14 minutes of daylight. The latest sunrise of the winter in Yeghegnut is 8:26 AM on January 3 and the earliest sunrise is 49 minutes earlier at 7:37 AM on February 28. The earliest sunset is 5:33 PM on December 7 and the latest sunset is 1 hour, 18 minutes later at 6:51 PM on February 28. Daylight saving time is not observed in Yeghegnut during 2024. For reference, on June 20, the longest day of the year, the Sun rises at 5:29 AM and sets 15 hours, 7 minutes later, at 8:36 PM, while on December 21, the shortest day of the year, it rises at 8:22 AM and sets 9 hours, 14 minutes later, at 5:36 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 winter 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 Yeghegnut is essentially constant during the winter, remaining around 0% throughout. For reference, on August 3, 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 Yeghegnut is essentially constant during the winter, remaining within 0.5 miles per hour of 6.7 miles per hour throughout. For reference, on January 18, the windiest day of the year, the daily average wind speed is 7.2 miles per hour, while on September 27, the calmest day of the year, the daily average wind speed is 4.4 miles per hour. The highest daily average wind speed during the winter is 7.2 miles per hour on January 18. The wind direction in Yeghegnut during the winter is predominantly out of the south from December 1 to February 11 and the west from February 11 to February 28. 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 Yeghegnut typically lasts for 6.4 months (196 days), from around April 13 to around October 26, rarely starting before March 24 or after May 8, and rarely ending before October 5 or after November 13. The winter in Yeghegnut is reliably fully outside of 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 Yeghegnut are very rapidly decreasing during the winter, decreasing by 2,530°F, from 2,531°F to 1°F, over the course of the season. 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.

Data SourcesThis report illustrates the typical weather in Yeghegnut, 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 3 weather stations near enough to contribute to our estimation of the temperature and dew point in Yeghegnut. For each station, the records are corrected for the elevation difference between that station and Yeghegnut 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 Yeghegnut is computed as the weighted average of the individual contributions from each station, with weights proportional to the inverse of the distance between Yeghegnut 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 Yeghegnut 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.
