The figure below shows you a compact characterization of the hourly average winter temperatures. The horizontal axis is the day, the vertical axis is the hour of the day, and the color is the average temperature for that hour and day. Healy, Alaska, United States (3,908 miles away) and Watson Lake, Yukon, Canada (4,517 miles) are the far-away foreign places with temperatures most similar to Tegsh (view comparison).

The highest chance of overcast or mostly cloudy conditions is 47% on December 18. The lowest chance of overcast or mostly cloudy conditions is 40% on January 25. The clearest day of the winter is January 25, with clear, mostly clear, or partly cloudy conditions 60% of the time. For reference, on April 13, the cloudiest day of the year, the chance of overcast or mostly cloudy conditions is 48%, while on September 17, the clearest day of the year, the chance of clear, mostly clear, or partly cloudy skies is 64%. PrecipitationA wet day is one with at least 0.04 inches of liquid or liquid-equivalent precipitation. In Tegsh, the chance of a wet day over the course of the winter is essentially constant, remaining around 1% throughout. For reference, the year's highest daily chance of a wet day is 28% on July 25, and its lowest chance is 0% on February 27. SunOver the course of the winter in Tegsh, 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 2 hours, 23 minutes, implying an average daily increase of 1 minute, 37 seconds, and weekly increase of 11 minutes, 17 seconds. The shortest day of the winter is December 21, with 8 hours, 16 minutes of daylight and the longest day is February 28, with 10 hours, 58 minutes of daylight. The latest sunrise of the winter in Tegsh is 8:29 AM on January 1 and the earliest sunrise is 1 hour, 9 minutes earlier at 7:20 AM on February 28. The earliest sunset is 4:39 PM on December 11 and the latest sunset is 1 hour, 38 minutes later at 6:17 PM on February 28. Daylight saving time is not observed in Tegsh during 2024. For reference, on June 20, the longest day of the year, the Sun rises at 4:32 AM and sets 16 hours, 10 minutes later, at 8:42 PM, while on December 21, the shortest day of the year, it rises at 8:26 AM and sets 8 hours, 16 minutes later, at 4:42 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 Tegsh is essentially constant during the winter, remaining around 0% throughout. 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 Tegsh is essentially constant during the winter, remaining within 0.5 miles per hour of 7.8 miles per hour throughout. For reference, on April 29, the windiest day of the year, the daily average wind speed is 10.3 miles per hour, while on August 4, the calmest day of the year, the daily average wind speed is 7.1 miles per hour. The lowest daily average wind speed during the winter is 7.3 miles per hour on January 24. The hourly average wind direction in Tegsh throughout the winter is predominantly from the south, with a peak proportion of 64% on December 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 Tegsh typically lasts for 2.4 months (74 days), from around June 10 to around August 23, rarely starting before May 22 or after July 2, and rarely ending before August 4 or after September 10. The winter in Tegsh 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 Tegsh are rapidly decreasing during the winter, decreasing by 859°F, from 859°F to 0°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. Shortwave radiation includes visible light and ultraviolet radiation. The average daily incident shortwave solar energy in Tegsh is rapidly increasing during the winter, rising by 2.0 kWh, from 1.6 kWh to 3.5 kWh, over the course of the season. The lowest average daily incident shortwave solar energy during the winter is 1.4 kWh on December 20.

Data SourcesThis report illustrates the typical weather in Tegsh, based on a statistical analysis of historical hourly weather reports and model reconstructions from January 1, 1980 to December 31, 2016. Tegsh is further than 200 kilometers from the nearest reliable weather station, so the weather-related data on this page were taken entirely from NASA's MERRA-2 satellite-era reanalysis . 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. The temperature and dew point estimates are corrected for the difference between the reference elevation of the MERRA-2 grid cell and the elevation of Tegsh, according to the International Standard Atmosphere . All 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. 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.
