December Weather in Clyde River CanadaDaily high temperatures decrease by 10°F, from 2°F to -8°F, rarely falling below -21°F or exceeding 15°F. Daily low temperatures decrease by 10°F, from -8°F to -18°F, rarely falling below -32°F or exceeding 5°F. For reference, on July 22, the hottest day of the year, temperatures in Clyde River typically range from 37°F to 47°F, while on February 25, the coldest day of the year, they range from -23°F to -13°F. The figure below shows you a compact characterization of the hourly average temperatures for the quarter of the year centered on December. 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. Kropotkin, Russia (3,527 miles away); Palatka, Russia (3,216 miles); and McMurdo Station, Antarctica (11,346 miles) are the far-away foreign places with temperatures most similar to Clyde River (view comparison). CloudsThe month of December in Clyde River experiences gradually increasing cloud cover, with the percentage of time that the sky is overcast or mostly cloudy increasing from 81% to 85%. The clearest day of the month is December 1, with clear, mostly clear, or partly cloudy conditions 19% of the time. For reference, on January 26, the cloudiest day of the year, the chance of overcast or mostly cloudy conditions is 88%, while on June 1, the clearest day of the year, the chance of clear, mostly clear, or partly cloudy skies is 45%. PrecipitationA wet day is one with at least 0.04 inches of liquid or liquid-equivalent precipitation. In Clyde River, the chance of a wet day over the course of December is gradually decreasing, starting the month at 9% and ending it at 6%. For reference, the year's highest daily chance of a wet day is 23% on August 1, and its lowest chance is 3% on February 16. 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 December in Clyde River is decreasing, starting the month at 5.2 inches, when it rarely exceeds 12.3 inches, and ending the month at 3.4 inches, when it rarely exceeds 9.5 inches. SunDue to its extreme latitude, Clyde River experiences polar day (also known as the midnight Sun) during the summer and polar night during the winter. These are periods of time in which the sun is continuously above or below the horizon for more than one day. The precise start and end dates of polar day and night vary from year to year and depend on the precise location and elevation of the observer, and the local topography. In the winter in Clyde River during 2024, the Sun is continuously below the horizon for 1.9 months, setting at 11:30 AM on November 22, and not rising again until 11:37 AM on January 19. As such, the sun is continuously below the horizon for the entire month of December. Daylight saving time is observed in Clyde River during 2024, but it neither starts nor ends during December, so the entire month is in daylight saving time. 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 December 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 Clyde River is essentially constant during December, 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 Clyde River is gradually decreasing during December, decreasing from 9.5 miles per hour to 8.9 miles per hour over the course of the month. For reference, on October 9, the windiest day of the year, the daily average wind speed is 10.2 miles per hour, while on July 12, the calmest day of the year, the daily average wind speed is 6.3 miles per hour. The hourly average wind direction in Clyde River throughout December is predominantly from the west, with a peak proportion of 42% on December 7. Water TemperatureClyde River is located near a large body of water (e.g., ocean, sea, or large lake). This section reports on the wide-area average surface temperature of that water. The average surface water temperature in Clyde River is essentially constant during December, remaining around 29°F throughout. 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 Clyde River typically lasts for 1.0 months (31 days), from around July 17 to around August 17, rarely starting before June 21, or ending after September 15. The month of December in Clyde River 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 Clyde River are essentially constant during December, remaining around 23°F throughout. 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 Clyde River is essentially constant during December, remaining around 0.0 kWh throughout. The lowest average daily incident shortwave solar energy during December is -0.0 kWh on December 19.

Data SourcesThis report illustrates the typical weather in Clyde River, 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, Clyde River Climate, in our network suitable to be used as a proxy for the historical temperature and dew point records of Clyde River. At a distance of 3 kilometers from Clyde River, 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 Clyde River 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.
