For reference, the year's highest daily chance of a wet day is 23% on August 10, and its lowest chance is 3% on December 30. 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 February at Sdr Stroemfjord is gradually increasing, starting the month at 1.6 inches, when it rarely exceeds 4.6 inches or falls below -0.0 inches, and ending the month at 2.1 inches, when it rarely exceeds 6.4 inches or falls below -0.0 inches. SunDue to its extreme latitude, Sdr Stroemfjord experiences polar day (also known as the midnight Sun) during the summer. 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. Neither polar day nor polar night occur during the month of February. Over the course of February at Sdr Stroemfjord, the length of the day is very rapidly increasing. From the start to the end of the month, the length of the day increases by 3 hours, 38 minutes, implying an average daily increase of 7 minutes, 48 seconds, and weekly increase of 54 minutes, 34 seconds. The shortest day of the month is February 1, with 6 hours, 13 minutes of daylight and the longest day is February 29, with 9 hours, 51 minutes of daylight. The latest sunrise of the month at Sdr Stroemfjord is 10:30 AM on February 1 and the earliest sunrise is 1 hour, 50 minutes earlier at 8:40 AM on February 29. The earliest sunset is 4:43 PM on February 1 and the latest sunset is 1 hour, 48 minutes later at 6:31 PM on February 29. Daylight saving time is observed at Sdr Stroemfjord during 2024, but it neither starts nor ends during February, 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 February 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 at Sdr Stroemfjord is essentially constant during February, 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 at Sdr Stroemfjord is decreasing during February, decreasing from 9.4 miles per hour to 8.2 miles per hour over the course of the month. For reference, on December 19, the windiest day of the year, the daily average wind speed is 9.8 miles per hour, while on July 13, the calmest day of the year, the daily average wind speed is 6.0 miles per hour. The hourly average wind direction at Sdr Stroemfjord throughout February is predominantly from the south, with a peak proportion of 62% on February 1. Water TemperatureSdr Stroemfjord 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 at Sdr Stroemfjord is essentially constant during February, remaining around 31°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 at Sdr Stroemfjord typically lasts for 2.6 months (81 days), from around June 1 to around August 22, rarely starting before May 16 or after June 20, and rarely ending before August 1 or after September 8. The month of February at Sdr Stroemfjord 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 at Sdr Stroemfjord are essentially constant during February, remaining around 0°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 at Sdr Stroemfjord is gradually increasing during February, rising by 0.9 kWh, from 0.2 kWh to 1.2 kWh, over the course of the month.

Data SourcesThis report illustrates the typical weather at Sdr Stroemfjord, based on a statistical analysis of historical hourly weather reports and model reconstructions from January 1, 1980 to December 31, 2016. Temperature and Dew PointSdr Stroemfjord has a weather station that reported reliably enough during the analysis period that we have included it in our network. When available, historical temperature and dew point measurements are taken directly from this weather station. These records are obtained from NOAA's Integrated Surface Hourly data set, falling back on ICAO METAR records as required. In the case of missing or erroneous measurements from this station, we fall back on records from nearby stations, adjusted according to typical seasonal and diurnal intra-station differences. For a given day of the year and hour of the day, the fallback station is selected to minimize the prediction error over the years for which there are measurements for both stations. The stations on which we may fall back are Sisimiut /Holsteins and Sisimiut Airport. 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.
