Over the course of August at Resolute Bay Airport, the chance of a day with only rain decreases from 19% to 7%, the chance of a day with mixed snow and rain remains an essentially constant 3% throughout, and the chance of a day with only snow increases from 0% to 4%. RainfallTo show variation within the month and not just the monthly total, we show the rainfall accumulated over a sliding 31-day period centered around each day. The average sliding 31-day rainfall during August at Resolute Bay Airport is gradually decreasing, starting the month at 1.0 inches, when it rarely exceeds 2.0 inches or falls below 0.3 inches, and ending the month at 0.6 inches, when it rarely exceeds 1.5 inches or falls below 0.1 inches. The highest average 31-day accumulation is 1.0 inches on August 3. 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 August at Resolute Bay Airport is increasing, starting the month at 0.6 inches, when it rarely exceeds 2.1 inches or falls below -0.0 inches, and ending the month at 2.7 inches, when it rarely exceeds 7.4 inches. SunDue to its extreme latitude, Resolute Bay Airport 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 summer at Resolute Bay Airport during 2024, the Sun is continuously above the horizon for 3.5 months, rising at 1:46 AM on April 28, and not setting again until 12:41 AM on August 14. As such, August begins the month in polar day, which ends before the month is out. The shortest day of the month is August 31, with 16 hours, 47 minutes of daylight. The earliest sunrise of the month at Resolute Bay Airport is 2:08 AM on August 14 and the latest sunrise is 2 hours, 45 minutes later at 4:53 AM on August 31. The latest sunset is 12:41 AM on August 13 and the earliest sunset is 3 hours, 1 minute earlier at 9:41 PM on August 31. Daylight saving time is observed at Resolute Bay Airport during 2024, but it neither starts nor ends during August, so the entire month is in standard 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 August 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 Resolute Bay Airport is essentially constant during August, 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 Resolute Bay Airport is gradually increasing during August, increasing from 10.6 miles per hour to 11.2 miles per hour over the course of the month. For reference, on January 28, the windiest day of the year, the daily average wind speed is 12.1 miles per hour, while on June 21, the calmest day of the year, the daily average wind speed is 9.7 miles per hour. The hourly average wind direction at Resolute Bay Airport throughout August is predominantly from the north, with a peak proportion of 40% on August 31. Water TemperatureResolute Bay Airport 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 Resolute Bay Airport is essentially constant during August, remaining around 33°F throughout. The highest average surface water temperature during August is 33°F on August 8. 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 Resolute Bay Airport typically lasts for 4.1 weeks (29 days), from around June 28 to around July 27, rarely starting before June 9, or ending after August 20. The month of August at Resolute Bay Airport is more likely than not fully outside of the growing season, with the chance that a given day is in the growing season rapidly decreasing from 40% to 2% over the course of the month. 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 Resolute Bay Airport are essentially constant during August, remaining within 1°F of 11°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 Resolute Bay Airport is rapidly decreasing during August, falling by 1.7 kWh, from 4.0 kWh to 2.3 kWh, over the course of the month.

Data SourcesThis report illustrates the typical weather at Resolute Bay Airport, based on a statistical analysis of historical hourly weather reports and model reconstructions from January 1, 1980 to December 31, 2016. Temperature and Dew PointResolute Bay Airport 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. In this case, the only station close and reliable enough to use as a fallback is Resolute. 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.
