Daily high temperatures decrease by 8°F, from 70°F to 62°F, rarely falling below 52°F or exceeding 79°F. The daily average high (red line) and low (blue line) temperature, with 25th to 75th and 10th to 90th percentile bands. Elevation data comes from the Shuttle Radar Topography Mission (SRTM) , published by NASA's Jet Propulsion Laboratory. The percentage of hours in which the mean wind direction is from each of the four cardinal wind directions, excluding hours in which the mean wind speed is less than. The topography within 2 miles of Fairbanks is essentially flat, with a maximum elevation change of 23 feet and an average elevation above sea level of 444 feet. Although the average daily temperatures throughout Southeast Alaska are in the 60s Fahrenheit in August, extreme highs near 90 and lows below 20 … The climate is relatively cool in that locality in the month of august, but it is endurable when dressing warm. The average hourly temperature, color coded into bands. The shaded overlays indicate night and civil twilight. Home | Privacy & Cookies | Contact | About. It is important to note that evening temperatures in Alaska can still be cool in the summer. The month of August in Fairbanks is more likely than not fully within the growing season, with the chance that a given day is in the growing season rapidly decreasing from 100% to 74% over the course of the month. For reference, on July 2, the hottest day of the year, temperatures in Fairbanks typically range from 54°F to 73°F, while on January 18, the coldest day of the year, they range from -13°F to 2°F. The thin dotted line is the corresponding average liquid-equivalent snowfall. 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. The average daily incident shortwave solar energy in Fairbanks is decreasing during August, falling by 1.4 kWh, from 4.5 kWh to 3.1 kWh, over the course of the month. MERRA-2 Modern-Era Retrospective Analysis. The percentage of time spent in various temperature bands. For reference, on July 15, the muggiest day of the year, there are muggy conditions 0% of the time, while on January 1, the least muggy day of the year, there are muggy conditions 0% of the time. From the start to the end of the month, the length of the day decreases by 3 hours, 26 minutes, implying an average daily decrease of 6 minutes, 52 seconds, and weekly decrease of 48 minutes, 2 seconds.

Precipitation Averages for Alaska in August. The figure below presents a compact representation of key lunar data for August 2020. The figure below shows you a compact characterization of the hourly average temperatures for the quarter of the year centered on August. Within 10 miles is essentially flat (1,801 feet). 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. Within 50 miles contains very significant variations in elevation (4,357 feet). This 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. The vertical gray bars (new Moons) and blue bars (full Moons) indicate key Moon phases. Myths about Alaska’s weather abound so it may surprise you to learn from those of us who live in Alaska, the weather’s just fine! For reference, on January 9, the windiest day of the year, the daily average wind speed is 7.7 miles per hour, while on July 13, the calmest day of the year, the daily average wind speed is 4.6 miles per hour. 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. The average rainfall (solid line) accumulated over the course of a sliding 31-day period centered on the day in question, with 25th to 75th and 10th to 90th percentile bands.

The day, twilights (civil, nautical, and astronomical), and night are indicated by the color bands from yellow to gray. 1-907-277-3000 (local calls), 600 Barrow Street, Suite 200 August is known for the warmest water temperatures of about 57°F. From bottom to top, the black lines are the previous solar midnight, sunrise, solar noon, sunset, and the next solar midnight. From bottom (most yellow) to top (most gray), the color bands indicate: full daylight, twilight (civil, nautical, and astronomical), and full night. 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.
