Average Temperature In Fairbanks Alaska In September - ANCHORAGE, Alaska (KTUU) - You'll often hear meteorologists say temperatures will be above or below normal. By Tuesday, this "normal" had changed.
Climate averages are observations taken from about 15,000 weather stations across the country over a 30-year period. Every ten years, the National Oceanic and Atmospheric Administration updates this dataset. The new data released Tuesday now uses observations from 1991 to 2020.
Average Temperature In Fairbanks Alaska In September
Overall, the state is warmer than the previous average period from 1981 to 2010. Western and northern Alaska in particular are getting warmer. In Anchorage, for example, both the average high and low temperatures on May 4 rose by a full degree.
Top Reasons To See Alaska In September
The strongest warming is mainly concentrated in autumn and late winter. October, November, and February in Anchorage warm about 1.5 degrees.
Not every month shows a warming trend. December and January show slightly cooler temperatures in the southern part of the state. This is probably due to very warm January years in the 1980s, which are now outside the climatic normal. Some of the coldest Januarys on record for Anchorage occurred in the 2010s, and are now included in the new data set.
An interesting fact from the new averages is that the climate classification for Fairbanks has changed. It is classified as "Subsidiary". Now it is a "hot continental summer climate". Because now the average temperature in May exceeds 50 degrees.
There is more snow in the anchorage now, but it is concentrating for a short time. Snowfall in Anchorage is around 3.5 inches for the season. October snowfall is less than 2 inches. This means that extra snow, which is now considered normal, will be compressed into several months.
Things To Do In Fairbanks, Ak
Climate averages are used for a variety of purposes, such as calculating the growing season or how much energy might be needed in a typical month for heating or cooling. The data is also used for basic travel information, such as how cold it will be for a person in Fairbanks in January. The answer is that the average high for Fairbanks in January is less than 1 degree and the average low is less than 17 degrees. September, the first month of fall, is still the coolest month in Fairbanks, Alaska, with average temperatures between 52.5°F and 36.3°F. As temperatures begin in September, there is a drop in the average high temperature, dropping from a pleasant 63.9°F to a brisk 52.5°F in August. Temperatures drop to an average of 36.3°F during September. Humidity The average relative humidity in September is 75%. Precipitation It rains 13.1 days in September in Fairbanks, with a regular precipitation total of 1.26". Fairbanks, Alaska has 100.5 days of precipitation throughout the year and 10.87 of the precipitation totals. Snow falls from January to May, snows from August to December. months. In Fairbanks, in September, it snows 1.6 days and regularly accumulates up to 0.79". Over the year in Fairbanks, it snows 74.3 days and accumulates 24.49" of snow. Average daylight in Fairbanks in September is 13 hours 0 minutes.
On the first day of the month, sunrise is at 6:31 am and sunset is at 9:10 pm. On the last day of September, sunrise is 7:58 AM and sunset is 7:23 PM AKDT. Sunshine In Fairbanks, the average sunshine in September is 7.4 hours. UV Index In September, the average daily maximum UV index is 2. A UV index reading of 2 and below represents a low health risk to the average person from exposure to the sun's UV radiation.
Although most people can withstand up to an hour in the sun without burning, children always need sun protection. The best time to avoid the sun's harmful UV rays is midday, when it is strongest. Prioritize a wide-brimmed hat for full sun protection for the face, neck, eyes and ears. Get ready! Snow reflection can double the intensity of the sun's UV rays.
In September, the sunrise on the first day of the month is 06.31 and the sunset is 21.10. On the last day of the month, in Fairbanks, Alaska, sunrise is 7:58 AM and sunset is 7:23 PM AKDT.
Alaska Is Off To A Frigid Start In 2020 After Record Warm 2019
The average daily maximum UV index in September in Fairbanks, Alaska is 2. A UV index estimate of 2 and below represents a minimal health hazard from unprotected exposure to UV radiation. Temperatures in Alaska have increased by approx. 3°F since 1925 but with large multidecadal variations. Most of the warming has occurred in winter and spring. Under a high emissions pathway, historically unprecedented warming is projected this century.
Annual average precipitation across Alaska is projected to increase by 10% or more by the middle of this century under a high emissions pathway.
The extent and thickness of Arctic sea ice in late summer has decreased significantly in recent decades. Climate models estimate that Arctic waters will be virtually ice-free in late summer before 2050.
Time series of observed, modeled historical, and projected temperature changes (in degrees Fahrenheit) from 1901 to 2100 for Alaska, as described in the caption. Y-axis values range from minus 6.9 to 22.9 degrees. The observed annual temperature change from 1925 to 2020 shows a variation and ranges from minus 4.0 to 6.3 degrees. By the end of the century, warming projections increased from 2.9 to 12.9 degrees under the lower emission trajectory and from 9.8 to 21.6 degrees under the upper trajectory.
Despite Variations In Temperature And Precipitation, This Fall Is Average For Fairbanks
Figure 1: Observed and projected changes in near-surface air temperature for Alaska (relative to the 1925–1960 mean). Observed data are for 1925–2020, and historical period model simulations are shown for 1901–2005. Projected changes for 2006-2100 are from global climate models for two possible futures: one in which greenhouse gas emissions continue to increase (higher emissions) and another in which greenhouse gas emissions increase at a slower rate (lower emissions). Temperatures in Alaska (orange line) have increased by about 3°F since 1925, but with large multidecadal variations. Shaded models show the annual temperature range from the set. Observed temperatures are generally within the range of modeled historical simulations (grey shading). Historically unprecedented warming is predicted this century. Less warming is expected under a low-emissions future (the coldest end-of-century projections are about 2 °F warmer than the historical average; green shading) and under a higher-emissions future (the warmest year is about 15 °F warmer than the warmest year on record); red shade).

Alaska's large area and geographic variation lead to a variety of climates. Four main factors influence the state's climate: its northern latitudes straddle the Arctic Circle; its wide elevation range, from sea level to the highest peak in the United States; regional variations near the sea; and the seasonal extent of sea ice along its western and northern borders. Annual mean temperatures (1991–2020 average) range from 13° to 20°F in the Arctic north of the Brooks Range, where moderate maritime influences are stronger (°F) to mid-40s in the south (Figure 2 )); The coldest long-term recording centers are near the Arctic Ocean north of 70°N latitude, with annual mean temperatures below 15°F. The largest seasonal variations in temperature occur in the interior of the state, with average summer temperatures in the high 60s (F°) and average winter lows of 15° to 25°F below zero. The hottest temperature ever recorded in Alaska was 100°F at Fort Yukon, inland (June 27, 1915), and the coldest was -80°F at Prospect Creek, inland (January 23, 1971).

Below are the temperature ranges for reporting stations in Alaska's five regions: 12 to 30 degrees for the northern regions, including 14 degrees for Utqiagvik and 28 degrees for Nome; For the interior, 20 to 35 degrees, including 28 degrees for Fairbanks; For South Central, 30 to 45 degrees including 38 degrees for anchor; For the Southeast, a high of 35 to 45 degrees, including 40 degrees for June; and for the Southwest, 30 to 40 degrees, including 31 degrees for Bethel. The lowest temperatures occur farther north along the Chuchee and Beaufort beaches, while the highest temperatures occur southeast near Ketchikan.

Alaska's temperature climate varies greatly. It was moderately warm from the 1920s to the 1940s, and cooler from the late 1940s to the 1970s.
