We base the humidity comfort level on the dew point, as it determines whether perspiration will evaporate from the skin, thereby cooling the body. This report illustrates the typical weather in Barrow year round, based on a statistical analysis of historical hourly weather reports and model reconstructions from January 1, 1980 to December 31, 2016.
Definitions 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 percentage of time spent in each cloud cover band, categorized by the percentage of the sky covered by clouds. 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. 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. We draw particular cautious attention to our reliance on the MERRA-2 model-based reconstructions for a number of important data series. All other weather data, including cloud cover, precipitation, wind speed and direction, and solar flux, come from NASA's The figure below shows you a compact characterization of the hourly average temperatures for the quarter of the year centered on January.
All data relating to the Sun's position (e.g., sunrise and sunset) are computed using astronomical formulas from the book, The information on this site is provided as is, without any assurances as to its accuracy or suitability for any purpose. The percentage of time spent at various humidity comfort levels, categorized by dew point. The lowest average 31-day liquid-equivalent accumulation is 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 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. These temperatures are far removed from those records observed in Barrow in the month of january with a maximum record of 36°F in 2017 and a minimum record of -36°F in 2012.
For the purposes of this report, the geographical coordinates of Barrow are 71.291 deg latitude, -156.789 deg longitude, and 3 ft elevation. The daily average water temperature (purple line), with 25th to 75th and 10th to 90th percentile bands. The average daily incident shortwave solar energy in Barrow is For reference, the year's highest daily chance of a wet day is The percentage of days in which various types of precipitation are observed, excluding trace quantities: rain alone, snow alone, and mixed (both rain and snow fell in the same day). The shaded overlays indicate night and civil twilight. Select a month to view Barrow sunrise & sunset times for the next twelve months.
Please note that the station records themselves may additionally have been back-filled using other nearby stations or the MERRA-2 reanalysis. We report snowfall in liquid-equivalent terms. The actual depth of new snowfall is typically between 5 and 10 times the liquid-equivalent amount, assuming the ground is frozen. The thin dotted lines are the corresponding average perceived temperatures. The number of hours during which the Sun is visible (black line). Daylight saving time is observed in Barrow during 2020, but it neither starts nor ends during January, so the entire month is in standard time. At a distance of 1 kilometers from Barrow, 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.
Over the course of the year, the temperature typically varies from -19°F to 47°F and is rarely below -36°F or above 60°F .
