Cloud Cover Categories
A wet day is one with at least 0.04 inches of liquid or liquid-equivalent precipitation. The chance of wet days in Greenland varies throughout the year.
The wetter season lasts 3.5 months, from March 27 to July 9, with a greater than 30% chance of a given day being a wet day. The chance of a wet day peaks at 43% on May 27.
The drier season lasts 8.5 months, from July 9 to March 27. The smallest chance of a wet day is 16% on January 12.
Among wet days, we distinguish between those that experience rain alone, snow alone, or a mixture of the two. Based on this categorization, the most common form of precipitation throughout the year is rain alone, with a peak probability of 43% on May 27.
Daily Chance of Precipitation
To show variation within the months and not just the monthly totals, we show the rainfall accumulated over a sliding 31-day period centered around each day of the year. Greenland experiences significant seasonal variation in monthly rainfall.
Rain falls throughout the year in Greenland. The most rain falls during the 31 days centered around May 13, with an average total accumulation of 4.9 inches.
The least rain falls around January 23, with an average total accumulation of 1.8 inches.
Average Monthly Rainfall
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. Colder, drier snow tends to be on the higher end of that range and warmer, wetter snow on the lower end.
As with rainfall, we consider the snowfall accumulated over a sliding 31-day period centered around each day of the year. Greenland experiences some seasonal variation in monthly liquid-equivalent snowfall.
The snowy period of the year lasts for 3.8 months, from November 25 to March 19, with a sliding 31-day liquid-equivalent snowfall of at least 0.1 inches. The most snow falls during the 31 days centered around January 29, with an average total liquid-equivalent accumulation of 0.3 inches.
The snowless period of the year lasts for 8.2 months, from March 19 to November 25. The least snow falls around July 31, with an average total liquid-equivalent accumulation of 0.0 inches.
Average Liquid-Equivalent Monthly Snowfall

Best Time of Year to Visit
To characterize how pleasant the weather is in Greenland throughout the year, we compute two travel scores.
The tourism score favors clear, rainless days with perceived temperatures between 65°F and 80°F. Based on this score, the best time of year to visit Greenland for general outdoor tourist activities is from mid May to late September, with a peak score in the last week of August.
The beach/pool score favors clear, rainless days with perceived temperatures between 75°F and 90°F. Based on this score, the best time of year to visit Greenland for hot-weather activities is from late June to late August, with a peak score in the third week of July.
For each hour between 8:00 AM and 9:00 PM of each day in the analysis period (1980 to 2016), independent scores are computed for perceived temperature, cloud cover, and total precipitation. Those scores are combined into a single hourly composite score, which is then aggregated into days, averaged over all the years in the analysis period, and smoothed.
Our cloud cover score is 10 for fully clear skies, falling linearly to 9 for mostly clear skies, and to 1 for fully overcast skies.
Our precipitation score, which is based on the three-hour precipitation centered on the hour in question, is 10 for no precipitation, falling linearly to 9 for trace precipitation, and to 0 for 0.04 inches of precipitation or more.
Our tourism temperature score is 0 for perceived temperatures below 50°F, rising linearly to 9 for 65°F, to 10 for 75°F, falling linearly to 9 for 80°F, and to 1 for 90°F or hotter.
Our beach/pool temperature score is 0 for perceived temperatures below 65°F, rising linearly to 9 for 75°F, to 10 for 82°F, falling linearly to 9 for 90°F, and to 1 for 100°F or hotter.
The growing season in Greenland typically lasts for 6.4 months (197 days), from around April 11 to around October 25, rarely starting before March 23 or after April 29, and rarely ending before October 7 or after November 13.

Within 10 miles contains only modest variations in elevation (1,168 feet). Within 50 miles contains very significant variations in elevation (2,238 feet).
The area within 2 miles of Greenland is covered by cropland (57%) and trees (37%), within 10 miles by trees (46%) and cropland (44%), and within 50 miles by trees (59%) and cropland (36%).
This report illustrates the typical weather in Greenland, based on a statistical analysis of historical hourly weather reports and model reconstructions from January 1, 1980 to December 31, 2016.
Temperature and Dew Point
There are 4 weather stations near enough to contribute to our estimation of the temperature and dew point in Greenland.
For each station, the records are corrected for the elevation difference between that station and Greenland according to the International Standard Atmosphere , and by the relative change present in the MERRA-2 satellite-era reanalysis between the two locations.
The estimated value at Greenland is computed as the weighted average of the individual contributions from each station, with weights proportional to the inverse of the distance between Greenland and a given station.
The stations contributing to this reconstruction are: Drake Field (97%, 1.8 kilometers, north); Fort Smith Municipal Airport (1.3%, 76 kilometers, south); Sallisaw Municipal Airport (1.2%, 84 kilometers, southwest); and Russellville Municipal Airport (0.7%, 128 kilometers, southeast).
