When is the best weather to visit Greenland?
Normal highs sit between 65°F and 85°F in June, July, August and September.
That is a measurement, not a recommendation: it counts the months whose normal afternoon high sits between 65°F and 85°F, where a light layer is enough by day.

When is the last frost in Greenland?
In Greenland, the last spring frost (32°F) comes after May 23 in half of years and after June 8 in one year in ten; the first autumn frost comes before October 1 in half of years and before September 14 in one year in ten.

- First autumn frost, half of years before
- October 11 year in 10 before September 14; 9 in 10 before October 16
NOAA puts the median frost-free season at 128 days, and the season without a hard freeze (28°F) at 158 days.
A hard freeze (28°F) comes after May 6 in half of springs and before October 14 in half of autumns.
The USDA's 2023 Plant Hardiness Zone Map puts Greenland in zone 5a in ZIP code 49929, the nearest ZIP area.

How much heating and cooling does Greenland need?
A normal year in Greenland brings 8,641 heating degree days, 61% more than the median U.S. place (5,373), and 159 cooling degree days, 83% fewer than the median (908). Eight months need 300 or more heating degree days, a monthly mean of about 55°F or colder. For gardens and crops, NOAA counts 1,547 growing degree days a year above 50°F.

Questions about Greenland's climate
What is the coldest month in Greenland?
January, with a normal high of 25°F and a normal low of 12°F. The warmest is July (76°F by day, 52°F at night).
Does it snow in Greenland?
Yes. NOAA publishes no 1991-2020 snowfall normal for Greenland's NOAA station; the nearest record that keeps one, Ontonagon (6 miles away), records 178 inches of snow in a normal year.
What is the rainiest month in Greenland?
September, with 3.81 in of precipitation in a normal year; the driest is February with 1.68 in.
What plant hardiness zone is Greenland in?
The USDA's 2023 map puts Greenland in zone 5a in ZIP code 49929, the nearest ZIP area.
How late can frost come in Greenland?
In half of years the last 32°F night comes after May 23; in one year in ten it comes after June 8. Waiting until June 8 leaves about a one-in-ten chance of a later frost.
