Tasiilaq has a tundra climate.
Cold all year — even summer stays cool. Here's what that means in plain terms.
What this climate feels like
The four things a regular visitor actually wants to know:
Highs near 11°C in July.
Lows near −9°C in January.
About 919 mm of rain a year. Wettest in March.
Overcast skies dominate much of the year.
What "tundra" means
Climate scientists sort every place on Earth into about 30 climate types, based on how hot, cold, wet and dry it is across the year. Tasiilaq's type — tundra — sits in the broad family of polar and high-altitude climates.
Researchers write climate types as a short letter code. Here is what each letter means:
Cities with the same climate as Tasiilaq
A tundra climate (ET) — these recognizable cities share it. If you know one of them, you know roughly what to expect.
Tasiilaq sits near a climate boundary
This city sits right on the line between tundra and the next type along. Different climate maps file it on different sides of that line; the lived weather doesn't change at the line — it's a naming boundary, not a wall.
Has Tasiilaq's climate type changed?
Stable — Tasiilaq's climate has held the same type between the 1971–2000 and 1991–2020 normals. The label is steady; the climate beneath it is still warming.
What this climate means for you
No real agriculture — cool-tolerant grasses, lichens, mosses; greenhouses for tiny short-summer harvests.
Summer (June–August) brings tundra hikes, wildflowers and the midnight sun. Winter is for aurora and dogsledding under extreme cold.
Permafrost, polar night in winter, brief sunlit summers. Heating dominates everything.
Where these numbers come from
The climate type and the month-by-month figures on this page are computed from Tasiilaq's measured 30-year climate normals (1991–2020) — the same official records behind Tasiilaq's main climate page, so the two always agree.
Long-range climate maps measure things slightly differently and can place a city in a neighbouring category. Where they differ, this page uses the measured station record as the climate today.
Methodology & sources
Temperature & precipitation — 1991–2020 normals computed from 28 years of daily observations at Tasiilaq, a weather station, about 2 km from the city centre. The underlying daily records come from NOAA's global station network.
