The year, day by day
Summer here tops out rather than builds: the warmest normal high is 60°F around June 28, short of 90°F on every date, while 275 dates carry a normal low at or below freezing, the coldest -18°F near January 6.
The freezing stretch
The normal low stays at or below 32°F into May 29, then returns to freezing around August 29, covering 275 dates in all.
Derived from the normal daily minimum. This is a different measure from the 50%-probability frost dates shown elsewhere on this page, which come from NOAA’s frost product.
The widest day
April 6 carries the biggest normal gap between afternoon and dawn, 26°F between the normal high and the normal low.

Data-derived climate profile
How Toolik Lake's climate pattern fits together
heating led · high swing
Winter and seasonal range jointly define this record. Toolik Lake logs 16,801 heating degree days, more than twice its 0 cooling total, while the typical coldest-to-warmest-month gap reaches 55.5°F. The annual mean therefore compresses two materially different seasons.
A frost-free growing-season length is not available for Toolik Lake. That missing field is kept separate from the observed temperature and precipitation record rather than filled from a regional estimate.
Toolik Lake's calendar has a pronounced split: July and December mark the typical warm and cold ends of the calendar, with 55.5°F between them. The annual average is 19°F. That average is context, while the monthly highs, lows, and precipitation totals describe the lived parts of the year.
A moisture-range label is withheld because Toolik Lake's annual precipitation total is unavailable. Monthly source values remain visible where NOAA provides them, and no annual amount is reconstructed from incomplete data.
These labels group NOAA 1991-2020 normals from Toolik Lake's primary station, so the winter figures are a thirty-year average and not a floor: a single hard season can run well below them. Treat each band as a descriptive range for Toolik Lake, not an official NOAA class or a year-ahead forecast.

Data Sources
Data source: NOAA U.S. Climate Normals v1.0.1 (1991-2020). All figures on this page are from Toolik Lake's primary station: TOOLIK LAKE 5 ENE (USW00096409). For informational purposes only.
Place identity: U.S. Census Bureau 2024 Gazetteer places. The conservative exact name-and-state crosswalk finds no Census place match, so PlainClimate treats this as a station-mapped location and does not claim it is a municipality. No exact Gazetteer row for Toolik Lake; facility counts that depend on place identity are therefore an upper bound, not a municipal census.
On this page every temperature, precipitation, and derived score for Toolik Lake comes from its primary NOAA station record. No figure on this page is typed in by an editor - each value is rendered from NOAA 1991-2020 U.S. Climate Normals.
