Wasilla, Alaska
The week’s forecast, measured against two yardsticks: the “normal” your weather app still uses — a 1991–2020 average centered on 2005 — and the climate-adjusted normal, which here runs +0.7°F warmer. Same NOAA data. No pretending.

1991 called. It wants its climate baseline back.

The “normal” temperature in every weather app is a 30-year average (1991–2020) — a number centered on mid-2005, two decades out of date in a warming climate. The Climate-Adjusted Normal takes NOAA’s official normal and advances it to the present using this county’s own measured warming trend.
It isn’t a forecast — it’s a more honest yardstick for what “normal” means now. Read why Nowmal exists →

About this data
The forecast is the National Weather Service’s, for Wasilla itself. Normals and the warming trend are computed at county level (Matanuska-Susitna Borough) from NOAA’s homogenized climate record, because climate trends vary smoothly — nearby towns warm at statistically indistinguishable rates. Method details on the methodology page.
