Weather extremes
How extreme does Washington's weather get?
The hottest, coldest, wettest and snowiest days Washington has recorded — the outer limits of what its weather can do, and how far they sit beyond a normal day.
The four kinds of extreme
The hottest, coldest, wettest and snowiest single days Washington has recorded — each shown against what a normal day that time of year looks like.
That is about 16°F hotter than a normal July afternoon in Washington (typical high near 99°F).
The three most extreme on record
About 15°F colder than a normal January night in Washington (typical low near 31°F).
The three most extreme on record
More rain in a single day than Washington usually gets in the whole month of September (typical September total about 0.2 in).

How hot and cold it gets, month by month
The shaded band is the normal range of daily temperatures for each month. The dots show the most extreme it has ever been — so you can see how far beyond a normal day the records really sit.
Washington's record heat sits well above even a hot day for the season — July's 114°F is about 16°F beyond a normal hot afternoon. Its record cold is just as far below a normal winter night — the dots mark how rare each extreme really is.

Methodology & sources
Temperature — modelled for this location from ERA5-Land reanalysis, a ~9 km global grid, because no long-record weather station is close enough to use.
Precipitation — 1991–2020 normals computed from 3 years of daily observations at ST George Muni AP, a weather station, about 9 km from the city centre. The underlying daily records come from NOAA's global station network.
