What a year in Kent feels like
Typical highs and lows by season and by month, from NOAA’s 30-year normals.
About 233 frost-free days a year
In half of years the last 32° night comes by March 20 and the first by November 10. Frost and day counts come from NOAA’s station at Kent, WA, 2.4 miles from the city’s center point, 320 ft lower.
The 2023 USDA map puts Kent’s center in zone 8b: the coldest night of a typical winter, averaged over 1991–2020, reaches about 20°. Plant labels use the zone; frost dates tell you when to plant.

Heating and cooling a home in Kent
94% of the work is heating, so the furnace matters far more than the air conditioner. Months averaging under 55° run from October through April.
Degree days add up how far each day’s average falls below (heating) or rises above (cooling) 65° over a year. NOAA normals at Kent, WA.
Living with Kent’s climate
What the numbers mean for a garden, a free afternoon and a bad-weather day.
233 frost-free days in zone 8b. The last frost comes by Mar 20 in half of years, so many gardeners wait a week or two past that to set out tomatoes. The first fall frost comes by Nov 10.
Months with highs of 62–84° and lows of 40° or more: May, June, July, August and September. 39 miles of trails are waiting.
Parks & trails →Of the yearly building losses FEMA expects in Kent from natural hazards, earthquakes are the largest share (68%); heat waves, cold waves, winter storms and ice storms together are 1%. Normals are averages; the hazards page covers the extremes.

Climates most like Kent’s, farther away
TownRatings’ own comparison of NOAA 1991–2020 normals, not a NOAA product: places of 5,000+ at least 150 miles away, one per state, closest on January low, July high, precipitation and snow.
| Town | Jan. low | July high | Precip. | Snow |
|---|---|---|---|---|
| Kent, WA | 36° | 77° | 40" | 6.3" |
| Fairfax, CA | 41° | 76° | 38" | 0.0" |
| Silverton, OR | 36° | 81° | 46" | 1.1" |
| Nantucket, MA | 26° | 76° | 44" | 25" |
| Brigantine, NJ | 28° | 83° | 45" | 10" |
Temperatures and rain come from NOAA’s 5 km grid, so each town gets its own value. Snow and frost-free days come from the nearest weather station, so neighbors often share them.
Warmer than it used to be
The last 30 years in Kent averaged 1.0° warmer than the 1900s. The biggest change is in January (+2.4°).
A smaller shift than in 80% of U.S. towns.
Change by month
The two periods overlap (1991–2000 is in both), which makes the gap a little smaller than it would be between separate periods. In a city of 135,000 people, part of the change is the city itself: pavement and buildings hold heat (the urban heat island).
How Kent compares
