Living with Fremont’s climate
What the numbers mean for a garden, a free afternoon and a bad-weather day.
Zone 10a. Frost comes about 1 winter in 2, so tender plants can often stay out through winter.
Months with highs of 62–84° and lows of 40° or more: February, March, April, May, June, July, August, September, October and November. 66 miles of trails are waiting.
Parks & trails →Of the yearly building losses FEMA expects in Fremont from natural hazards, earthquakes are the largest share (67%); heat waves, cold waves, winter storms and ice storms together are 1%. Normals are averages; the hazards page covers the extremes.

Climates most like Fremont’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 |
|---|---|---|---|---|
| Fremont, CA | 41° | 82° | 15" | 0.0" |
| The Dalles, OR | 31° | 88° | 15" | 5.5" |
| Alpine, TX | 30° | 90° | 15" | 2.2" |
| Sierra Vista Southeast, AZ | 32° | 91° | 15" | 0.7" |
| Makawao, HI | 53° | 75° | 23" | 0.0" |
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 Fremont averaged 1.7° warmer than the 1900s. The biggest change is in January (+2.1°).
A bigger shift than in 75% 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 226,000 people, part of the change is the city itself: pavement and buildings hold heat (the urban heat island).
How Fremont compares
Against 12,954 U.S. towns of 2,500 or more (one per 5 km climate cell), with Fremont’s place among California’s.
