A year in Brisbane at a glance
Each month’s typical high and low, and what it brings.
What stands out about Brisbane’s climate
Compared with towns across the U.S., with Brisbane’s place in California beside it.
What a year in Brisbane feels like
Typical highs and lows by season and by month, from NOAA’s 30-year normals.
Frost is rare
Frost and day counts come from NOAA’s station at San Francisco International Airport, 4 miles from the town’s center, at about the same height.
The 2023 USDA map puts Brisbane’s center in zone 10b: the coldest night of a typical winter, averaged over 1991–2020, reaches about 36°. Plant labels use the zone; frost dates tell you when to plant.
90° days by month
Average days at 90° or more
About 24 inches of rain a year
December is the wettest month and July the driest. Rain falls on about 69 days a year. Snow is rare: about 0.0" in a normal year at Pacifica 4 Sse, CA, so most winters see none.

Heating and cooling a home in Brisbane
93% of the work is heating, so the furnace matters far more than the air conditioner. Months averaging under 55° run from December through March.
Degree days add up how far each day’s average falls below (heating) or rises above (cooling) 65° over a year. NOAA normals at San Francisco International Airport.
Living with Brisbane’s climate
What the numbers mean for a garden, a free afternoon and a bad-weather day.
Zone 10b. Frost comes about 1 winter in 9, so tender plants can often stay out through winter.
Months with highs of 62–84° and lows of 40° or more: March, April, May, June, July, August, September, October and November. 5.0 miles of trails are waiting.
Parks & trails →Of the yearly building losses FEMA expects in Brisbane from natural hazards, earthquakes are the largest share (79%). Normals are averages; the hazards page covers the extremes.

Climates most like Brisbane’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 |
|---|---|---|---|---|
| Brisbane, CA | 45° | 70° | 24" | 0.0" |
| Port Angeles, WA | 37° | 69° | 28" | 0.4" |
| Makawao, HI | 53° | 75° | 23" | 0.0" |
| Cedar Mill, OR | 36° | 81° | 39" | 3.6" |
| Nantucket, MA | 26° | 76° | 44" | 25" |
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 Brisbane averaged 1.6° warmer than the 1900s. The biggest change is in January (+2.4°).
A bigger shift than in 66% 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.
How Brisbane compares
Against 12,954 U.S. towns of 2,500 or more (one per 5 km climate cell), with Brisbane’s place among California’s.

How much a month can swing
A normal is an average. November swings the most: from 1991 to 2020 its average ranged from 49° to 59°. June is the most reliable, staying within 5°.
