We know the question on your mind, San Diegans — when’s it going to cool down? Thanks to the National Oceanic and Atmospheric Administration’s (NOAA) Climate Prediction Center, we know what temperatures and precipitation trends to expect in our city for September, October, and November.

While exact weather conditions typically can’t be predicted more than a week in advance, here’s a seasonal outlook to help you prepare for what fall will bring.

Reminder: The first day of fall is on Sept. 22, 2024.

Temperature
This fall, San Diego will experience typical temps — which us locals know can mean it'll still be pretty toasty out there. In broader San Diego County, some areas will see temps leaning 33-40% above normal.

Precipitation
Think fewer showers. After a real rainy start to 2024, SD is expected to get 33-40% below normal rainfall this autumn.

Drought
NOAA is forecasting drought conditions will be kept at bay this fall. January-May 2024 made for the 27th wettest year to date in San Diego County over the past 130 years. July 2024 was the driest July on record.

Dancin’ in September
San Diegans know temperatures are still warm, averaging a high of 76.6° with a relative humidity of 68%. Ocean temps are nice, too, averaging 66.7° — the second warmest month for the sea in SD as the tourists leave and "locals summer" begins. The UV index remains high, so use sun protection and limit your exposure to those rays.

Oh hay, October
San Diego averages a high temperature of 73.2° in October, and rain falls for ~3.4 days. The sea temps take a dip, averaging 65.1° — but beach days (maybe sans swimming) are still on the horizon along the coast with the most.

Nice November
Flannel and flip-flops, anyone? The average daytime high is a pleasant 68.5° and a cool 57.4° at night — perfect hiking weather. November is the least humid month with 59% relative humidity, and it rains for an average of 5.1 days.
