NWS San Diego Forecast Discussion – Synopsis
Issued 1221 PM PST Fri Nov 13 2026
Well-below-normal temperatures for the entirety of the forecast period. Additional precipitation and stronger winds expected through Saturday, with hazards for both the marine waters and the beaches prevailing through the weekend. Additional wind and rain/snow possible with another system Monday/Tuesday. A third system late next week may bring similar impacts but with lower confidence.
Covers extreme southwestern California, including Orange, San Diego, western Riverside and southwestern San Bernardino counties.
Gusty south and west winds this weekend, especially Friday evening through Saturday morning. During this time, gusts 25-45 mph over the mountains and deserts, and gusts 45-55 mph through the passes. Over the waters, expect gusts up to 25 knots. Winds decrease late Saturday through early Monday, then increase again late Monday into Tuesday to likely similar levels.
These winds, in combination with a large northwest swell, will bring choppy, steep seas to the region for much of the weekend into parts of next week.

How to Read This
Score
0–100, based on the wet-bulb depression — how much cooler the air could get versus the actual outside temperature. Drier air means more room to cool, so a bigger gap scores higher.
Wet-Bulb Depression
The gap between the outside (dry-bulb) temperature and the wet-bulb temperature — the coolest evaporation alone could get the air. A bigger gap means drier air and more room for the cooler to work with.
Estimated(Est.) Output
The approximate temperature of the air coming out of the cooler, estimated by cooling the outside temperature most of the way toward the wet-bulb temperature.
Efficiency
These numbers assume 80% saturation efficiency — typical for a well-maintained direct (single-stage) evaporative cooler.
Lower dew point + higher temp = better cooling
(This guide generally will work for misting systems also)
