Issued 234 AM PST Sun Nov 8 2026
Weak to moderate Santa Ana winds will continue today. High temperatures 5-15 degrees above normal for the coastal areas and valleys today. Winds weaken into next week as high pressure moves into the area, keeping temperatures above normal. Gradual cooling with a 15-25% chance of precipitation late in the week.
Covers extreme southwestern California, including Orange, San Diego, western Riverside and southwestern San Bernardino counties.
Weak to locally moderate Santa Ana winds are expected this weekend. Wind gusts will generally be 15-30 mph within inland valleys. Top localized gusts 35-50 mph can be expected in foothills.

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)
