Hot day. Hot night. We officially hit 97° at John Wayne. The Santa Ana’s were blowing. They are dry winds–katabatic winds. Katabatic winds warm as they sink from higher elevations.
Other areas get winds like this, the Chinook east of the Rockies for instance, but SoCal has the largest concentration of affected residents.
The dew point stayed in the teens all day with the relative humidity hovering near 5%. Someone posted a photo on Facebook reminding everyone nosebleed season is here!
We didn’t run the a/c. I was very tempted. Maybe tomorrow.
This room, my office, catches afternoon sun. It holds heat longest. The overhead fan is silently spinning. Fans make a big difference, especially here where evaporation needs little prodding.
As moisture on your skin evaporates you feel cooler. In humid climates where evaporation takes place more slowly the same temperature leaves you feeling warmer!
Today’s heat index was actually 5-6° cooler than the air temperature. On the East Coast that’s unheard of.
Santa Ana’s also raise the fire danger.
There are a few more days of this weather coming. Trust me, I’m not complaining.
