The Santa Ana’s Have Arrived

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!

Hot day. Hot night. We officially hit 97&#176 at John Wayne. The Santa Ana’s were blowing. They are dry winds–katabatic winds. Katabatic winds warm as they sink from higher elevations.

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&#176 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.

  1. I’ve seen the temperature there climb to well over 100 degrees from just 70 when the Santa Ana winds shows up in just a few hours. You will find that your tomatoes will ripen extremely fast when those hot winds appear. Check them out tomorrow and let us know Geoff.

  2. No Fair.. I’m visiting Florida. 5:30 this morning when I went to walk the dog and it was already 77 degrees with a dew point of 73 🙁

    I’m not comfortable.. sigh

  3. Or Geoff could be back in Connecticut. Here at noon Eastern, last week’s fire weather warning is a thing of the past. It’s not even 50 degrees and it’s raining off an on all day. It’s part of the same LOW that spawned the deadly tornadoes down south this week.

  4. First time I set foot in SoCal and went rambling with my transplanted friend, he told me he bet it was 100 out. No way, I said – 85 at the most. He set out to prove it to me – went over to some elderly men sitting on a bench and asked if they knew the temperature. “About 100 when I left the house,” one of them said. I was instructed that because of the lack of humidity I wasn’t feeling the intensity of the heat! And I wasn’t complaining either — I crave that weather where you’re dry before you get out of the shower. And yet when we went to a party a gal I was introduced to felt my face and said “Ohhhhh….you have that beautiful New England skin.” Trade ya right now, my friend…
