"Dew Point Depression"
« on: January 30, 2018, 08:49:29 AM »
Now I understand what dew point depression is. It's that feeling I get when we are in the midst of our "rainy" season, we're at 36% of average rain fall, high temperature records are falling like drought-killed trees, and RH and DP are desert-low... I've got "Dew Point Depression"...

Yeah, we're at 27% of normal and the dew point went above 40°F for the first time in weeks today. I've been having to water my drought-tolerant California native plants for lack of rain. They "think" my yard has seen about 2/3 normal.

I spoke too soon. The dew point only went above 40°F for about 90 minutes. We're back to 17%RH.

Funny.  I had it last summer when the DPs were in the upper 60s and I could sweat a puddle just standing still.

Guess they call that perspective.

That's Southern California lately. It's either above 60 or below 30. We don't get a middle often any more. It's interesting how much the climate has changed here since I was a child. Summer rain was unheard of then, but it's becoming more regular - as is high humidity in the summer. Each summer over the last decade seems like it was more humid than the last. I guess the prevailing winds used to be more westerly in the summer, and now we get tropical jets from south southwest more often.
