Actually in a few more days. SoCal Summer mid way is 9/15. If you go 45 days either way, it starts Aug 1 and ends on Halloween. Then Fall: Nov, Dec, and Jan. Winter starts in Feb. You can be sure you will be chilly here in Feb. Sometimes it's a short Winter. Sometimes it's a long Fall.
Whatever the year's weather, I bet it's 2-3 months behind yours if you don't live here. And by
here I don't mean all of the Southwest. NM gets 4 seasons and
AFAIK they are closer to the calendar seasons.
Anyway, it's been hot and humid for a few days touching 90º here 8 miles from the Pacific and the inland areas have been closer to 100 a few days, but always 90 something. Day after day.
I see looking at the weather map that TX is similar right now, but Winter sneaks up a little sooner? A lot more rain in TX vs. SoCal for the next 2-3 months. We might see some rain this year. El Niño conditions expected.
I see Las Vegas is hot but will cool down sooner in mid Oct than SoCal.
What's your report and outlook?
