Death Valley temp "only" 123 today - How's it by you? (Escondido: camp, area)

[RosieSD]

It's a very comfortable 83 degrees at my house east of San Diego this afternoon at 2 pm (pool is 82). We had some fog this morning drifting up over the foothills. Looks like the heat wave is over for us.

Yet, the National Weather Service is reporting it's still over 100 in Sacramento right now, so I guess it is still baking up north. (And in our deserts -- it's 108 in Borrego Springs).

Any explanation on that?

I wonder if it feels warmer in the central valley due to all of the canals, rivers, and agricultural watering. They up the humidity and perhaps that keeps overnight temps a little higher as well. Just guessing.

Also, some of the inland empire gets a bit of marine airflow from the coast, so that keeps things a little cooler in some areas than the central valley or further inland.

Here in San Diego County, it can sometimes be hotter in the higher elevations of the mountains during the summer months than it is in the inland valleys and foothills (where I live). Again, I'm not certain, but I always thought that was because the marine layer gets caught in the foothills, while the heat from the desert pushes up against the other side of the mountains. I could be totally wrong about that though.

There's been five days of temps over 105 in my town. Forecast to be another four days of temps over 100. It's only June, for cripes sake. This is why I hate summer.

It's 72/73 here. This is May weather. Never mind cooled more, more like 71.

And... 77 is a little warmer than usual. Mid 60's to low 70's is more the norm.

112°F today, with little to no wind.

I didn't realize Mars got so hot!!!

It got up to 111 where I live, in the Central Valley.

I guess probably so. Marine air is likely the main driving force of what cools the area particularly at night but sometimes during the day if it's strong enough. It appears the marine breeze can readily reach the interior of SF Bay Area and SoCal than the CV for some reason probably due to the location coast ranges. The ocean breeze effects are actually pretty strong in places like Temecula where it lies in a valley channel where breeze reaches in the afternoon and blows away the daytime heat though for some reason it's effect is less apparent in Escondido compared to surrounding cities until later at night. I find that Humidity is usually lower in Central Valley and desert locations. But the overnights there are very warm even on days daytime highs are not comparably "hot"

Though I would be curious how come the inland empire is quite different in this regard compared to the desert even though the desert is not too far away?

In my experience the mountains are usually pretty cold at night except during extreme heatwaves when the offshore flow brings hot air from the deserts there.

When the onshore flow is strong enough it cool even the CV and the deserts feel the effects. This happened a lot this year with a particularly strong May and June gloom. Possibly driven a lingering La Niña
