Man I hate La Nina Summers, dealing with the constant gloom every morning is so annoying. 

 

I wish we could get a strong El Nino to form and have a repeat of Summer 2015 again, that was the best Summer ever with the unusually warm sst creating very warm overnight temps and consistent tropical/monsoonal moisture lasted all the way until October that year.

I get what you are saying about gloom in the summer... but 2015 was a pretty extreme summer in the West.    

 

This is not exactly a Nina summer either.   Its closer to neutral and the water off the CA coast is not that cold.

Compare that to a summer like 2011:

I headed out to a remote section of the Santa Margarita River near Camp Pendleton today. It was hot and dry out there, but there was still flowing water in the river (which was too large in file size for this forum so I had to downsize it):

Northwest winds cause upwelling, below normal sea surface temperatures, and endless gloom at the beaches.

 

Catalina is probably still closed down due to covid and the ocean temperatures may be approaching those of winter.

 

 

Live view from Catalina... looks horrible.    B)

Good heavens! No wonder it’s so gloomy here. What changed? This is looking more and more like 2010 and it’s really getting to me. It hasn’t cracked 70 for almost a week here in Manhattan Beach and I’m starting to get seasonal affective-like symptoms.

 

Lurked here for a while but decided to sign up today. I’m an armchair weather geek and I came here wondering what the hell turned our marine layer all the way up to ludicrous speed. What’s causing the NW winds to be so persistent this year? Feels more like May than almost August.

Highs today: 68 in Newport Beach, 86 in Fullerton, 100 in San Bernardino, 112 in Palm Springs. 112 is actually not that unusual for Palm Springs this time of year. Far from record breaking heat.

As a heat lover, numbers like this make me jealous of inlanders. Unfortunately I’m in about the worst possible place you can be if you prefer heat: Manhattan Beach. 61 and foggy here...eugh.

Bay Area forecast discussion this morning

 

Will it actually rain for the beginning of August, or are they just referring to the usual marine layer drizzle?

 

 

At the synoptic scale, as previously alluded to, the San Francisco
Bay Area and Central Coast regions are currently positioned in
the southwesterly buffer region between a 555dm 500mb low pressure
system off the PacNW to the NW and a 597dm 500mb high pressure ridge
centered over Arizona to the SE. These two systems and their
descendants will take turns nudging into the vicinity of the
forecast area over the next week in an attempt to challenge the
"stratus quo", resulting first in a minor to locally moderate
warming/drying trends for the interior (now through the weekend),
then a shift towards a cooler, wetter, breezier regime mid to late
next week as the low pressure digs into the vicinity.
Breezy
northerly winds will develop along shore and throughout some of the
interior late this weekend into this weekend as the northerly
gradient strengthens in response to further subtle shifts in the
high-low synoptic scale dichotomy.

Clearing out. Inversion must be mega strong; I could see steam from the nearby refinery doing a “loop-de-loop” as it rose and then sank.

I noticed something similar here on Monday when it was in the mid 90s.

 

Someone was having a BBQ on the other side of the lake and instead of the smoke rising vertically like normal it was spreading out horizontally across the lake.

Looks like we’ll be stuck behind the “Sepulveda wall” for the fifth consecutive day at this rate. Sea breeze kicking in and the steam is swiftly following it now.

 

When it comes to warming trends in Manhattan Beach particularly, I’m skeptical. Forecast high is 73. I’ll believe it when I see it. Our microclimate seems unusually exposed even for the coast. Sometimes we’re even cooler than the Santa Monica Pier. I’ve seen it countless times where it clears out literally everywhere else except a mile-wide stretch of the coastal strip from LAX to PV, roughly paralleling Sepulveda Boulevard, so I call it the Sepulveda Wall.

Gross. We still have hope for the high to do its thing in August and bring an end to the Bummer Summer Deluxe.

 

It’s certainly weird. It feels like 2010 at the coast but unlike 2010, temperatures aren’t below normal away from it. Instead it feels like late spring during a weak heatwave, with insanely pronounced microclimates. MB is looking like a mere 64 for a high. Meanwhile it’s set to break 90 in Anaheim. Starting to remind me more of the Bay Area than normal mid-summer conditions for LA.
