With warm temperatures, little humidity, high clouds, nice beach conditions and a low fire threat, the Bay Area geared up Friday for its second straight weekend of weather that most places dream of having.

“Good weather to sleep in, comfortable in the afternoons,” National Weather Service meteorologist Karleisa Rogacheski said of weather that has marked the region for more than a week. “Perfect really, or close to it.”
The only areas where it may get slightly uncomfortable are far inland. Concord and Livermore may inch into the low 90s on Sunday, but the hotter spots in the rest of the region won’t escape the upper 80s, according to the weather service. San Jose is expected to max at 87, while areas near water — Oakland, San Mateo, San Francisco — won’t get past the low 70s.
The high temperatures Friday were expected to be on average about 4-6 degrees cooler than Thursday’s high temps, but they will begin creeping up again slowly starting Saturday.
“Generally, there’s a slight cooldown that will be moderate through Sunday and Monday,” Rogacheski said. “Then the temperatures might build by the end of next week. It’s really dependent on the upper-level low (pressure). That will play with how deep the marine layer will get every night.”

The marine layer — the region’s natural air conditioning — is expected to remain thick through the weekend, with the possibility of coastal fog and drizzle. The thicker it remains, the more widespread the moderate temperatures persist.
Save for a heat wave earlier this month, that marine layer has stayed steadfastly thick.
“The high pressure has been off to the east,” Rogacheski said. “More of less, it’s been there most of the summer. We’re caught between that high pressure and the upper-level low pressure trough. That’s what brings about that perfect California weather.”
Beaches are expected to be relatively safe this weekend. The weather service said waves are at normal levels with swells that caused hazards earlier this summer no longer in play.
