A notable exception? The entire California coastline, where temps peak sometime between late Aug and early Oct. Why? Although sun's lower in the sky & incoming radiation is decreasing, cooling effects of marine layer are greatly dampened in late summer/early fall. #CAwx #CAwater

@Weather_West I always assumed that it is due to the onset of offshore winds with low dew points. Seemed like that in Santa Monica/UCLA, orange Co, and S Oregon coast in my years. My favorite time of year in CA and OR! Not data based, only personal obs.
@Weather_West Can we talk about the crappy color scheme on this map though? This seems like poor science communication. A yellow-red scheme seems to imply temperature extremity, not date
@Weather_West @Weather_West what is the most recent review of climate change impacts on marine layer cooling in coastal California? In a utility wildfire conversation today where this question came up and my knowledge is SUPER out of date. Seems important for evaluating future risk/investment.
@Weather_West The resolution on that map doesn’t show the profoundly hyper local microclimates of coastal Marin County which are still mid-50s (night) to mid-70s (day). Mind blowing. I grew up here yet still can’t believe it.
@Weather_West As a resident of Redondo I always dread late August / mid Oct for this reason
@Weather_West I thought it was because the Central / Sacramento valleys didn't get as hot so the marine layer wasn't pulled onshore.
@Weather_West Its the pattern shift when high pressure builds up East of the bay and the hot/dry wind blows from east to west
