Back To Local Summer

High pressure builds in from the west Sunday into Monday. Compression of the marine layer will cut back on coastal clouds and allow for warmer temperatures near the coast. The initial impact will be an increase in coastal fog Sunday morning, however! Temperatures will peak for most areas on Monday, though the Monterey/Seaside area may be a little warmer Tuesday as surface winds switch to the south. Low clouds will then thicken with cooler weather for all on Wednesday.

AIR QUALITY: Good to Moderate

Overnight: Low clouds and fog for the coast and nearby valleys. Low sin the 50s on the coast and in the valleys & hills. A higher valleys in the south/east will dip into the 40s.

Sunday: Coastal fog early, then sunny and warmer with coastal highs in the mid 60s to mid 70s and upper 70s to upper 90s inland. Windy up valleys late in the day.

Monday: Patchy AM fog right along the coast, otherwise mostly sunny with a few high clouds passing through. Warmer, with coastal highs in the 70s to mid 80s and mid 80s to around 102ºF inland. Windy up valleys late in the day.

Extended: Temperatures will cool a bit on Tuesday and then significantly on Wednesday as a lower pressure aloft allows for a deeper marine layer. We’ll see some balance late in the week with more seasonable weather.
