Forecast for Sunday evening August 28

Another beautiful day with plenty of sea fog to keep us balmy and even cooler than normal for late August. Look for more patchy fog to push inland through the evening and into early Monday. Overnight lows will be mostly in the 50s with some lingering areas in the 60s. For Monday, scattered fog will slowly withdraw over the coast around noon or early afternoon. Highs will be in the 60s and 70s near the coast. Inland regions should see mostly sunny skies with highs in the 80s and 90s.

Looking ahead, as Monday starts things off quietly, the forecast becomes interesting as a heat wave looms. Our weather computer models all see high pressure building on the west coast and a warming trend as we head into September. However, there are a few quirks and twists that make the prediction less than a slam dunk. The marine layer will likely remain in play for the immediate coastline, making some beaches the perfect place to beat the inland heat. Heat watches are in play across much of the region and could last all Labor Day weekend! We also see a small chance of moderate northerly winds mid week and that could still heat things up for places like the south coast where these winds are creating offshore compressional warming. We will have to watch this very closely for Wednesday and Thursday. Finally, tropical humidity will likely spread north of Baja and possibly produce splashes in Southern California by Labor Day. Chances are slim at the moment, but that could change.

The summer was very mild and that’s because we had a very active onshore flow. Hope he comes back after Labor Day and brings back our good weather!
