Patchy low clouds were gradually eroding across portions of San Diego County early Sunday, but otherwise skies were clear, the National Weather Service said.
A weak offshore flow were expected Sunday into early Monday for the northern areas and several more disturbances were forecast to drop south over the west this coming week, prompting periods of gusty winds, both onshore and offshore.
Seasonally cool weather was expected most days, forecasters said.
"There will also be small chances for some light, marine layer precipitation along and west of the mountains Tuesday and Friday," the NWS said.
High temperatures Sunday along coastal areas were predicted to be 61- 66 degrees with overnight lows of 41-47, the NWS said. Highs in the western valleys will be around 65 and 59-64 near the foothills with overnight lows of 39-44.
Mountain highs were expected to be 54-62 with overnight lows of 33-39. Desert highs will be 73-78 with overnight lows of 45-53.
A small craft advisory was issued from 2 p.m. Sunday to 3 a.m. Monday for waters from San Mateo point to the Mexican border extending 30 to 60 nautical miles out.
Wednesday was forecast to be the warmest day of the week west of the mountains thanks to an offshore flow, but mountains and deserts were expected to remain cool, the NWS said.
