Slight warming is expected on Memorial Day in some parts of San Diego County, with a mild week ahead, forecasters said.

Coastal San Diego will see mostly cloudy conditions throughout the week, with highs ranging from the upper 60s to low-70s. The mountains and valleys will see a mix of partly cloudy and some windy conditions, with highs in the mid-70s.

The deserts will see mostly clear and sunny conditions, with some mild winds and highs possibly hitting the triple digits by Monday, according to the National Weather Service.

Downtown San Diego on Memorial Day will see cloudy conditions in the morning, then gradually become mostly sunny, with a high near 69 and gusts as high as 20 mph.

Monday’s San Diego surf forecast includes a moderate-risk rip current, with surf height from 2 to 4 feet, a mixed west swell from 280 degrees and south swell from 210 degrees.

West to northwest winds around 20 knots will occur in the outer coastal waters from 30 to 60 nautical mile each afternoon and evening through Wednesday.

“A short wave ridge is expected over the area by next Saturday which could bring additional minor warming and a continued shallow marine layer,” the NWS said.
