San Diego International Airport was reporting clear skies and about 57 degrees early Tuesday, with the city headed for a sunny high near 74. The calm start is a brief pause before a warm-up that sends temperatures into the 80s this weekend, including a projected 83 degrees Saturday and 82 degrees Sunday.
The National Weather Service in San Diego expects Tuesday to stay sunny. A slight chance of light showers is forecast in southwest San Diego County Tuesday evening through about sunrise Wednesday. The city forecast calls for a low around 62 overnight.
A Slight Shower Chance Lingers Into Wednesday
Wednesday should turn mostly sunny again, with a high near 73 and light northwest winds. Thursday looks sunnier and slightly warmer at about 75 degrees, while Friday reaches near 79 under mostly clear skies. A slight chance of light showers is forecast in southwest San Diego County Tuesday evening through about sunrise Wednesday.
Weekend Heat Comes With Wind And Rough Seas
The warmest stretch arrives Saturday and Sunday, with highs near 83 degrees Saturday and around 82 degrees Sunday. Forecasters also expect offshore breezes and possibly stronger Santa Ana winds in foothills and some inland valleys, with the strongest gusts potentially reaching around 40 mph during the weekend mornings. Dry air should allow temperatures to cool efficiently overnight, even after the hot afternoons.
On the water, a Small Craft Advisory runs from 1 p.m. Tuesday through 4 a.m. Wednesday for outer coastal waters, where gusts could reach roughly 23 to 29 mph and seas will turn rough and choppy. No land-based watches or warnings are listed for San Diego, but boaters should expect tougher conditions offshore and beach visitors should keep an eye on changing winds.
The latest forecast sharpens the overnight shower timing and adds the marine advisory to the sunny-weekend setup described in Hoodline's Monday forecast. For most city residents, the practical plan is simple: light layers in the morning, sun protection in the afternoon, and extra caution around exposed foothills, inland valleys and the ocean as the weekend warms up.
