San Diego is easing into the week partly cloudy and mild, with temperatures near 59°F at San Diego International Airport and inland areas headed for the upper 60s to low 70s by midday. Skies turn mostly sunny this afternoon with a high near 71°F, light west winds, and some gustier sea-breeze pockets along exposed coastal slopes.

Afternoon Winds Pick Up

Onshore flow will strengthen through the day, bringing breezier conditions to exposed slopes and inland valleys this afternoon and evening. West and southwest gusts are expected to reach roughly 30–40 mph across mountain and desert faces, then ramp up to more widespread 40–50 mph gusts tomorrow, with isolated bursts up to 65 mph in favored passes. Those kinds of gusts can create sudden crosswinds for high-profile vehicles. According to the National Weather Service San Diego, residents should secure loose patio furniture and use extra caution on canyon and pass routes.

Tuesday Night Chance Of Light Showers

A slight chance of mostly spotty, light showers develops tomorrow, with the best odds over the San Bernardino County mountains. This lines up with the pattern highlighted in our last Friday update on that windy inland punch, although most forecast guidance keeps moisture limited. For most neighborhoods, measurable rain still looks unlikely.

Boaters And Commuters Take Note

Winds are forecast to increase over coastal waters midweek and could create hazardous conditions for small craft on Wednesday into Thursday, so mariners should check the latest marine forecasts before heading out. Plan a little extra time for commutes across exposed bridges or through canyon passes and make sure outdoor items are tied down. Coastal mornings should stay on the cooler side, while afternoons tend to be breezy.

Bottom line: enjoy a mostly sunny day today, lock down anything that might fly away, and expect wind to steal the spotlight from tomorrow until Wednesday, especially across the mountains and deserts. We will keep an eye on any watches or advisories and update if the system’s track or rain chances change.
