Rest of the work week: Chilly and breezy Wednesday, then warming up

/ April 7, 2026 at 10:21 PM

A reinforcing front will push through tonight, bringing us cooler and breezy weather for Wednesday. We start Hump Day in the upper 40s to around 50°, warming to just the upper 60s in the afternoon with a mix of sun and clouds. It’s going to be a breezy day, too, with winds 15-20 MPH gusting to 30-35 MPH. This combined with dry air will increase the fire danger for Wednesday. The northeasterly winds also increase the rip current and high surf risk, with a High Surf Advisory in effect for Wednesday into much of Thursday.
