Downtown Los Angeles is lined up for a bright, mild Wednesday, April 22, with mostly clear skies and a high near 72°F following an overnight low around 55°F. West-southwest sea breezes will build through the afternoon, with gusts topping out around 20 mph in parts of the basin, strongest near exposed freeway ramps and passes. The coast will run a bit cooler, inland pockets a bit warmer, and you will probably want a light jacket after sunset as temperatures slide into the low 50s.
Afternoon Winds Pick Up
Winds will gradually ramp up into the afternoon and early evening, generally holding near 0–10 mph but occasionally gusting to about 20 mph. Late tonight, the flow shifts more northwest, keeping some gusty spots near the I-5 corridor and into the Antelope Valley. According to the National Weather Service Los Angeles/Oxnard, those gusts should stay just under advisory criteria for most locations. Drivers in high-profile vehicles and anyone taking exposed ramps should plan for noticeable crosswinds and build in a little extra travel time.
Coast Versus Downtown
The beefed-up sea breeze will keep beachfront neighborhoods a few degrees cooler than downtown, where afternoon readings are expected to land in the low 70s.

Evening lows will drop into the low 50s across much of the basin, leaving outdoor dinners and patio hangs comfortable but on the brisk side.
Weekend And Near-Term Outlook
A weak system is expected to brush past the region on Saturday, bringing some extra cloud cover and only a slight chance of light rain over the mountains while daytime highs cool into the mid-60s. Ridging is forecast to return Sunday into Monday, with dry weather and highs rebounding into the low 70s. Late Monday into Tuesday, guidance becomes less certain, with a small 10–15% chance of showers creeping back into the picture.
Boaters And Mariners
Small craft advisory conditions are anticipated for parts of the local waters from this afternoon into tonight, so mariners should check the latest forecasts and secure loose gear before heading out. Anyone planning time on the water is advised to monitor local marine products and consider postponing nonessential trips while gusts are at their peak.
