Downtown Los Angeles rolled into Friday under mostly cloudy skies and a mild mid-50s start. After a run of unseasonably warm days, the basin is in for a noticeable cooldown, with afternoon highs near 72°F and a light southeast breeze. Keep an eye on the higher terrain this afternoon, since a few mountain showers could pop up, and there is a small chance of an isolated thunderstorm.
Afternoon Shower Threat
A weak upper-level trough sliding along the coast will focus the best shot at scattered showers over the mountains this afternoon and evening, especially across northern Ventura County and the Santa Barbara backcountry. Any storm cells that do develop could bring gusty outflow winds and dry lightning, which means brief, localized bursts of wind and sudden clouds and rain near ridge roads. Drivers making pass crossings should be ready for quick shifts in visibility and changing road surface conditions.
Weekend Rebound And Context
The cool spell will not last long. Temperatures bounce back Saturday into the mid-70s, and inland spots could climb into the low 80s by Sunday. We broke down the midweek heat in our coverage yesterday, tracking how downtown pushed into the upper 80s before today’s trough moved in. Upper-80s heat downtown.
Coastal Hazards And Boating
Out at the coast, a long-period west swell is building along the Central Coast, driving up surf and creating dangerous rip currents under a High Surf Advisory that runs through Saturday evening. Seas may reach 10 to 12 feet in some inner waters, and Small Craft Advisories are expected in the outer waters into early next week, with a modest chance of gale-force gusts on Sunday. Boaters and beachgoers should treat conditions with respect and extra caution. For the latest watches and advisories, check the National Weather Service Los Angeles/Oxnard.
How To Plan
Today is a good day to enjoy cooler daytime weather, but you will want a light jacket once the sun dips. At the beach, stay off cliffs and jetties, follow lifeguard instructions, and consider postponing small-boat outings if any advisories are in effect. Check conditions before you head out. Another pattern change arrives next week, with a slight chance of light rain from Tuesday into Wednesday, so keep an eye on updated forecasts if you are planning extended outdoor time.
