Downtown Los Angeles is getting a near-perfect spring Sunday on April 19, 2026, with mostly sunny skies, a warm high near 76°F and light southwest breezes. A shallow marine layer hanging around early should clear by mid-morning, setting up a pleasant afternoon and a mild overnight low near 56°F.
Rain Likely Tuesday, April 21, 2026
A Pacific low is lined up to push a band of light rain into the region Monday night, April 20, 2026, with precipitation most likely after 11 a.m. on Tuesday, April 21, 2026. For downtown and the basin, the National Weather Service is calling for roughly a 70% chance of measurable rain that day, with new totals generally holding to a few tenths of an inch. It will be enough to make roads slick during the midday commute, so plan a little extra time and grab an umbrella if you have outdoor plans.
Central Coast Will See The Heaviest Rain
Forecasters expect the brunt of the system to hit the Central Coast Monday night into Tuesday (April 20–21, 2026). San Luis Obispo and Santa Barbara counties could pick up 0.5–1.5 inches of rain, while Los Angeles and Ventura counties will likely see lighter totals near 0.1–0.5 inches. Rainfall rates are projected to stay modest, around 0.10–0.33 inch per hour, so widespread flooding is not anticipated. Even so, foothill drainages and urban low spots may see localized ponding, so keep an eye on updates if you are headed into coastal or foothill zones where amounts will be higher.
Winds, Marine Conditions And Commute Notes
Winds stay mostly light today but will pick up Monday into Tuesday, with south-southwest breezes around 0–10 mph and gusts near 10–15 mph. Stronger gusts between 20–40 mph remain possible over the mountains and parts of the Central Coast. Mariners should monitor marine forecasts later in the week for possible Small Craft Advisories, and drivers should plan on breezier conditions Wednesday through Friday (April 22–24, 2026) as northwest winds increase. There are no active watches or warnings for Los Angeles proper at this time, but it is worth checking National Weather Service updates before you hit the road or the water.
Quick Take
Soak up the sunshine on Sunday, April 19, 2026, then be ready for showers on Tuesday, April 21, 2026, especially if you are driving during the midday commute. For background on the recent warm stretch and how this system evolved, see our earlier breakdown of the weekend soaker setup.
