Downtown Los Angeles woke up Friday, July 3, under a blanket of low clouds and patchy fog, with temperatures stuck in the upper 50s to low 60s and humidity running high thanks to the marine layer. The gray start is expected to thin by late morning, giving way to partly sunny afternoons and inland highs near 79°F.
Forecasters at the National Weather Service say weak onshore flow will keep low clouds hugging the coast each night and morning, while building upper-level heights steadily nudge temperatures upward into next week. Many valley spots are expected to climb into the low 80s by midweek, and a few inland pockets could touch the 90s. There are no watches or warnings in effect for Los Angeles County at this time.
Holiday Weekend Outlook
Saturday, July 4 is expected to stay mostly cloudy along the beaches, with a high near 79°F and an overnight low around 61°F, while inland neighborhoods should squeeze out more afternoon sun. Sunday, July 5 and early next week are set to continue the slow warm-up, with most coastal areas holding in the 70s and valleys edging into the low 80s. If you have holiday plans near the water, the prime window for sunshine along the coast looks to be late morning through the afternoon.
Marine And Wind Notes
The National Weather Service also notes that winds and seas are expected to remain below Small Craft Advisory levels through Saturday, with a growing 50–70% chance of advisory-level winds in the outer waters Sunday through Tuesday. Gusty afternoon winds are likely in areas such as the Antelope Valley, though most populated foothill and basin locations should stay below advisory thresholds. Boaters and weekend sailors are urged to check the latest marine forecast before heading offshore.
What To Pack
Plan on layers: a light jacket for the cool, damp mornings and sunglasses for the brighter afternoons. If you are heading out on the water, bring windproof layers and stay on top of forecast updates, and if you are driving through coastal corridors, allow a little extra time for commutes slowed by fog.
