Los Angeles weather today (Oct. 29, 2025): record-tying heat now, Halloween cooldown on the way

Los Angeles is sizzling under late-October heat today, with highs expected to reach 93°F—a mark that ties the daily record from 1931. Skies stay cloudless, humidity is low, and the city’s usual afternoon sea breeze will do little to dent the heat before sunset. The good news: a step-down begins Thursday, and by Halloween night, conditions look comfortably mild and dry for trick-or-treaters across the basin.

Heat peaks today, then an easy slide toward the weekend

A compact warm ridge overhead is responsible for today’s spike. Temperatures ease several degrees Thursday, fall back toward seasonal norms Friday, and settle into a pleasant, sunny pattern through early next week. Daytime warmth will linger inland, but evenings quickly trend cooler—classic late-autumn diurnal swings.

At a glance (Downtown/LA Basin):

• Today (Wed): Sunny and hot, 93/64°F — record-tying heat, hydrate and limit exertion in the afternoon.

• Thu: Very warm, 88/59°F, lighter heat, still bright.

• Fri (Halloween): Morning low clouds/fog, then sun, 79/59°F; dry evening for costumes and events.

• Sat: Mostly sunny and pleasant, 76/58°F.

• Sun: Sunny to partly cloudy, 78/53°F.

• Mon: Sunshine, 79/60°F.

• Tue: Abundant sun, 75/58°F.

Halloween forecast: clear path for costumes and crowds

After a gray start Friday with patches of marine-layer clouds and fog along the coast and some west-side neighborhoods, sunshine breaks through by midday. Evening temperatures should land in the mid–60s°F in the basin and upper–50s°F for coastal zones—ideal for outdoor gatherings without extra layers. Winds look light, with no rain in the picture.

Neighborhood notes:

• Coast (Santa Monica, Venice, South Bay): Coolest readings; Friday morning fog most likely here, then a mellow evening.

• Valleys (San Fernando, San Gabriel): Warmest today and Thursday; still comfortable by Friday night, generally a few degrees warmer than the basin.

• Inland Empire/foothills: Bigger day-night spread; plan for a crisp late evening after a warm afternoon.

Health and safety in the heat

• Hydration & timing: If you exercise outdoors today, aim for morning or near sunset and drink water before you’re thirsty.

• Sun exposure: UV remains seasonally strong under clear skies—use sunscreen and shade.

• Heat-sensitive groups: Check on older adults, small children, outdoor workers, and pets; cars heat rapidly even in October sun.

• Fire awareness: Vegetation remains dry despite cooler nights. Avoid sparks, use care with equipment, and report smoke quickly.

Why it’s so hot—and why it won’t last

A late-season ridge has parked just right to suppress the marine layer and maximize sunshine. As the ridge edges east, onshore flow gradually restores typical coastal cooling and morning low clouds. That returning marine influence is the driver behind Friday’s cloud deck and the broader cooldown into the weekend.

Planning your week around the weather

• Commuters: Today’s heat can strain vehicles and air-conditioning; carry water and allow extra time for cooling.

• Events & venues: Outdoor setups are safe from rain all week; consider shade and misting fans today and Thursday.

• Energy use: Expect higher AC demand today; the Thursday–Friday cooldown should ease evening loads.

• Recreation: Beach days remain pleasant with cooler water and light breezes; visibility may start gray on Friday before turning sunny.

Los Angeles endures a record-tying hot day today, then glides into a comfortable, dry stretch right through Halloween and the weekend. Plan for heat safety this afternoon, enjoy the milder evenings starting Thursday, and count on a dry, crowd-friendly Friday night for costumes, block parties, and neighborhood strolls.
