Summerlike heat grips L.A., San Diego: When will it end?
A sweeping heat wave grips the U.S. West, driving record-high temperatures and extended heat through much of October. Los Angeles shatters daily records with highs around 103 degrees, while other California cities endure 90s to near 100s, raising extreme heat warnings through early next week. The scorching conditions spill into major events like the NLDS games in Southern California, where even late-day play remains intensely hot. Persistent dryness and limited nocturnal relief amplify wildfire risk and strain cooling needs, with forecasts calling for above-average temperatures across the region for most of October. The outlook suggests warmth may ease slightly next weekend, but overall heat and dryness are projected to persist, elevating exposure and preparedness concerns.
Dive Deeper:
Downtown Los Angeles set a daily high of 103 degrees on Oct. 2, breaking the previous record of 101 degrees from 1995, as a broad West-wide heat surge pushes temperatures 15-25 degrees above historical averages.
Record-challenging heat is expected to endure through Oct. 9, with several California locales, including the San Francisco Bay Area and Fresno, remaining well above normal and overnight lows not cooling as much as typical for early October.
NLDS games in Dodger Stadium will be played under extreme heat conditions, with Game 1 and Game 2 forecast to be particularly hot, though temperatures may ease slightly for the later afternoon start on Game 2 as the sun sets.
San Diego reached a record high near 95 degrees late in the week, and heat could climb further into Monday before conditions ease for the Padres’ return to Petco Park for Game 3 against Milwaukee.
Forecasters attribute the heat to a persistent West-wide high-pressure ridge, with offshore winds and a reduced marine layer contributing to unusually warm inland and coastal conditions.
Officials warn that dry conditions and gusty winds increase the wildfire ignition risk across Southern California, with little relief anticipated at night throughout much of next week.
AccuWeather’s long-range team expects October temperatures to stay well above normal across much of the West, driven by dryness and occasional wind events, though a potential cooldown may arrive toward the end of the period.
