Temperatures in Pasadena will climb to near 90 degrees Wednesday, marking the peak of a midweek warmup before cooler conditions arrive this weekend, according to forecasters with the National Weather Service Los Angeles/Oxnard office.
Sunny skies and light winds will dominate Wednesday, with highs near 90 and overnight lows around 66. Forecasters said weak offshore flow has cleared marine layer clouds from inland areas, allowing temperatures to rise 5 to 10 degrees above normal.
Thursday will remain warm, with highs near 89 under sunny skies. Winds will be calm in the morning, shifting south-southwest by afternoon. Friday is expected to be slightly hotter, reaching 92, before patchy fog develops late at night.
The warming trend reflects a ridge of high pressure and offshore breezes earlier in the week. By Saturday, highs will ease to around 91 with partly sunny skies and morning fog. Sunday will be cooler, with highs near 84 and partly cloudy conditions.
No rain is forecast for Pasadena through the weekend. Forecasters noted that distant hurricanes could send large swells and dangerous rip currents to Southern California beaches, though precipitation is unlikely to reach Los Angeles County.
Winds will remain light throughout the week, generally calm in the mornings and shifting southwest in the afternoons. Offshore breezes contributed to the heat, while onshore flow later will help moderate temperatures.
Pasadena residents should prepare for warm afternoons through Friday, with cooling relief expected by Sunday. Outdoor activities may be more comfortable over the weekend as temperatures return closer to seasonal norms.
No advisories are currently in effect for Pasadena, though residents planning coastal trips should monitor surf warnings tied to hurricane swells.
Looking ahead, Monday will bring sunny skies and highs near 82, followed by a slight rebound Tuesday with highs near 87. Forecasters expect mostly clear conditions into next week as a ridge builds back over the region.
In summary, Pasadena’s hottest day of the week arrives Wednesday, with highs near 90 before a gradual cooldown into the weekend. Residents can expect sunny skies, light winds, and more seasonable temperatures by early next week, according to the National Weather Service.
