San Diego Weather Forecast for August 26, 2025: Mugginess Sticks Around

Why this matters: Staying informed about these weather patterns allows residents to plan their activities accordingly, especially during the upcoming Labor Day weekend. Understanding the potential for showers and thunderstorms can help in preparing for outdoor events and ensuring safety.

The weather pattern for San Diego this week is influenced by a combination of factors. Initially, the weakening monsoon flow will reduce the chance of widespread thunderstorms. However, moisture from Tropical Storm Juliette will increase cloud cover and humidity, leading to potential showers, particularly on Thursday. As the week progresses, the monsoon flow will ebb and flow, bringing intermittent chances of showers and thunderstorms to the mountains and deserts. By the end of the following week, drier conditions are expected to prevail.

Temperature Breakdown:

These temperatures are near to below average through Thursday, with a slight warming trend into the weekend before another dip next week.

Expect temperatures in the 70s and 80s at the coast, 80s and 90s inland, 80s in the mountains, and between 105 to 110 in the deserts.

Drier and more comfortable humidity levels are expected by the end of next week.
