Santa Ana Heat Meets a Midnight Sprinkles: San Diego’s Dynamic Sunday Forecast

A Sunny Surge with a Windy Twist

San Diego residents are waking up to a day of dramatic shifts this Sunday, March 8, 2026. As the region navigates the first day of Daylight Saving Time, the weather is matching that brisk pace with a combination of unseasonable heat, lingering Santa Ana winds, and a late-night threat of rain. It is a day that will require both sunglasses for the afternoon and an umbrella for the commute home tonight.

Morning: A Chilly Start to a Warm Climb

Early risers—who may be feeling the lost hour of sleep—faced a chilly start with temperatures in the 40s and 50s across the valleys and coastline. However, the cool morning air will not last long. Clear skies and a building high-pressure system are expected to drive temperatures up rapidly. By 10:00 AM, most of the region will climb into the upper 60s, transitioning into a bright, mostly sunny morning.

Afternoon: Peak Heat and Wind Advisories

The afternoon will likely be the warmest part of the week for San Diego. Inland areas and downtown are forecast to hit a high near 86°F, while coastal communities like La Jolla will enjoy slightly milder temperatures in the mid-to-upper 70s. While the sunshine is abundant, the National Weather Service has issued a Wind Advisory in effect until 5:00 PM PDT. Northeast winds of 20 to 30 mph are expected in the valleys and mountains, with isolated gusts reaching 50 to 55 mph, particularly in the foothills. High-profile vehicles should exercise caution on east-west corridors.

Evening: Clouds Roll in Ahead of Rain

As the sun sets around 5:50 PM, the atmosphere will begin to shift. A low-pressure system moving in from the south will bring increasing cloudiness throughout the evening. Temperatures will drop back into the mid-50s by late tonight. Weather models indicate a significant change after dark, with a 40% chance of showers developing after 10:00 PM and continuing into early Monday morning.

Summary of Today's Conditions

• Temperature Range: High of 86°F (inland) to a low of 51°F-56°F.
• Wind Alerts: Wind Advisory until 5:00 PM; gusts up to 55 mph in mountain and valley regions.
• Rain Probability: 10% during the day, increasing to 40% late tonight (after 10:00 PM).
• Coastal Warning: Moderate rip current risk; wave heights between 2 and 4 feet.

San Diegans are encouraged to stay hydrated during the afternoon peak and secure any loose outdoor items that could be affected by the gusty Santa Ana conditions before the winds subside this evening.
