Santa Ana Winds Bring Unseasonable Heat: San Diego Braces for Gusty Wednesday

Unseasonable Heat and High Winds Gripping San Diego

San Diegans waking up this morning, Wednesday, February 4, 2026, will find a significant shift in the weather as Santa Ana conditions sweep across the region. As the lead editor for sandiego.news, I am tracking a day that will feel more like late spring than early February. A combination of offshore winds and high-pressure systems is pushing temperatures well above average, making today the warmest day of the week for many neighborhoods.

Morning Forecast: Gusty Starts and Clear Skies

The day began with a Wind Advisory, which officially took effect at 4:00 AM. In the early morning hours, skies remain clear and the air is noticeably dry. Temperatures started in the low 50s, but they are climbing rapidly as the offshore flow takes hold. If you are heading out for an early commute or morning walk, be prepared for breezy conditions, particularly in the foothills and mountain passes where the wind is strongest.

Afternoon Predictions: Record-Challenging Temperatures

By the afternoon, San Diego will experience its peak heat for the week. Inland valleys are expected to reach the mid-to-upper 80s, with some localized spots potentially touching the 90-degree mark. These temperatures are roughly 15 to 20 degrees above the seasonal norm. Coastal areas will be slightly more moderate but still very warm, with highs ranging from 71°F to 80°F under mostly sunny skies.

• Inland Valleys: Highs of 84°F to 88°F.
• Coastal Communities: Highs of 70°F to 75°F.
• Mountain Regions: Highs near 70°F with significant wind gusts.
• Desert Areas: Highs in the low 80s.

Evening Outlook: Cooling and Increasing Clouds

As the sun sets around 5:24 PM, the heat will begin to dissipate, though the Wind Advisory remains in effect throughout the night. Evening temperatures will drop back into the 50s across most of the county. While the day is predominantly clear, residents should expect some cloud cover to move in late tonight, with a very slight 10% chance of light moisture as the atmosphere begins a slow shift toward a cooler pattern expected for the second half of the week.

Wind and Fire Safety Warnings

The National Weather Service has issued a Wind Advisory that persists until noon Thursday. Residents should be aware of the following conditions:

• Mountain and Coastal Slopes: Wind gusts ranging from 35 to 50 mph.
• Inland Valleys: Wind gusts between 25 and 35 mph below mountain passes.
• Safety Precautions: Secure outdoor furniture, be cautious when driving high-profile vehicles on east-west routes, and remain vigilant regarding fire safety due to the extremely dry humidity levels.
