Clear Skies and Coastal Gusts: San Diego’s Tuesday Outlook

Mid-March Sunshine Takes Center Stage

San Diegans are waking up to a quintessential Southern California day this Tuesday, March 10, 2026. After a dynamic start to the month, the current weather pattern has settled into a stable, sunny rhythm. Local residents can expect clear skies throughout the day with temperatures remaining near the seasonal average, providing a perfect backdrop for outdoor activities, provided you are prepared for some brisk coastal breezes.

Morning: A Crisp and Bright Start

The morning hours will begin with a refreshing chill, as temperatures hover in the low-to-mid 50s. Humidity is notably high this morning at approximately 87%, which may lead to some light mist in low-lying inland valleys, but this will burn off quickly as the sun rises. Winds will be light initially, coming from the north-northwest at about 6 to 8 mph. If you are heading out for an early walk at Balboa Park or a commute along the I-5, a light jacket is recommended to cut through the early morning air.

Afternoon: Peak Sun and Pleasant Highs

As we move into the afternoon, San Diego will see peak sunshine with virtually zero percent chance of precipitation. The high temperature for today is forecasted to reach a comfortable 67°F (19°C) along the coast, with slightly warmer peaks of 70°F in the inland valleys. While the sun will be bright, the National Weather Service has issued a Wind Advisory for coastal and mountain regions. Sustained winds are expected to increase to 15-20 mph, with occasional gusts reaching up to 30 mph. This may create choppy conditions for those planning to be out on the water or visiting the local piers.

Evening: Clear Skies and a Cool Descent

The clear conditions will persist well after sunset, which is scheduled for 5:52 PM. Evening temperatures will drop steadily, reaching a low of 53°F (12°C) overnight. The lack of cloud cover means the heat will escape quickly, so diners planning to enjoy outdoor seating in the Gaslamp Quarter or Little Italy should keep those heaters nearby. Humidity will climb back up toward 90% late tonight, but the dry air mass moving in from the desert should keep any significant fog at bay.

Weather Safety and Marine Notices

• Wind Advisory: Be cautious of gusty conditions, especially when driving high-profile vehicles on the Coronado Bridge or along the coast.
• UV Index: The UV index is expected to be high today; remember to apply sunscreen if you are spending more than 20 minutes outdoors.
• Marine Forecast: Small craft should exercise caution as gusty winds may lead to increased swell height and choppy surface conditions.

Overall, it is a spectacular day to be in San Diego. Enjoy the sunshine, secure your patio umbrellas against the afternoon gusts, and take advantage of the beautiful, clear March weather.
