Sun Today, Showers Tonight: San Diego Braces for a Wet Tuesday Evening

A Transition Day in America's Finest City

Today, Tuesday, February 17, 2026, San Diego is experiencing a notable weather transition. While the morning may offer glimpses of the sun, residents should prepare for a significant shift in conditions as the day progresses. Local meteorological data indicates that the region is moving from a relatively dry morning into a much wetter overnight period, characteristic of the variable conditions often seen in mid-February.

Morning and Afternoon: Mild and Partly Sunny

Throughout the morning and early afternoon, San Diego will enjoy partly sunny skies. For those heading out for a morning walk or a lunch meeting, conditions will remain largely cooperative. The daytime high is expected to reach a comfortable 61°F. Humidity levels are forecasted to hover around 68%, providing a crisp, cool coastal feel to the air. The chance of precipitation remains low during the daylight hours, sitting at approximately 20%, meaning most outdoor activities should go uninterrupted until the late afternoon.

Evening Outlook: Rain Showers Move In

The primary weather story for today develops as the sun sets. Forecast models show a sharp increase in moisture, with a 75% chance of rain showers beginning in the evening and continuing through the night. Total precipitation for this event is projected to reach approximately 0.29 inches. As the rain settles in, temperatures will dip to an overnight low of 52°F. San Diegans planning to be out after 6:00 PM are strongly advised to keep an umbrella or rain jacket handy, as the showers are expected to be persistent once they arrive.

Regional Wind and Safety Alerts

While surface winds within the city limits are expected to remain a manageable 6 mph, the National Weather Service in San Diego has issued regional alerts that commuters should keep in mind. Earlier today, a Special Weather Statement was issued regarding strong thunderstorms moving through the broader region, particularly affecting the Inland Empire and neighboring valleys. These systems have been known to produce wind gusts up to 50 mph and occasional pea-sized hail. While the most severe activity is currently focused inland, the associated front is the primary driver for the rainfall expected to hit the coast tonight.
