San Diego’s weather is doing what it does best—keeping everyone on their toes. As February winds down, the city is in for a mix of chilly, foggy mornings followed by clear, sunny afternoons that feel almost like spring. If you’re heading out early in the day, expect to see gray skies and maybe even some drizzle, but by the afternoon, you might be shedding your layers as the sun breaks through.
This kind of weather pattern isn’t new to San Diegans, but if you’re visiting or new to the area, it can feel like a daily surprise. One minute, it’s misty and cool, the next, you’re basking in 70-degree sunshine. So, what’s causing these shifts? And how should you plan for the week ahead? Let’s break it down.
Current Conditions: A Gloomy Start to the Day
San Diego is waking up to foggy conditions and a cool 55°F (13°C). Some areas may even see light drizzle, making for a damp commute. But don’t worry—this won’t last all day. As the morning progresses, the sun will start to break through, warming things up to a high of 64°F (18°C) by the afternoon. If you’re heading out tonight, expect cooler temperatures dropping to 49°F (9°C).
This pattern of morning gloom burning off into sunshine will be the theme of the week, but temperatures will gradually climb, giving us a warm and pleasant weekend ahead.

If you’ve got weekend plans, you’re in luck. The weather is shaping up to be near perfect with plenty of sun and comfortable temperatures.

Next Week: A Gradual Climb Toward Warmer Days

Why Is San Diego’s Weather So Unpredictable?
If you’ve lived in San Diego for a while, you know this routine well. The cool, damp mornings followed by sunny, warm afternoons are all thanks to the marine layer. This happens when warm air meets the cooler ocean air, creating low clouds and fog that settle over the city overnight and into the morning.
As the sun rises, it heats the land, pushing that cool air away and replacing it with sunshine. That’s why the mornings can feel like a different season than the afternoons! This is one of the reasons San Diego has such mild and pleasant weather year-round.
How to Prepare for the Week Ahead
- Dress in Layers: Mornings will be cool and damp, but by the afternoon, you might be comfortable in short sleeves.
- Keep an Umbrella Handy (Just in Case): Light drizzle is possible in the early mornings, especially near the coast.
- Enjoy the Sunshine: Once the fog clears, San Diego will be warm, bright, and perfect for outdoor activities.
- Expect Cool Evenings: Nights will still be on the chilly side, so bring a light jacket if you’re going out late.
Bottom Line: A Classic San Diego Week Ahead
San Diego’s weather this week will deliver exactly what the city is known for—mild, comfortable days with a mix of coastal fog and golden sunshine. It’s the kind of forecast that lets you enjoy morning coffee wrapped in a sweater and an afternoon walk in a t-shirt.
So whether you’re heading to work, planning a weekend adventure, or just soaking in the sunshine, be ready for the daily shift from morning gloom to afternoon glow. It’s a classic San Diego forecast—and one that never really gets old.
