San Diego is kicking off the week under gray skies and lingering showers, but don’t let the gloomy start bring you down. A major shift is coming, and by the time the weekend rolls around, you’ll be soaking up the sun with clear skies and spring-like warmth.
If you’ve been craving a break from the cloudy, damp conditions, you’re in luck. Here’s what to expect day by day as San Diego transitions from overcast and cool to warm and gorgeous.
A Cloudy, Damp Start to the Week
Monday, February 17, begins on the gray and drizzly side, with light showers and overcast skies hanging over the city. Temperatures will stay mild, peaking at 63°F (17°C) before dipping to a chilly 51°F (10°C) at night. While the rain won’t be heavy, it’s just enough to make morning commutes damp and dreary.
Tuesday, February 18, starts off much the same, but a break in the clouds is expected by afternoon. Temperatures remain steady, with a high of 63°F (17°C) and overnight lows around 48°F (9°C). If you’re heading outside, a light jacket and umbrella might still come in handy.
Midweek: The Sun Starts to Show Itself
By Wednesday, February 19, the gray skies will begin to retreat, with more sunshine pushing through by the afternoon. Highs will inch up slightly to 64°F (18°C), while nighttime temperatures hover near 50°F (10°C). The air will still feel crisp in the mornings, but as the sun lingers longer in the sky, it’ll feel warmer and more inviting.
Thursday, February 20, marks a clear shift in the pattern. The morning will start with some low clouds, but by midday, expect bright sunshine. Daytime highs will stay around 64°F (18°C), but with less cloud cover, it’ll feel much warmer in direct sunlight. If you’ve been waiting for an excuse to spend time outside, this is the day to start making plans.
The Weekend Brings Warmth and Sunshine
By Friday, February 21, the warm-up is in full swing. Highs will jump to 69°F (21°C), and the sunshine will be abundant throughout the day. Even the nighttime temperatures will start creeping up, settling at a comfortable 48°F (9°C). The combination of blue skies and mild warmth makes this the perfect start to an ideal San Diego weekend.
Saturday, February 22, brings more of the same gorgeous weather, with temperatures rising to 71°F (22°C). Expect crystal-clear skies and gentle breezes, making it a fantastic day for outdoor adventures, whether it’s hiking, hitting the beach, or dining al fresco.
Sunday, February 23, is the true crown jewel of the week. The forecast calls for sunshine all day long, with temperatures reaching a beautiful 72°F (22°C). If you’ve been missing warm, sunny weather, this is the day to embrace it—whether that means a picnic in Balboa Park, a stroll along the coast, or simply relaxing in the backyard with a cold drink.

How to Make the Most of the Weather Shift
- Plan for a Wet Start – While the early part of the week isn’t a complete washout, light rain and overcast skies could make outdoor plans less enjoyable. Have a backup plan for Monday and Tuesday.
- Dress in Layers – Mornings will stay on the cooler side through midweek, so bring a jacket or sweater if heading out early.
- Weekend Outdoors? Yes, Please! – With temperatures in the low 70s and full sunshine, this is the best weekend in weeks for outdoor plans. Whether you’re hiking, biking, or hitting the beach, this is your time to enjoy it.
- Sunscreen is a Must – Even though it’s February, the UV index in San Diego remains strong. Don’t let the mild temperatures fool you—the sun is intense, so protect your skin.
What’s Next?
Forecasters say this warm, dry pattern could continue into the following week, with no major storms on the horizon. That means more sunshine and mild temperatures, keeping San Diego in perfect winter-spring transition mode.
So while the week may start off on the gloomy side, don’t be discouraged—by the weekend, it’ll be warm, bright, and absolutely beautiful. Get ready to soak up the sun and enjoy San Diego at its finest!
