If you’re enjoying San Diego’s beautiful sunshine today, don’t get too comfortable. A major shift in the weather is coming, and it could hit harder than you expect. Right now, the skies are clear, the temperatures are mild, and it feels like the perfect day to head to the beach or grab an outdoor coffee. But behind the scenes, meteorologists are tracking a storm system that’s creeping toward Southern California, threatening to bring heavy rain, strong winds, and possibly even localized flooding.
San Diego may be known for its year-round sunshine, but even this coastal paradise isn’t immune to wild weather swings.
Today’s Forecast: A Picture-Perfect Day Before the Storm
For now, San Diego is delivering ideal conditions, with temperatures peaking at 66°F (19°C) and dipping to a mild 53°F (12°C) at night. Light breezes and clear skies make this a prime day for outdoor activities, whether you’re strolling through Balboa Park or catching waves at La Jolla Shores.
But as any local knows, San Diego weather can turn on a dime, and this time, the change could be dramatic.
The Storm That’s Heading Our Way – What to Expect
A Pacific storm system is building strength and is expected to reach San Diego within the next 24 to 48 hours. Unlike the quick drizzles the city often sees, this system has the potential to bring widespread rain, gusty winds, and hazardous conditions.
- Rainfall Totals: Expect anywhere between 0.25 to 1 inch of rain, with some areas receiving even more if the system strengthens. While this might not seem like much, San Diego’s dry ground and urban infrastructure often struggle with sudden downpours, leading to localized flooding in low-lying areas.
- Strong Winds: Gusts could reach up to 40 mph, especially along the coast and in the mountains. These conditions could make travel hazardous, particularly on elevated roads and bridges.
- Temperature Drop: The warm, comfortable days will be replaced by cooler, cloudier conditions, with daytime temperatures struggling to reach 60°F (15°C) once the storm arrives.

How to Prepare for the Incoming Storm
This isn’t just a light drizzle—San Diegans should take a few simple precautions to stay safe as the storm moves in.
- Secure Outdoor Items – Strong winds can knock over patio furniture, garbage bins, and decorations. Bring them inside or tie them down before the wind picks up.
- Drive Carefully – Rain can make San Diego roads slick and dangerous, especially after a long dry spell. Be extra cautious, reduce speed, and keep extra distance between vehicles.
- Watch for Flooding – Low-lying areas, including parts of Mission Valley, are known for quickly accumulating water. If you see standing water on the road, turn around—don’t risk it!
- Prepare for Power Outages – Downed trees and strong winds can sometimes knock out power lines, leading to outages. Keep flashlights, extra batteries, and a charged phone handy, just in case.
- Check the Forecast Regularly – This storm is still developing, and its strength could increase or shift. Stay tuned to the National Weather Service and local meteorologists for real-time updates.
What’s Next? Will This Storm Be a One-Time Event?
While this storm is expected to pass within a couple of days, it could be the start of a more active weather pattern for Southern California. With El Niño conditions in play, forecasters warn that more storms could follow throughout March and April.
San Diego might be known for beautiful, sunny days, but nature has a way of reminding us that it’s still full of surprises.
So, while today is a great day to enjoy the perfect weather, don’t be caught off guard when the skies turn gray. Stay informed, take precautions, and get ready—San Diego’s weather is about to take a wild turn
