San Diego is about to experience a dramatic shift in weather, with unseasonably warm temperatures taking hold before cooler conditions return later this week. While February is typically mild in Southern California, a high-pressure system is bringing a surge of warmth, pushing temperatures into the mid-70s. But don’t get too comfortable—the warmth won’t last long. A cooldown is set to follow, along with strong gusty winds that could impact travel and outdoor activities.
Why Is San Diego Warming Up?
The brief warm spell is being driven by a high-pressure system settling over the region. This system is blocking colder air from moving in and allowing warm, dry air to dominate. As a result, San Diego is seeing temperatures rise well above the February average of 63°F (17°C), creating ideal conditions for outdoor activities.
However, this pattern won’t last. By the end of the week, the high-pressure system will weaken, allowing cooler ocean air to push back inland. Along with dropping temperatures, a developing low-pressure system is expected to bring increasing cloud cover and even a slight chance of rain by Sunday.
The 5-Day Forecast: What to Expect
- Thursday, February 27: The warmest day of the stretch! Expect plenty of sunshine and a high of 75°F (24°C), with a mild nighttime low of 51°F (10°C).
- Friday, February 28: The cooldown begins. Partly sunny skies and noticeably cooler temperatures, with a high of 63°F (17°C) and a low of 53°F (11°C).
- Saturday, March 1: More sunshine returns, but temperatures stay cooler at 66°F (19°C). Overnight lows around 54°F (12°C).
- Sunday, March 2: Increasing clouds with a chance of scattered showers in some areas. Highs will be near 65°F (18°C), with overnight temperatures dropping to 51°F (11°C).
Strong Winds Could Cause Problems
While the warmth is a welcome change, it comes with a catch—gusty winds are also expected to pick up. The National Weather Service has issued a Wind Advisory from midnight Wednesday to 4 PM Thursday, warning that east winds could reach 20-30 mph, with gusts up to 55 mph in certain areas. These strong winds could create hazardous driving conditions, especially for high-profile vehicles, and residents should secure any loose outdoor furniture or decorations.
How to Prepare for the Weather Changes
If you’re planning to enjoy the warm weather, make sure to stay hydrated and wear sunscreen, as the sun combined with dry air can cause dehydration faster than expected. With the wind advisory in effect, be cautious when driving in exposed areas or near the coast, where gusts can be stronger.
By the weekend, cooler conditions will return, and there’s even a chance of light rain by Sunday. While it won’t be a major storm, it’s a reminder that San Diego’s winter season isn’t over just yet.
Looking Ahead: More Weather Swings on the Way?
As March approaches, forecasters expect more rapid weather shifts. These swings between warm, dry conditions and cooler, wetter periods are common in Southern California this time of year. While long-term forecasts don’t show any major storms on the horizon, another round of temperature swings is likely in the coming weeks.
