San Diego is in for a treat this week as an unexpected surge in temperatures will make it feel more like mid-spring than late February. Clear skies and mild conditions have already set the stage for what’s shaping up to be one of the warmest weeks of the season so far.
As of Sunday night, temperatures sat at a pleasant 60°F (16°C) under cloudless skies. But this is just the beginning. A strong high-pressure system is settling over the region, pushing temperatures well beyond their usual February averages. By midweek, San Diego could see highs reach 81°F (27°C), a significant jump from the usual 60°F (16°C) seen at this time of year.
Breaking Down the Week’s Forecast
Monday will start the trend with bright, sunny skies and a high of 70°F (21°C), cooling off to 50°F (10°C) at night. On Tuesday, expect more of the same, with temperatures inching up to 72°F (22°C).
By Wednesday and Thursday, the warm spell hits its peak. Daytime highs will reach 80-81°F (26-27°C), bringing an early taste of spring. It will still be comfortable in the evenings, with lows in the mid-50s°F (12°C).
By Friday, a shift begins. While the day will still be warm at 69°F (20°C), a possible stray shower could cool things down slightly. The cooldown continues into Saturday, with highs dipping to 66°F (19°C).
Why Is It So Warm Right Now?
The sudden rise in temperatures is due to a high-pressure system hovering over California and the southwestern U.S. This system prevents cooler air and moisture from moving in, allowing heat to build up over time. With clear skies and little ocean breeze to counteract it, San Diego is experiencing a heatwave far earlier than usual.
While these warm temperatures are perfect for beach outings, hikes, and outdoor dining, they also raise questions about how quickly California is moving toward a drier, hotter spring. If this pattern continues, it could mean an early start to wildfire season in the coming months.
How Long Will the Warm Weather Last?
The heat won’t stick around forever. By the weekend, a cooler marine layer may return, bringing temperatures back into the high 60s°F (19-20°C). There’s even a small chance of light showers on Friday, though it’s too early to tell if it will bring any significant rain.
Even with the expected cooldown, San Diego will still enjoy mild and comfortable conditions, making it a great time to get outside before spring officially arrives.
What Should You Do to Stay Safe?
Even though these temperatures aren’t extreme, they are still above normal, which means it’s important to take precautions if spending extended time outdoors.
- Stay Hydrated. Warmer days can be deceiving, especially with low humidity. Drink plenty of water throughout the day.
- Use Sunscreen. With strong, direct sunlight, UV levels will be higher than usual for this time of year. Protect your skin to avoid sunburn.
- Plan Outdoor Activities Wisely. If you’re heading for a hike or beach trip, aim for morning or late afternoon to avoid the strongest sun exposure.
- Be Aware of Ocean Conditions. Warmer weather often draws more people to the coast, but sneaker waves and strong rip currents are still a risk.
Final Thoughts: Enjoy the Warmth While It Lasts
San Diego’s weather is offering an early preview of spring, and residents should take advantage of it while they can. However, keep an eye on the forecast, as changes could be coming by the weekend. Whether you’re heading to the beach, taking a scenic drive, or simply enjoying lunch outdoors, this week’s warmth is a rare February gift.
