San Francisco is experiencing an unexpected weather twist as temperatures soar into the 70s and low 80s, surprising locals with a burst of warmth that feels more like summer than late February. While this heatwave may feel like a rare treat, there’s a catch. This warmth is caused by a low-pressure system off the coast of California, which has temporarily slowed its progression, allowing more sunshine and warm winds to sweep across the Bay Area. The Bay Area is seeing the effects in full force, with places like San Francisco, the North Bay, the East Bay, and the Peninsula reaching temperatures in the mid-60s to upper 70s.
However, don’t get too comfortable just yet—this warmth is expected to be short-lived. By Friday, the low-pressure system is expected to move closer to the Bay Area, bringing more unpredictable weather patterns and a possible dip in temperatures. These low-pressure systems are called “cutoff lows,” because they don’t follow the usual large-scale atmospheric flow. As a result, they can be tricky to forecast and often leave meteorologists scrambling to get the timing and impacts right. While the exact details of the storm system’s trajectory are still unclear, it’s safe to say that this warm spell won’t last much longer.
But that’s not all—while San Francisco enjoys a brief warm-up, a far more dangerous situation is unfolding along the coast. From Friday night through Monday, a fresh round of long-period swells is expected to hit the region, creating hazardous and potentially life-threatening conditions for beachgoers. Wave heights could reach as high as 20 feet along west-facing beaches, increasing the risk of dangerous sneaker waves and rip currents. Local officials are urging everyone to stay far from the shoreline, particularly near jetties, rocks, and piers. For those planning to visit the coast, it’s essential to follow all safety warnings to avoid getting caught in a dangerous situation.
Forecast Highlights:
-
Friday, Feb. 28: The warm weather persists for one more day before a slight drop in temperatures. Expect highs near 60°F (16°C) and increasing cloud cover as the low-pressure system begins to make its presence known.
-
Saturday, Mar. 1: The shift in weather continues with mostly cloudy skies and cooler temperatures, reaching just 57°F (14°C). A few showers are possible, so make sure to carry an umbrella.
-
Sunday, Mar. 2: Showers will become more likely throughout the day as the low-pressure system strengthens. Temperatures will remain cool at around 58°F (14°C), so be prepared for a gray and damp Sunday.

Wednesday, Mar. 5: The morning will start with rain, but sunshine should break through as the day progresses, giving you some much-needed rays by afternoon.
Safety Tips:
-
Coastal Hazards: If you’re planning on visiting any of the Bay Area’s famous beaches, keep in mind that the dangerous conditions are expected to last through the weekend. Do not venture too close to the water or any unstable rocks—rip currents and sneaker waves are a very real threat during these high-swell events.
-
Heat Precautions: Although San Francisco’s weather feels like a warm getaway, remember to stay hydrated and protect your skin from the sun’s rays. Don’t let the warmth trick you into thinking it’s safe to overexert yourself. Take breaks, stay in the shade, and keep cool wherever you can.
With temperatures fluctuating and coastal dangers escalating, San Francisco’s weather is anything but predictable. Be sure to stay updated on any changes, and take precautions to stay safe while enjoying what little warmth remains.
