Meteorologists are forecasting a significant warm-up across the San Francisco Bay Area over the next few days, with temperatures expected to climb into the upper 60s and low 70s - about 10 degrees above normal for this time of year. The warmer conditions are being driven by a diminishing marine layer and high-pressure ridges that have been diverting typical winter storm systems to the north.

Why it matters

The unseasonably warm weather will provide a welcome respite from the typical cool and rainy February conditions in the Bay Area, but it also raises concerns about beach safety and the potential for records to be broken. The forecast highlights the region's ongoing battle with climate change and the unpredictable nature of weather patterns.

The details

According to Brayden Murdock, a meteorologist with the National Weather Service's Bay Area office, the warm-up will be most pronounced in inland areas, with San Jose potentially reaching the 70s and Monterey County seeing highs in the mid-70s, with some mountain terrain reaching up to 80 degrees. However, the lack of the marine layer will also lead to chillier overnight lows, with interior portions of the Bay Area dipping into the upper 30s.

  • The warmest day of the week is expected to be Wednesday, February 5, 2026.
  • On Saturday, January 31, 2026, the Salinas Airport tied its record high of 79 degrees previously set in 1976.

What they’re saying

“Our upper-level pattern has been kind of weird. Most winter seasons in the region are distinguished by a string of low-pressure systems that produce the 'big rainmakers' the Bay Area typically sees this time of year. However, those systems have been charting north due to ridges of high pressure that have been off and on over the last couple of months.”

“It's not feeling too much like February, that's for sure. It'll be a pretty notable warm up.”

What’s next

The National Weather Service will continue to monitor the forecast and provide updates as the warm weather pattern unfolds in the Bay Area.

The takeaway

The unexpected warm-up in the Bay Area highlights the region's ongoing battle with the effects of climate change, as weather patterns become increasingly unpredictable. While the respite from typical February conditions may be welcome, it also raises concerns about beach safety and the potential for records to be broken, underscoring the need for continued vigilance and adaptation in the face of a changing climate.
