What’s Behind This February Warmth in San Jose?
San Jose is no stranger to warm temperatures in the spring and summer, but this early February warmth is unusual. Why is it happening? The cause is a shift in atmospheric pressure that has allowed warmer air from the south to push into the Bay Area.
This warm air has been trapped over the region due to a high-pressure system, leading to above-average temperatures for the last several days. Typically, San Jose would experience highs in the 50s and 60s during February, but this warmth has pushed those temperatures into the 70s, making it feel more like spring than winter.
This shift is part of a broader trend affecting much of California, as the state continues to experience mild winter conditions. Weather experts are keeping an eye on this unusual pattern to see if it could lead to more above-average temperatures in the coming weeks.
What Does This Mean for San Jose?
While this unseasonable warmth is a welcome break from the typical winter chill, it’s important to keep in mind that warmer temperatures may not last forever. While temperatures may cool slightly next week, it’s possible that San Jose will continue to experience above-average conditions in the near future.
As the days warm up, local residents are encouraged to stay hydrated and protect themselves from intense sun exposure, especially as outdoor activities pick up. While this may feel like an early spring, the city should still remain cautious as winter weather can often make an abrupt return.
How to Stay Safe During the Unseasonable Warmth
- Wear sunscreen: Even though it’s February, the sun can still have a strong effect, so protect your skin when spending time outdoors.
- Stay hydrated: The warmth can lead to dehydration, so drink plenty of water throughout the day, especially if you’re outside for long periods.
- Check on pets and elderly neighbors: As temperatures rise, it’s important to ensure pets and vulnerable individuals are comfortable and safe from the heat.
- Dress for the conditions: While temperatures are higher than usual, mornings and evenings can still be cool, so layer accordingly to stay comfortable.
When Will the Warmth End?
Good news! While this warm spell is rare for February, it’s expected to continue through the weekend, with temperatures dipping back into the 60s by next week. By early March, San Jose will return to more typical winter conditions, with cooler nights and highs in the 50s and 60s.
In the meantime, enjoy the warm weather and keep an eye on the forecast for any changes. It’s a perfect time to enjoy outdoor activities, but also a reminder to stay prepared for when the cooler weather returns.
