Why Is San Jose Experiencing Such Big Temperature Swings?
San Jose’s weather this week is being driven by a strong high-pressure system, which is keeping storms and cold fronts away. This allows for sunny afternoons, but with clear skies at night, temperatures drop quickly.
This pattern is common in late winter and early spring, when the sun is strong enough to warm the afternoons, but the nights remain cool and crisp.
How to Make the Most of This Week’s Weather:
- Dress in layers – Cold mornings and warm afternoons mean you’ll want options. A jacket for the morning, but short sleeves by midday!
- Take advantage of the sunshine – With no rain in the forecast, this is the perfect week for hiking, biking, or spending time outdoors.
- Be prepared for chilly evenings – Temperatures will drop after sunset, so if you have dinner plans or outdoor events, bring an extra layer.
- Plan morning commutes wisely – Early temperatures will be brisk, and some areas may see light fog or cloud cover, so be ready for a cool start to the day.
Looking Ahead: Will the Warm Weather Last?
San Jose is expected to stay on a warming trend heading into early March, with no major cold fronts or storms on the horizon. While mornings will continue to feel cool for now, expect afternoons to become even milder as the days go on.
