San Jose is gearing up for a dramatic weather shift this week, with temperatures spiking to near summer-like warmth midweek before a cool-down and rain return by the weekend. If you’re planning to be outdoors, enjoy the sunshine and warmth while it lasts—because change is coming fast.
Currently, San Jose sits at a mild 55°F (13°C) under mostly cloudy skies. The day ahead will be pleasant, with a high of 67°F (19°C), making it a great time to be outside before temperatures take a big leap midweek.
How Warm Will It Get?
A high-pressure system moving into California will bring unseasonably warm weather midweek, pushing daytime highs into the mid-to-upper 70s. However, by the weekend, a cold front will arrive, bringing increased cloud cover and a chance of rain.
Here’s a breakdown of what to expect each day:
- Tuesday, February 25: Mostly sunny, warming up to 69°F (20°C), low of 42°F (6°C).
- Wednesday, February 26: The warmest day of the week! Lots of sunshine, high of 77°F (25°C), cooling to 50°F (10°C) at night.
- Thursday, February 27: A few high clouds but still warm, high of 74°F (23°C), low of 49°F (10°C).
- Friday, February 28: Mild and sunny, high of 72°F (22°C), low of 48°F (9°C).
- Saturday, March 1: Clouds increase as temperatures start to dip, high of 67°F (20°C), low of 52°F (11°C).
- Sunday, March 2: Morning rain and drizzle expected, high of 64°F (18°C), low of 47°F (8°C).
Why Is San Jose Heating Up?
This week’s warming trend is caused by a high-pressure system pushing in from the Pacific, trapping heat and bringing drier, sunnier conditions.
But by the weekend, this high-pressure system will weaken, allowing a low-pressure system to move in from the northwest. This will bring increased moisture, leading to cloudier skies and the possibility of showers.
This rollercoaster pattern is common for late February and early March, when California transitions from winter into spring-like conditions.
What This Means for San Jose Residents
With temperatures swinging from near 80°F down to the low 60s with rain, this is the kind of week where you’ll need both sunglasses and an umbrella.
Here’s how to prepare for the changing conditions:
- Enjoy the Warmth While It Lasts – The best days for outdoor plans are Wednesday through Friday, before the clouds and rain move in.
- Stay Hydrated and Wear Sunscreen – Even though it’s February, the midweek sun will be strong.
- Watch for Changing Conditions by the Weekend – Saturday will start warm, but Sunday could bring wet roads and cooler temps.
- Dress in Layers – Mornings will be chilly early in the week, but afternoons will warm up fast.
How Long Will the Warmth Last?
The warm weather will hold steady through Friday, but by the weekend, temperatures will cool off again.
Long-term forecasts suggest another warm-up could return next week, but March is known for its unpredictable weather swings. For now, this week’s warm spell will be short-lived, making way for cooler, wetter conditions ahead.
Final Thoughts – Enjoy the Sunshine Before the Rain Arrives!
San Jose is in for a classic weather shift—warm, sunny days midweek followed by a weekend cooldown and possible rain.
