If you’ve been enjoying the cool spring weather, brace yourself—things are about to heat up! The San Joaquin Valley and Sierra Foothills are looking at 85°F temps (or higher!) by Tuesday, making it feel more like late May or June than mid-March.
This sudden warm-up is thanks to a high-pressure system rolling in, trapping heat and sending temperatures well above normal for this time of year. And here’s the kicker—this heat isn’t just for one day. The warm spell is expected to stick around for a few days, keeping things toasty all week.
Where Will It Be Hottest?
If you live in the San Joaquin Valley, expect the heat to hit hardest in places like:
Fresno
Bakersfield
Stockton
Modesto
And if you’re in the Sierra Foothills—think Auburn, Sonora, and Mariposa—you’ll also be feeling warm afternoons and mild nights.
Why This Heat Matters
It’s an Early Taste of Summer – Normally, highs this time of year sit in the 70s, so an 85°F day is a big jump. Your body might not be used to the heat yet, making dehydration or heat exhaustion more likely.
Fire Risk is Creeping Up – Warm, dry, and breezy conditions can dry out vegetation quickly. It’s not wildfire season yet, but an extended warm spell could increase the risk, especially in the foothills.
Warm Days, Mild Nights – Even after the sun sets, temps will only drop into the 50s, meaning homes and buildings won’t get much of a break from the warmth.
How to Handle the Heat Like a Pro
Drink Plenty of Water – Even if you don’t feel thirsty, stay hydrated! The sudden warmth can catch people off guard.
Keep Your Home Cool – Shut the blinds or curtains in the afternoon to block out direct sunlight and keep indoor temps down.
NO Pets or Kids in Cars—Ever! – A parked car heats up scary fast, even at 85°F. Just don’t do it.
Plan Outdoor Time Wisely – If you need to be outside, try to get things done in the morning or evening when it’s cooler.
It might still say “spring” on the calendar, but Tuesday is bringing the heat to California’s San Joaquin Valley and Sierra Foothills. If you’re in these areas, expect hot afternoons, mild nights, and dry conditions.
