Look, if you’re planning a trip to the Sierra Nevada right now, you’ve probably seen the headlines about "weather whiplash." One week we're bone-dry, and the next, the park is getting slammed with nearly 100 inches of snow. Honestly, checking the yosemite weather 10 day forecast is the only way to stay sane when the mountains start acting up.
Right now, as of January 15, 2026, things are actually looking surprisingly mellow, but don't let the sunshine fool you. It's sunny today with a high of 51°F, but the overnight low is dropping to a bone-chilling 10°F. That’s a 40-degree swing in a single day. You basically need a wardrobe for two different planets just to survive 24 hours in the Valley.
Why the Yosemite Weather 10 Day Forecast is a Moving Target
The big thing people miss is elevation. You might see 50°F on your phone and think "hoodie weather," but that's likely the Valley floor at 4,000 feet. If you head up toward Badger Pass or try to find a trail in the high country, you're looking at a completely different world.
For the next week, the forecast stays mostly sunny with highs hovering between 40°F and 52°F through January 24. But check those lows. On Monday, January 19, it's expected to hit 6°F. That is "freeze your water bottle solid" cold.
If you're wondering about the white stuff, there's a tiny 10% chance of snow this coming Saturday and Sunday nights. It's not a major storm, but in the Sierras, a "10% chance" can sometimes turn into a surprise dusting that makes the roads a nightmare.
Breaking Down the Next 10 Days
The current trend is a slow cooling. While tomorrow, Friday, January 16, might feel great at 52°F, by next Thursday, January 22, the high will struggle to reach 40°F. Humidity is staying low—around 12% today—which means the air is crisp and clear, but it’ll dry your skin out in a heartbeat.
Wind is mostly coming from the West and East at low speeds, roughly 1 to 7 mph. It’s not enough to knock trees down, but an east wind in the winter usually brings that biting cold air down from the high peaks.
What’s Actually Open (and What’s Buried)
You can't just drive anywhere right now. Tioga Road and Glacier Point Road are shut tight for the season. They won't open until May or June of 2026, depending on how the spring melt goes.
- Yosemite Valley: Open and clear. This is where you’ll find those 50-degree days.
- Badger Pass: The ski area is the place to be if you want to actually touch the snow. They got a massive dump after Christmas, and the base is looking solid.
- Hetch Hetchy: Usually open, but they close the road if it starts snowing or if the overnight forecast looks sketchy.
The Reality of Winter Driving
Even with a "sunny" forecast, you HAVE to carry chains. It’s the law in the park during winter months, regardless of what your weather app says. I’ve seen people get turned around at the gate because they thought their AWD SUV was invincible. It isn’t.
If you're coming in from Highway 140 (the El Portal Road), it's the lowest elevation entrance and your best bet for avoiding ice. Highway 41 and 120 can get much hairier when the sun goes down and those 10-degree temps hit.
Expert Gear Tips for These Specific Conditions
Since we’re looking at clear skies but frigid nights, the "ice cone" at the base of Yosemite Falls is likely forming. It’s a spectacular sight, but the mist from the falls freezes on the trails nearby.
- Microspikes: If you’re hiking Mist Trail (the winter route), these are non-negotiable.
- Lithium Batteries: Your phone and camera batteries will die in minutes when it hits 6°F. Keep them in an inside pocket close to your body heat.
- Sunscreen: A UV index of 3 doesn't sound high, but with the sun reflecting off the granite and snow, you’ll get fried before you realize it.
Practical Next Steps for Your Trip
Stop checking the general "California" weather. It’s useless here. Instead, do these three things before you put the car in gear:
- Call the Road Hotline: Dial 209-372-0200, then press 1, then 1. This is the only way to get real-time info on chain requirements.
- Pack for 10°F: Even if you plan on being indoors by sunset, if your car breaks down or you get stuck in traffic, you need a heavy-duty sleeping bag or parka in the trunk.
- Check the Webcams: Use the NPS Yosemite webcams to see if the Valley is under a "cloud sea" or if the granite is actually clear.
The next 10 days are shaping up to be a "dry winter" stretch, which is perfect for photography and clear-sky stargazing, as long as you can handle the bite in the air. Just stay flexible. In Yosemite, the mountains always have the final say.
