It is looking like a weird one tomorrow. If you’re living in the Santa Clarita Valley, you probably woke up today feeling that familiar dry bite in the air. Tomorrow, Wednesday, January 14, 2026, is basically going to be a repeat of that, but cranked up a few notches. We are looking at a peak high of 77°F.
For mid-January, that’s honestly pretty warm. It’s about 14 degrees above the historical average for this time of year. Usually, we’re hovering around 63°F, maybe wearing a light jacket all day, but tomorrow is shaping up to be "shorts and a t-shirt" weather by noon. But don't let the sun fool you. There is a catch, and it’s a gusty one.
Santa Clarita weather tomorrow and the persistent Wind Advisory
The National Weather Service has kept a Wind Advisory in effect for the Santa Clarita Valley until 2 PM tomorrow. We’re talking about northeast winds sustaining between 15 to 25 mph. That’s enough to make your patio furniture migrate into your neighbor’s yard if you haven't tied it down yet.
What’s more concerning are the gusts. We could see hits of up to 40 mph, especially if you’re up in the hills or near the canyons like Bouquet or San Francisquito. This isn't just a "bad hair day" kind of wind. These Santa Ana-lite conditions are notorious for making high-profile vehicles—think trucks and SUVs—feel a bit sketchy on the 5 or the 14 freeways. If you're driving a top-heavy car, keep both hands on the wheel when you pass those open gaps in the hills.
The humidity is basically non-existent
One thing you’ll definitely notice tomorrow is how dry it feels. The humidity is expected to bottom out around 18% to 29%. That’s bone-dry.

Expect to be reaching for the lip balm and heavy-duty lotion. When the humidity drops this low in SCV, static electricity goes nuts. You'll probably get zapped every time you touch a door handle. More importantly, it means the fire risk is elevated. Even though we had some rain earlier in the month, these dry winds suck the moisture right back out of the brush.
Breaking down the hour-by-hour vibe
Tomorrow morning is going to start off crisp. Around 7:00 AM, when the sun is just peeking over the mountains, it’ll be about 55°F. It’s that classic Southern California desert-adjacent transition where you need a parka for the school drop-off and then you're sweating by lunchtime.
- 9:00 AM: The temperature jumps quickly to 62°F. The wind will be active.
- 12:00 PM: We hit the low 70s. This is the peak of the wind activity.
- 2:00 PM: The high of 77°F settles in. The Wind Advisory officially expires, though it'll likely stay breezy.
- 5:00 PM: Sunset hits at 5:06 PM. The temperature starts its rapid descent back into the 60s.
It’s a clear-sky day. Total sunshine. Zero percent chance of rain. You’ve basically got a 10-hour window of pure, unadulterated UV rays. The UV index is a 3, which is "moderate," but since the air is so clear and the humidity is low, that sun can feel a lot hotter on your skin than the thermometer says.
What to wear for the SCV climate tomorrow
Dressing for Santa Clarita weather tomorrow is all about the "onion method." Layers.

Start with a light base layer because 77°F in the sun feels like 82°F. But since you’ll be dealing with 25 mph wind gusts, a light windbreaker or a denim jacket is a must. If you’re planning on being out after 6 PM, keep a real sweater in the car. Once that sun goes behind the Magic Mountain horizon, the temperature drops like a rock. We’re heading toward a night-time low of 55°F, which feels a lot colder when you've spent the afternoon in the 70s.
Why is it so warm right now?
Usually, January in Santa Clarita is the month of "gray." We get about 41% cloud cover on average. But 2026 has been leaning into these high-pressure ridges. According to the latest data from the National Weather Service and local stations like KBUR, we’re seeing a stronger-than-usual offshore flow. This "Santa Ana" effect compresses the air as it moves down the mountains, heating it up and drying it out. It’s why we’re hitting summer-lite temperatures while the rest of the country is dealing with actual winter.
Real-world impacts you should prepare for
If you have a commute tomorrow, specifically heading south toward the San Fernando Valley, expect the Newhall Pass to be a bit of a wind tunnel. The gusts are often strongest right at the 5/14 interchange.
Also, check your yard tonight. If you have umbrellas up or light plastic bins outside, move them into the garage. I’ve seen enough "free" trampolines flying across Soledad Canyon Road to know that a 40 mph gust doesn't play around.

For the gardeners: your plants are going to be thirsty. This kind of dry, windy heat is a nightmare for citrus trees and new landscaping. Give them a good soak tonight or early tomorrow morning before the wind really starts to pick up.
Looking ahead at the week
Tomorrow is actually the peak of this mini-heatwave. By Thursday and Friday, we’re staying in the mid-70s, but the wind should calm down significantly. We won't see a real "cool down" until the middle of next week when a potential system might bring us back into the 60s. For now, enjoy the "winter" heat, but keep an eye on those power lines if the wind gets extra rowdy.
Your Wednesday checklist
- Hydrate: You'll lose more moisture than you think in 20% humidity.
- Secure the yard: Don't let your trash cans become projectiles.
- Drive heavy: If you have a choice of cars, take the heavier one for better stability in the wind.
- Sunscreen: Even in January, 77°F and zero clouds will give you a burn if you're out at Central Park all afternoon.
Check the local SCV news feeds or the NWS Los Angeles social accounts tomorrow morning around 6 AM to see if they’ve extended the Wind Advisory. Sometimes these offshore events linger longer than expected if the pressure gradient doesn't relax on schedule.
