Honestly, if you’re looking at Big Sur weather today, you’ve probably seen the headlines about the "unbroken" Highway 1. It’s a huge deal. After years of slides and road crews playing a giant game of Tetris with boulders, the road finally reopened end-to-end on January 14, 2026. Governor Newsom even did the whole press circuit for it. But here’s the thing: just because the road is open doesn’t mean the weather is going to play nice for your Instagram shots.
The current situation on the cliffs
Right now, Big Sur is sitting at a comfortable 68°F, though it actually feels like 72°F thanks to the way the sun hits those steep Santa Lucia slopes. It’s mostly cloudy, which—if you’re a photographer—is actually better than a clear sky because you don't get those harsh, blown-out shadows on the surf. The wind is basically nonexistent, just a 2 mph breeze coming off the West.
You’ve gotta be careful with the humidity, though. It’s at 51%, which isn't "sticky" by East Coast standards, but it’s enough to make the air feel heavy.
Highs, lows, and that 10% chance
The high for today is pegged at 71°F, while it’ll dip down to 62°F tonight. Usually, January in Big Sur is the "storm season" where you’d expect to be dodging mudslides. But today? We’re looking at a 10% chance of rain. That’s basically the meteorologist’s way of saying "you might see a misting for five minutes, or nothing at all."

The UV index is low (around 1), so you won't fry, but don't let the clouds fool you—the reflection off the ocean can still give you a weird "fog burn" if you’re out hiking the Ewoldsen Trail all afternoon.
Why the "reopening" changes how you watch the weather
Since the Regent's Slide area finally cleared up a few days ago, the way we talk about Big Sur weather today has shifted. For the last two years, a 10% rain chance meant "will the road stay open?" Now, it’s more about "will I actually see Bixby Bridge through the fog?"
The air quality is a bit of a talking point right now too. There’s a Spare the Air alert active through Sunday for the broader region. High pressure is trapping air near the ground. While Big Sur usually gets that fresh Pacific scrub, you might notice a bit of a haze if you’re looking inland toward the valley.

What to actually wear (The "Big Sur Layering" Law)
If you're heading out right now, do not—I repeat, do not—just wear a t-shirt because it says 71 degrees.
- The Base: Standard tee is fine.
- The Middle: A light flannel or a hoodie.
- The Shell: Bring something wind-resistant. Even with a 2 mph wind at the coast, if you climb up toward the ridge, that Pacific air accelerates.
Basically, the temperature can swing 10 degrees just by driving three miles inland or gaining 500 feet of elevation.
The "Regent's Slide" factor
Even though the road is officially "open," Caltrans is still babying that 6.8-mile stretch near Regent's Slide. They’ve got sensors drilled 60 feet deep into the mountain. If that 10% chance of rain turns into a localized downpour—which happens in these microclimates—they might hit the panic button and do a temporary closure for safety. It’s the reality of living on a crumbling edge of the continent.

Most people think Big Sur weather is one big blanket. It's not. It's a patchwork. You can have a "mostly cloudy" report at the Big Sur River Inn while it’s dumping rain at Julia Pfeiffer Burns State Park.
Actionable steps for your trip today
First off, check the Caltrans QuickMap before you lose cell service near Carmel. Once you’re in the "Big Sur shadow," your GPS is basically a paperweight.
Second, if you’re planning on hitting McWay Falls, do it now while the wind is low. High winds can turn that iconic waterfall into a horizontal spray that looks less like a postcard and more like a broken fire hydrant.
Lastly, keep an eye on the south wind picking up to 6 mph later. It’s not much, but it’s often the precursor to more clouds rolling in for the evening. If you want that sunset, find your spot by 4:00 PM. The sun drops behind the horizon fast, and the "blue hour" in Big Sur is short but legendary.
Drive slow. The road is fresh, the curves are still tight, and the views are finally, finally back in one piece.
