If you’re staring at the Santa Barbara weather 10 days outlook right now, you’re probably either thrilled or slightly annoyed. It's Sunday, January 18, 2026, and the American Riviera is doing that thing where it acts like three different seasons in a single week.
Honestly, it’s kinda weird. We’ve got this weird tug-of-war happening between a fading La Niña and some surprisingly warm highs. Most people assume January in Santa Barbara means "bring a raincoat and stay inside," but that’s not really the vibe this year.
Right now, it’s actually a pretty solid 68°F outside. If you’re standing in the sun, it feels more like 76°F. But don't let that fool you into thinking it's a beach day for everyone. The water is freezing, and the wind is coming off the southwest at about 3 mph, which is just enough to remind you it's still winter.
The 10-Day Reality Check
Most of the "big" weather sites will give you a generic sunny icon and call it a day. But if you look at the actual numbers for the next 10 days, things get interesting. We’re moving from "T-shirt weather" to "definitely need a heavy sweater" in a matter of 72 hours.
Tomorrow, Monday, January 19, is looking like the peak of the week. We’re talking a high of 65°F and pure, unadulterated sun. It’s perfect for a hike up Inspiration Point or just walking State Street without breaking a sweat. Lows will dip to 53°F at night, so if you're out late, you'll need a jacket.

By Tuesday, January 20, we climb back up to 67°F, but the clouds start rolling in. This is the transition phase. Enjoy the dry air while you can because by Wednesday, the humidity starts to climb.
When the Rain Actually Hits
People always ask me if it's going to pour. For the next few days, the answer is "not really." We’re seeing a persistent 10% chance of rain from Sunday through Wednesday. It’s basically just enough to make your car look dirty but not enough to cancel your outdoor dinner reservations at Loquita.
The real shift happens on Thursday, January 22.
Temperatures drop to 60°F, and that rain chance jumps to 35% at night. By Friday, January 23, we’re looking at a high of only 58°F. That’s the coldest day in the current 10-day window. If you’re visiting, this is your museum day. Or your "sit in a coffee shop in Montecito and pretend you're writing a screenplay" day.

The Weird Science of Santa Barbara’s Winter
There is a lot of talk about the 2026 La Niña. Normally, La Niña means a dry winter for Southern California. But as any local can tell you, Santa Barbara doesn't always follow the rules. This winter has been "relentless" with storms back in December and early January.
Because of all that previous rain, Goleta Beach County Park is actually partially closing starting January 26, 2026. They have to move a massive amount of sediment that washed down from the slough. It’s a huge operation involving the Santa Barbara Airport area and Old Town Goleta.
So, if you were planning a long walk on Goleta Beach next week, you might want to pivot to Hendry’s (Arroyo Burro) instead. The sediment transport is a necessary evil to protect the park from future wave impacts, but it’s definitely not the scenic "10-day forecast" view most tourists expect.
What to Actually Pack
If you’re looking at the Santa Barbara weather 10 days stretch and trying to pack a suitcase, listen up. You need layers. I know that’s a cliché, but it’s a cliché for a reason here.

Early in the week (Jan 18-21):
- Light linens or cottons for the daytime.
- A medium jacket for when the sun drops at 5:15 PM.
- Polarized sunglasses (the winter sun reflects off the ocean at a brutal angle).
Late in the week (Jan 22-27):
- A waterproof shell.
- Real shoes (not just flip-flops). The humidity will be hitting 81% by Friday, and everything feels damp.
- A heavy fleece or wool sweater. 50°F at night in Santa Barbara feels way colder than 50 degrees in a dry climate like Denver.
The Long-Range Outlook
Looking toward the end of the month, things start to stabilize. Saturday, January 24 through Tuesday, January 27 shows a string of partly sunny days with highs hovering right around 59°F to 63°F.
The UV index stays pretty low, around a 2 or 3, so you won't fry, but you should still wear sunscreen if you're out on the water. The wind stays mild, mostly under 6 mph, which makes the harbor look like glass—perfect for kayaking if you don't mind the chill.
Honestly, the biggest misconception about the Santa Barbara weather 10 days outlook is that it's "static." It's not. One hour you're in a fog bank that feels like a horror movie, and the next, the sun breaks through and it's 70 degrees.
Practical Next Steps
If you’re heading out this week, check the National Weather Service station in Oxnard for the most granular updates, especially regarding the fog. If you're planning on visiting Goleta Beach, check the County Parks website (sbparks.org) before you go to see which sections are cordoned off for the sediment work. Lastly, if you're hitting the trails after the light rain on Thursday, be prepared for some mud—the clay in our soil doesn't drain fast, and it will ruin your fancy white sneakers in about three seconds.
