Honestly, most people think Southern California is a permanent summer loop. They pack flip-flops for a January trip to Disneyland and end up dropping 80 bucks on a "spirit jersey" just to stop shivering by 6:00 PM. If you're looking at the weather 10 day Anaheim forecast right now, you’re seeing a classic California winter bait-and-switch.
We’re currently sitting in a weirdly warm pocket, but don't let that 79°F high today, Sunday, January 18, fool you into thinking the whole week is a sun-soaked dream. It's actually kind of a rollercoaster.
Right now, it's 60°F outside as I'm writing this (it's nighttime), with a northeast wind moving at about 6 mph. The air is dry—32% humidity—so it feels crisp. But the next ten days are basically a slow slide from "Wait, is it summer?" back down to "Okay, yeah, it's definitely January."
The Breakdown: Sun, Clouds, and That Sneaky Temperature Drop
If you’re heading to the parks or just hanging out in Orange County this week, Monday and Tuesday are your peak "sunscreen and shades" days. We’re talking highs of 76°F and 75°F. It’s perfect. It’s the kind of weather that makes people move here and then complain when it hits 65°F.
But check this out: by Wednesday, the vibe shifts. The clouds start rolling in. We go from "sunny" to "mostly cloudy," and the high drops to 71°F. By Thursday, we’re at 66°F. That’s a 13-degree swing in just a few days.
Here is the thing about Anaheim weather that the apps don't emphasize enough: the lows. Every single night for the next ten days, the temperature is going to bottom out between 51°F and 53°F. When that sun goes down behind the Matterhorn, the heat radiates off the pavement fast. If you’re standing in a 90-minute line for Rise of the Resistance in a t-shirt when it’s 52°F, you’re going to have a bad time.
What to Expect Day-by-Day (The Realistic Version)
- Sunday (Today): Topping out at 79°F. It’s the hottest day of the stretch. Clear skies tonight.
- Monday & Tuesday: Still beautiful. Highs in the mid-70s. UV index is around 3, so you can still get a burn if you're out all day.
- Wednesday through Friday: The "Gray Period." Highs tumble into the mid-60s. We’re looking at 65°F to 66°F by Friday. It’ll feel much cooler because the humidity jumps from 30% up to 61%.
- The Weekend Outlook: Saturday, January 24, brings the only real threat of rain in the forecast—a 20% chance of light rain during the night. Highs stay chilly at 66°F.
- The Tail End: Monday and Tuesday (Jan 26-27) show a slight rebound to 68°F and 71°F.
Why This Specific Forecast Matters
There’s a lot of talk about the "snow drought" in the West right now. While Northern California is getting hit with atmospheric rivers, Southern California is mostly just getting the leftover clouds and a bit of a breeze.
Historically, January is one of Anaheim’s rainiest months, but 2026 is playing it pretty dry so far. Usually, we'd expect about 2.5 inches of rain this month, but the current weather 10 day Anaheim data shows nothing more than a few sprinkles on Saturday night. It's great for tourists, but kinda worrisome for the local water table.
I’ve lived through Santa Ana wind events where it hits 90°F in January, and "atmospheric rivers" where the 5 freeway turns into a river. This ten-day stretch is neither of those extremes. It’s just... standard. Mild. A little moody toward the end.
How to Actually Pack for This
Don't be the person who brings a heavy parka. You'll look ridiculous and be sweating by noon. But also, don't just bring shorts.
The Layering Strategy:
Basically, you need a "three-stage" outfit.
- Morning (6 AM - 10 AM): You need a light jacket or a hoodie. It’s 52°F.
- Midday (11 AM - 4 PM): This is your t-shirt window. It'll be 70°F+.
- Evening (5 PM - Late): The sun sets around 5:10 PM. The temperature drops instantly. Back to the hoodie.
If you're doing a Disney day, rent a locker. Throw your sweatshirts in there at 11 AM and go grab them at 5 PM. It's the best 15 dollars you'll spend all trip.
Actionable Tips for Your Anaheim Trip
If you’re looking at the weather 10 day Anaheim forecast and planning your life, here are three things you should actually do:

- Prioritize outdoor stuff early: If you want that perfect pool day or a trip to Huntington Beach, do it Sunday through Tuesday. After that, the cloud cover makes the "real feel" much lower than 66°F.
- Hydrate more than you think: The humidity is super low (30-38%) for the first half of the week. You won't feel sweaty, but you'll get dehydrated and end up with a headache by 3 PM.
- Watch the Saturday night rain: It’s only a 20% chance, but in SoCal, 20% usually means a mist that makes the roads incredibly slick because of all the built-up oil. If you’re driving, give yourself extra space.
The bottom line? It’s a great week to be in Anaheim, just don't trust the afternoon sun to stay all night. Pack the layers, keep an eye on that Saturday cloud cover, and enjoy the lack of 90-degree heat.
