So, you’re looking at the anaheim weather 10 day forecast and wondering if you should pack a parka or a tank top. Typical California dilemma. Most people assume Southern California is just a perpetual heatwave, but honestly? January in Anaheim is a bit of a wildcard. If you’re coming from the Midwest, you’ll probably think it's summer. If you’re a local, you’re currently digging through your closet for a puffer jacket.
Right now, we are seeing some unseasonably warm numbers. Today, Wednesday, January 14, 2026, it is basically hitting 83°F. That is a solid 15 degrees above the historical average of 68°F for this time of year. If you’re at Disneyland right now, you’re likely sweating in the Space Mountain queue. But don't get too comfortable with the heat—the next ten days are going to be a slow slide back down to reality.
Breaking Down the Anaheim Weather 10 Day Forecast
The immediate outlook is bright. Literally. For Thursday, January 15, we are looking at another scorcher with a high of 83°F and a low of 55°F. It’s that weird desert-adjacent climate where the sun feels like a laser during the day, but the second it dips behind the Anaheim hills, you’ll be shivering.
By Friday, the "cool down" starts, though 77°F is still plenty warm. The real shift happens over the weekend. Saturday and Sunday (Jan 17-18) will see highs hover around 76°F or 77°F. You’ll start to see some "mostly cloudy" labels on your weather app. Clouds in Anaheim usually mean one of two things: a lovely break from the glare, or the "June Gloom" that accidentally showed up five months early.

The Mid-Week Shift
As we head into next week, the anaheim weather 10 day forecast shows a steady decline:
- Monday, Jan 19: Mostly sunny, high of 74°F. Perfect walking weather.
- Tuesday, Jan 20: Partly sunny, dipping to 73°F.
- Wednesday, Jan 21: Solid sunshine, 70°F. This is the sweet spot.
- Thursday, Jan 22: This is where things get interesting. Clouds roll in, humidity jumps to 62%, and we might see some stray showers. High of 65°F.
By the time we hit Friday, January 23, and Saturday, January 24, the "winter" part of Anaheim finally wakes up. We’re looking at highs of 62°F to 65°F. If you’re from out of state, that sounds nice. But with the humidity climbing toward 68%, it’s a damp kind of cold that gets into your bones.
Why the "Average" Forecast is a Lie
If you look up the average temperature for Anaheim in January, you’ll see 68°F. That number is a mathematical ghost. It rarely actually stays at 68. Instead, you get these wild swings where it’s 85 one day because of the Santa Ana winds and 58 the next because a Pacific storm decided to park itself over Orange County.
The Santa Anas are the reason for this current heat spike. These are dry, warm winds that blow in from the Great Basin. They clear out the smog, make the air feel crisp, and send the fire risk skyrocketing. But as those winds die down, the marine layer—that thick blanket of Pacific fog—often rushes back in to claim the territory.
Humidity and the "RealFeel"
Humidity in Anaheim is weirdly low right now, around 31% to 36%. This makes the 83-degree heat feel "dry." You won't feel like you're walking through soup like you would in Orlando. However, toward the end of the 10-day window, that humidity doubles. A 62°F day with high humidity and no sun feels significantly colder than a 55°F night with clear skies.
Packing for the 10-Day Outlook
Don't be the person who buys a $70 Mickey Mouse sweatshirt because you didn't check the lows. Even on an 83°F day, the temperature drops to 53°F at night. That is a 30-degree swing.
Layers aren't just a suggestion; they are a survival strategy. Start with a t-shirt for the noon sun. Bring a light hoodie for the 4:00 PM transition. Keep a heavier jacket in your car or a locker for after the fireworks. If you’re planning to be in the area around January 22 or 23, definitely pack a light rain shell. The chance of precipitation is currently sitting around 15% to 20%, which isn't a washout, but enough to make you miserable if you're unprepared.

Beyond the Thermometer: Sunlight and UV
Even though it’s winter, the UV index is hitting 2 or 3. It sounds low, but if you’re out for 10 hours at a theme park or walking around the Anaheim Packing District, you will get a "January burn."
Daylight is also limited. The sun is setting around 5:05 PM right now. This is a huge factor for your 10-day planning. Once that sun goes down, the heat vanishes instantly. If you have dinner reservations outdoors for next Tuesday or Wednesday, make sure they have space heaters, or better yet, grab a table inside.
Actionable Weather Prep for Your Trip
- Check the hourly, not the daily: A high of 80 doesn't mean it's 80 at 10:00 AM. It’s likely only 80 for about two hours (2:00 PM to 4:00 PM).
- Hydrate more than you think: The Santa Ana winds are incredibly drying. You’ll get a headache before you realize you're thirsty.
- Footwear matters: If you're here for the later part of the forecast (Jan 22-24), avoid mesh sneakers that soak up water. Stick to something water-resistant.
- The "Shade Rule": In Anaheim, the difference between standing in the sun and standing in the shade can feel like 10 degrees. If you’re hot, find a building shadow; if you’re cold, move ten feet into the sunlight.
The anaheim weather 10 day forecast is currently telling a story of two seasons. We’re starting with a late-summer encore and finishing with a classic, damp Southern California winter. Keep a close eye on Thursday, January 22—that’s the pivot point. If that low-pressure system moves faster, your dry vacation might get a little splashy a day early.
Stay flexible, watch the wind speeds, and maybe keep a spare pair of socks in your bag. You’ll thank yourself when the sun goes down.
