If you’re heading to the Land of the Mouse or just trying to survive the morning commute, listen up. The weather for Anaheim California tomorrow, Thursday, January 15, 2026, is basically going to be a giant game of "how many layers can I take off before noon?"
We aren't talking about the typical "gloomy January" people warn you about.
Honestly, it’s looking spectacular. But if you walk out the door in a tank top at 7:00 AM, you’re going to regret every life choice you’ve ever made.
The Highs, the Lows, and Everything Between
Tomorrow is going to be a bright, sun-drenched day. Expect a high of 83°F. That is significantly warmer than the historical average of 68°F for this time of year. While the rest of the country is probably scraping ice off their windshields, Anaheim is going to feel more like a late spring afternoon.
But here is the catch.

The low is dropping down to 55°F.
That's a nearly 30-degree swing. If you've spent any time in Southern California, you know this is the "desert effect" in full swing. It’s dry, it’s crisp, and it’s a bit unpredictable for your wardrobe.
The humidity is hovering at a very comfortable 31%. Basically, you won't be sweating through your shirt, but your skin might feel a little parched. Bring some lip balm. Trust me.
Morning, Noon, and Night: A Timeline
- 7:00 AM - 9:00 AM: It’s brisk. We’re talking light jacket or a thick hoodie weather. The sun is up, but it hasn't started cooking the pavement yet.
- 11:00 AM - 3:00 PM: This is the peak. This is when that 83°F hits, and since there’s 0% chance of rain, there are no clouds to hide under. The UV index is a 2, which sounds low, but if you’re standing in a 90-minute line for Space Mountain, it adds up.
- 5:00 PM onwards: As soon as the sun dips behind the Santa Ana Mountains, the temperature will plummet.
What Most People Get Wrong About January in Anaheim
A lot of tourists check the "average" and think they’re in for 65-degree weather.

They pack one sweater and a pair of jeans.
Then a Santa Ana wind event or a random high-pressure ridge like this one kicks in, and suddenly it’s 80 degrees. They end up buying $75 Disney-themed t-shirts just to stop overheating. Conversely, locals know that "California cold" is a real thing. 55 degrees with a 7 mph breeze feels much chillier than you'd expect because the air is so dry.
The Wind Factor
The wind is coming from the southeast at about 7 mph. It’s not a gale, but it’s enough to make a shadow feel significantly colder than the sun. If you’re planning on being outdoors near the Anaheim Packing District or the Platinum Triangle, stick to the sunny side of the street.
Actionable Tips for Tomorrow
Since we know exactly what’s coming, let's talk strategy.

First off, wear a base layer that you actually like. Don’t wear a beat-up undershirt thinking you’ll keep your sweater on all day. By 1:00 PM, that sweater is going in a locker or being tied around your waist.
Hydration is actually more important tomorrow than on a humid day. Because the air is dry (that 31% humidity we mentioned), your sweat evaporates instantly. You won't feel "gross," so you might forget to drink water. Don't make that mistake.
If you're heading to a theme park, remember that the concrete acts like a heat sink. It’ll feel a few degrees warmer in the middle of a crowd than the official forecast says.
Your Tomorrow Survival Kit:
- Sunglasses (it’s going to be bright).
- A light, packable windbreaker or denim jacket.
- Sunscreen (even with a low UV index, 83 degrees means direct sun exposure).
- A reusable water bottle.
The weather for Anaheim California tomorrow is essentially a gift. No rain, clear skies, and warm enough to enjoy an outdoor lunch at the Packing House. Just be ready for that sunset temperature drop, and you’ll be golden.
