Ever stood in the middle of a theme park at 10:00 AM wondering why you’re sweating in a sweatshirt you desperately needed two hours ago? That’s basically the Anaheim experience in a nutshell. If you're tracking anaheim ca weather hourly for a trip to the Mouse or a game at the Big A, you’ve probably noticed the numbers jump around like crazy.
It’s currently 65°F as of Friday night, January 16, 2026.
Honestly, the "average" temperature doesn't tell you much here. Earlier today, we hit a high of 85°F under a blazing sun, but the low tonight is dipping all the way down to 46°F. That’s a nearly 40-degree swing. If you aren't checking the hour-by-hour breakdown, you're gonna have a bad time.
Why the Hourly Swings are So Brutal
Anaheim sits in this weird geographic sweet spot—or sour spot, depending on your outfit choice. It’s far enough from the coast that the Pacific breeze doesn’t always cool it down during the day, but close enough that the marine layer can roll in and turn things chilly the second the sun drops.

Today, the wind is coming from the northeast at 4 mph, and the humidity is sitting at a crisp 28%. That dry air is a classic Southern California winter staple. It means when the sun is out, it feels way hotter than the thermometer says. When it's gone? The heat vanishes instantly.
Anaheim CA Weather Hourly: A Deep Dive into the Specifics
If you’re looking at the forecast for the rest of tonight and into tomorrow, here is the breakdown of what's actually happening on the ground:
- Tonight (Late Friday): We are looking at mostly cloudy skies. The precipitation chance is low at 10%, but don't expect a downpour. It's more of a damp chill.
- Winds: Light but steady from the northeast.
- UV Index: It's 0 right now (obviously, it's night), but even in January, Anaheim’s midday UV index can sneak up on you.
Most people see "85 degrees" in the forecast and pack shorts. Then 7:00 PM hits, the temperature drops to the 60s, and they’re part of the $80 Disney sweatshirt economy. Don't be that person.

The Santa Ana Factor
We have to talk about the winds. When you see anaheim ca weather hourly reports showing northeast winds and plummeting humidity (like the 28% we're seeing now), you're often feeling the tail end of a Santa Ana event. These aren't your typical breezes. They are "katabatic" winds—meaning they compress and heat up as they drop down from the high deserts through the mountain passes.
This explains why it's 85°F in mid-January. It's not "global warming" every single time; sometimes it's just the Great Basin dumping its air into our backyard. It makes the air feel "electric" and bone-dry. You'll feel it in your skin and see it in the "beautifully clear" skies that usually accompany these events.
How to Actually Plan Your Day
The smart move is to treat Anaheim like three different climates.

From 6:00 AM to 9:00 AM, it's basically the Pacific Northwest. You want layers. From 11:00 AM to 4:00 PM, it's the desert. You want sunscreen and water. After 6:00 PM, the temperature falls off a cliff.
According to the latest data from the first weather card today, the humidity is expected to hover around 35% for the daily average, but the hourly shifts are where the real story lives. With a 10% chance of rain tonight, it’s unlikely you’ll need an umbrella, but the cloud cover will keep that 46-degree low from feeling even more piercing.
Actionable Insights for Your Visit
- Check the Dew Point, Not Just Temp: If the dew point is low (which it is today), the temperature will drop much faster after sunset.
- Hydrate Early: In 28% humidity, you lose moisture just by breathing. If you wait until you're thirsty, you're already behind.
- The 4:00 PM Rule: This is the pivot point. Around 4:00 PM, the "daytime" weather ends. That is when you should head back to the car or hotel to grab that jacket you thought you wouldn't need.
Keep a close eye on the anaheim ca weather hourly updates specifically for wind direction. Northeast winds mean dry and warm; West/Southwest winds mean the ocean is taking over, bringing cooler air and higher humidity.
Stay adaptable, dress in layers, and respect the Santa Anas.
