You're planning a trip to the Mouse House, or maybe just a weekend getaway to catch a game at Angel Stadium, and you check the weather. It’s January. You expect "winter," right? But then you see it: 81°F. Wait, what? If you are looking at the anaheim ca 14 day forecast right now, specifically for mid-January 2026, you're likely seeing a heatwave that feels more like a July afternoon in some parts of the country.
It’s weird. Honestly, it’s kinda confusing for out-of-towners.
Right now, Anaheim is locked in a classic Santa Ana wind pattern. According to the latest National Weather Service discussions from the Los Angeles/Oxnard office, a high-pressure system has settled over the Great Basin, pushing dry, hot air from the deserts toward the coast. This isn't your standard "sunny California" day; it's a localized atmospheric phenomenon that turns the typical 68-degree January average into a bona fide scorcher.
Breaking Down the Anaheim CA 14 Day Forecast
If you’re looking at the numbers from today, January 15, through the end of the month, the trend is basically a slow slide from "unseasonably hot" back to "standard mild."
For the next few days, specifically through Saturday, January 17, expect highs to hover between 78°F and 81°F. The humidity is incredibly low—we’re talking 28% to 34%. Your skin will feel it. You'll need more water than you think. By Sunday and Monday (January 18–19), the ridge starts to break down. We see a shift to more cloud cover, with highs dropping into the mid-70s.
Then comes the "real" January.
By next Thursday, January 22, the marine layer—that thick blanket of Pacific fog—starts pushing back inland. Highs will likely plummet to 67°F. That’s a 14-degree swing in less than a week. It’s why locals carry a hoodie even when it’s 80 degrees at noon. Once that sun dips behind the Santa Ana Mountains, the desert air loses its heat instantly. Lows will stay consistent near 51°F to 53°F, which feels downright biting if you're standing in a 90-minute line for Space Mountain.

What the History Books Say vs. Reality
Statistically, January is supposed to be one of Anaheim’s wettest months. Data from the Western Regional Climate Center shows an average of about 3.34 inches of rain for the month. But 2026 is proving to be a dry one so far. The current forecast shows a measly 5% to 10% chance of rain through the 24th.
Don't let that fool you into a false sense of security.
In 2017, Anaheim got hammered with nearly 7 inches of rain in January. It happens in bursts. While the current 14-day outlook is dry, the GFS deterministic models are hinting at an upper-level low pressure system swirling near the coast toward the very end of the month. If that shifts, those "sunny" icons on your weather app will turn into "thunderstorms" faster than you can buy a $12 Disney poncho.
The Microclimate Trap
Anaheim has a specific "bowl" geography. It’s far enough from the ocean (about 15 miles) that it doesn't always get the cooling sea breeze until late afternoon, but it’s close enough to get "trapped" moisture.
- Morning (6 AM - 10 AM): Often crisp, sometimes foggy.
- Midday (11 AM - 3 PM): Intense UV rays. Even at 75°F, the California sun hits different.
- Evening (4 PM - Sunset): The "Thermal Transition." The wind shifts.
- Night: Rapid cooling.
If you're visiting Disneyland, this is the part that ruins vacations. You see 80 degrees on the anaheim ca 14 day forecast and pack shorts. Then 6:00 PM hits, the wind kicks up, and you’re suddenly spending $80 on a souvenir sweatshirt because you're shivering.
Strategy for the Current Forecast
Since we are looking at a cooling trend followed by potential volatility, your packing list needs to be tactical. Forget the heavy coats. Focus on the "puffer vest" or "light flannel" layer.
The Santa Ana winds currently blowing mean the air is dusty and dry. If you have asthma or sensitive sinuses, the air quality during these "warm" January days can be a bit rough. The wind gusts, particularly near the 57 and 91 freeway interchange, can hit 25 mph this week.
Keep an eye on the transition around Wednesday, January 21. That is the pivot point where the "Desert Summer" ends and the "California Winter" returns.
Actionable Insights for Your Trip
- Monitor the Dew Point: If you see the humidity climbing above 50% in the forecast next week, the marine layer is returning. Expect "Gray-neuary" mornings where the sun doesn't pop out until 1 PM.
- Sunscreen is Non-Negotiable: The UV index is hitting 3 or 4 even on "cool" days. Because the air is cool, you won't feel yourself burning.
- Hydrate for the Winds: Santa Ana winds strip moisture from your body. If the forecast shows "Northeast winds," double your water intake.
- Check the Ducks/Angels Schedule: If you're heading to the Honda Center, remember that the "pavement heat" in the parking lot will stay warm, but the breeze off the Santa Ana River trail nearby makes the walk to the entrance much colder than the "High" temperature suggests.
The 14-day window shows a city in transition. Enjoy the 80-degree peaks while they last, but keep the umbrella and the hoodie in the trunk for the inevitable return to the 60s next week.
