You're looking at the 10 day forecast Lake Havasu City AZ and thinking it looks pretty standard for January. Sunny. Clear skies. Maybe a light breeze off the water. But honestly, if you’ve spent any real time in the Mohave Desert during the winter, you know the numbers on your phone screen only tell about half the story.
Right now, we are looking at a stretch of weather that's basically a dream for anyone escaping a "real" winter back east. We're seeing daytime highs hovering consistently between 71°F and 78°F through the next week. It’s that sweet spot where you don't even need a jacket at noon, but you’ll definitely be reaching for a hoodie the second the sun dips behind the Chemehuevi Mountains.
Why the Desert Chills Faster Than You Think
Most people see "sunny and 74" and pack shorts. Do that, and you’ll regret it by 5:30 PM. The air here is incredibly dry—humidity is sitting around 12% to 35%—which means there’s nothing to hold the heat once the sun goes down. We're looking at overnight lows in the low 50s and high 40s.
It’s a massive swing.

If you're planning to be out on a boat near Copper Canyon or grabbing a drink at the London Bridge Resort, that 20-degree drop feels like hitting a wall. The water temperature in Lake Havasu right now is a brisk 50°F. Even if the air is 75°F, that massive body of cold water acts like a natural air conditioner. If the wind kicks up—and the forecast shows north winds at 5 to 15 mph—you’re going to feel a bite that the "feels like" temperature doesn't always capture.
The 10 Day Forecast Lake Havasu City AZ Breakdown
Let's get into the weeds of what the next week and a half actually looks like. We aren't seeing much in the way of rain. There was a tiny bit of moisture at the start of the month, but the current outlook is bone-dry.
- Thursday, Jan 15 - Saturday, Jan 17: We are peaking early. Expect highs around 78°F today, dipping slightly to 73°F by Saturday. It’s perfect "t-shirt weather" for the Havasu 95 Speedway or just walking the Island Trail.
- Sunday, Jan 18 - Wednesday, Jan 21: Consistency is the name of the game here. Highs will stay locked in at 71°F to 73°F. You’ll see some "mostly sunny" labels, which basically means a few high cirrus clouds might drift through, but nothing that’s going to ruin your tan.
- Late Next Week (Jan 22 - Jan 24): A minor cooling trend is moving in. We’re looking at highs dropping into the upper 60s (around 67°F or 68°F). While that’s still gorgeous, the wind usually picks up right before these slight temperature drops.
If you’re coming for the Havasu Balloon Festival & Fair (which kicks off January 22), pay close attention to those morning winds. Hot air balloons are notoriously finicky. Even a 10 mph gust can ground the morning "mass ascension," so you’ll want to check the hourly wind speeds around 6:00 AM each day.

The "Dry Heat" Myth in Winter
Everyone talks about the dry heat in July when it's 115°F, but the dry cold is what catches visitors off guard in January.
Your skin will feel it first. Between the low humidity and the desert wind, you’ll be reaching for lotion and chapstick more than you expect. And hydration? You don't sweat the same way here. You lose moisture just through breathing in this dry air. Even though it's 72°F and beautiful, drink more water than you think you need.
Events and the Weather Connection
The weather directly dictates the vibe in Havasu. Since the 10 day forecast Lake Havasu City AZ looks so stable, the local event calendar is packed.

For instance, American Mile is playing at the Flying X Saloon on Friday night (Jan 16). Since it's an indoor venue, the 53°F low doesn't matter much—until you walk out to the parking lot. On the flip side, if you're hitting the Mudshark Brewery on the 24th for Zane Lamprey’s comedy tour, that's when the "cooling trend" hits. That 67°F high earlier in the day will feel like a distant memory once you’re standing outside in the 50°F night air.
The Lake Havasu City Aquatic Center is hosting a Garth Brooks tribute on the 19th. Even though it's an indoor facility, the walk from the parking lot in 52°F weather is exactly why you see locals wearing heavy North Face jackets while tourists are still in flip-flops. We've gone "thin-blooded," and honestly, you might too after a few days here.
Real Talk on Water Activities
Can you swim? Well, sure, if you’re a polar bear.
With water temps at 50°F, nobody is "leisurely" swimming in the lake right now. You’ll see some jet skiers in wetsuits and maybe some hardy paddleboarders, but the lake is mostly for cruising and fishing this time of year. The fishing is actually pretty decent for smallmouth bass if you know where the deeper ledges are, as the fish move a bit slower in the cold.
Actionable Tips for the Next 10 Days
- The 3-Layer Rule: Start with a base layer, add a flannel or light sweater, and keep a windbreaker in the car. You will likely use all three between 8:00 AM and 8:00 PM.
- Wind Watch: If you're hiking SARA Park, do it in the morning. The north winds often pick up in the afternoon, making the ridges a bit more "adventurous" than most people want.
- Sunscreen is Mandatory: Don't let the 70-degree temps fool you. The sun at this elevation and in this clear air is intense. You can still get a nasty burn sitting on a boat for four hours.
- Check the Balloon Festival Updates: If you're here for the balloons starting the 22nd, follow the official "Havasu Balloon Fest" social pages. They make the "Go/No-Go" calls for flights based on wind data that is much more specific than your standard weather app.
Basically, the next 10 days are looking like peak Arizona winter. It’s dry, it’s bright, and it’s predictably unpredictable once the sun goes down. Pack for two different climates—the one at noon and the one at midnight—and you’ll have a much better time.
