Honestly, people think Arizona is just a non-stop furnace, but if you’re looking at the glendale az 10 day forecast right now, you’re in for a bit of a shock. It’s January 18, 2026, and while the rest of the country is probably shoveling snow, we’re out here dealing with what locals call "the big chill"—which, okay, is basically 70 degrees, but still.
Current conditions are actually pretty sweet. Right now, it’s a crisp 53°F outside under a perfectly clear night sky. The wind is barely a whisper, coming out of the northeast at about 6 mph. If you’re heading out early, you’ll definitely want a hoodie. Or maybe two.
The Reality of the Glendale AZ 10 Day Forecast
Here’s the thing about West Valley weather: it’s predictable until it isn't. Most people assume they’ll just need shorts and a tee, but the next week and a half has some mood swings planned.
Today, Sunday, we’re looking at a high of 75°F. It’s gonna be partly sunny and honestly, about as perfect as it gets for a walk around Sahuaro Ranch Park. But don’t let that afternoon sun fool you. The low tonight hits 47°F. That’s a nearly 30-degree drop. If you’re at the Westgate Entertainment District for dinner, you’ll be shivering by the time you hit the parking lot if you didn't bring a jacket.
Monday keeps that energy with a high of 74°F, though it’ll be mostly cloudy. By Tuesday and Wednesday, the clouds clear out, and we’re back to pure Arizona gold—sunny skies and highs between 71°F and 73°F.

What to Actually Do With This Information
If you’re planning your week, keep Wednesday and Thursday on your radar. There’s a "Coffee with a Cop" event at the Starbucks on Glendale Ave on the 21st, and the weather will be a crisp, sunny 71°F. Perfect for an iced latte, or maybe a hot one if the 4 mph breeze feels too nippy.
Thursday is the "Chalk the Walk" event at the Main Library. It’s going to be a bit cooler, hitting a high of 69°F under a blanket of clouds. If you’re taking the kids, they’ll want long sleeves since that sun won't be peeking through much.
Saturday the 24th is the big "Country Music Night" downtown. Honestly, with that 35% chance of rain at night, you might want to swap the suede boots for something that can handle a drizzle. The high is only 69°F, and the low stays at 50°F, so it’ll be a damp, chilly night for line dancing.
Basically, the glendale az 10 day forecast is telling you to layer up. The daytime is beautiful, but those desert nights don't play around.
Actionable Tips for the Week
Check your irrigation timers if you have a yard; with the rain expected Saturday and Sunday, you might be able to skip a cycle. Also, if you’re heading to the Barrett-Jackson auction over in Scottsdale or staying local for the Foothills Library craft swap on the 25th, pack a light windbreaker. The humidity jump from 21% to 61% over the weekend is going to make the air feel much heavier than we're used to.

Stay hydrated even though it's cool—the UV index is still hitting a 3 most days, which is sneaky. You can still get a burn at 70 degrees if you aren't careful. Keep an eye on that Saturday rain chance as we get closer, but otherwise, enjoy the "winter" while it lasts.
