Denver is baking under sunny skies and a high near 98°F today, with a Heat Advisory in effect for the Denver Metro and I-25 Corridor from 10 AM Sunday through 9 PM Monday — so if you’re heading to Cheesman Park, Wash Park, or the Highline Canal trail, plan around the middle of the day.
Today’s Setup
The National Weather Service in Boulder says a broad upper ridge is parked over the Rockies, keeping the airmass dry and pushing mid-level temperatures up enough that today and Monday will be the two hottest days of the week. Winds stay light out of the north-northwest at 2 to 6 mph, and rain chances are essentially zero (1%) through the afternoon.
Heat Advisory Through Monday Night
What’s most notable, per the forecast discussion, isn’t just the daytime heat — it’s that overnight lows are only expected to drop into the low-to-mid 70s tonight and Monday night, which the Heat Risk outlook flags as a moderate-to-major impact on its own. If you don’t have great cooling at home, tonight’s a good night to lean on a portable window AC unit rather than waiting out the heat with fans alone.
Best Window To Be Outside
Mornings before 10 AM and evenings after 7 PM are your friend this week. Sunday and Monday afternoons in the mountains will see scattered storms develop, but the Denver plains stay dry both days — good news for outdoor plans downtown, though I-70 mountain travelers should watch for pop-up storms.
Rockies, Red Rocks & Ball Arena This Week
The Colorado Rockies host the Cincinnati Reds today at Coors Field, and it’s a hot, sunny one for first pitch — bring water and sunscreen if you’re tailgating. Grab a Colorado Rockies jersey or Colorado Rockies fitted cap before you head down, and check tickets on SeatGeek if you still need seats. Tonight also brings Maren Morris with the Colorado Symphony Orchestra at Red Rocks — dress light early, but a light layer won’t hurt after sunset. Monday, as the heat peaks near 100°F, Forrest Frank brings The Jesus Generation Tour to Ball Arena, which is indoors and a great heat-dodging option — look for a Forrest Frank t-shirt to grab on your way in.
What To Wear Or Bring
Light, breathable clothing, sunglasses, and constant hydration are the move both days. If you’re near water at Chatfield or Cherry Creek Reservoir, a Yeti hopper soft cooler keeps drinks cold in this heat.
Dinner Idea Tonight
This is textbook grilling weather — fire up burgers, steaks, or grilled chicken with corn on the cob while it’s still light out. An instant-read meat thermometer and a grill brush and scraper set make cleanup and doneness painless. Need ingredients? You can order groceries on Amazon and have everything for tonight’s dinner delivered to your door.
Next Few Days
Monday holds near 100°F under the same Heat Advisory before showers become more likely Monday night (22% chance) as monsoon moisture edges in. Boulder forecasters expect that moisture to stick around into late next week, with Tuesday and Wednesday storms capable of locally heavy rain — a welcome, if bumpy, break from the heat.
