Denver is in for a scorcher this Monday, July 20, with sunny skies and a high near 100°F this afternoon under a Heat Advisory in effect until 9 PM for the Denver Metro and I-25 Corridor. Front-load your outdoor plans into the morning and save anything strenuous for after sunset.
Today’s Setup
An upper-level high is parked right over Colorado today, according to the National Weather Service Denver/Boulder office, which is why we’re topping out near 100°F with light north-northeast wind around 1 to 8 mph. Overnight lows only dropped to around 70 before climbing again, so there’s not much relief before sunrise.
Best Window To Be Outside
Morning, before roughly 10 a.m., is your best window — temps are still climbing out of the 70s and winds are calm. It’s a solid time to squeeze in nine holes before the heat builds; toss a golf glove men leather and golf towel microfiber in the bag. Things don’t really loosen up again until after sunset, when lows settle back near 70.
Heat Advisory & Evening Storm Chances
The plains stay dry through the afternoon, but forecasters note an outflow boundary drifting off the mountains could spark a slight chance of showers and storms along the northern I-25 Corridor by early evening, with a 17% chance overnight. Between now and 9 p.m., limit time outside, check on elderly neighbors and pets, and keep the AC running.
Tonight’s Big Events: Rockies, Forrest Frank & More
Colorado Rockies vs. Washington Nationals plays at Coors Field tonight — first pitch will still feel like the upper 90s, cooling into the 80s by the later innings, so hydrate before you tailgate. Grab a Colorado Rockies jersey or Colorado Rockies fitted cap, and find tickets on SeatGeek or tickets on StubHub. Prefer air conditioning? The Forrest Frank: The Jesus Generation Tour hits Ball Arena tonight — pick up a Forrest Frank t-shirt or Forrest Frank hoodie beforehand. Hilary Duff also plays an outdoor set at Red Rocks tonight, so bring water if you’re headed up the amphitheater stairs.
What To Wear Or Bring
Light, breathable clothing, sunscreen, and a hat are musts. If you’re cooling off at home, the 2-Person Intex Floating Lounge with Cooler is worth a look for the backyard pool, and check outdoor gear deals while you’re at it.
With temps this high, grilling beats standing over a hot stove — burgers, steaks, or grilled chicken with corn on the cob are the move tonight. An instant-read meat thermometer takes the guesswork out of doneness, and a grill brush and scraper set keeps things clean between cookouts. Need ingredients? You can order groceries on Amazon and have everything for tonight’s dinner delivered to your door.
Next Few Days
A cool front moves through late tonight into Tuesday morning, dropping highs to near 94 as monsoon moisture finally arrives. From Tuesday through Thursday, expect scattered, slow-moving storms capable of locally heavy rain — Tuesday night’s precipitation chance jumps to 48%. It’s only a slight cooling trend overall, so check the full Denver weather forecast before finalizing weekend plans.
