If you’ve ever stood on the edge of the Eastern Plains just as a summer storm rolls in, you know that the weather in Bennett Colorado isn’t just a forecast. It’s an event. Bennett sits in that unique, somewhat volatile space where the high desert meets the wide-open prairie, roughly 35 miles east of Denver. Because it’s away from the "urban heat island" of the city but still influenced by the massive rain shadow of the Rockies, the conditions here can be, well, a bit dramatic.
Most people moving to the I-70 corridor expect "Denver weather." Honestly, that's a mistake. Bennett is higher, windier, and often significantly more intense.
Why the High Plains Atmosphere Hits Differently
Bennett’s elevation is about 5,485 feet. That's a mile high plus a little extra for good measure. This height means the air is thin and holds very little moisture. In the winter, you’ll experience "bone-dry" cold that makes 20 degrees feel surprisingly manageable as long as the sun is out. But once that sun dips behind the Front Range? The temperature drops like a stone.
It’s not uncommon to see a 40-degree swing in a single day. You might start your morning scraping frost off the windshield in a heavy parka and end it eating lunch in a T-shirt. This isn’t an exaggeration; it’s a Tuesday in October.
The Wind Factor
If there is one thing that defines the weather in Bennett Colorado, it’s the wind. Unlike the sheltered neighborhoods in central Denver, Bennett is wide open. There are no skyscrapers or dense forests to break the gusts.
- Winter Wind: Can turn a light dusting of snow into a full-blown ground blizzard, closing I-70 at Tower Road or Airpark because visibility hits zero.
- Spring Wind: Often brings "Red Flag" warnings. The humidity drops to single digits, and the wind howls at 40+ mph, turning the prairie into a tinderbox.
- Summer Wind: Usually precedes the massive afternoon thunderstorms that define July.
Breaking Down the Seasons: What to Actually Expect
Let's get into the nitty-gritty of the calendar. If you're planning a move or just visiting, the "averages" only tell half the story.
Summer: Hot, Dry, and Electric
July is officially the hottest month, with average highs hitting around 87°F to 90°F. However, it’s a "dry heat." You won't find the soul-crushing humidity of the Midwest here. The real story in summer is the afternoon convective storms. Around 2:00 PM or 3:00 PM, clouds start building over the mountains. By 4:30 PM, they’ve marched east to Bennett.
These aren't just rain showers. They are often severe. We're talking about heavy hail and, occasionally, tornadoes. In May 2025, a significant tornado event damaged nearly 20 structures in the Bennett area, a stark reminder that the Eastern Plains are essentially the start of Tornado Alley.
Winter: The Long, Sunny Chill
Winter in Bennett is a paradox. It’s very cold, with December lows averaging about 19°F, but it’s also incredibly sunny. Colorado famously boasts over 300 days of sunshine, and Bennett gets a front-row seat.
Snowfall averages are tricky. Some years you’ll get 20 inches total; other years, a single "upslope" storm will dump two feet of heavy, wet snow in 24 hours. The North American Mesoscale (NAM) models often struggle with Bennett because a slight shift in wind direction can mean the difference between a sunny day and a state of emergency.
Spring: The "Mud" Season
Spring is arguably the most unpredictable time. April is the cloudiest month of the year, and it’s when Bennett sees its most frequent precipitation. You might get a 70-degree day followed by a foot of "heart attack" snow (that heavy, slushy stuff that breaks tree limbs).
Survival Tips for Bennett's Climate
If you’re living here, you learn the "Bennett lean"—how to walk against a 30-mph gust without falling over. But for the uninitiated, here is the survival kit:

- Layering is a Religion: Never leave the house without a shell or a light jacket, even if it’s 80 degrees. The temperature will drop 15 degrees the second a cloud covers the sun.
- Moisturize or Perish: The humidity in January can hover around 15% to 20%. Your skin will crack, and you will get static shocks from every doorknob. Get a high-quality humidifier for your bedroom.
- Check the CDOT Alerts: Before you hop on I-70 to go to Denver, check the Colorado Department of Transportation (CDOT) app. The "Bennett to Airpark" stretch is notorious for icing over while the rest of the highway is perfectly dry.
- Hail Protection: If you have a car, you need a garage or a carport. Bennett gets pummeled by hail almost every June. Those "golf ball sized" reports you hear on the news? They’re usually happening right over the 80102 zip code.
The Reality of Precipitation
Bennett is semi-arid. Most of the moisture comes in short, violent bursts during the "wet season" from April to September. July is technically the wettest month, but it’s mostly from those 20-minute deluges that turn the dirt roads into "gumbo" mud.
If you are gardening, forget about anything that can't handle high wind and low water. Native buffalo grass and xeric plants are your best friends. Trying to maintain a lush, Kentucky bluegrass lawn in Bennett is a fool's errand that will cost you a fortune in water bills.
Understanding the Upslope
You’ll hear local meteorologists talk about the "upslope" constantly. Basically, when the wind blows from the northeast, it pushes air up against the mountains. This air cools, condenses, and dumps massive amounts of snow on places like Bennett and Aurora. This is why Bennett can sometimes get hammered while the actual mountains (on the west side of the divide) stay dry.

Final Thoughts for Newcomers
The weather in Bennett Colorado is beautiful in a rugged, uncompromising way. The sunsets are better than anything you'll see in the city because there's nothing to block the view. The stars are brighter because the air is clear. But you have to respect the elements.
Watch the horizon. If the clouds look green in July, get your car under cover. If the wind starts picking up in January, make sure your gas tank is full. Living in Bennett means being in tune with the sky.
To stay ahead of the curve, your next steps should be to install a reliable local weather app like Weatherbug—which often has better localized station data than the generic apps—and sign up for Adams County emergency alerts. If you're a homeowner, it's also worth scheduling a roof inspection every two years to check for the inevitable hail bruising that characterizes the Eastern Plains.
