Colorado Goes Red: Every Single County Under Air Quality Alert
Colorado Blanketed in Wildfire Smoke: What You Need to Know
What’s Happening Right Now
Colorado is currently experiencing a statewide air quality alert due to wildfire smoke drifting in from multiple states. Here’s what you need to know in simple terms:
Important: A statewide air quality health advisory is in effect for ALL Colorado counties until at least 9 a.m. Wednesday.
Where Is the Smoke Coming From?
The smoke isn’t coming from just one place—it’s like Colorado is caught in a smoke sandwich:
- From the West: Wildfires burning in Utah and Nevada
- From the North/Northeast: Fires in other "upwind" states (states where wind blows toward Colorado)
- From the Pacific Northwest: Additional smoke pushed in by a recent cold front
Why so widespread? The smoke is entering Colorado from multiple directions at once, which is why the advisory covers the entire state.
The Cold Front Connection
Here’s where weather makes things interesting:
What Happened
- Monday: Denver hit a record-breaking 102°F (that’s HOT!)
- Monday Night: A cold front rolled through, dropping temperatures to 57°F overnight
- The Twist: This cold front brought cold, dense air that acts like a blanket, trapping smoke closer to the ground where we breathe
Weather Expert Insight: Meteorologist Abby Pettett explains that while smoke was already coming from the west, the cold front added more smoke from Pacific Northwest fires and pushed it down to ground level.
What’s Next? (Timeline)
Here’s what meteorologists expect:
| Day | What to Expect |
|---|---|
| Tuesday | Smoke lingers throughout the day |
| Wednesday | Surface-level smoke (the stuff we breathe) starts to lift; advisory expires 9 a.m. |
| Thursday | Upper-level smoke (hazy skies, colorful sunsets) may start to decrease |
| Thursday+ | Temperatures climb back to the 90s |
| Weekend | Possible triple-digit heat (near 100°F+) |
Good News: Tuesday’s high of 73°F will be "the coolest day we see for a while," says Pettett.
Temperature Rollercoaster Ahead
Denver is in for a wild temperature ride:
| Day | Expected High | Notes |
|---|---|---|
| Tuesday | 73°F | Coolest day of the week |
| Wednesday | Warming up | |
| Thursday | 90s | Back to summer heat |
| Saturday (Aug 8) | Near 100°F | Could tie record high |
| Sunday (Aug 9) | 100°F+ | Could break record high |
Record Watch: Denver’s records for Aug 8 & 9 could be challenged or broken this weekend.
What Should You Do?
Important Health Tips During Smoke Events:
- Stay indoors as much as possible
- Keep windows/doors closed
- Run air purifiers if you have them
- Limit outdoor exercise (especially kids, seniors, and those with asthma/heart conditions)
- Check air quality before going outside: colorado.gov/airquality
- Use N95/KN95 masks if you must be outside for extended periods
Quick Summary

- Smoke from multiple states (Utah, Nevada, Pacific Northwest, others)
- Cold front trapped smoke at ground level after dropping temps 45°F overnight
- Smoke clears Wednesday (ground level), Thursday (upper level)
- Heat returns fast — 90s by Thursday, possible 100°F+ this weekend
- Stay indoors, filter air, limit outdoor activity until air improves
FAQ
1. Is the smoke from fires in Colorado?
No. The smoke is drifting in from fires burning in Utah, Nevada, the Pacific Northwest, and other upwind states. Colorado isn’t the source—it’s just downwind.
2. Why did the cold front make smoke worse?
Cold air is denser than warm air. When the cold front arrived, it acted like a lid, trapping smoke near the ground instead of letting it rise and disperse. Plus, the front’s winds brought more smoke from the Pacific Northwest.
3. When will I be able to open my windows again?
Likely Wednesday. Surface-level smoke (the unhealthy kind at breathing level) should start lifting Wednesday as winds shift. Upper-level haze may linger through Thursday but is less of a health concern.
4. Is it safe to exercise outdoors Tuesday?
Better to skip it. With the statewide advisory, air quality is unhealthy for sensitive groups and potentially unhealthy for everyone. Move workouts indoors or wait until Wednesday.
5. Will the weekend heat be dangerous?
Yes, potentially. Triple-digit heat combined with possible lingering smoke creates a double hazard. Stay hydrated, limit outdoor time during peak heat (10 a.m.–4 p.m.), and check on vulnerable neighbors.
