It might look clear out there right now, but don't let the weather fool you; there's a fair bit of crap to contend with if you're hitting the pavement or dirt today.
- Wildfire Smoke Advisory: While the immediate AQI looks good, an active fire in the Antelope Valley has triggered a smoke advisory for parts of Los Angeles County. Don't be surprised if you catch a whiff of burning chaparral, and if you're out towards the Eastern San Gabriel Mountains or the Antelope Valley, assume the air quality is worse than reported directly downtown.
- Major Downtown Road Closure: Forget your usual long run route through central LA. Wilshire Boulevard is shut down between MacArthur Park and Lafayette Park today until 9 PM for the "PARK TO PARK 2026" event. Plan your city runs accordingly, or prepare for some serious detours and crowds if you're near that area.
- Ongoing Trail Closures: Beyond current events, several key trails remain closed from past fire damage. Runyon Canyon is still a no-go, thanks to the 2025 Sunset fire. Closer to the Angeles National Forest, trails like Altadena Crest Trail and much of Eaton Canyon are out of commission until at least December 2027 from the 2025 Eaton Fire. Don't waste your time driving out there.
Today's Vitals (July 11, 2026)
Here’s the breakdown:
| Metric | Value | Notes |
|---|---|---|
| Temperature | 16.5°C (61.7°F) | Pretty much perfect for a run right now. Enjoy it. |
| Air Quality | AQI 18 (Good) | Looks stellar, but with the Summit Fire raging up in the Antelope Valley, keep an eye—and a nose—out. This "good" rating might not apply everywhere, especially if you're downwind or in affected areas like the Eastern San Gabriel Mountains. |
| Dominant Pollutant | Ozone/Other | Likely influenced by the wildfire activity. |
| Pollen Level | Moderate | Nothing to write home about for most, but if you're usually sensitive, grab your meds before heading out. |
| Condition | Mainly Clear | Today's weather is cooperating, but don't get complacent. |
Smoke Advisory in Effect!
The Summit Fire, currently burning over 2,500 acres in the Antelope Valley (Llano area), has prompted a smoke advisory for parts of Los Angeles County. While the main city AQI is low, those near the fire or in downwind areas like the Eastern San Gabriel Mountains and Antelope Valley Foothills should limit outdoor exposure, especially if you have respiratory issues. If you smell smoke, turn around. It's not worth the lung damage for an extra mile.
Persistent Trail Closures are a Pain
Don't bother driving out to Runyon Canyon expecting a quick hike—it's still closed thanks to fire damage from way back in January 2025. Similarly, a huge chunk of the Angeles National Forest, including trails around Eaton Canyon like the Altadena Crest Trail, remains off-limits until the end of 2027 for habitat recovery after the 2025 Eaton Fire. Check official sites before you hit the road; it'll save you a lot of frustration.
Brace for Next Week's Heat
Today's cool temps are a short reprieve. Forecasters are warning of an Extreme Heat Watch kicking in Tuesday morning through Thursday evening. Temperatures could hit 92-105°F in the valleys and inland areas, with some communities possibly seeing up to 112 degrees. Start hydrating now and plan your runs for dawn or dusk next week. Seriously, the middle of the day will be brutal.
