Summer is in full swing, and San Diego is starting to feel the heat—literally. As temperatures climb, several popular hiking trails have been temporarily closed due to extreme heat warnings throughout the month of August.
Trail Closures for August
Three major trails—El Capitan Preserve, Hellhole Canyon, and Mount Gower—have been closed to protect hikers from dangerously high temperatures. In addition to safety, the closures also allow park staff to complete much-needed trail maintenance. While these trails are expected to reopen next month, others like Agua Caliente and Vallecito have been closed since May and are scheduled to reopen after Labor Day.
Hike Smart, Even If the Trail’s Open
If you're planning to hit any open trails, officials stress the importance of proper planning. That includes:
- Starting hikes early in the morning
- Wearing light-colored, breathable clothing
- Bringing extra water and electrolyte drinks
- Avoiding peak heat hours (usually midday)
Even seasoned hikers are urged to be cautious, and beginners should consider postponing any strenuous activities until the temperatures ease.
How Hot Will It Get?
Forecasters say the most intense heat will hit Wednesday through Friday, especially inland:
- Ramona and Escondido: Mid-90s
- Campo (near the U.S.-Mexico border): 99–100°F
- Borrego Springs: 113–115°F
The heat wave is being fueled by a high-pressure system out of New Mexico. Luckily, the coast should remain a bit cooler, staying about 1–2 degrees below normal thanks to marine influence.
Wildfire Risk Elevated
San Diego Gas & Electric is warning of increased wildfire risk in areas east of I-15. Their fire risk monitor indicates elevated conditions countywide, so residents and visitors alike should remain alert.
Bottom Line: Whether you're a casual weekend hiker or a trail veteran, now’s the time to put safety first. Pay attention to closures, respect the heat, and plan accordingly—San Diego’s trails will still be there when the temps cool down.
