Havasupai Falls

The weather is as good as November gets for Havasupai. Highs of 70-71°F and lows of 39-41°F across all three days, with light winds under 6 mph and clear skies throughout. No precipitation in the forecast. You'll be comfortable hiking in and out in a t-shirt during the day and need a solid insulating layer at night — 39°F in a canyon is colder than it sounds with any breeze.

The stream flow data attached to this briefing is from USGS gauges in coastal California — San Antonio River, Salinas River, Llagas Creek near Gilroy — none of which have any hydrological connection to Havasu Creek or the Colorado River drainage. This data tells you nothing about crossing conditions on the trail to the falls. Havasu Creek can fluctuate significantly based on upstream conditions and tribal water management. Contact the Havasupai Tribe directly at (928) 448-2121 to get current creek levels before you drop in. Don't assume conditions are benign just because the weather is dry.

Daylight is limited — 10h 24m with sunset at 5:28 PM. The standard trailhead-to-campground hike is 10 miles. If you're hitting the trail at noon today as planned, you have roughly 5.5 hours of usable light. Move with intention on day one and have headlamps accessible, not buried in your pack. For the remaining days, an early start gives you full daylight for exploring the falls and side canyons.

No fires within 50 miles and no avalanche terrain relevant to this location. Air quality is clean. The canyon itself is sheltered and the forecast is about as benign as it gets — this is a great window to be down there.
