Havasupai Falls

Weather is as clean as it gets for late April in the canyon. Highs in the 83–84°F range all three days with mostly sunny skies and light SE/S winds under 10 mph through Monday, picking up slightly to 20 mph gusts by Tuesday. Precip chances are negligible — 8–11% each day, nothing that signals actual storm activity. Nights are cool but comfortable, dropping to 48–51°F. The warming trend is gentle and consistent, so no spike in snowmelt-driven flash flood risk from upstream.

Havasu Creek is the main thing to watch on this trip and it's in good shape. The USGS gauges relevant to this drainage are all running at or below median with falling or stable trends — no upstream pulse coming. That said, the stream crossings on the trail into the campground can be ankle-to-knee deep even at normal flows, so expect wet feet on the approach and plan accordingly. Nothing dangerous here, just the usual wading.

The SNOTEL data in the briefing is from California stations that aren't meaningful for Havasupai — ignore it. The relevant upstream snowpack on the Coconino Plateau has been largely spent by mid-April in a typical year. With overnight temps staying well above freezing (lows in the upper 40s), any residual melt is slow and steady, not a sudden surge. No flash flood watch or warning is in effect per NWS.

No active fires within 50 miles means you'll have clean air and clear views into the canyon walls. With 13+ hours of daylight and sunset at 7:08 PM, you have plenty of light for the 10-mile hike in. Start the approach by 7–8 AM to get into camp before peak afternoon heat — that canyon floor will be radiating by 2 PM. Mooney and Beaver Falls are at their most beautiful this time of year with good water volume. Enjoy it.
