The Narrows — Zion

The stream crossing data in this briefing is pulled from California gauges (Salinas River, Alameda Creek, Llagas Creek near Gilroy) — none of which are the Virgin River. Discard those numbers entirely for trip planning purposes. For The Narrows, the only flow data that matters is USGS gauge 09405500 (Virgin River at Springdale). Check it before you leave and again the morning you drop in. NPS flash flood closure thresholds typically kick in around 150 cfs; anything above 50-60 cfs makes the narrows section significantly more committing. With no precipitation in the forecast and stable snowpack at zero inches across all SNOTEL stations, flow is unlikely to spike during your trip — but verify rather than assume.

Weather is genuinely good. Highs of 50-54°F with light winds (3-7 mph) and sunny skies all three days. Overnight lows will drop to 31-34°F, so you're looking at freezing temps in the canyon each night — wet gear and wet feet from wading will amplify that cold significantly. A dry set of camp clothes sealed in a dry bag is worth the weight here. The canyon walls don't see much direct sun in November, so don't expect daytime warmth to bail you out if you're soaked.

No active fires within 50 miles, no smoke concerns, no avalanche terrain in play. Those are non-issues. The one logistical constraint worth planning around is daylight: sunset at 5:33 PM with only 10.5 hours of usable light. If you're doing top-down from Chamberlain's Ranch, that's a long day — start no later than 7:30 AM to have comfortable daylight margin. Bottom-up day sections can be more flexible, but if you're camping in the narrows, get camp established well before 4:30 PM so you're not setting up in the dark with wet hands.

Overall this is a solid weather window for a November Narrows trip. Cold, clear, and calm. Nail the flow check, manage your thermal layers for wet wading in near-freezing nights, and account for the short daylight window on your pacing plan.
