November in the Mojave: The Valley's Best Month, With Fine Print
Henderson's November means 70-degree afternoons, 40-degree mornings, and the hiking season's main event. It also means desert rules still apply.
November is the month the Las Vegas Valley's weather apologizes for the summer. In Henderson, average highs settle into the upper 60s and low 70s, overnight lows drop into the 40s, and the Mojave Desert delivers the clear, dry, golden days that fill trailheads and patios across the valley.
The daily swing is the signature: a 25- to 30-degree spread between afternoon and dawn is normal in desert autumn, which is why valley residents dress in layers and why the morning dog walk and the afternoon errand can feel like different seasons.
November is prime season for Henderson's outdoor assets — the River Mountains Loop Trail, the trails at Sloan Canyon National Conservation Area on the city's southern edge with its petroglyph panels, and the Henderson Bird Viewing Preserve, where fall migration brings waterfowl to the ponds of a facility built, improbably and successfully, at the city's water reclamation ponds.
The fine print matters. Desert cold is real cold: hikers heading into Sloan Canyon or up Frenchman Mountain should carry water even in cool weather — dehydration does not check the calendar — and afternoon winds ahead of Pacific fronts can turn sharp quickly. The season's first freezes usually reach the valley floor later in November or December, a cue to protect exposed pipes and tender plants.
The National Weather Service office in Las Vegas forecasts for Clark County, and its fall messaging emphasizes the other November hazard: darkness. With sunset before 5 p.m. by late month, trail users and cyclists plan around light, not temperature.
By desert standards, November is gentle. By any standard, it's the valley at its best — Henderson's reward for surviving August, paid out one clear day at a time.
