January is a beautiful month in the mild winter of Las Vegas when the average high temperature is about 58°F (14.4°C). Winter is chilly with average lows at about 39°F (3.9°C).
Sunshine is ample in the day while the evenings see a quick drop in the mercury column after sunset. Las Vegas' high altitude keeps it cooler than other places in the desert. New Year mostly experiences low freezing temperatures during the night. Keep an eye on the snow-sprinkled Sierra Nevada mountain range - it is an amazing sight in the winter.
Wear a warm winter coat before hopping on the Strip for a night of clubbing in Sin City.
