January is Good for Las Vegas.
January is Vegas's coldest month — daytime 14°C / 57°F, nighttime 3°C / 37°F. Dry and sunny most days but the desert evening lows are real. CES (Consumer Electronics Show, early January, 170,000 attendees) drives hotel prices 3-5x for that week — book around the dates.
Off-CES weeks, January holds yearly-low hotel rates. Weekday rates can drop to $50-80 for 4-star Strip hotels (a $300 Saturday Bellagio room becomes a $90 Tuesday room). The trade-off is cold weather and short days (9h 55m daylight).

Las Vegas in January — Full Picture
January is Vegas's coldest month — daytime 14°C / 57°F, nighttime 3°C / 37°F. Dry and sunny most days but the desert evening lows are real. CES (Consumer Electronics Show, early January, 170,000 attendees) drives hotel prices 3-5x for that week — book around the dates.
Off-CES weeks, January holds yearly-low hotel rates. Weekday rates can drop to $50-80 for 4-star Strip hotels (a $300 Saturday Bellagio room becomes a $90 Tuesday room). The trade-off is cold weather and short days (9h 55m daylight).
Grand Canyon West occasionally gets snow — check the tour operator before booking. Red Rock Canyon stays accessible and is at peak hiking temperature. Pool season is effectively closed at most properties (Encore Beach Club + Wet Republic shut). Hot tubs and indoor spas are the pool replacement.
The smart-money January play is to target Tuesday-Thursday arrivals around mid-month (post-CES, pre-Valentine's), eat at the buffets that are running brunch-only winter hours, and focus on indoor activity (Cirque + Sphere + Mob Museum + Forum Shops walking).
What to Wear & What to Pack
Winter jacket + sweater + jeans + closed shoes. Evening lows drop to 3°C / 37°F — the desert loses heat fast after sunset. Pack a warm coat for night Strip walks. Days are mild and sunny but Vegas January nights are properly cold.
