About
January is one of the two coolest months of the year in Las Vegas. Over the 1991-2020 normals period, the average daily high at Harry Reid International Airport, the official climate station, is 58.5°F and the average low is 40.5°F. Days are mild, but evenings are cold enough for a real jacket.
Frost is possible but not common at the airport. The National Weather Service counts an average of 3.3 January nights at or below 32°F, and the coldest January reading on record is 8°F, set in 1963. The other extreme is milder than you might think: the warmest January day on record reached 77°F in 1975. The NWS notes that the airport sits in the urban heat island at the center of the valley, where overnight lows often run 5 to 15 degrees warmer than outlying areas, so if you are staying in Summerlin, Henderson or out near Red Rock, expect colder mornings than the official figures suggest.
Rain is light. A normal January brings 0.56 inches of precipitation, and the NWS describes Las Vegas as the driest major metropolitan area in the continental United States. Snow has fallen in about two-thirds of winter seasons, but it usually melts as it falls; measurable snow at the airport happens about once every four or five years, more often on the higher west side of the valley.
What to expect
CES, the big annual consumer technology show, opens the year. The organisers list CES 2027 for January 6-9 in Las Vegas, with registration and the official hotel booking channel (onPeak) already open. It is an industry event, so check ces.tech for who can attend before you plan around it.
The NHL season is in full swing, with the Vegas Golden Knights playing home games at T-Mobile Arena through the winter (their 2026-27 regular season runs to April 10, 2027 on the NHL schedule). Las Vegas Motor Speedway's Glittering Lights drive-through holiday display also stays open into the new year, running until January 4, 2027.

Good to know
- Pack layers. With normal lows around 40°F and occasional freezing nights, a warm jacket matters more than a swimsuit in January.
- Expect colder mornings away from the Strip. The NWS says the airport often runs 5 to 15 degrees warmer overnight than outlying parts of the valley on clear, calm nights.
- Rain and snow are uncommon. January's normal precipitation is 0.56 inches, and measurable snow at the airport is a once-every-four-or-five-years event.

Measurable snow at the official airport station typically happens about once every four or five years, while the higher west side of the valley, such as Summerlin, sees measurable snow roughly every three years.
When is CES 2027?
The organisers list CES 2027 for January 6-9 in Las Vegas. Registration is open on ces.tech, and the show's official housing agent, onPeak, is handling hotel bookings. CES is an industry event, so confirm on the official site whether you qualify to attend before planning a trip around it.
Is January a rainy month in Las Vegas?
Not by most standards. The normal January precipitation at Harry Reid International Airport is 0.56 inches for the whole month. The National Weather Service calls Las Vegas the driest major metropolitan area in the continental United States, because the Spring Mountains and the Sierra Nevada block much of the moisture coming in from the Pacific.
What should I pack for Las Vegas in January?
Bring clothes for cool days and cold nights. Normal highs are near 59°F and lows near 41°F, with a few freezing nights in a typical January. A warm jacket, long trousers and closed shoes cover most days. A light layer is useful indoors and out, as the gap between afternoon and late-evening temperatures can be wide.
