January Temperatures in Vegas

Like most other places in the Northern Hemisphere, January is the coldest. The average daily high temperatures in Las Vegas are about 59 °F (15 °C), and the average low temperatures are 39 °F (3.9°C)(source).

It can be quite cold in the morning (occasionally slightly below freezing) and warm up so much during the day you will need to start shedding clothes or turn on the air conditioner if you’re driving. The sun here is intense, even during the winter, and if you’re outside in the sun and it isn’t windy, you may begin to get hot.

This significant difference means you’ll likely have to pack both a winter jacket and a lighter summer one. Once the sun dips below the horizon in the evening, you will instantly feel it get significantly colder again.

On average, it rains only 1-3 days in January in Las Vegas, and usually, that doesn’t mean more than a few drops. Due to its location in the desert, Las Vegas has a very mild winter climate when compared to most other states. 

In regard to crowds, January is pretty chill (pun intended) in Las Vegas because Christmas and New Year tourists have gone. Hotel prices are very favorable during the month, and there’s little seasonal activity. Do not expect pool parties in January in Las Vegas, for most pools close in winter. 

However, the strip offers numerous entertainment options, including plenty of shows and concerts. Other attractions are also less packed during this month.

Note: You can usually tell the locals from the visitors during the winter months in Las Vegas. The locals are bundled up in winter jackets, while visitors (especially those from the coldest parts of the U.S.) are wearing shorts and t-shirts.

February Temperatures in Vegas

February is a bit warmer than January, with average daily high temperatures of 64 °F (17.71 °C) and average low temperatures of 44 °F (6.6 °C). Temperatures gradually increase throughout the month.

Things to keep in mind if you’re going to Vegas in February: 

  • Rains are rare in February.
  • Snowflakes are unlikely.
  • February is not too busy apart from Valentine’s day weekend and during the super bowl. 

Moderate crowds are escaping harsh weather from Northeastern states. Bring a sweater and a light jacket to wear during the colder mornings and evenings. You can pack a medium jacket and layer if you intend to stay out late into the night. As always, there’s an adequate number of fun activities in Vegas during February, so you definitely won’t be bored.
