December is coldest month of the year in Las Vegas, NV. It’s a month when the daily low temperatures are often in the high 30’s, and where the daily highs average in the mid-50’s.

It’s also the slowest time of the year, visitor-wise. Which is why many of the popular shows along the Strip reboot and give their performance a break by going dark, (not having performances), during the month.

However the combination of mild weather and fewer visitors means deals can be had for hotels, along with fewer lines for buffets and shows. If you are leery of crowds, December may be the best time to go to Las Vegas.

I personally, have found incredibly cheap hotel deals in Las Vegas during December, even factoring in the resort fee. Plus, if you are from a cold part of the country, as I am, where the mercury can dip below zero, a daily high temperature in Las Vegas in the mid to high 50’s doesn’t sound so bad.

The normal daily low for Vegas in December is 38.7 degrees, (3.72 degrees Celsius). From December 14th to the 31st, the typical daily low is exactly 38 degrees. Everyone has their own temperature comfort level, but I’ve found that walking along the Strip late on a December night calls for a light sweater is all.

However I wasn’t walking on the Strip at night on December 23rd, 1990. That’s when Sin City hit the record for the coldest December day in the city’s history. On that day, Las Vegas residents felt a temperature of just 11 degrees. It was the one day that the hookers really needed those fur coats.

However the snowiest December in Sin City’s history was December of 2008, when the area was the recipient of 3.6 inches of snow. (Inches of precipitation are not the same as inches of snowfall.). This 3.6 inches of snow during the month all fell on one day, December 17, 2008.

Las Vegas Weather and Temperatures During Christmas

Coming out to Las Vegas during Christmas? The casino/hotels go all out with elaborate and beautiful decorations, even if the normal daytime weather won’t remind you of an old fashioned Christmas. Since they started keeping records, temperatures on Christmas Day have reached at least 60 degrees just over 1/3rd of the time.

The average high and low temperatures on December 25th in Las Vegas are 56 degrees and 38 degrees Fahrenheit respectively.

As far as a White Christmas in Las Vegas? It has never happened. There have been traces here and there on occasion, however the National Weather Service says that since they have been keeping records (1937), there has never been a recordable amount of snow on the ground in Las Vegas on a Christmas morning.
