How is Las Vegas Weather in December? It’s one of the city’s coldest months in any year. Winter season happens in this month to a full extent. Average temperatures in this month float around 47 degrees Fahrenheit, with highs of 58 and lows near 34. January is actually a few degrees warmer on average.
Temperatures do fall below freezing in Las Vegas in December, but usually only three times a month. It’s great weather if you want to dine in, do some casino gambling, or enjoy the theater shows. It’s not ideal for getting a tan. If you want to spend time in or by an outdoor pool, then go in September or August.
The chances of rain are higher in December than other months, as the odds go up starting in November. Having said that, it is an arid desert climate. At no point in December is there often more than an average 12 percent chance of rain on any given calendar day. Las Vegas precipitation is often light to moderate rain or even light snow, but it’s usually only over three or four days per month every December.
December gets about seven hours of sunlight each day in December. As it sits in the Northern Hemisphere, the nights are longest in December with the shortest days, particularly around the winter solstice, a few days before Christmas. Still, the median cloud coverage is typically 0 percent, so while it might not warm you up that much, you can expect a lot of sunlight and clear blue skies while visiting here.
Humidity is not much of an issue for a desert city. Relative humidity here in December fluctuates between a dry 23 percent and a mildly humid 65 percent. It rarely falls under the really dry marker point of 13 percent or above the very humid point of 91 percent. The air is usually driest around the start of the month when most days are rated dry. It’s more humid around the solstice or Christmas when more days are humid, but still only mildly so. Depending on where you visit from, it might always seem dry.
Wind is another consideration about Las Vegas weather in December. It’s usually calm or a gentle breeze, rarely proving to be more than a fresh breeze. The highest average speeds of wind tend to be at the start of the month, with the lowest speeds happening more around the 10th.
