As you look around at the melting bits of ice and snow left from the most recent storm here in Los Alamos county, you might hear your neighbors, friends, and coworkers reminiscing about times past “when we used to get LOTS of snow”, or even mournfully recalling those unusually warm winter days just a few weeks ago in December when we were basking in the sun at nearly sixty degrees. Regardless of which weather pattern you prefer, even long time residents of Los Alamos are struggling to remember what a “normal” winter in Los Alamos is supposed to be like.
First, let’s look at what our weather patterns suggest about our climate in general. According to a LANL website about Los Alamos, “In general terms, Los Alamos has a temperate mountain climate with four distinct seasons”.
Hmm. Okay then. Four seasons. So, what IS the average snowfall? Again, LANL’s website suggests, “snow, like rain, in Los Alamos is highly variable, but tends to average 28 inches annually”.
Holy cow! 28 inches annually? So, why isn’t the ski hill open every year? Well, because, as the LANL website reminds us, snow amounts are highly variable in our climate. A lot of us remember that huge snow we had in the winter of 2018 and 2019. Between the day after Christmas to New Year’s Day we had 22 inches of snow. It had been quite a while since we’d had such a prolific snow year and most of us were unprepared.
But pause for a moment and consider this:
The record snowfall for one day here in Los Alamos is 22 inches. That snow event happened back on January 15, 1987. Can you imagine? That entire storm from 2018-2019 happening in One. Single. Day? Los Alamos actually made the New York Times on January 19, 1987. The Times stated, “The storm was so severe that at its peak, four to five inches of snow fell every hour in Los Alamos.”
In Katrina Bennett’s blog, she takes a fascinating look at snowfall events here in Los Alamos in both 7-day and 14-day segments. You can view the blog post here. Katrina is a big fan of water and weather and points out that these snowfall events tend to occur every four to six years. The amount of these snow events has been affected by climate change. While we used to see larger events in a seven day period, Bennett estimates its been about 18 years since a seven day record event and about 10 years since a record setting 14 day event. The sustained drought has affected our average temperature, which impacts the amount of snow we see in a year. So while we aren’t getting quite as much at once, we are still going to see snow here in Los Alamos.

Something else to consider is that of the top 20 biggest snowfalls recorded in a day, only 8 of those happen prior to January. Of those 8, one is the 12.5 inch October 21, 1996 snowfall and another is the 22 inches received on November 22, 1931. The other six are December snowfalls and one of them is attached to that massive snow event in 1987. In fact, three of the TOP FIVE daily snowfall highs come from 1987. If you wanted amazing skiing at Pajarito, 1987 was your year. And if you’re dreaming of White Christmases, Los Alamos tends to offer White New Year’s Days or Valentines instead.
At the end of the day, those heavy snow winters are still statistically likely to happen in the future. Until then, something else Los Alamos does really well is sunshine. We average close to 300 days of sun per year and if you can’t have snow to play in, you might as well have sun to bask in.
