DEMING — This Christmas holiday period is shaping up to be much warmer than what residents of southwest New Mexico typically experience in late December, according to long-term climate data from the National Weather Service and NOAA.
In a normal December, Deming averages daytime highs in the mid-50s, with overnight lows commonly dropping into the upper 20s to low 30s. Those figures are based on long-term climatological normals compiled from decades of observations at nearby official weather stations.
This year, however, temperatures during Christmas week are climbing well above those averages, with afternoon highs forecast to reach the low to mid-70s. That places current conditions roughly 15 to 20 degrees above what is considered normal for late December in Deming.
National Weather Service forecasters note that while occasional warm days can occur during winter in southern New Mexico, sustained warmth of this magnitude around Christmas is uncommon. Meteorologists attribute the mild conditions to a persistent warm air pattern across the Southwest, allowing daytime temperatures to surge despite the winter calendar.
While a single warm holiday period does not define a long-term trend by itself, the contrast between historical December averages and this year’s Christmas forecast is significant. For many residents, it means a holiday season that feels more like early fall than the heart of winter.
Forecasters continue to monitor conditions heading into the final days of December, but for now, Deming residents can expect a warm and pleasant Christmas, well above the temperatures normally associated with the season.
