Guadalupe Mountains in December: what the park service says

December at Guadalupe Mountains is mostly sunny and mild down low, but the park service warns that November through March is the windy season, with winds often over 30 mph and gusts of 50 to 80 mph, and that snow and freezing fog are common in December and January at higher elevations. The color crowds at McKittrick Canyon are gone by now, so parking is easier. Pack for anything from below freezing to warm, a wind shell and traction for icy high trails, and remember pets are not allowed on park trails.
