December in Bend is winter in full: highs around 40, cold nights in the low 20s, regular snow, freezing fog, and the heart of the holiday season with Mt. Bachelor open and the ski season underway. The days are short and the sun low, the basin sees frequent freezing fog and ice on cold mornings, and the snow comes and goes between storms and clear cold spells. It is the start of the deep-winter stretch, festive in town and snowy in the mountains.
What Is the Weather Like in Bend in December?
December in Bend is cold and snowy, with daytime highs around 40, overnight lows in the low 20s, and regular snow as winter settles in. The days are the shortest of the year around the solstice, the sun stays low, and the cold lingers, but the high desert still delivers bright, clear cold spells between storms. Snow comes and goes in town, while the mountains build the deep snowpack that defines the ski season.
The defining hazards are the same as midwinter: snow, ice, and especially freezing fog, which pools in the Deschutes Basin on calm, clear cold mornings and glazes roads without any snowfall. Cold air drains into the basin under strong inversions, trapping fog and any wood smoke. The pattern alternates between snowy, gray, foggy stretches and brilliant cold bluebird days, the underlying climate covered in the Central Oregon climate guide.
Snow and the Start of Ski Season
December is when Bend's ski season hits full stride, as Mt. Bachelor builds its base and the snow becomes deep and reliable up high. The mountain is typically open and spinning lifts, the holiday season brings a surge of skiers and snow-players, and the early-winter storms refresh the slopes regularly. Town snow comes and goes, but the high country is firmly in winter.
For skiers, December is the festive start of the season, with deepening snow and holiday energy, balanced by short days, cold temperatures, and real winter driving to reach the mountain. The summit can be far colder and windier than the base, so dress for the conditions up high, covered in the Mt. Bachelor weather guide. December launches the winter sports season in earnest.
Freezing Fog and Short, Cold Days
December mornings in Bend frequently bring freezing fog and ice, the season's biggest daily hazard, as cold air pools in the Deschutes Basin under strong inversions and the short days give little time to thaw. The fog can form overnight and linger for hours or all day in a deep inversion, glazing roads, sidewalks, and windshields with rime and clear ice. This is ice without snow, which catches out drivers who only watch for snowfall.
The short days compound the problem: with the sun low and daylight brief around the solstice, ice clears slowly and shaded roads stay slick all day. The same inversions trap cold air and wood smoke, covered in freezing fog and Central Oregon inversions. Build extra time into cold, foggy December mornings and treat bridges and shaded roads as slick.
December Recreation
December's recreation centers on snow, with Mt. Bachelor open, Nordic skiing and snowshoeing in the high country, and the holiday season in town. The deepening snowpack opens up the full range of winter sports, from downhill and Nordic skiing to snowshoeing and sledding, and the festive in-town atmosphere adds to the appeal. The short days mean planning around the limited daylight.
Lower-elevation activity is weather-dependent and shaped by the cold, snow, and morning ice, but the mountains are the draw this time of year. The cold, clear bluebird days between storms can be spectacular for getting out. For the rest of the year see the Bend by-month guide.
Is December a Good Time to Visit Bend?
December is a great time to visit Bend for snow, skiing, and the holiday season, as long as you come ready for cold, short days, and winter driving. Skiers and snow-players will find the mountain open and the season underway, and the festive town atmosphere makes for a cozy winter visit, but the freezing fog, ice, and brief daylight are real factors. It is genuine deep-winter weather.
Pack for deep cold and ice, plan snow activities up at the mountain, build mornings around the freezing fog, and make the most of the short daylight. For packing specifics see what to pack for Bend by month. December is Central Oregon's winter and holiday season at its start, snowy and festive for those who come prepared for the cold.
