Honestly, if you're checking the santa fe nm weather forecast because you think you’re visiting a typical "desert," you’re in for a surprise. Santa Fe sits at 7,000 feet. That is high. Really high. It means the air is thin, the sun is a literal laser beam, and the temperature can drop 30 degrees the second the sun ducks behind the Sangre de Cristo Mountains.
Right now, as of Saturday, January 17, 2026, it is 26°F outside. It’s sunny, which is classic Santa Fe, but that "feels like" temperature is sitting at 18°F because of a northwest wind. If you walked out in a t-shirt because the sky looks blue, you’d regret it in about four seconds.
The Immediate Outlook: Sun, Wind, and Dry Air
The rest of today is looking clear. We’re hitting a high of 39°F, which isn't exactly tropical, but under that high-altitude sun, it feels warmer than the thermometer says. The humidity is super low—29%—so keep a water bottle glued to your hand. Dehydration up here hits different; it usually starts as a dull headache that people mistake for a hangover.
Tomorrow, Sunday, January 18, things mellow out a bit. The high jumps to 48°F with more sun. However, the wind is coming from the northwest at 8 mph, and we might see a few clouds roll in by nightfall. There’s a tiny 10% chance of some snow flurries overnight, but don't hold your breath for a powder day just yet.

The santa fe nm weather forecast is dictated by topography. Because we are at the tail end of the Rockies, we get actual seasons. In the winter, like right now in January, the nights are brutal. Tonight will bottom out at 16°F. That is "pipes-bursting" cold if you aren't careful.
- The UV Factor: Even when it’s 26°F, the UV index is a thing. Today it's low (around 1), but by noon it hits 3. At this elevation, you burn faster than you do at sea level. Wear the sunscreen.
- The "Dry" Cold: 20 degrees in Santa Fe feels better than 40 degrees in a humid place like Seattle. It doesn't "soak" into your bones. It’s a crisp, sharp cold.
- Wind Patterns: Usually, the wind comes from the northwest or west. When it kicks up—like the 14 mph gusts we're seeing today—it carries a bite.
What to Expect This Week
Looking at the mid-week santa fe nm weather forecast, we’re staying in a pretty consistent groove. Monday and Tuesday stay in the mid-40s for highs and mid-20s for lows.

Wednesday, January 21, is looking particularly dry with humidity dropping to 23%. If you have sensitive skin or eyes, this is the day you'll feel it. By Friday, January 23, we finally crack the 50°F mark. It’s a slow climb, but that’s January in the high desert for you.
How to Dress for This Forecast
If you’re heading to the Plaza or hiking near Museum Hill, the "onion method" is your only hope.
You need a base layer that wicks sweat, a middle layer for warmth (fleece is king here), and a wind-blocking outer shell. You’ll be stripping layers off at 2:00 PM and piling them back on by 4:30 PM. It’s just the rhythm of the city.

Most travelers under-pack for the nights. When the sun goes down, the heat vanishes into the thin atmosphere almost instantly. That 16°F low for tonight is no joke. If you're out for dinner, make sure your coat is actually rated for freezing temps, not just a light fashion jacket.
Actionable Tips for the Current Weather
- Hydrate now: Don't wait until you're thirsty. Drink twice as much water as you do at home.
- Lip balm is mandatory: The 23% to 29% humidity will chap your lips in hours.
- Sunscreen regardless of temp: The snow (if any is left on the ground) reflects the sun upwards. You can get a "snow burn" under your chin.
- Watch the wind: If you’re planning a hike, a 14 mph wind at 7,000 feet feels significantly more exhausting than at sea level.
Keep an eye on the sky toward the end of next weekend. By Sunday, January 25, the chance of snow jumps to 30% overnight. That’s the first real signal of a potential shift in the pattern. For now, enjoy the "City Different" in its cold, bright, and incredibly blue January glory.
