You’ve probably heard that New Mexico is basically a giant, scorched desert where the sun never stops beating down. Honestly? That’s the first mistake people make when looking at the 10 day weather for Santa Fe NM.
If you’re packing flip-flops and a tank top for a January trip to the "City Different," you’re in for a very cold, very rude awakening. Santa Fe sits at over 7,000 feet. That altitude changes everything.
Right now, as of Saturday, January 17, 2026, it is 35°F outside. But here is the kicker: with a 13 mph wind coming out of the north, it actually feels like 26°F. It’s sunny, sure, but it’s that sharp, high-altitude sun that looks warm through a window and bites the second you step out the door.
The Reality of the 10 Day Weather for Santa Fe NM
People see "New Mexico" on a map and think Phoenix. Big mistake. Santa Fe is more like a ski village than a desert oasis in the winter.
Today, we’re looking at a high of 39°F and a low that’s going to crater at 16°F tonight. That’s a 23-degree swing. If you aren't dressing in layers, you're doing it wrong.
What to Expect This Week
Tomorrow, Sunday, January 18, actually looks pretty decent. We’ll hit 48°F, which feels like a heatwave compared to today. It’ll be sunny all day, but keep an eye on the evening—the sky starts turning "mostly cloudy" and there’s a 10% chance of snow overnight.
Monday stays chilly with a high of 44°F and a low of 24°F. You might see a stray snowflake or two (5% chance), but it’s mostly just "partly sunny" vibes.
Tuesday and Wednesday (January 20-21) are carbon copies of each other. Highs of 46°F and lows of 26°F. Pure, unadulterated sunshine. This is that classic Santa Fe winter weather where the sky is so blue it almost hurts to look at it, but the air is crisp enough to keep you moving.
The Turn Toward the Weekend
By Thursday, January 22, things start to shift. We're looking at:
- High: 47°F
- Low: 27°F
- Condition: Partly sunny with a tiny 5% chance of snow.
Friday and Saturday (January 23-24) actually crack the 50°F mark. It’s the warmest part of the forecast. If you’re planning on hitting the Plaza or walking Canyon Road, these are your days. Just remember that even at 50 degrees, the 6-7 mph winds will make the shade feel significantly colder than the sun.
Why the Altitude Sabotages Your Forecast
There is a weird science to why the 10 day weather for Santa Fe NM feels different than the numbers on your phone. At 7,198 feet, the atmosphere is thin.
There's less air to hold onto the heat. The second the sun drops behind the Jemez Mountains, the temperature doesn't just "cool down"—it falls off a cliff.
You also have to deal with the UV index. Even today, with a high of 39, the UV index is a 3. In the summer, it’s off the charts. But even in January, that high-altitude sun will burn you if you're out hiking for a few hours. Wear sunscreen. Seriously.
Humidity (Or Lack Thereof)
The humidity today is sitting at a bone-dry 19%.
For people coming from the East Coast or the South, this is a shock to the system. Your skin will crack. Your nose might bleed. You’ll be thirstier than you’ve ever been. The low humidity is why it doesn't feel "muggy" even when it’s warm, but it also means the cold feels "sharper."
Looking Toward Next Monday
The end of the 10-day stretch brings a bit of drama. Sunday, January 25, sees a 30% chance of snow at night with a low of 28°F.
By Monday, January 26, the forecast calls for a 35% chance of snow showers. Highs will drop back down to 48°F. It’s not exactly a blizzard, but in Santa Fe, even a light dusting can turn the adobe buildings into a literal postcard.
Actionable Tips for Your Trip
- Hydrate like it’s your job. The dry air and altitude will dehydrate you before you even realize it. If you're drinking margaritas at The Shed, double your water intake.
- The 3-Layer Rule. Base layer (moisture-wicking), middle layer (fleece or wool), and a wind-blocking outer shell. You will be taking these off and putting them back on all day.
- Check the Wind. A 14 mph wind (like we have today) makes a 39-degree day feel like the mid-20s. Always look at the "Feels Like" temp.
- Sun Protection. Sunglasses aren't optional here. The glare off the snow (if there is any) or just the sheer intensity of the light is no joke.
The 10 day weather for Santa Fe NM shows a pretty classic New Mexico winter: freezing nights, sunny days, and the occasional threat of snow to keep things interesting. Plan for the 16-degree lows, and you’ll enjoy the 50-degree highs a whole lot more.

Next Steps for Your Santa Fe Visit:
Check the specific hourly wind speeds if you plan on visiting Ski Santa Fe, as ridge-top gusts can be significantly higher than the city forecast. Pack a high-SPF lip balm and a heavy-duty moisturizer to combat the 19% humidity levels expected this week.
