If you’ve ever stood at the edge of a sandstone mesa in San Juan County, you know the air feels different here. It’s thin. It’s dry. Honestly, the weather in Farmington NM is the kind of high-desert drama that keeps locals on their toes and leaves visitors reaching for their ChapStick.
Most people think "desert" and imagine endless, oppressive heat. That's a mistake. Sitting at an elevation of roughly 5,300 to 5,500 feet, Farmington is actually a semi-arid mountain basin. You've got the San Juan, Animas, and La Plata rivers meeting right in town—a "meeting place of waters" that the Navajo call Totah. This water keeps things greener than you'd expect, but the sky above? That’s where the real story is.
What Most People Get Wrong About Farmington Summers
July in Farmington isn't like July in Phoenix. Sure, it gets hot, but it’s a "dry heat" that actually means something when the sun goes down.
While the average high in July hits about 91°F, the temperature often swings 30 degrees by midnight. You can be sweating at a Farmington Scorpions baseball game at 4:00 PM and reaching for a light jacket by the time you’re grabbing a post-game burger. It’s basically climate whiplash. The record high hit 106°F back in July 2021, which felt like standing inside a convection oven, but those days are outliers.
Then there’s the monsoon.
From mid-June through September, the wind shifts. Moisture creeps up from the Gulf of California and the Gulf of Mexico, hitting the heat of the Four Corners. Suddenly, the afternoon sky turns deep purple. You get these localized, violent downpours that drop half an inch of rain in twenty minutes and then vanish. It smells like sagebrush and wet dust. If you're hiking in the Bisti/De-Na-Zin Wilderness during this time, you have to be careful; those dry arroyos can turn into rivers in seconds.

The Reality of Winter and "High Desert" Cold
Winter is where the elevation really shows its teeth.
It’s short, usually lasting from late November to late February, but it gets genuinely cold. In January 2026, we’ve already seen lows dip into the single digits. Just last week, on January 10th, the temperature hit a bone-chilling 1°F. People don't expect that from New Mexico.
Snow? We get it, but it doesn't usually stick around to make a mess.
- Average annual snowfall: ~12.3 inches.
- Coldest month: January (Average low of 21°F).
- Record low: -16°F (recorded in December 1990).
Usually, you get a few inches of light, powdery snow in the morning, and by 2:00 PM, the 270+ days of annual sunshine have melted it off the roads. It’s the perfect setup for people who like looking at snow-capped mountains but hate shoveling their driveway for three months straight.

Spring Winds and Fall Perfection
If you ask a local when the best weather in Farmington NM happens, they’ll say October. Without hesitation.
Fall is the "Goldilocks" zone. The cottonwoods along the Animas River turn a brilliant, neon yellow. The air is crisp, usually in the 60s or 70s, and the wind finally stops.
Spring, however, is the season of "The Wind."
In March and April, the pressure systems shifting over the Rockies create a funnel effect. You’ll get 40 mph gusts that carry fine red sand from the desert floor. It’s not exactly a "sandstorm," but it’s enough to make outdoor patio furniture a risky investment. It's the price we pay for those 300 days of blue sky.

Current 2026 Conditions and Trends
Right now, as of mid-January 2026, Farmington is seeing a fairly typical winter pattern. Highs are hovering near 49°F with lows around 24°F. It’s sunny, dry, and perfect for a walk along the Berg Park trails if you’ve got a decent coat.
Data from the New Mexico State University (NMSU) Agricultural Science Center shows that while our precipitation averages around 8 inches a year, we’ve been seeing more "clumped" weather—long dry spells followed by heavy, intense moisture events. This is consistent with regional climate shifts mentioned by experts at the National Oceanic and Atmospheric Administration (NOAA), where higher temperatures are slightly shortening the snowpack season in the nearby San Juan Mountains.
Actionable Tips for Navigating Farmington Weather
If you're moving here or just passing through, don't let the forecast fool you.
- The 20-Degree Rule: Always carry a layer. Even in June, if you're out past sunset, the desert floor loses heat rapidly. A hoodie is basically a legal requirement here.
- Hydrate or Else: The humidity in Farmington often sits between 10% and 30%. You are losing water just by breathing. If you wait until you’re thirsty, you’re already behind.
- Sunscreen is Non-Negotiable: At 5,500 feet, there is less atmosphere to filter UV rays. You will burn in 15 minutes in July if you aren't careful.
- Check the Arroyos: During monsoon season (July-August), never park or camp in a dry wash. Flash floods are real and they move faster than you can run.
- Wind Prep: If you’re visiting in the spring, bring wrap-around sunglasses. Your eyes will thank you when the afternoon gusts start kicking up the San Juan Basin dust.
To get the most out of your time in the Four Corners, plan your heavy outdoor activities like mountain biking at Glade Run for the early morning during summer, or the mid-afternoon during winter. The sun is your best friend or your worst enemy here, depending on the month. Keep an eye on the local NWS Albuquerque station for the most accurate "micro-climate" updates, as weather can change drastically between downtown Farmington and the higher elevations toward Aztec or Bloomfied.
