Yuma Time Zone: Why Your Tee Time Might Be an Hour Off

The Yuma time zone is Mountain Standard Time all year: Arizona time, UTC-7, with no daylight saving. Yuma's clocks never change. Everything around it does, which is why visitors from California, Mexico and now Alberta can turn up an hour early or an hour late for a tee time. In winter 2026-27 Yuma is one hour ahead of San Diego.

Here is how Yuma's clock lines up with every place a golfer is likely to come from or visit, with the exact 2026-27 dates.

Quick facts

• Yuma: MST (UTC-7) all year, the America/Phoenix zone. No clock changes for 2020 to 2029.
• Same as Yuma all year: Phoenix, Wellton, San Luis Rio Colorado (Sonora) and, since 2026, Vancouver.
• One hour behind Yuma in winter, the same in summer: San Diego, Palm Springs, Las Vegas, Los Algodones, the Andrade crossing and the Imperial Sand Dunes.
• One hour ahead of Yuma all year: Calgary and Edmonton (Alberta stopped changing clocks on November 1, 2026) and Saskatchewan.
• 2026-27 dates: California and Nevada fall back November 1, 2026, spring forward March 14, 2027 and fall back again November 7, 2027.

Yuma time zone vs the places around it

Arizona keeps MST all year outside the Navajo Nation. California, Nevada and Baja California use daylight saving on the same dates, so the whole Pacific side moves together.

What the Yuma time zone means for tee times

Yuma golf courses run on Arizona time all year, so a 9:00 AM tee time is 9:00 AM in Yuma whatever the date. The trouble starts when your phone, your flight or your plans are on another clock.

Arriving from California in winter. Leave San Diego at 9:00 AM Pacific and drive 2 hr 50 min, and you reach Yuma just before 1:00 PM on a Yuma clock, not just before noon. If your first round is booked for 1:00 PM, you will be rushing. See San Diego to Yuma.

Arriving from Phoenix. No change at all. The Phoenix to Yuma drive stays on Arizona time the whole way.

Early starts. At Desert Hills, the first tee time is sunrise or 6:00 AM MST, whichever is later. In winter that is one hour ahead of California. The Desert Hills course guide has the full booking rules.

Booking windows. Some online tee sheets open at midnight. Desert Hills opens each date at 12:00 AM eight days ahead, and Coyote Wash in Wellton releases times online 14 days out at 12:00 AM (the town brochure says 7 days by phone or GolfNow). Wellton is on Arizona time too, so there is no change on that drive. More on booking in Yuma tee times in winter.

Phones near the river and border. Cocopah Bend and the west side of Yuma sit beside the Colorado River, across from California. A phone near the river or the border can pick up a California or Mexican tower and show Pacific time. Set the phone to Arizona time manually if it jumps.

Short winter days on a fixed clock

Yuma's clock stays put, but winter days are short. Winter sunset is around 5:30 PM, and December has the coolest mornings of the year, about 47F at the airfield on average. Tee sheets compress into late morning and midday as a result.

A twilight start at 3:00 PM leaves about two and a half hours of light in midwinter, enough for a brisk 18 on a quiet afternoon but not a slow one. On the live Las Barrancas tee sheet for Saturday, October 24, 2026, late-day prices dropped further, to $35 from 3:00 PM and $25 later; the Las Barrancas course guide has the tees and booking rules. Rates were seen in October 2026 and change.

In summer the heat makes first light the only sensible time to play, and the same rule applies at Desert Hills: sunrise or 6:00 AM MST, whichever is later.

Yuma vs Los Algodones time

Los Algodones, in the municipality of Mexicali, Baja California, uses Pacific time with the same daylight-saving dates as the US: PST (UTC-8) from November 1, 2026 to March 14, 2027, then PDT (UTC-7) to November 7, 2027. So it is one hour behind Yuma in winter and the same in summer.

The Andrade port's posted hours are 6:00 AM to 10:00 PM Pacific time, which in winter is 7:00 AM to 11:00 PM on a Yuma clock. In summer the clocks match. The Quechan tribe's parking lot beside the port is open 7:00 AM to 11:00 PM Arizona time. Everything else about the crossing is in the Los Algodones day trip guide.

San Luis Rio Colorado, across the border south of Yuma in Sonora, stays on MST all year like Yuma, so there is no change there.

Yuma time for Canadian snowbirds: the 2026 changes

Two provinces changed their clocks in 2026, and both affect calls home and home-office hours from Yuma this winter.

For Albertans the gap with Yuma is the big change. In earlier winters Calgary and Edmonton matched Yuma from November to March. From November 1, 2026 they stay one hour ahead all winter. If you call home at 5:00 PM in Yuma, it is 6:00 PM in Calgary.

British Columbia went the other way: it has stayed on UTC-7 since March 8, 2026, so Vancouver now shows the same time as Yuma all year.

For flights, departure and arrival times are always local. A WestJet flight from Calgary that lands at Phoenix at 3:00 PM lands at 3:00 PM Arizona time, the same clock as Yuma. For more on getting here, read flights to Yuma for golf, Canadian snowbirds in Yuma and the Calgary to Yuma drive, which also covers the reduced winter border-crossing hours at Carway on the way home.

Day trips that cross the clock

Several rest-day trips from Yuma take you onto Pacific time in winter:

• Imperial Sand Dunes. The dunes are in California, on Pacific time. See Imperial Sand Dunes from Yuma.
• San Diego and Palm Springs. One hour behind in winter. You gain an hour going west and lose it coming back.
• Las Vegas. Pacific time, one hour behind in winter.

Trips east to Wellton and Las Barrancas in the Foothills, north to Kofa or Mittry Lake, and south to San Luis Rio Colorado stay on Yuma's clock.

A quick winter conversion table

This table applies from November 1, 2026 to March 14, 2027. From March 14, 2027, California, Nevada and Algodones match Yuma, and Toronto moves to three hours ahead. Alberta, Saskatchewan and BC do not change.

The same kind of split happens at other golf towns near a state line; the Mesquite time zone guide covers the Nevada-Arizona-Utah version.

Plan it on the map

Open the Yuma golf map to see every course, all on Arizona time, with drive times from downtown. The $30 plan can build a golf trip day by day, or for a winter stay set up a weekly course rotation, with every course on the same clock.
