You’re sitting at the airport, drink in hand, ready for Baja. You check your phone. Then you check the wall clock. Something feels off. Most people heading to the tip of the Baja California peninsula assume they know the time, but the truth is, Mexico changed the rules recently. If you are wondering what time zone Cabo San Lucas uses, the short answer is Mountain Standard Time (MST). But it’s not that simple. Not anymore.
Until a few years ago, Cabo played the daylight savings game just like the United States. You’d spring forward, you’d fall back. Then, the Mexican government decided they were done with the hassle. In October 2022, they mostly abolished Daylight Saving Time (DST) across the country.

The New Reality of Time in Los Cabos
Cabo San Lucas is located in the state of Baja California Sur. This is a crucial distinction. Its neighbor to the north, the state of Baja California (where Tijuana and Ensenada are), follows a completely different set of rules because they want to stay synced with San Diego and Los Angeles.
But Cabo? Cabo marches to its own beat.
Baja California Sur stays on Mountain Standard Time (MST) all year round. They do not shift the clocks. This means that for half the year, Cabo is on the same time as Denver or Phoenix. For the other half, when the U.S. "springs forward," Cabo stays put, effectively aligning with Pacific Daylight Time (PDT).
Confused? You aren't alone.
I’ve seen honeymooners miss dinner reservations at El Farallon because their "smart" watches didn't update correctly. It happens constantly. Technology is great until it hits a border where the legislative rules changed faster than the software patches.
Why the Confusion Persists
There is a weird psychological trick that happens when you fly into SJD (Los Cabos International Airport). You feel like you’ve traveled further west than you actually have. Geographically, Cabo is almost directly south of Alberta, Canada.
Most travelers from California expect a time jump. They don't get one during the summer. If you fly from LAX to Cabo in July, the time doesn't change. You leave at 10:00 AM, you land a couple of hours later, and your watch is still correct. However, if you do that same flight in December, you’ll lose an hour.
The 2022 Law That Changed Everything
The Mexican Congress passed the Law of Time Zones (Ley de los Husos Horarios) because, honestly, the energy savings from shifting clocks were negligible. People hated the disruption to their sleep cycles. Most of Mexico, including Mexico City and Cancun, moved to a "Standard Time" permanent fix.
However, because the border towns rely so heavily on U.S. trade, they kept DST. Since Cabo is at the very bottom of the peninsula, miles away from the California border, the government decided it didn't need to follow the U.S. schedule.
Comparing Cabo to Other Destinations
It’s helpful to look at how what time zone Cabo San Lucas uses compares to other Mexican hotspots.
Take Cancun. Cancun is in the state of Quintana Roo. Years ago, they moved to their own special time zone called "Southeastern Time" to give tourists more sunlight on the beach. They don't change clocks either. This means Cabo is usually two hours behind Cancun.
Then you have Puerto Vallarta. PV is in the Central Time Zone. If you are flying across the Sea of Cortez from Cabo to the mainland, you are almost certainly going to change your watch.
Does Your Phone Know the Truth?
Usually, yes. Your phone pings the local cell towers (Telcel or Movistar) the second you take it out of airplane mode. It should update.
But—and this is a big "but"—if you are using a roaming plan that struggles to grab a signal, or if you’re out on a boat near the Arch, your phone might get confused. I always tell people to manually set their phone to "Mountain Standard Time (No DST)" or specifically select "Chihuahua" or "Mazatlán" as the city reference if Cabo isn't appearing.

Navigating Tours and Reservations
The biggest headache isn't the jet lag; it's the logistics.
Let's say you booked a whale-watching tour for 8:00 AM. The tour operator is definitely on local Cabo time. If your cruise ship or your phone is still clinging to "Home Time," you’re going to be standing on a pier watching the boat disappear into the horizon.
Cruise ships are notorious for this. Many captains prefer to keep "Ship Time," which matches the port of departure (like Long Beach or San Diego). If the ship stays on Pacific Time but Cabo is on Mountain Time, there is a one-hour gap.
Pro tip: Always ask the hotel concierge or the tour guide, "What is the current local time?" Don't trust your Apple Watch implicitly.
The Impact on Your Itinerary
When planning a trip, you need to account for the sun. Because Cabo doesn't do daylight savings, the sun sets relatively early in the summer compared to what you might expect in the northern U.S. or Canada.
In June, the sun sets around 8:00 PM. In December, it’s closer to 5:30 PM.
If you are planning a sunset sail, the operators adjust their departure times weekly to make sure you actually see the sun hit the water. It’s a well-oiled machine, but it requires you to be on the right hour.
Business and Remote Work
For the digital nomads living in Cabo (and there are many now, thanks to the fiber-optic internet being installed in neighborhoods like El Tezal), the time zone is a blessing and a curse.
If you work for a New York company, you are three hours behind. You’re starting your Zoom calls at 6:00 AM.
If you work for a Silicon Valley startup, you’re perfectly aligned for half the year, and an hour ahead for the other half.
It takes a week to get the rhythm down.
A Summary of the Facts
- Official Zone: Mountain Standard Time (MST).
- Daylight Savings: No. Cabo does not observe it.
- UTC Offset: UTC -7.
- Comparison to PST: During U.S. Standard Time (Winter), Cabo is 1 hour ahead of Los Angeles. During U.S. Daylight Time (Summer), Cabo is the same time as Los Angeles.
Actionable Steps for Your Cabo Trip
- Verify your settings: Upon landing, go to your phone’s date and time settings. Turn off "Set Automatically" if it shows the wrong time, and manually select Mountain Standard Time (GMT-7).
- Confirm with the locals: As soon as you check into your resort, look at the clock behind the front desk. That is your source of truth.
- Check tour confirmations: If you booked an excursion through a third-party site like Viator or TripAdvisor, the "meeting time" is always local time. Double-check this if you are coming from a cruise ship.
- Plan for sunset: If you want that perfect Instagram shot at the Arch, check the local sunset time for that specific day. It changes significantly between winter and summer.
- Ignore the "Baja" confusion: Remember that "Baja California" (the northern state) and "Baja California Sur" (the southern state where Cabo is) follow different rules. Don't look at Tijuana's time and assume it applies to you.
The sun is hot, the tequila is cold, and the time really shouldn't matter that much when you're on vacation. But knowing what time zone Cabo San Lucas is in ensures you don't miss the fishing boat or the happy hour. Stick to Mountain Standard Time, keep an eye on your settings, and you'll be fine.
Safe travels.
