If you’re planning a trip to Mazatlán or heading to Culiacán for business, you’ve probably checked your phone and wondered why the clock looks... well, a little weird compared to what you expected. Honestly, time in sinaloa mexico used to be a headache for everyone involved.
For years, travelers and locals alike had to deal with the "spring forward, fall back" ritual that messed with sleep schedules and flight times. But everything changed in 2022. Mexico’s federal government decided they’d had enough of the "summer schedule" (horario de verano). Now, as we move through 2026, the rules are different, and if you're looking at old travel guides, you're definitely going to get it wrong.
The One Thing You Need to Know: No More Clock Changes
Basically, Sinaloa doesn't do Daylight Saving Time anymore. Period.
Back in October 2022, the state moved its clocks back for the last time. Since then, the entire state has remained on Mountain Standard Time (MST) year-round. It doesn't matter if it's the middle of July or the dead of winter—the time in Culiacán is the same as the time in Mazatlán and Los Mochis.
This is actually a pretty big deal for the lifestyle here. You don't have that jarring week in April where everyone is grumpy because they lost an hour of sleep. The sun rises and sets according to "God's Time," as President Andrés Manuel López Obrador famously called it when he pushed for the change.
How Sinaloa Compares to the Rest of the World
Because Sinaloa stays put while other places move, your relative time difference is going to shift twice a year.
- With New York (EST/EDT): In the winter, Sinaloa is 2 hours behind. In the summer, when New York "springs forward," Sinaloa is 3 hours behind.
- With Denver/Arizona (MST/MDT): This is where it gets tricky. Arizona doesn't change clocks either. So, for most of the year, Sinaloa and Arizona are perfectly synced. But if you’re looking at Colorado or Utah, they’ll be an hour ahead of Sinaloa during the summer.
- With California (PST/PDT): In the winter, Sinaloa is 1 hour ahead of Los Angeles. In the summer? You’re actually on the exact same time.
It’s kinda wild to think that Mazatlán can be on the same time as Hollywood one month and then suddenly be ahead the next, without ever actually moving its own clocks.
Why Does This Matter for Travelers?
If you're booking a flight, pay close attention to your arrival time. Most modern smartphones are smart enough to update automatically based on GPS, but if you have "Set Automatically" turned off, you are asking for trouble.

I’ve seen people miss the famous "Sunset at the Malecón" because they thought they had an extra hour. They didn't. In the summer months, the sun sets around 8:00 PM in Mazatlán. In the winter, it’s closer to 5:30 PM.
The Business of Time in Culiacán
Culiacán isn't just a stopover; it’s a massive hub for agriculture and business. If you’re coordinating a Zoom call with a partner in Mexico City, remember that Mexico City is in the Central Time Zone.
Sinaloa is always one hour behind Mexico City.
When it's noon in the capital, it's 11:00 AM in Culiacán. This is a fixed rule now. You don't have to check if it's "summer time" or "winter time" to figure out the gap between the two. It stays a one-hour difference 365 days a year.
Debunking the Border Confusion
A common misconception is that all of Northern Mexico follows the U.S. daylight savings schedule. That’s just not true. While cities right on the border—like Tijuana, Mexicali, and Ciudad Juárez—do still change their clocks to stay in sync with their American neighbors for trade reasons, Sinaloa does not.
Sinaloa is a Pacific coastal state, but it technically sits in the Mountain Time Zone. People often assume because it's on the coast, it should be on Pacific Time. Nope.
Real-World Advice for Navigating Sinaloa Time
If you’re on the ground, here is how you keep your life simple.
First, trust your phone, but verify with the hotel front desk the second you check in. Just a quick "Qué hora es?" goes a long way. Second, if you are driving in from a state like Chihuahua or moving toward Nayarit, double-check those borders. Nayarit also abolished DST (except for one specific municipality, Bahía de Banderas, which stays on Central Time to match Puerto Vallarta), so the transition is usually smooth.
The most important takeaway for 2026 is that the "summer schedule" is a ghost of the past. Sinaloa has embraced a permanent, slower rhythm. It matches the vibe of the state—less rushing, more enjoying the heat.
Actionable Next Steps:
- Check your device settings: Ensure your time zone is set to "Mexico/Mazatlan" rather than just a generic "Mountain Time" to ensure it respects the no-DST rule.
- Adjust your dinner plans: If you're visiting in the winter, remember that the sun disappears early. Book those ocean-view tables for 5:00 PM if you want the view.
- Confirm transport: Double-check bus and ferry schedules (like the Baja Ferries to La Paz) as they operate on strict local time, which may differ from your point of origin if you're coming from the U.S. or Baja California.
