Spring Equinox 2026: Timings, Archaeological Sites, and What to Expect as Winter Ends in Mexico

You can already feel it in the air. After the bone-chilling cold and wind, the days are starting to get longer and the sun feels stronger. For those of us living in this city, the change is inevitable: the green juice stalls get busy, people pull their bikes out of storage, and above all, we start planning that ritual getaway. We're just about at the spring equinox 2026, and like every year, the archaeological sites are gearing up to welcome thousands of people looking to soak up some of that good energy.

The sun dances on the pyramids: Chichén Itzá and Teotihuacán

If there are two places that become the epicentre of the solar festivities, they are the Yucatán Peninsula and the State of Mexico. At Chichén Itzá, the light and shadow play on El Castillo is the show no one wants to miss. Although the feathered serpent, Kukulkán, puts on its best performance during the spring equinox (and also in autumn), the reality is the archaeological site fills with visitors coming to welcome the new cycle. For 2026, the INAH's plan is ready to handle the rush of people, with special timings that are always worth checking before you make the trip.

On the other hand, Teotihuacán remains the absolute favourite for people from Mexico City and the central part of the country. Climbing the Pyramid of the Sun just as spring begins has something magical about it, even if it's just to realise your legs aren't what they used to be. Last year, over 40,000 people arrived at the site in a single day, so you can imagine the crowd. For the spring equinox 2026, access to the monuments will be controlled. Don't be too casual about it: arrive early, because they open before sunrise, but by 10 in the morning, the queues to climb are already worthy of a Rolling Stones concert.

From groundhogs to the Persian calendar: What's the deal with the dates?

Here's the same question that always comes up: why doesn't the equinox fall on exactly the same day every year? The blame lies with our beloved and messy Gregorian calendar. While nature follows its own rhythm with Autumn, Summer, and the rest of the seasons, we humans insist on trying to fit everything into leap years. In 2026, the equinox will officially fall on Friday, March 20th, although the celebrations and spiritual cleansings will stretch throughout the weekend.

Unlike more American traditions like Groundhog Day, which only predicts if winter will drag on, for many cultures this moment is a turning point. In fact, academically speaking, the equinox marks the new year in the Persian calendar, known as Nowruz. It's a celebration with over 3,000 years of history where the idea is to clean the house, visit family, and just like here, welcome the rebirth of the earth.

Survival guide for the equinox (without dying in the attempt)

Look, whether you head out to the pyramids or just want to feel the change of season in a city park, there are unwritten rules you should follow if you don't want the sun to get to you or end up with a fine. The INAH has been clear for this season:

• Arrive early: At Teotihuacán, gates open from 8:00 AM, but I recommend getting there before. Access to the Pyramid of the Sun usually closes once it reaches maximum capacity.
• Clothes and footwear: Don't be that person trying to climb the pyramid in flip-flops and a wide-brimmed hat that flies off with the slightest breeze. Wear trainers, bring water and sunscreen even if it's cloudy.
• Respect the site: We're not in the 90s anymore. It's completely forbidden to climb with glass bottles, film with professional equipment without permission, or obviously, try to take away little stones "as a souvenir".
• Ceremonies: You'll see dance groups, people with crystals, and colourful characters. It's cool, but don't join in if you're not invited. The energy is powerful, but respect comes first.

The heat that's coming

Putting the mysticism aside, the hard fact is that after this spring equinox 2026, we have a Summer ahead that promises to be a real sweat-inducer. Climatologists are already sharpening their pencils, but those of us living in this concrete jungle know that the heat from March to June is a beast. So, while we get ready to welcome the sun on our faces during the equinox, we also brace ourselves for the power cuts and the ice that runs out at the corner store.

Enjoy the end of winter, find your best white outfit (for tradition's sake) and remember: whether it's at the archaeological site or on your rooftop, March 20th is a good excuse to believe that everything can start again. See you at Teotihuacán at sunrise.
