Spring Equinox 2026: Times, 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 warmer. For those of us living in this city, the shift is undeniable: green juice stands are busier, people are dusting off their bikes, and most importantly, we're starting to plan that ritual getaway. We're just around the corner from 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 celebration, it's the Yucatán Peninsula and the State of Mexico. At Chichén Itzá, the light and shadow effect on El Castillo is the show no one wants to miss. Although the feathered serpent, Kukulkán, puts on its best display during the spring equinox (and also the autumn one), the reality is that the archaeological site fills up with visitors coming to welcome the new cycle. For 2026, the INAH has its plan ready to handle the crowds, with special hours that are always worth checking before you make the trip.

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

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

There's always the same question: why doesn't the equinox fall on the exact same day every year? The blame falls on our dear, messy Gregorian calendar. While nature follows its own rhythm with autumn, summer, and the rest of the seasons, we humans insist on trying to square everything with leap years. This 2026, the equinox will officially fall on Friday, March 20, although the celebrations and energy cleanses will stretch throughout the weekend.

Unlike more American traditions like Groundhog Day, which only predicts whether 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 it's all about cleaning the house, visiting family, and, just like here, welcoming the rebirth of the earth.

Survival guide for the equinox (without wiping yourself out)

Look, whether you're heading 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 to get hit by the sun or land yourself a fine. The INAH has been clear for this season:

• Arrive early: At Teotihuacán, gates open at 8:00 a.m., but I'd recommend getting there before. Access to the Sun Pyramid usually closes once it reaches max capacity.
• Clothes and footwear: Don't be the fool who tries to climb the pyramid in flip-flops and a wide-brimmed hat that flies off at the slightest breeze. Wear sneakers, bring water, and pack sunscreen even if it's cloudy.
• Respect the site: We're not in the '90s anymore. It's strictly forbidden to go up with glass bottles, film with professional equipment without a permit, or, obviously, try to take little rocks home "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 haven't been invited. There's some incredible energy, but respect comes first.

The heat that's coming

Mysticism aside, the hard fact is that after this spring equinox 2026, we're in for a summer that promises to be a real sweaty one. 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, as we get ready to welcome the sun during the equinox, we also brace ourselves for power outages and the corner store running out of ice.

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