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 stretch out and the sun has a bit more bite. For those of us living in this city, the shift is inevitable: the green juice stalls get busy, people drag their bikes out of storage, and most importantly, 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 keen to soak up some of that good energy.

The sun dances on the pyramids: Chichén Itzá and Teotihuacán

If there are two spots that become ground zero for the solar celebrations, it's the Yucatán Peninsula and the State of Mexico. At Chichén Itzá, the light and shadow play on El Castillo is the show everyone wants to catch. Although the feathered serpent, Kukulkán, puts on its best performance during the spring equinox (and also the autumn one), the reality is the archaeological site gets packed with visitors coming to welcome the new cycle. For 2026, the INAH has its plan ready to handle the influx, with special timings 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 Pyramid of the Sun just as spring kicks off has a certain magic to it, even if it's just to realise your legs aren't what they used to be. Last year, over 40,000 people turned up at the site in a single day, so you can imagine the scene. For the spring equinox 2026, access to the monuments will be managed. Don't get caught out: arrive early, because they open before sunrise, but by the time the clock hits 10 am, 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 question that always comes up: why doesn't the equinox fall on the exact same day every year? We can blame our trusty, slightly 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. This 2026, the equinox officially falls on Friday, March 20, although the celebrations and energetic cleanses will stretch right through the weekend.

Unlike more American traditions like Groundhog Day, which only predicts whether winter will drag on, for many cultures this moment is a real 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.

A survival guide for the equinox (without coming to grief)

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 need to follow if you don't want to get sunstruck or slapped with a fine. The INAH has been pretty clear this season:

• Arrive early: At Teotihuacán, gates open from 8:00 am, but I'd recommend getting there before then. Access to the Pyramid of the Sun usually closes once it hits capacity.
• Clothes and footwear: Don't be that person trying to climb the pyramid in jandals and a floppy hat that flies off at the slightest breeze. Wear sneakers, bring water and sunscreen, even if it's cloudy.
• Respect the site: This isn't the 90s anymore. It's strictly forbidden to go up with glass bottles, film with professional gear without a permit, or, obviously, try to take away little rocks "as a souvenir".
• Ceremonies: You'll see dance groups, people with crystals, and some colourful characters. It's all good, but don't join in unless you're invited. The vibe is powerful, but respect comes first.

The heat is coming

Mysticism aside, the hard facts are that after this spring equinox 2026, we're in for a Summer that promises to be a real sweatfest. The climate experts are 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 feel the sun on our faces during the equinox, we also need to brace ourselves for power cuts and the ice running out at the local dairy.

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 own rooftop, March 20 is a good excuse to believe that everything can start again. See you at Teotihuacán at sunrise.
