Spring Equinox 2026: Timings, archaeological sites, and what to expect as winter ends in Mexico

You can feel it in the air already. After the cold and the wind that cuts right through you, the days are starting to stretch out and the sun has a bit more of a kick. For those of us living in this city, the shift is hard to miss: the green juice stands are doing a roaring trade, people are digging the bikes out of the shed, and above all, we're starting to plan that ritual getaway. We're just on the cusp of 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 absolute epicentre of the solar party, it's the Yucatán Peninsula and the State of Mexico. At Chichén Itzá, the light and shadow play on El Castillo is the show nobody wants to miss. While the feathered serpent, Kukulkán, puts on its best performance during the spring equinox (and also the autumn one), the reality is the site gets packed with visitors coming to welcome the new cycle. For 2026, the INAH has its plan ready to manage the crowds, with special opening times that are always worth checking before you make the trip.

On the other hand, Teotihuacán remains the firm favourite for people from Mexico City and the centre of the country. Climbing the Pyramid of the Sun just as spring begins 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 descended on the site in a single day, so you can imagine the buzz. For the spring equinox 2026, access to the monuments will be controlled. Don't be caught out: get there early, because they open before sunrise, but by the time the clock hits 10 in the morning, the queues to go up are already worthy of a Rolling Stones concert.

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

There's always the same confusion here: why doesn't the equinox fall on the exact same day every year? You can blame our beloved, slightly chaotic Gregorian calendar. While nature follows its own rhythm with Autumn, Summer, and the rest of the seasons, we humans insist on trying to square it all with leap years. In 2026, the equinox officially falls on Friday, 20 March, although the celebrations and spiritual cleansings will stretch right across the weekend.

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

Your survival guide for the equinox (without coming a cropper)

Look, whether you're heading to the pyramids or just want to feel the change of season in a city park, there are some unwritten rules you need to follow if you don't want to get caught out by the sun or land yourself with a fine. The INAH has been pretty clear for this season:

• Get there early: At Teotihuacán, gates open from 8:00 am, but I'd recommend getting there before that. Access to the Pyramid of the Sun usually closes once it hits full capacity.
• Clothes and footwear: Don't be that eejit who tries to climb the pyramid in flip-flops and a wide-brimmed hat that takes off in the slightest breeze. Wear trainers, bring water and slap on the sun cream even if it's cloudy.
• Respect the site: We're not in the 90s anymore. It's absolutely banned to go up with glass bottles, film with professional gear without a permit, or, obviously, try to nick little stones "as a souvenir".
• Ceremonies: You'll see dance groups, people with crystals, and some colourful characters. It's sound, but don't join in if you haven't been invited. There's a powerful energy, but respect comes first.

The heat that's on the way

Mysticism aside, the hard facts are that after this spring equinox 2026, we've got a Summer coming that promises to be a real sweaty one. 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 fierce beast. So, while we get ready to feel the sun on our faces during the equinox, we're also bracing ourselves for the power cuts and the ice running out in the local shops.

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