Spring Equinox 2026: Timings, Archaeological Sites & 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 getting longer and the sun is packing more of a punch. For those of us living in this city, the change is inevitable: the green juice stalls are bustling, people are pulling their bikes out of storage, 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 festivities, they are the Yucatán Peninsula and the State of Mexico. At Chichén Itzá, the light and shadow phenomenon 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 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 plans ready to manage the influx of people, with special timings that are always worth checking before you make the trip.

On the other hand, Teotihuacán remains the all-time favourite for locals from Mexico City and the central part of the country. Climbing the Sun Pyramid just as spring begins has a touch of 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 visited the archaeological site in a single day, so you can imagine the crowds. For the spring equinox 2026, access to the monuments will be controlled. Don't be caught off guard: 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 Groundhog Day 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 the exact same day every year? The blame lies with our beloved and somewhat 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, 20 March, although the celebrations and energy 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 festival with over 3,000 years of history where the focus is on cleaning the house, visiting family, and, just like here, welcoming the rebirth of the earth.

Survival Guide for the Equinox (Without Conking Out)

Look, whether you're heading to the pyramids or just want to feel the change of season at a city park, there are unwritten rules you need to follow if you don't want to get sunstroke 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'd recommend getting there before. Access to the Sun Pyramid usually closes once it reaches maximum capacity.
• Clothing 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: It's not the 90s anymore. Climbing with glass bottles, filming with professional equipment without a permit, or obviously, trying to take little stones "as souvenirs" is completely forbidden.
• Ceremonies: You'll see dance groups, people with crystals, and colourful characters. It's cool, but don't just join in if you're not invited. The vibe is powerful, but respect comes first.

The Heat That's Coming

Mysticism aside, the hard truth is that after this spring equinox 2026, we're in for a Summer that promises to be a real sweat-fest. 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 feel the sun on our faces during the equinox, we also need to brace ourselves for power outages and ice running out at the convenience store.

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