December does something to Madrid. The city loosens up, the lights go on, and the whole place seems to lean into the last stretch of the year. If you're deciding where to see out 31st December, honestly, you could do a lot worse than the Spanish capital. Locals and visitors end up sharing the same streets and squares, and there's plenty going on, from the old-fashioned Christmas markets to the New Year's Eve parties that run well past midnight. Here's how the night tends to unfold, and a few ways to make it yours.

So what actually is the 31st of December about?

It's the last day of the year, which sounds obvious, but in Madrid it carries a bit of weight. People gather with family and friends, look back on the twelve months just gone, and get ready for whatever comes next. The traditions are half the fun. The big one is eating Twelve Grapes at Midnight, one for each chime of the clock, which is meant to set you up with good luck for the year ahead. Beyond that, some people go to mass, some set off fireworks, and plenty just stay up to catch the countdown on TV. No two households do it quite the same way.

What's the mood like in Madrid on the night?

Festive, loud, warm-hearted. People come together over food, drink, music and dancing, and there's this real sense of community as the countdown gets closer. When midnight finally hits, everyone raises a glass and greets the new year together. Standing in the middle of it, you'd struggle not to join in.

Things to do in Madrid on 31st December

Plenty of options here, and they suit different kinds of night. If you're after the classic experience, head to the Puerta del Sol. It's one of the busiest squares in the city and it's where the main New Year's Eve celebrations happen. My advice? Get there early in the evening. It fills up fast and later on it's genuinely packed.

Prefer to dance the year out? Madrid's clubs and bars stay open into the small hours, and it's a brilliant way to party your way into 2019. Just pace yourself, drink responsibly, and don't overdo it. You'll want to actually remember the night for the right reasons.

And if a quieter, more cultural evening is more your speed, you could always spend part of the night in one of the city's many museums or art galleries.

How the day plays out, from afternoon to midnight

The 31st is a proper occasion in Madrid. Every year the city sends off the last day with a big celebration, and people travel from all over the world to be part of it. Music, food, drink, the works.

Out on the streets you'll find crowds everywhere, a bit of a charge in the air, and music drifting from more or less every corner. You'll even spot people in traditional Spanish dress, like the white shirt and red scarf you'd associate with bullfighters.

Food and drink matter a lot here. Spanish staples like paella and tapas get passed around during the festivities, and the drink of choice for many is sangria, that red wine punch you can happily nurse for hours.

At midnight, Madrilenos tuck into a traditional dish of lentils and bacon, which is said to bring good luck for the year to come. Once that's done, a lot of people make their way to Puerta del Sol, one of the city's most iconic spots, to watch the New Year's Eve countdown.

The traditions worth knowing about

One lovely one: the 31st is the night when the city's 'parejas', the couples, come out to celebrate. The idea is for couples to stroll arm in arm around the city center, pausing at different landmarks for photos and to soak up the atmosphere. The favourite stops tend to be the Puerta del Sol, Plaza Mayor and the Cathedral of Madrid.

It's a family night too. Plenty of people head to their local church or chapel for Midnight Mass, then go home for a special meal together. For a lot of families, the high point is the traditional New Year's Eve fireworks at midnight, set off in front of the Royal Palace.

How the celebration has changed over the years

The 31st in Madrid has shifted over time from a religious holiday into something more secular. It used to be marked with mass and a procession to the city's cathedral. These days it's more about seeing out the last night of the year with the people you love. Most folk spend the evening eating and drinking, then spill out into public squares and parks to catch the fireworks at midnight.

Final thoughts

If you find yourself in Madrid on December 31st and you want a good night out, you won't have to look hard. There are events all over the city, from music concerts to street parties, and they cover pretty much every mood. If you do one thing, catch the fireworks at midnight. Years later, that's the bit you'll still be talking about.
