Beaujolais Day is a huge celebration in Swansea and thousands of people dressed to the nines will be heading to events organised across the city.
Officially, the day is a celebration of the first wine of the season made from the first harvest of grapes in the Beaujolais region of France.
Swansea has embraced the day, which this year falls on November 21, and is arguably the place to be if you are planning on sinking a few glasses.
In reality, though, as far as Swansea is concerned, that third Thursday in November is the launch of the Christmas party season, with the date circled in many a diary for months in advance.
Here are just some of the bars and restaurants in Swansea celebrating Beaujolais Day in style.
The party usually starts at lunchtime and continues well into the night.
But if you are in Swansea for the day then make sure you pack an umbrella as there is a high chance of rain.
Met Office forecaster Oli Claydon said: "From 4am on Thursday it will be a dry start. Wind levels will be fairly consistent throughout the day.
"Unfortunately, rain will then start to move in from the West. From 7am-8am there could be a light break out of rain but the rain will get heavier as the day goes on and this will last into the evening.
"The morning will be the best chance of staying dry - the temperature will be quite chilly and there will be highs of 9°C."
