In March in Barcelona you can really tell you are leaving behind Winter, maybe is not so much the temperatures, as they are not completly warm they go from 45 º F at night to to 64º F in the midle of the day (from 8 to 18 in Celsius), but more because of the lenght of the day, we have many more hours of light tan in Winter. In this March we are not expecting many rainy days either, at least not in the first half of the month.
Also we have in March funny activities, maybe they are not a enough reason to visit Barcelona but if you are already in the city in those days it is a good oportunity to see local traditions.
On the 3rd of March there is a popular parade with horses, charriots and floats in Honor of Sant Medir (Saint Emetherius), since 1828, year in which a bakerman that was cured of an illness thanks to this saint, decided to go in procession to Sant Medir hermitage up in the hills north of Barcelona, every year that day there is this popular parade, 6 tones of candy are thrown to people who go to see that.
For me one of the nicest tradition in Barcelona is the one that takes place on the week end of 21-23 of March, that day 65 owners of vintage cars (before 1926) get together in a set place in Barcelona to go to Sitges which is a coastal village 35 kilometers south of the city, they drive on a bending road along the sea and they must be dressed as in the old times as they will have an “elegance contest”. On Monday they also go together to visit an emblematic catalan site. Even if you are not here that week end, from the 3rd to 21st of March you can see 6 of those cars exhibited in a popular shopping center in Barcelona.
Then in March there are two events related to beer. One of them is not really a catalan tradition, but it so happen that Barcelona is full with Irish pubs, so in Saint Patick day (17th of March) there are little parties in all those pubs.
Also in March, on the 13th to 15th weekend we have what is called the Barcelona Beer Festival, this year takes place in a big hall where you can taste 646 artisan beers and of course you can pair beer with one of the exquisite food options available.
And for those of you who likes pastry, this month is the month of the “buñuelos”, a round, soft dove with sugar on top or cream inside.
