The seasons on the island

Season	What it is usually like	Good for
Summer (Dec. to Mar.)	hot and humid, pleasant sea, crowded island and slow traffic	beach lovers who like a buzz
Autumn (Mar. to Jun.)	mild days, fewer people, sea still good early on	beach time without the crowds
Winter (Jun. to Sep.)	cool, south wind, cold sea	hiking, food, culture
Spring (Sep. to Dec.)	warming days, quieter until November	hiking and peaceful beaches

High season

From Christmas to Carnival, the island receives many Brazilian and foreign tourists, especially Argentines, Uruguayans and Chileans. Accommodation gets more expensive, restaurants fill up and roads such as the SC-401 in the north, as well as the routes in the south and east, jam up.

Winter is worth it too

With the sea cold, winter is the season for hikes such as the Lagoinha do Leste trail, for food and for the Azorean villages. It is also when the south wind clears the air for photos of the Hercílio Luz Bridge.

Rain

It rains in every season. Have a plan B: see Florianópolis on a rainy day.
