Traveller notes on Ilha Grande in February
Other months in Ilha Grande
Ilha Grande's forum calls June the start of the cooler, drier season — less rain than the summer months, but regulars note it's noticeably cooler for the beach than northern Brazil destinations like Salvador if warmth matters more to you than avoiding crowds. Still one of the better months overall, since the rainier stretch has passed.
