Paraty in January

April through September offers the sweet spot — less rain, fewer crowds, and temperatures that hover around 24°C. The Atlantic Forest stays green year-round, but you'll actually see the mountains without cloud cover during these months. July brings the Festival de Inverno, when the town fills with musicians and the cobblestone streets become concert venues. Hotel prices double, but the energy is infectious. Book accommodations three months ahead if you're coming during festival season. Avoid December through February unless you enjoy sharing narrow streets with thousands of other visitors. The summer rains turn the historic center into a steam bath, and finding a restaurant table without a reservation becomes nearly impossible. March and October sit in the shoulder season sweet spot. You'll get decent weather with manageable crowds, plus hotel rates drop by 30-40%. The sea temperature stays warm enough for swimming year-round — around 23°C even in winter.
