The Best Time to Visit Ilha Grande
The short answer: between April and June or between September and October. This is when you'll find the perfect balance between stable weather, affordable prices, and uncrowded beaches. But Ilha Grande is beautiful year-round—each season offers something different. This guide will help you choose the ideal time for the type of experience you're looking for.
Month-by-month weather in Ilha Grande
January and February: rainiest (160 to 178 mm), high temperature of 30°C, peak season with maximum occupancy. March: rainfall decreases, prices begin to fall. April and May: beginning of the best season — 27°C, 80 to 115 mm of rain, excellent value for money. June to August: minimum rainfall (50 to 55 mm), consistently blue skies, but cooler water (21°C), and July sees a peak season due to school holidays. September and October: spring with mild weather, still warm sea and few tourists. November and December: rain returns, prices rise, peak season begins.
High Season vs. Low Season
During peak season (December to Carnival, July, and long weekends), simple guesthouses charge between R$400 and R$900 per night. During the off-season (April to June and September to November), the same rooms cost between R$150 and R$300. The difference reaches 60%. Boat trips have a more stable price throughout the year (R$120 to R$300), but during peak season the boats fill up quickly, and it's essential to book in advance.
The Golden Window: When to Go to Have It All
Second half of May or first half of October.
Outside of holidays, mild weather with sunshine, fewer tourists, prices 30% to 50% below peak season, sea still warm enough for swimming, excellent visibility for diving, and a lower chance of tour cancellations due to weather. If you have flexible dates, these two windows are unbeatable.
Best Months for Each Activity
Boat trips (Half-Day, Paradise Islands): year-round, best sea conditions from April to September. Island Tour and Super South (open sea): April to September, when the ocean is calmer. Acaiá Cave: sunniest months (May to September), as the phenomenon depends on direct sunlight. Hiking trails: May to November, with mild temperatures and dry trails. Diving and snorkeling: June to September, best visibility (up to 15 meters). Private speedboat: any time of year, but better prices outside of peak season.
What to Avoid and Tips for Saving Money
Avoid long weekends if possible (Tiradentes, Corpus Christi, September 7th, October 12th, All Souls' Day, November 15th) — prices double and everything gets crowded. Travel midweek to save 20% to 40% on accommodation. Use the Barcas Rio ferry (R$ 20.50) instead of a speedboat (R$ 75+) — saving 70% on the crossing. Book tours in advance through our website to guarantee the best prices and availability.
