የIlha Grande አየር ሁኔታ በጁን

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.

Regulars are specific this counts as the coolest, driest part of the year here, genuine winter in Rio state though nothing close to actually cold, pleasant temperatures the norm throughout. Our row backs that cool, genuinely wet read, 16.8C over 13C nights feeling 12C, with 76.7mm of rain across 9.7 days and humidity at 78 percent. Regulars are consistent most bars, restaurants and pousadas stay open despite the island being noticeably quieter, prices running lower and weekends specifically more lively than weekdays. Windy conditions can make scuba diving less reliable this month even though most other activities stay unaffected. The sea sits at a mild 22.9C. The record: 8.5 hours of sun, a 14 kph wind and AQI 65.

Regulars genuinely disagree on this month: one names it great weather, with the heaviest rain confined to December through March and already behind by now, while another calls it a poor choice specifically for a beach-and-forest island because tropical rain is still a real risk. Our row backs the wetter view more than the drier one, a real 145.3mm of rain across 14.5 days, alongside mild-for-Brazil temperatures, 19.3C over 16.4C nights. Regulars broadly agree this and the other shoulder months, April through June and September through November, offer the best balance of decent weather, thinner crowds and lower prices compared with the December-March peak. The sea holds a warm 25.9C regardless of the air. The record: humidity 80 percent, 9.3 hours of sun, a 12.2 kph wind and AQI 62.

Regulars say May and June are not much of a rainy season on this stretch of coast, with one caveat attached: you can be unlucky and land on a cold front, which brings overcast and drizzle for its duration. One visitor here from late April into May reported the rain confined to a few days and the sunny ones hot but not excessively. Our row is cooler than that suggests - 17.9C days over 14.8C nights, the sea still holding 24.7C from the summer - with 77.6mm across 10.8 days and 9 hours of sun. On crowds, this is the quiet half of the year, mostly travellers rather than holidaymakers, though weekends fill and mid-May is the sweet spot. No cars on the island, so the trails are the point. The record: humidity 79 percent, a 12.1 kph wind and AQI 57.

September is the end of the cooler, drier winter run regulars date from June, and a first-week visitor describes good atmosphere without crowds. A caution about our own figures: the 17.8C here reads far cooler than anyone describes the beaches, because the grid square takes in the island's forested high ground rather than the shore - the 24.1C sea is the number to trust for Lopes Mendes and Abraao. What the month does carry is 76mm across 11.2 precipitation days, and the island's best day out depends on it: the four-beach boat trip runs to Praia do Pouso and then a forest trek to Lopes Mendes, and needs decent conditions. Abraao is where you wait one out. The record: humidity 81 percent, 9.5 hours of sun and AQI 76.
