Brazil in May: Weather, Crowds & What to Expect

Amazon & The North (Manaus, Belém, Alter do Chão)

Although rainfall begins to taper in May, the region is still humid and warm; Manaus sees frequent but shorter showers and mornings may be misty along tributaries. River levels gradually fall, reopening some forest trails and making short jungle walks possible again; this transition is also when the air slowly clears of the persistent damp smell. Travelers find fewer mosquitoes in certain higher trails, but bring layers for damp evenings and watch for flight delays due to residual storms.

Northeast Coast (Salvador, Recife, Fortaleza, Jericoacoara)

May tends to be drier and slightly cooler along the northern coast; Fortaleza and the beaches of Ceará enjoy steadier trade winds and warm seas, ideal for sailing and kitesurfing. Further south, patches of rain linger in Bahia but tourist towns like Porto Seguro begin to quiet down after high season. This month suits travelers who prefer fewer crowds and pleasant evenings; a light cardigan is useful for coastal breezes at night.

Northeast Interior - The Sertão & Chapadas (Petrolina, Juazeiro, Chapada Diamantina)

May generally marks the tail end of the rainy period in the highlands, leaving waterfalls still strong and cooler, pleasant hiking conditions across plateau trails. The Sertão returns to more arid, dusty conditions away from rivers; daytime heat drops slightly, and nights become comfortable. This is a good month for combined itineraries-riverine towns are accessible and chapada trails remain press-worthy without peak wet-season logistics.

Central-West (Brasília, Pantanal, Cuiabá, Bonito)

May is a prime shoulder month: the Pantanal dries and animals concentrate near the remaining waterholes, producing some of the most reliable terrestrial wildlife sightings-including jaguars-while daytime temperatures moderate. Brasília enjoys cool, dry days ideal for city sight-seeing and the surrounding Chapada dos Veadeiros is comfortable for hikes. Carry sun protection for daytime heat but also a light jacket for cooler nights in highland areas.

Southeast (Rio de Janeiro, São Paulo, Ouro Preto, Paraty)

May signals the approach of true autumn: days become milder in São Paulo and Rio, humidity drops, and cloudless mornings are common - ideal for city sightseeing and Jardim Botânico visits. Serra da Mantiqueira shows cooler mornings and an increasing range of sweaters in the evening, while waterfalls remain pleasant for day trips. This month is good for reduced crowds and more predictable travel times across the region.

The South (Florianópolis, Curitiba, Gramado, Foz do Iguaçu)

May brings noticeable cooling and crisp nights in Curitiba and Gramado; daytime temperatures remain pleasant but frost risk starts to appear in higher inland valleys on clear nights. Beach weather fades on the coast though coastal microclimates like Florianópolis still see mild afternoons. Travelers should pack warmer layers for evenings and consider heading inland for autumn foliage and quieter wineries.
