Rain days are the days with at least 1 mm of rain, as a weather station counts them.

Weather read at Barreirinhas, the gateway town: ten years of ERA5 and ERA5-Land reanalysis, through Open-Meteo's open data.

A busy month is a crowded one, not a bad one — usually it is crowded because the weather is good. It is flagged rather than scored down, and crowds alone never make a month “avoid”: that is reserved for weather worth skipping.

How busy it gets

Busiest in January, July and August; quietest in April, May and September.

Getting there

Fly into São Luís (SLZ), then drive. The flights under Where to book are to São Luís.

The drive from each airport is the road's, from openrouteservice.org by HeiGIT: typical, not a schedule.

How far Lençóis Maranhenses is, and what it costs, depends on where you set off from — the months above do not.

Before you go

Type C plugs at 127 / 220 V. Drives on the right. The currency is the Brazilian real. UK Foreign Office: avoid all but essential travel to parts. Everything for Brazil: cost of living, languages, emergency numbers and health.

Being there

On arrival

Paying — Most businesses take cards, and in big cities cash is used less and less. Locals pay by Pix, which needs a Brazilian bank account or CPF.
UPI, for visitors from India — Not accepted for paying here; bring a card that works abroad.
Tipping — A 10% service charge is usually on the restaurant bill, so nothing more is needed; taxi drivers do not expect a tip, though people may round up.
