Best Time to Visit Lençóis Maranhenses [2026]
Start by considering June to August for a lagoon trip, then check the circuits you want to visit. The calendar helps narrow your dates; rainfall, moving dunes and local conditions determine what you will find. A named month does not guarantee full lagoons or clear skies.
Short answer: June–August is a planning window, not a water-level forecast.
Considering April or May? Keep room for rain in the plan and request a recent assessment of the proposed lagoons before choosing your dates. Compare accommodation and excursion quotes for those dates too.
The Lagoon Cycle
Read this as a general seasonal pattern. ICMBio explains that rainfall and dune movement change the attractions, including their names. Conditions differ between years and circuits.
| Period | What Happens |
|---|---|
| Jan | Water levels depend on when the rains return (sometimes there's still kiting in Atins) |
| Feb-Mar | Filling up; honest low season, low prices |
| Apr | Rain can refill lagoons; check the actual circuits |
| May | A month to consider for lagoon trips, allowing for rain |
| Jun-Aug | A starting window for lagoon planning; confirm levels and weather |
| Sep-Oct | Receding water can change the choice of circuits |
| Nov-Dec | Ask which lagoons retain water and what other outings are available |
Month-by-Month Calendar
Use June–August as a starting point, then compare April–May if you can keep the plan flexible around rain. For September–October, ask which lagoons still have water and which circuits are being proposed. February–March is low season, with lagoons in the filling period and low prices; the water in a particular lagoon still needs checking.

Considering April and May
Leave Room for Rain
April and May are worth comparing with the June–August window if you can adapt your outings. Ask about recent rain and the lagoons in the proposed circuit; do not assume they will have reached a fixed level by a particular week.
April:
- Check how the lagoons have responded to that year's rain
- Park green and lush
- Virtually no tourists
- Low-season prices
- It still rains — and the sunset doesn't always show up
May:
- Ask which lagoon circuits are being offered
- Allow for rain when arranging excursions
- Still few tourists
- Recent conditions matter more than the color in an old photo
Planning Around Rain
Rain is part of the lagoon cycle, but its duration and timing vary. Check the forecast close to departure and ask the operator how changes would affect the route, departure and return. Keep some flexibility instead of assuming every shower will pass within an hour.
Low season: February and March can still be worth considering, with fewer tourists and lower prices. Choose using recent information about the places you want to visit. January's lagoon conditions also depend on the return of the rains; do not assume every lagoon is dry or already filling.

How Much It Costs
Prices vary by village and how far in advance you book.

|---|---|---|
| Atins | R$330–850+ (luxury R$2,000+) | full day ~R$240 · half ~R$120 (Jun/2026) |
| Barreirinhas | R$70–250+ | varies |
| Santo Amaro | varies | varies |
*Guesthouse figures are indicative for 2026; they vary a lot with how far in advance you book and the season.
The difference: In high season (Jul-Aug), lodging can cost 2-3x the low-season price.

Frequently Asked Questions
What's the best month to visit Lençóis Maranhenses?
Start with June to August for a lagoon trip. April and May are also worth comparing if you can allow for rain. Confirm recent conditions on the circuits you want; no month guarantees full lagoons or clear skies.
Are the lagoons already full in April?
They may have accumulated water, but the answer depends on that year's rain and the lagoon. Ask about the specific circuits for your dates rather than relying on a fixed percentage for April or May.
Is it worth visiting Lençóis in the low season?
It can be. February and March fall in the filling period, with fewer tourists and lower prices. For September, check which lagoons retain water and which outings are proposed; there is no reliable fixed percentage for the whole park.
When do the Lençóis lagoons dry up?
The timing differs between lagoons and years. Do not treat September as a universal start date: in July 2026, ICMBio already announced Jacundá as an alternative following drainage at Bicudo Gordo. That dated example explains why you need a current assessment; it is not a report of today's water levels.
