About Pororoca of the Capim River
The pororoca of the Capim River is the wave formed when the tide rises up the river against the current. Atlantic water enters through the Guajará Bay, flows past Belém, advances along the Guamá River and, near São Domingos do Capim, about 180 km from the sea, meets the descent of the Capim. The difference in level becomes a front of water that runs upstream with a roar.
The wave is larger on spring tides, at full and new moon, when the difference between high and low tide is greater. The strongest period runs from the start of the year until May, when rivers are full, and peaks usually occur in March and April. The Capim wave rarely exceeds two meters, but it lasts for long stretches.
Since the late 1990s surfers have ridden the Capim pororoca, and the Pororoca Festival brings together surfing, canoeing and endurance competitions, carimbó performances and Pará food stalls. There are attempts at records for most surfers on the same wave and night rides.
For those who just want to watch, the riverbank in front of the town is the most popular spot. First you hear the noise; then the wave arrives, lifts anchored boats and proceeds upstream.
Before you go
Practical information
Cidade Turismo reviews its information regularly, but something may have changed. Check with the place before planning your trip.
How much time to set aside
The wave’s passage lasts only a few minutes; allow 1 to 2 hours and arrive before the tide’s scheduled time.
Best time
In the first half of the year, between January and May, on spring tide days; March and April usually have the highest waves. The time changes daily with the tide; ask locally in town.
How to get there
The pororoca passes in front of the town, on the Capim River, near its meeting with the Guamá. From the bus station and downtown, walk to the riverbank.
Tip
Arrive well before the scheduled time, stay away from the edge and from anchored boats, and watch children: the wave lifts the water suddenly. Enter the river only with someone who knows the place.
