Pororoca Day, also known as Pororoca Great Roar Day, is the day when the ocean tides are the highest in the Amazon river estuary due to the full moon each March and February.

On these days, the powerful Pororoca wave is born as the 'tidal bore' that reverses the Amazon river flow and travels upstream for many miles.

Pororoca translates as 'the Great Roar' from local Tupi languages and its power has been feared and celebrated by the local communities for many generations.

In recent years, the Pororoca Day has been celebrated as the Day of Simultaneous Non-violent Civil Art-actions promoting equality, unity and peace among all nations and cultures, small and large, across the globe.

Public presentations advocating peace and justice take place simultaneously around the world at the precise time of the March full moon as it appears in the Amazon River estuary (of Brazil's Amazon Time Zone).
