Tide for Kite
Tide is very influential on kite conditions at north Brazil. Water conditions at sea and beach size change with tide. Some lagoons like Ilha do Guajiru don't have enough water for kite at low tide. Some kite spots like Paracuru and Barra Grande have flat conditions only on low tide. So when you go to a kite trip, plan according to tide tables.
