As of today, peak season now, through ~July 10. Earth Exhibit tracks the live conditions and flags it the moment it is on.
Each year reef groupers form dense spawning aggregations in the South Pass (Passe Sud) of Fakarava Atoll, Tuamotu Archipelago.
Dives during the seasonal peak offer chance to observe hundreds to thousands of groupers gathering and releasing gametes in strong tidal flows, a behavior tightly linked to the lunar cycle and currents.
