- Land iguana eggs hatch on Isabela.
- Green sea turtle eggs begin to hatch.
- Massed ranks of waved albatross arrive on Espanola to begin their amazing courtship ritual.

September
- Peak of the garua season and the ‘coldest’ month in the Galapagos with temperatures down to below 20C and sea mist a frequent occurrence.
- Female sea lions have reached oestrus stage, so harem-gathering males are constantly barking and fighting.
- Galapagos penguins are remarkably active around Bartolome and are a delight to snorkel with as they torpedo through the water.

- Blue-footed boobies raise chicks all over Espanola and Punta Vicente Roca (Isabela).
November
- Transitory period from one season to the next with good weather, decreasing winds, calm seas and slowly rising water temperatures - so excellent conditions for snorkelling.
- End of the sea lion pupping season.
- Sea lion pups (especially at Champion Islet, Floreana) perform aqua-aerobics next to snorkellers and are often curious enough to nibble at their fins.
- Physalia jellyfish can often be seen in Gardner Bay (Espanola) and Caleta Tortuga (Santa Cruz).
- Band-rumped storm petrels begin their second nesting period.
- Breeding season for the brown noddy.
