July falls into the cool and dry season, where southern trade winds carry the cold Humboldt and Cromwell currents past the Galapagos Islands. The air and ocean are both cooler during this time, the skies are generally more overcast, and a sea mist rises to the highlands. In the cool and dry season, the sun is less intense, light tropical rains can fall and the increase in wind brings choppier seas. The average temperature in July is between 19-26ºC.
Throughout July, the islands are cool and occasionally drizzly while still holding on to the sunshine and clearer skies of the warm and wet season – however it is also one of the windiest months. On the wildlife front, lava lizards begin to initiate mating rituals (which continues through to November) and flightless cormorants perform their beautiful courtship rituals and nesting activities on Fernandina Island. This is the ideal time to witness the four nesting stages of blue-footed and Nazca boobies, from eggs and chicks to juveniles and sub-adults. Sightings of whales and dolphins are more likely, especially off the western coast of Isabela Island, since the strong currents carry large amounts of plankton. Near Darwin and Wolf Islands whale sharks can be spotted, and greater flamingos begin their courtship dances.
