In August, the ‘Garua’ or dry Season is at its peak now making August (and September) the coolest months in Galapagos (though still pleasant with highs of 24 °C and lows of 19°C) seas are also cool and rough in these months.
The Cromwell Current and South Equatorial Current, the cold water currents that bathe Galapagos are in full effect which means nutrient-rich water is brought to the ocean surface, making marine life in the Galapagos is very active. Although the water is cooler, snorkelling good due to the level of underwater activity.
August is a good month to have chances to see whales and dolphins, especially in the southern, western and northern parts of Isabella, as well as the south eastern parts of Galapagos.
Sea bird communities are very active and the abundance of food for marine life, means it is a good time for female sea lions to deliver their pups as food is within easy reach of their nursing territories. They can been seen across the archipelago.
