The diving season is divided into two parts: June-November and December-May periods. The June-November season is considered to be the best as more marine life can be seen. This is due to the fact that Humboldt current brings in substantial amounts of plankton, which attracts the fish and affects the sea life. However, if you are planning to dive during this season pay attention to the fact that the water temperature will be lower and you will need respective clothing. The December-May season with warm water and sunny weather is more pleasant all round the Galapagos.
