These islands, because of their privileged geographical position and mountainous relief, have a surprisingly mild climate. Very mild average temperatures, 22ºC in the summer and 16ºC in the winter, and a moderate level of humidity, confer upon these islands exceptional subtropical features. The seawater temperature is also very mild, because of the influence of the warm Gulf current, presenting averages of 22ºC in the summer and 18º in the winter.
