September marks the transition between the gara (dry season) and the warm season in the Galpagos Islands. Air temperatures begin to rise, typically ranging from the low 70s (F) to the low 80s (F), while water temperatures hover around 72F. Ocean currents shift, bringing warmer waters and often calmer seas. This transitional period often experiences a mix of sunshine and overcast skies, with occasional showers possible.
Understanding these specific climatic conditions is crucial for visitors planning a trip during this month. The changing ocean currents influence marine life behavior and visibility for activities like snorkeling and diving. The warmer waters attract different species and create unique underwater encounters. Furthermore, the generally calmer seas can make boat trips more comfortable. Historically, this period signifies a shift in the islands’ natural rhythms, impacting both terrestrial and marine ecosystems.
