May falls within the shoulder season in French Polynesia, marking the transition from the humid wet season to the cooler dry season. Typically, this period offers a pleasant balance of sunshine and occasional rainfall, with temperatures averaging between 25-28C (77-82F). Humidity levels begin to decrease, making the climate more comfortable. Ocean temperatures remain warm, ideal for swimming and water activities.
This transitional month presents an advantageous time for travel, as it often avoids the peak season crowds and higher prices of the drier months while still providing ample sunshine and warm waters. Historically, May has been a time of preparation for traditional Polynesian celebrations and festivals marking the change of seasons, some of which may still be observed in certain islands. This makes it a potentially interesting period to experience local culture.
