During December, French Polynesia experiences the start of its wet season. This period is characterized by higher temperatures, increased humidity, and a greater chance of rainfall. Average temperatures typically range from the mid-70s to the mid-80s Fahrenheit (mid-20s to high-20s Celsius). While rain showers are more frequent, they are often short-lived and interspersed with periods of sunshine. Sea conditions can become more unpredictable with occasional strong winds and higher waves.
Understanding the climatic conditions prevalent in this South Pacific archipelago during December is crucial for travelers. This awareness allows for appropriate packing and activity planning. While the increased chance of rain might deter some, the warm temperatures and lush landscapes create a unique tropical experience. Historically, December marks the transition between the dry and wet seasons in this region, influenced by the South Pacific Convergence Zone.
