September in Tahiti marks the transition from the dry season to the wet season. Visitors can expect daytime temperatures averaging in the low 80sF (high 20sC) with comfortable humidity. Rainfall becomes more frequent, often in short, heavy bursts, typically in the afternoons or evenings, leaving much of the day sunny. Ocean temperatures remain warm, ideal for swimming, snorkeling, and other water activities.
This period offers a unique balance. The increased rainfall revitalizes the lush landscapes, creating vibrant scenery. While the chance of showers increases, it typically doesn’t disrupt outdoor activities entirely, and the slightly lower prices compared to the peak dry season make it an attractive time to visit. Historically, September has been a period of transition for Polynesian cultures, signifying the change of seasons and the beginning of preparations for upcoming festivals and harvests.
