Otherwise known as the Austral or Southern Summer; the humid and rainy season commences in November and concludes in the March. Throughout these six months the region characterises unclear, cloudy skies, brisk but heavy showers and very warm temperatures ranging anywhere from 25°C to 35°C. The rainy season brings a constant mugginess that can cause slight discomfort is you’re holidaying throughout this period. Humidity levels are extremely high and are also much heavier than months outside of this season. During this time of the year, rainfall is evidently much more frequent than that in the dry season and tropical storms will commonly take place. Wind speeds can regularly exceed normal rates and can surpass to over 220 km/h causing major damage to both lives and property. Even though this is a rather rare event, tropical depressions can take place resulting in cyclones.
Tahiti is rarely hit by destructive cyclones and its last occurrence was at the beginning of the 90’s after being wrecked by six uninterrupted cyclones in less than a year from 1982 to 1983; being the worst incident since 1906. The occurrence and regularity of these cyclonic events is a result from the well-known weather phenomenon of El Nino.

Being from California you might remember 1982-83 as being the last great El Nino event which created all the landslides and flooding in California, apparently had quite an impact upon Tahiti (6 cyclones in one year and none in the next 30).
