The Austral or Southern Summer, more often called the Rainy Season, generally lasts
from October/November to February/March and is caracterized by cloudy skies, brief heavy rains
and warm temperatures (between 24 and 31 degrees Celsius in Tahiti, and between 21 and 26 degrees in Rapa) with East to North-East alizés.
During the Rainy Season, tropical depressions can occur mostly with a South East course.
If they become tropical "cyclones" or hurricanes (rare occurrence since the last ones at the beginning of the 1980s),
winds can reach a speed of 220 km/hr and create great damages.
The water temperature is mostly constant ranging between a pleasant 26 and 29 degrees Celsius.
-The Austral or Southern Winter, more often called the Dry Season since rain is rare, usually lasts from April/May to September, and temperatures are refreshed by the South-East alizés and particularly the "mara'amu" (temperatures between 20 and 28 degrees Celsius in Tahiti, between 15 and 20 degrees in Rapa).
Finally, there is plenty of sunshine in French Polynesia ( 2500 to 2900 hours per year), especially in the atolls with a yearly average of 8 hours per day! .
