Climate New Caledonia Island
New Caledonia has a tropical climate, but due to its distance to the equator it is no longer quite as hot and humid. A mountain range running along the main island divides it into a humid north and east and a dry west and south. The humid air of the southeast trade wind rains predominantly on the east side of the mountains. The annual precipitation in the east is between 2500 and 4000 mm per year. In the rain shadow southwest of the mountain range they amount to less than 1500 mm. Furthermore, one can distinguish between two seasons. From December to March it is warm, humid and windy. Rain showers are frequent and very intense. The maximum values are usually between 27 and 29 degrees. The danger of cyclones is highest during this time. From April to November the temperatures are lower with average values between 22 and 27 degrees. Rain falls less frequently from August to November and in smaller quantities than in summer.
For trips to New Caledonia, the months of September to November are recommended. Then temperature and humidity are more pleasant and rain showers are less frequent.
