Some people comment that New Caledonia is the “land of eternal spring.” However, there is distinct variety in the weather patterns throughout the year. Since it is farther south than most of the other islands in the South Pacific, New Caledonia generally has a very sunny, moderate climate. Often, its weather is compared to that of the south of France. The trade winds from the southeast also provide nice cooling breezes. Regardless, there are three seasons. The warm season last from September to March and boast temperatures between 77°F and 80°F; visitors should note that even during this time, there can be short, unpredictable, tropical rains. Then comes the cool season, from April to August, has temperatures averaging between 68°F and 73°F. Again, compared to other climates, this is still good and pleasant weather and meanwhile the water temperature stays warm enough for swimming. After the cool season, from December to March is hurricane season; during this time, the weather becomes warmer but it is also much rainier. Torrential showers can not be predicted and are sporadic, but they do not tend to last the whole day. Regardless, during this time, there can be heavy, tropical downpours and at times, a lot of flooding, which can make travel and relaxing on the beach rather difficult.

Due to these weather trends, most tourists opt to come when the weather is ideal in the summer time.
