Climate zone: tropics
With a yearly average of 27 °C the climate in New Caledonia ist warm, but has only a few really tropical and sticky months. It is warm to hot all year round and invites to bathe at average water temperatures of 25 degrees. Dued to the lesser rain the best time for traveling is from August to November. The most rain days occur from from January to March.

Temperature records of the last 67 years
The hottest temperature measured from 1952 to December 2019 was reported by the Koumac weather station. In February 2004 the record temperature of 35.6 °C was reported here. The hottest summer from July to September was recorded in 1998 with an average temperature of 22.3 °C. This average temperature will normally be measured every 4 to 6 hours, thus also including the nights. Normally, this value is 20.5 degrees Celsius. The average maximum daily temperature at that time was 26.6 °C.
The coldest day in these 67 years was reported by the weather station Koumac. Here the temperature dropped to 12.1 °C in August 2003. Koumac lies at an altitude of 19 meters above sea level. The coldest winter (January to March) was in 1953 with an average temperature of 24.6 °C. In New Caledonia, it is usual to have about 1.5 degrees more at 26.1 °C for this three-month period.
Long-term development of temperatures from 1990 - 2016
In contrast to single record values, a long-term development cannot simply be brought about by all weather stations in the country. Both the number and the locations are constantly changing. A simply calculated average value would give a falsified result. If several measuring stations in particularly cold mountain or coastal regions are added in one year, the average would already decrease as a result of this alone. If a station fails during the summer or winter months, it does not provide any values and falsifies the average again. The subsequent long-term development was therefore reduced to only 2 measuring points in order to have actually comparable data over as long a period as possible.
In the years 1990 to 2016 there were only these 2 weather stations in the whole country, which reported continuous temperature values (Noumea, Koumac). From these weather reports we have created a long-term development that shows the monthly average temperatures. The hottest month in this entire period was Februar 1996 with 27.9 °C. Juli 1994 was the coldest month with an average temperature of 19.1 °C.
The average annual temperature was about 23.1 °C in the years after 1990 and about 23.4 °C in the last years before 2016. So over the past 27 years it has only increased by a minimal 0.3 °C. This trend only applies to the selected 2 weather stations in New Caledonia. A considerably more comprehensive evaluation of the global warming
