The climate is tropical, with hot and humid period from November to March with temperatures between 27°C and 30°C, and a cooler, dry period from June to August with temperatures between 20°C and 23°C, linked by two short transition periods. The tropical climate is strongly moderated by the oceanic influence and the trade winds that attenuates humidity, which can be close to 80%. The average annual temperature is 23°C, with historical extremes of 2.3°C and 39.1°C.
The rainfall records show that precipitations differ greatly within the island. The 3000 mm of rainfall recorded in Galarino are three times the average of the west coast. There are also dry periods, because of the effects of El Niño. Between December and April, tropical depressions and cyclones can cause winds to exceed a speed of 100 km/h with gusts of 250 km/h and very abundant rainfall. The last cyclone affecting New Caledonia was Cyclone Vania (2011), in January 2011
