Fiji enjoys an ideal South Sea tropical climate without great extremes of heat and cold. Summers can get hot but seldom reaches above 35°C (96°F).
The predominant winds over Fiji are the south southeast trade winds. On the coast of both main islands, Viti Levu and Vanua Levu, day time sea breezes blow with great regularity. Generally, the winds are light or moderate. Strong winds are uncommon and are most likely to occur through channels and around headlands during the period between June and November.
Temperatures at the lower levels around Fiji are fairly uniform. Due to the surrounding ocean, the changes in day-to-day and season-to-season temperatures are fairly small. The average temperatures change by only 2°C to 4°C between the coldest months (July and August) and the warmest months (January and February).
Around the coast, the average night-time temperatures can go as low as 18°C to 20°C and the average day-time temperatures can go as high as 30°C to 32°C. South-eastern coastal areas and the high interiors often experience persistent cloudy and humid conditions.
Rainfall is highly variable and mostly influenced by the islands topography along with the south-east trade winds. These winds are saturated with moisture.
The Mountains of Viti Levu and Vanua Levu create wet climatic zones on their windward or eastern sides. This helps in creating pristine, lush and dense tropical rainforests bringing with it, stunning waterfalls and rivers. The leeward or western side has dry climatic zones making way for rolling grass covered hills, pine forests, thinner jungles, mountains and many of the country’s beaches and resorts. The topography of the main islands means that Fiji has distinct dry and wet zones.
The traditional wet season lasts from November to April and the dry season from May to October. Much of Fiji’s rain falls in heavy, but brief, tropical showers.
Fiji lies in an area occasionally traversed by tropical cyclones. They are mostly confined to the period between November to April, with the greatest frequency historically being in the months of December and January.
