Fiji has a tropical maritime climate, hot and humid but tempered by trade winds, particularly in the winter months. Rainfall is frequent especially between November and April and generally we see higher rainfall on the eastern and south eastern parts of Fiji (for example, Suva) that are more exposed to the trade winds.

The mountains of the main islands of Viti Levu and Vanua Levu create wet climatic zones on the windward sides and dry climatic zones on their leeward sides. The prevailing winds are from the south-east leaving the north-western and western areas relatively dry. This includes Nadi, Denarau, the Mamanucas and Yasawas.

Most rain falls in the form of brief but intense rainfall, which often occur in the afternoon. The average annual rainfall in the driest areas reaches 2,000 mm, while in wettest regions varies from a minimum of 3,000 mm in coastal areas, up to a maximum of 6,000 mm in the interior. The wettest month is usually March, while the driest is July.

Tropical cyclones are generally possible in the months between November and April with more frequency in the months of December, January and February.

The temperatures of Fiji are very uniform with little seasonal variation, the average temperature varies by only 2°C/6°C between the coolest months (July, August) and the warmest (January, February).

In the Denarau, the highest average annual temperatures vary between 34°C in February and 28°C in July, while the annual average minimum temperatures vary between 23°C in February and 18°C in July and August.

The sea water temperature is maintained throughout the year between 25°C and 30°C.
