Climatology
This page presents Fiji's climate context for the current climatology, 1991-2020, derived from observed, historical data. Information should be used to build a strong understanding of current climate conditions in order to appreciate future climate scenarios and projected change. You can visualize data for the current climatology through spatial variation, the seasonal cycle, or as a time series. Analysis is available for both annual and seasonal data. Data presentation defaults to national-scale aggregation, however sub-national data aggregations can be accessed by clicking within a country, on a sub-national unit. Other historical climatologies can be selected from the Time Period dropdown list.
Observed, historical data is produced by the Climatic Research Unit (CRU) of University of East Anglia. Data is presented at a 0.5º x 0.5º (50km x 50km) resolution.
Temperatures in Fiji remain relatively constant throughout the year, averaging around 23°C -25°C in the dry season (May-October) and 26°C -27°C in the wet season (November-April). Greater seasonal variation is seen in the precipitation regime, with an average of around 250-400 mm of rainfall per month in the wet season and 80-150 mm per month in the dry. Periods of drought are known to occur during El Niño periods. Annual precipitation shows some spatial variation, Fiji’s most populous island, Viti Levu, sees much stronger precipitation on its east side (3,000-5,000 mm) compared to its west (2,000-2,000 mm). Tropical cyclones are a major feature of climate in the Fijian region and are another variable influenced both in terms of intensity and location by El Niño Southern Oscillation (ENSO).
