During August 2023, near normal or below normal rainfall is likely for the Fiji Group.
For August to October period, near normal or below normal rainfall is likely for the Fiji Group. There is little guidance provided for Rotuma, as there is almost equal chances of below normal, normal and above normal rainfall.
During November 2023 to January 2024, near normal or below normal rainfall is likely for the Fiji Group. There is little guidance provided for Rotuma, as there is almost equal chances of below normal, normal and above normal rainfall. However, a development of a tropical disturbance or depression, during this period, can result in normal or above normal rainfall.
For the August period, maximum temperature is likely to be below normal across the Western and Central Divisions, near normal for Northern and Eastern Divisions, while above normal temperature is likely at Rotuma. Minimum temperature is likely to be near normal across the Western, Central and Eastern Divisions, while above normal temperatures are likely across the Northern Division and also at Rotuma.
Maximum temperature is likely to be near normal over the Fiji Group during August to October 2023, while above normal temperature is likely at Rotuma. Minimum temperature is likely to be near normal across Western, Central and Eastern Divisions, while above normal temperatures are likely across the Northern Division and at Rotuma.
El-Niño Southern Oscillation (ENSO) is currently in a weak El Niño state.

· A weak El-Niño event continues to persist within the tropical Pacific Ocean.
· Sea surface temperatures are further likely to warm and remain above El Niño thresholds until at least the end of the year.
· The current El Niño is expected to gradually strengthen through to the December 2023 to February 2024 period.
· Fiji usually experiences below normal rainfall during an El Niño event.
· The model predictions for later part of the year at this time have lower accuracy. Thus, it is difficult to ascertain with accuracy the ENSO state for later half of the year;
· Fiji Met Service will continue to monitor the ENSO conditions closely and provide updates accordingly.
