The wet season and the tropical cyclone season for Fiji and the Southwest Pacific region ended on 30 April ,2015.

From May 1 2015 to October 31 2015, is officially the dry season when only about 25 per cent of the annual total rainfall contribution comes from these 6 months with November to April contributing about 75 per cent of the total annual rainfall, in most locations in Fiji, in normal average circumstances.

The axis of the eastward migrating anticyclones (area of High pressure) in an East to West manner zonally, moves much closer to Fiji, bringing in much cooler and dry air from the higher latitudes with much more pleasant conditions especially during the months of June, July and August.

Rainfall is much more irregular with the main rainfall of substantial amounts often about 4-6 weeks apart from large scale upper atmospheric troughs of low pressure moving eastwards over us, giving substantial rains often as much as 60-100 millimetres at times, within a 24-hour period.

The South-easterly trade winds will also become very pronounced, as a result of the axis of the high pressure systems moving much closer south of Fiji. Thus seas become rougher with much more pronounced Southerly sea swells on the southern coasts of the islands.

No tropical cyclones are expected from now till the end of October 31, 2015 and Fiji has been blessed to have been saved from TC Pam, which is something that Fijians should never forget.
