This is the peak Winter period when large intense Cold front/cyclones can centre between 30° and 40° north within the persistent westerlies. The Anti-cyclone centres near the edge of the tropics and the occasional Warm cyclone can persist within the weak easterlies over warm poleward currents. North and west facing coastlines receive large swell from Cold front/cyclone activity while north and east facing coastlines can receive refracted swell and/or swell from the Cold cyclones north east fetch. North, south and east facing coastlines occasionally receive large swell from Warm cyclones while south facing coastlines can occasionally receive long range swell from Hot cyclone activity in the southern tropics.

The peak dry season continues along with light east to north easterlies. North and east facing coastlines occasionally receive swell from Cold/Warm cyclone activity in northern middle latitudes, while north and west facing coastlines receive swell from Cold front/cyclone activity in the north. South and east facing coastlines can receive swell from Hot cyclone activity in the southern tropics.

The peak wet season continues along with Monsoons, troughs/Hot cyclones which occur within the persistent east to south easterlies. North, south and east facing coastlines can receive large swell from this activity while south and west facing coastlines occasionally receive swell from Cold front/cyclone activity in the south. North facing coastlines occasionally receive long range swell from Cold/Warm cyclone activity in the northern middle latitudes.

This is the peak Summer period when trough/Hot cyclones continue to swing poleward from the southern tropics while variable easterly winds prevail. The Anti-cyclone centres near 50° south while Cold front/cyclones begin their slow equatorward migration in the westerlies at about 60° south. North, south and east facing coastlines receive swell from trough/Hot cyclone activity while south and west facing coastlines occasionally receive swell from Cold front/cyclone activity in the south. North facing coastlines occasionally receive long range swell from Cold/Warm cyclone activity in northern middle latitudes.
