Issued Thursday, October 26, 2017

The southern hemisphere’s relative absence of landmass compared to the northern half of the globe has major implications when it comes to swell formation and propagation around Australia. The virtually uninterrupted expanse of the Southern Ocean encompasses over 20 million square kilometres of open ocean, allowing for polar storm-genesis in perpetuity; a never-ending succession of fronts and lows marching west to east, regularly extending vigorous cold fronts across the southern Australian states as they extend north into the mid-latitudes. The point is, Australia gets solid surf year-round – admittedly nowhere near as consistent in the warmer months – but it means a major swell-event is a possibility at anytime of year.
