Have you ever seen the old movie Endless Summer? Most of the spots they filmed were filmed in winter! Surfers have always been meteorologists of a sort. Especially in the old days before the internet. Winter cold fronts are generally what create the swells that people surf. The northern and southern hemisphere winter fronts crossing the globe over the Pacific and Atlantic generate the vast majority of swell. Once and a while a tropical low pressure like a hurricane will whip up a swell. Often the same storm crossing Russia will snow in Northern Japan then send swell to Hawaii then California and maybe even snow in Texas as it moves east - or at least bring rain. Hmmm i didn't check if Texas gets any snow? Haha.

The pro surfing tour is currently in South Africa at Jeffery's Bay. Winter in Africa.

Onshore wind is always bad for surfing conditions. it's not always onshore though. So you surf around the wind.

Howdy again sir rossfletcher! That old movie sounds very familiar but I don't think I ever saw it. But that's funny that it was filmed in the winter. lol.Also very interesting about the weather patterns that surfers watch, I didn't realize it would be to that extent but it makes perfect sense! Great information.

On the global scale the jet stream and storm movement is pretty simple to see. Local forecasting is... well, everyone knows you never quite know exactly what yer gonna get right? Haha!

Howdy this fine Sunday sir rossfletcher! yes sir, so true on both counts! The local forecasts here in Texas are usually ridiculously undependable.
