Average wave heights of 8m were recorded in East London around 17:00, while the highest recorded wave was 13.68m, South African Weather Service forecaster Venetia Thakula told News24 on Friday."
My surfing mates were calling it days before the SA weather service, you can see it coming these days..Best to go drink beer and watch the surfing the last two days ;)
