If you have an understanding of the specific swell and wind direction needed for good waves at a certain spot, www.windguru.com provides the most accurate tools to make your own surf forecasts. The site features an eight-day forecast for many of the spots around Cape Town, with daily wind and swell data broken into three-hour intervals that update automatically.
www.magicseaweed.com uses similar data and also offers an eight-day forecast. The difference is that the site creates a daily bar graph of the expected wave height at various spots and even gives it a star-rating based on the forecasted combination of wind and swell – one star for poor surf, five stars for excellent surf. This site is fairly reliable for exposed surf spots and makes it much simpler to read the data – it packages the forecast for you – but does not always take into account how much a swell has to wrap into a bay and other complex factors that influence different waves around Cape Town, which can make it inaccurate and unreliable.
www.wavescape.co.za is a local surf-forecasting site that provides a similar service to Magic Seaweed, with a seven-day forecast packaged into charts and bar graphs for most of the spots around Cape Town. But it goes much deeper and offers a detailed analysis of the forecasted surf conditions for Cape Town that is updated every few days. The forecasters have a good understanding of local conditions, so the reports – and charts – are generally much more accurate.
