Information about the Groenvlei Surf forecast

The above surf forecast table for Groenvlei provides essential information for determining whether the surfing conditions will be good over the next 12 days. A general guide to surfing at Groenvlei can be found by selecting the local surf guide option on the grey menu. Our Groenvlei surf forecast is unique since it includes wave energy (power) that defines the real feel of the surf rather than just the height or the period. If you surf the same spot (Groenvlei) regularly then make a mental note of the wave energy from the surf forecast table each time you go. Very soon you may start to choose your surf days based on the wave energy alone combined with our forecast of favourable offshore wind conditions. Our star ratings will help here and of course you will also find the usual wave height and period predictions on our surf forecasts as well as a full break down of the swell components under our advanced users option (to reveal that, click the little Einstein character under the tide times).

Further information to help with frequently asked questions about our surf forecast for Groenvlei may be found under the help tab on the top menu and also by moving your mouse over the question marks on the surf forecast table itself. Please always bear in mind that the forecast is for near-shore open water and local factors at each surf break influence the actual breaking wave height, such as the beach / reef profile, water depths offshore and shelter.

Groenvlei is 26 km (16 miles) from the city of Knysna. If you plan a holiday in Garden Route, look for hotels and other accommodation in Knysna. Knysna has rooms for a wide range of budgets as well as car hire and transport links.
