Alright crew, Rusty here with the lowdown for Koeel Bay.
Right now we’ve got a slow start—Sunday the 5th is flat with tiny 2ft waves and cross-onshore winds. Not worth paddling out. But hold tight because Monday the 6th brings a shift: glassy conditions, swell bumping to 4ft out of the southwest, and the combined energy sitting at moderate (369). That’s clean, small but promising for the intermediates.
Tuesday the 7th sees the swell push 4–5ft from the SW but the wind gets a little cross, keeping things marginal. The wave energy climbs into strong territory by the afternoon (806).
Wednesday morning the 8th is a solid window: glassy, 5ft SW groundswell with a 13-second period, and combined energy at 988. That’s strong, clean, and the best bet of the first week for most of you.
But the standout is Thursday the 9th – excellent conditions for the experienced crew. We’re looking at 8ft SSW groundswell with a 14-second period, moderate offshore wind from the ESE, and the combined energy cranking up to 1846. That’s strong stuff and the size means it’s experts only. Crowds are possible here, so go early. Friday the 10th remains clean and offshore with waves holding around 6–6ft, still worth a session for the proficient.
After that, the swell drops steadily. By Sunday the 12th we’re down to 4ft with onshore wind, and by Monday the 13th it’s back to tiny 2ft and poor again. There’s a gap of a few quiet days from Tuesday the 14th to Wednesday the 15th with very small swell under 3ft.
Thursday the 16th sees a massive spike in energy – 8ft SSW, combined energy of 2785 – but the wind is onshore and messy. That setup is more kite-friendly than paddle-friendly. Friday and Saturday stay lumpy and choppy with strong cross-onshore winds.
We get a little relief on Sunday the 19th – glassy morning, 4ft south swell, moderate energy. Clean and surfable, but nothing special.
In short, Thursday the 9th is your best call – big, offshore, and powerful for the experienced. Wednesday morning the 8th is the next best for those wanting clean, strong waves at a manageable size. The rest of the window is either too small, blown out, or average.
Rusty.

Information about the Koeel Bay Surf forecast
The above surf forecast table for Koeel Bay provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Koeel Bay can be found by selecting the local surf guide option on the grey menu. Our Koeel Bay 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 (Koeel Bay) 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 Koeel Bay 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.
Koeel Bay is 18 km (11 miles) from the city of Grabouw. If you plan a holiday in Overberg, look for hotels and other accommodation in Grabouw. Grabouw has rooms for a wide range of budgets as well as car hire and transport links.
