The Lowdown
Alright folks, Rusty here. Let’s have a look at what’s on the cards for Koeel Bay over the next couple of weeks.
First up, we’ve got a bit of a slow start. Tuesday the 4th is pretty flat and ordinary, with some tiny 3ft swell from the SW and clean glassy conditions, but there’s just no energy behind it. Nothing to get excited about, so I’d say give it a miss.
Now, Wednesday the 5th sees a big jump in swell – up to 5ft to 5ft from the SW, with a really long period of 15-16 seconds. That’s proper groundswell. But the wind is howling from the NNW, cross-on, at 15-18 mph, and it’s going to be choppy and messy. The combined energy is strong (over 1000), but the quality is poor. Not worth paddling out, unless you’re on a kite – this setup looks more interesting for kite surfing than paddle surfing.
Thursday the 6th is where it starts to get interesting. The swell drops back to 6ft to 6ft from the SW, but the wind goes offshore from the SE, light to moderate, and the conditions are clean. The combined energy is still strong at 1237, and the period is a solid 12-13 seconds. This is very good surf, and the offshore wind will make it clean. This is a solid option for intermediate surfers.
Friday the 7th is the real standout. We’ve got a 7ft to 8ft swell from the SSW, with a very long period of 14-16 seconds, and offshore wind from the ESE at 9 mph. The combined energy is massive – 2027 in the morning, 2963 in the afternoon. This is excellent surf for experienced surfers, with clean, powerful waves. This is the best on offer in the whole outlook. The water temperature is 60°, which is about average for the time of year.
Saturday the 8th is a step down. The swell drops to 6ft to 6ft from the SSW, but the wind goes cross-on and then onshore, making conditions marginal. The combined energy is still decent (975-1253), but the wind is not your friend. I’d skip it.
Sunday the 9th is a no-go. The wind is screaming from the SSE at 25 mph, and the swell jumps to 12ft in the afternoon. That’s too big for this break, and the wind is cross-off but strong. Combined energy hits 4241, but it’s just too messy and oversized. Leave it.
Monday the 10th sees the swell at 8ft to 10ft from the S and SSE, with strong offshore wind from the ESE at 15-18 mph. The combined energy is high (1989-2439), but the period is short (10-11 seconds), and the conditions are described as marginal. It’s a powerful but tricky day – only for experts who know the spot.
Tuesday the 11th is a nice change. The swell drops to 7ft to 8ft from the SE, with a glassy morning and light wind. The combined energy is still strong (1660-1697), and the period is 10 seconds. The morning glass-off means excellent surf for experienced surfers, but the afternoon gets a bit cross-shore. The morning session is the pick.
Wednesday the 12th brings a long-period groundswell from the SW at 18-19 seconds, with swell heights of 4ft to 4ft. The combined energy is moderate (1158-1189), and the wind is light or glassy. This is very good surf, and the long period will give clean, well-shaped waves. This is a good call for intermediate surfers, and the crowds are only sometimes an issue.
From Thursday the 13th onward, the swell drops off and the quality fades. There’s a decent morning on Thursday the 13th with 5ft from the SW, but it’s cross-shore, so it’s only marginal. The afternoon of the 13th is glassy with 4ft, which is good but not great. The rest of the week into the 14th, 15th, 16th, and 17th is mostly small, weak, or windy. The 17th has strong cross-on wind and messy conditions, so avoid it.
Tuesday the 18th is a late bright spot. The swell is 5ft to 5ft from the SW, with clean cross-off wind from the SSE. The combined energy is moderate (634-722), and the conditions are clean. This is a good option for a session if you’re patient. After that, Wednesday the 19th is back to cross-on wind and choppy, so it’s a bit of a letdown.
So, to sum it up: the clear standout is Friday the 7th at Koeel Bay. That’s the one to circle. The morning of Thursday the 6th and the morning of Tuesday the 11th are also solid. The long-period swell on Wednesday the 12th is a good backup. The rest of the outlook is a mix of small, windy, or messy days, with a few clean windows here and there.
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.
