The Lowdown
Alright folks, Rusty here. Let's have a real good look at what's on the cards for Koeel Bay.
We’ve got a solid 16-day window of surf ahead, but it’s a bit of a mixed bag, so you gotta pick your moments. The water temp is sitting at 59°, which is pretty much what you’d expect for this time of year, nothing freaky going on there.
First up, we kick off on Thursday, the 6th of August. Thursday morning is looking clean with a light offshore breeze and a 7ft swell from the SW. That’s a decent groundswell with a 13-second period, packing some serious grunt with a combined energy of 1336. It’s going to be a bit of a handful for the average punter, better suited to the experienced crew. By Thursday afternoon, the wind picks up to a moderate 12 mph cross-offshore breeze, the swell bumps up a touch to 7ft, but the energy is pumping at 1420. It’s a bit more on the marginal side, so maybe not the pick of the day.
Now, Friday the 7th of August is where my heart starts to beat a little faster. Friday morning you’re looking at glassy conditions, 3 mph from the ENE. The swell is 7ft, coming from the SSW, and the period is a solid 15 seconds. The energy reading is 1911 – that’s a proper amount of water moving. This is a standout morning for the experienced surfer. The offshore wind direction (ESE) is a good match for the break’s optimum from the S, so the lines should be clean. The afternoon sees the wind swing to a light cross-on, but the swell bumps up to 8ft and the energy jumps to 2368. It’s a bit of a trade-off.
Saturday the 8th starts to get a bit messy. A cross-on breeze and a 6ft swell. The energy is down to 1042, and the forecast is marginal. Sunday the 9th is a write-off for paddling, honestly. You’ve got a 22 mph cross-offshore wind, but the swell is 8ft in the morning, jumping to 10ft in the afternoon. The energy is massive, 4282 in the arvo. That’s a lot of juice, but it’s a strong, short-period swell (12 seconds) on a reef. For a kite surfer, that setup would be a dream. For a surfer, it’s a full-on battle.
The surf dips through the middle of the week, with Monday the 10th and Tuesday the 11th offering smaller, cleaner windows. Tuesday morning is a beauty for the more chilled surfer: 5ft, SSW, 12-second period, gentle offshore. Clean lines.
Now, hang on to your board, because the next real standout is Wednesday the 12th of August. The morning is *glassy*. A 3 mph wind from the NE, and while the swell is only 4ft, it’s a long-period groundswell of 18 seconds. The energy reading is 1380. On a reef setup like Koeel Bay, this long-period swell is going to wrap in beautifully, giving you clean, lined-up waves. The period is very long, so expect some bigger sets and longer gaps between them. This is a fantastic morning for an intermediate surfer.
Thursday the 13th is another glassy morning, with a 5ft, 17-second swell. The energy is 1306. Very similar conditions to Wednesday, just a slightly smaller ride. It’s a consistent run of excellence.
The rest of the second week fades out. Friday the 14th is small and clean, but the swell drops to 3ft. There’s a nasty run from the 15th to the 18th of August where the wind is onshore and the surf is poor. It’s a real flat spell.
But don’t write the trip off. Looking way out to the end of the run, on Friday the 21st of August, we’ve got a potential monster. The forecast is for a glassy morning with a 6ft, 14-second SSW swell. The energy is 1496. Then the afternoon looks even better: glassy again, 8ft, and a 17-second period! The energy reading is a massive 4047. This is a long-range standout, so keep an eye on it, but if it comes together, that Friday afternoon will be the best session of the entire forecast. Only for the experts, though – that’s a big, powerful swell.
Stay salty,
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.
