The Lowdown

Alright, let’s get into it. This is your regional surf outlook for the next 16 days, starting now.

We’ve got a run of good surf coming up, but there’s a few gaps and a bit of a wild stretch in the middle. The main break we’re looking at is Koeel Bay, a reef setup that’s fairly consistent and picks up a nice S-SSW swell. The water temp is about average for the time of year, nothing unusual.

The opening window is the standout. We’re looking at Wednesday the 29th of July, and it’s firing. Clean, 4ft SSW swell with a 13-second period – that’s proper groundswell, good energy (804 combined energy). Wind is light and cross-off in the morning, then it goes glassy in the afternoon. That’s the best on offer, no question. It’s a strong intermediate-level wave, and with the clean conditions, you’ll be smiling.

Thursday the 30th is still very good, a touch smaller at 3ft, but glassy in the morning and offshore in the afternoon. The energy drops a bit (475 and 357), but it’s clean and fun.

Friday the 31st starts a bit smaller, but the afternoon picks up a 3ft SE swell with a shorter 9-second period. Still glassy, still surfable, but not as punchy.

Saturday the 1st of August is small, 2ft, and glassy. It’s a beginner-friendly day, but the energy is low (227).

Sunday the 2nd is a write-off. Onshore and cross-on winds, messy conditions. Skip it.

Monday the 3rd bounces back in the morning with glassy conditions and 3ft swell, but it’s a bit inconsistent. The afternoon gets a cross-shore wind, which messes with the shape.

Tuesday the 4th is a solid return to form. Both sessions are glassy, with 3ft to 4ft SSW swell and good energy (271 and 379). Clean and fun.

Now, here’s the wild part. From Wednesday the 5th of August through to the 11th, the swell picks up big time, but the wind turns nasty. It’s going to be a stretch of onshore and cross-on winds, often strong. The swell is 7ft to 10ft, with energy ranging from 1472 all the way up to 4167 – that’s strong to very strong. But the wind is going to wreck it. This is really only for the experts, and even then, it’s going to be messy and lumpy. For a couple of days in there, it looks more interesting for kite surfing than paddle surfing, especially with the cross-on wind.

Sunday the 9th of August afternoon gives a glimmer, with a clean 6ft SSW swell and cross-off wind. That’s a decent option if you’re desperate.

Monday the 10th and Tuesday the 11th are still big, but the wind is mostly cross-on or onshore. Not your best bet.

Wednesday the 12th of August is a nice reset. Glassy in the morning, 4ft S swell, and the afternoon is clean with a 3ft SW swell. Back to fun, clean waves.

Thursday the 13th of August has a more promising 6ft SW swell, but there’s a light cross-on wind in the morning. Could be workable if the wind behaves.

So, the best bet is Wednesday the 29th of July, no contest. The second best is the Thursday and Tuesday the 4th of August stretch. After that, it’s a waiting game for the wind to drop.

Remember, the long-range standouts are promising but a bit less certain. Keep an eye on the forecast.

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.
