The Lowdown
Alright mates, Rusty here. Let’s break down the next couple of weeks for Koeel Bay.
We’ve got a solid run of southwest groundswell on the way, but the first few days are a bit messy with onshore winds spoiling the party. The real standout is Friday the 24th of July, with flat, glassy conditions and a solid 8ft SSW swell rolling in. The combined energy is pumping at 2467 (moderate to strong), and with a 15-second period, this is proper groundswell. That’s one for the experienced crew, because at that size, it’s not for the beginners. The water is sitting at 60°, which is about normal for this time of year, nothing unusual there.
The other big highlight is the last day of the month, Friday the 31st of July. Another morning of glassy conditions, with 8ft SSW swell at a very long 17-second period. Combined energy is huge at 3194 (strong). That’s a day for the reef and looking for a clean take-off. Expect some serious lines, but the long period might make it a bit walled-up at the beach, so stick to the peak.
Now, let’s walk through the week. Tuesday the 21st kicks off with a 6ft SSW swell, cross-off wind, and clean conditions. A decent start, but the energy is high at 1331 (moderate). Wednesday the 22nd and Thursday the 23rd are a write-off with onshore and cross-onshore winds in the 9-16 mph range, making for choppy, poor surf. The swell drops to around 4-5ft, nothing worth paddling out for.
Once we hit the morning of Friday the 24th, it’s game on. Glassy, 8ft, and clean. That’s your best bet for the first week. Saturday the 25th eases off a bit, with 6ft and glassy conditions in the morning, still very good. Sunday the 26th is smaller and a bit cross-shore, marginal.
The following week holds some promise. Monday the 27th is a bit smaller, with a moderate offshore breeze from the ESE at 16 mph, keeping things clean but the swell is only around 3-4ft. Tuesday the 28th kicks back into gear with a solid 7ft SSW swell, 16-second period, and combined energy of 3316 (strong). The catch is moderate rain, but the wind is light and cross-off, so it’ll be clean. That’s a big day for the experienced surfers.
Wednesday the 29th and Thursday the 30th are smaller, with cleaner conditions but not as punchy. Then bam, Friday the 31st of July delivers again with that 8ft, 17-second glassy session. Crowds are "sometimes" a factor at Koeel Bay, so you might have some company on those peak days.
The first week of August sees the swell drop right off. Saturday the 1st has some light rain and onshore wind, marginal. Sunday the 2nd is small, with offshore winds but only 3ft. By Monday the 3rd and Tuesday the 4th, it’s tiny, with 1-2ft. Wednesday the 5th picks up a bit to 6ft, but it’s onshore again, so not great.
Overall, mark your calendar for Friday the 24th and Friday the 31st of July. Those are the standouts. The rest is a mix of smaller, wind-affected days, so don’t sleep on the glassy mornings.
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.
