The Lowdown
Alright, mate, Rusty here. Let's have a look at what's on the table for Koeel Bay over the next couple of weeks.
We start off with a bit of a slow one. Thursday the 27th kicks off with some small 4ft swell from the south, but the wind is cross-on and it's a mess. The combined energy is weak (555), and the conditions are pretty marginal. Not worth paddling out for.
Friday the 28th is where it gets interesting. The morning brings a drop in swell to 3ft, still from the south, but the wind goes glassy. The energy is light (322), but the surface will be like a mirror. That's a proper window for a longboard or a funboard. The afternoon sees a shift to a cleaner cross-off breeze from the south, with a bit of a longer period swell (14 seconds) and a 2ft south-west swell. The energy is light (355), but the conditions are clean. A solid day for a mellow session.
Saturday the 29th is a bit of a write-off. The wind goes cross for the morning and fresh cross for the afternoon, putting a chop on the surface. The swell is small, and the energy is weak (373 and 303). Not worth getting excited about.
Sunday the 30th is the standout of the first week. The morning brings a building 5ft swell from the south-west, with a 13-second period and a clean cross-off breeze from the south. The combined energy is moderate (732), and the conditions are clean. This is the best wave of the week. The afternoon holds up as well, with the same swell and clean conditions. This is your session.
Monday the 31st is a step back. The wind swings cross-on again, and the swell drops to 4ft. The energy is weak (352). The afternoon has a rare onshore wind from the west, which is weird. Not great.
Tuesday the 1st of September sees a jump in swell to 6ft in the morning and 7ft in the afternoon, but the wind is howling from the north-northwest at 19 mph. The energy is moderate at 956 for the morning, but the surface is lumpy and cross-onshore. That's a no-go for a clean surf.
Wednesday the 2nd is promising on paper. The swell bumps up to 8ft from the south-west with a 14-second period, and the wind is a clean cross-off from the south-southeast. The energy is strong (2390). The conditions are clean, but that's a big wave for Koeel Bay. It's a reef break, so it could handle it, but this is expert territory. Not for the faint of heart.
Thursday the 3rd and Friday the 4th are blown out. The swell is 12ft from the south-southeast, but the wind is a near gale at 34-37 mph. The energy is very strong (over 2000), but it's unsurfable. The water temperature is about average for this time of year, so no surprises there.
Saturday the 5th is a tease. The swell is 12ft from the south-southeast, the wind is glassy in the morning and clean cross-off in the afternoon. The energy is very strong (2019 and 2245). The conditions are perfect, but that swell is just too big for this break. Even for the best, it's a no-go.
Sunday the 6th and into the next week, the surf drops off. The wind is cross-on and the swell fades to 8ft and then 5ft. The energy drops to moderate (1325 and 946). The conditions are lumpy and choppy. Koeel Bay goes quiet again.
From the 8th of September onwards, it's a long stretch of poor surf. The swell is small, the wind is onshore or cross-on, and the energy is weak (below 200). The best you can hope for is a bit of a clean-up on the 11th, with a 3ft south-southwest swell and a cross-off breeze, but the energy is still weak (163). That's a long gap with no real quality.
In summary, if you're looking for a wave, the Sunday the 30th is your best bet. That's a clean, moderate swell that's accessible for intermediates. The Wednesday the 2nd is a big wave for the experts.
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.
