The Lowdown

G’day, Rusty here, looking at what’s coming up for Koeel Bay. We’ve got a bit of a slow start, but this reef setup has some real potential if you time it right, especially for the intermediate crew. The water’s sitting at 59°F which is pretty much what you’d expect for this time of year—nothing unusual there.

The first few days are pretty ordinary, to be honest. Saturday morning, the 1st of August, we’ve got a tiny 3ft SW swell with a 14-second period, and the energy is weak (256). The wind is glassy though, so if you’re desperate for a paddle, you’ll get some clean little waves. That glassy condition hangs around through Saturday afternoon, but the swell’s still small. Sunday and Monday stay small too, with the swell barely cracking 3ft, and the wind gets a bit messy on Sunday morning with a cross-onshore breeze.

Now, Monday the 3rd of August is where things start to look up. Monday morning is glassy with a 3ft SW swell, 13-second period, and the energy is picking up a bit (337). The wind is dead calm, so it’ll be clean. Monday afternoon gets even better—a 3ft SW swell, cross-off wind, and the energy jumps to 392. This is a solid window for a session, with clean, surfable waves.

Tuesday the 4th is a bit of a letdown, with the swell dropping back to 3ft and the energy fading (183). The wind is onshore in the morning, but Tuesday afternoon goes glassy again, so you could still get a few, but it’s nothing to write home about.

Wednesday the 5th is a write-off. The wind cranks up to 15-19 mph from the NNW and NW, a cross-onshore mess, and the swell jumps to 5-6ft, but with that wind, it’s choppy and lumpy. Don’t bother.

Now, Thursday the 6th of August is the first real standout. The swell builds to 10ft from the SW, with a 13-second period, and the energy is strong (2,561). Thursday morning has a light cross-off wind, so it’s clean, but that 10ft is getting big—this is for experienced surfers only. Thursday afternoon is even better: the swell drops slightly to 8ft, but the wind goes offshore from the ESE at 12 mph, and the energy is still huge (2,522). The waves will be clean, powerful, and lined up. This is a proper session for the skilled crew.

Friday the 7th is a step down, with the swell dropping to 7ft in the morning, but the wind is onshore, so it’s messy. Friday afternoon is worse, with onshore wind and a 6ft swell. Skip it.

Saturday the 8th of August is another big day, but it’s tricky. The swell is 8ft in the morning with a strong cross-onshore wind, so it’s choppy. Saturday afternoon, though, the swell jumps to 10ft from the WSW, the wind goes cross-off, and the energy is off the charts (7,225). That’s a lot of power, and it’s clean, but again, it’s for experts only.

Sunday the 9th of August the swell is too big for Koeel Bay—13ft to 15ft from the SSW. The wind is offshore and clean, but the size is just too much for this reef. Same story on Monday the 10th, with 18ft swell and offshore wind. Tuesday the 11th keeps the swell big at 10-13ft, but it’s offshore and clean. If you’re a top-tier surfer, you might charge it, but for most of us, it’s a no-go.

Wednesday the 12th of August brings a real change. The swell drops to 3ft, but it’s a long-period 19-second groundswell from the SW. The energy is still strong (1,562), and the wind is offshore. That long period will produce some beautiful, clean lines—perfect for a reef like Koeel Bay. Thursday the 13th keeps it going with a 4ft SW swell, 15-second period, and gentle offshore wind, making for a classy session.

The final stretch, from the 14th to the 16th of August, fades off. Friday the 14th has 3ft SW swell with offshore wind, clean but small. Saturday the 15th is glassy with a 4ft SW swell, so it’s a nice little weekend session. Sunday the 16th gets a bit bigger at 8-8ft from the SW, with cross-off wind, but it’s getting messy again.

Overall, the standout is Thursday the 6th of August afternoon, with that 8ft SSE swell, offshore wind, and huge energy. For a more mellow, clean session, Monday the 3rd afternoon and Wednesday the 12th morning are your best bets. Keep an eye on that long-period swell on the 12th—it’ll be a gem.

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.
