The Lowdown

Alright, Rusty here with a look at the next couple of weeks for Koeel Bay. It’s a reef set-up, intermediate territory, and fairly consistent when the swell lines up.

Right now, we’re in a bit of a flat spell. The first few days are pretty quiet, with Sunday the 30th offering a fading 5ft swell at 12 seconds from the SW. That’s carrying moderate wave energy (741), but with a cross-off wind and only a 2 out of 10 quality score, it’s not really singing. The water’s sitting at 59°, which is about normal for this time of year.

Monday the 31st stays small at 4ft from the SW, still with weak energy (382) and cross-off breeze. It’s surfable, but nothing to write home about.

Things start to build Tuesday the 1st of September as the swell pushes up to 6ft, then 7ft in the afternoon, with a long 13-14 second period. The combined energy jumps into the strong zone (1310 then 1697). Problem is, the wind swings cross-on and cross-shore, putting a bit of a chop on it. The scores are low, so this one’s for the die-hards only.

Wednesday the 2nd of September is where it gets interesting. Morning brings a solid 6ft SW groundswell at 14 seconds, with light SSE winds straight off the land. That’s clean, lined-up reef waves with strong energy (1338). This is the stand-out session for the first week – a 4 out of 10 quality call. The afternoon drops off a bit as the wind picks up.

Thursday the 3rd has a weird one – early light rain with a tiny 3ft SW swell, then the wind cranks to 35 km/h from the SE for the afternoon on a short-period 7ft S swell (8 seconds). That’s not a paddling-friendly setup; more like kite-surfing territory if you’re into that.

Friday the 4th and Saturday the 5th are blown out by strong offshore winds – 35-40 km/h. The swell is mixed, small, and hard to paddle into. Not our day.

We get a little lull from Sunday the 6th through to Friday the 11th of September. Most days have weak to moderate energy (107 to 668), with swells under 4ft. The glassy conditions on Sunday the 6th afternoon and again on Wednesday the 9th morning are pretty, but there’s just no push to the waves. The 15-second period on the 11th is promising, but the wind is cranking at 35 km/h, messing it up.

Now, keep an eye on Saturday the 12th of September. That morning shows 5ft SW swell at 13 seconds, with clean offshore winds from the east (25 km/h) and moderate energy (860). The afternoon cleans up even more – 5ft SW swell, moderate offshore breeze, and the quality score jumps to a 3 out of 10. This is the pick of the second week – clean, solid waves for the experienced crew.

Sunday the 13th is a write-off with onshore wind, but Monday the 14th of September closes the forecast with a bang. Big 6ft SW groundswell building to 7ft by afternoon, a very long 15-16 second period, and combined energy hitting a massive 2295. The wind is light and cross-off, keeping it clean. That’s expert-only territory – size, power, and perfect shape. A genuine standout if you’re ready for it. Just watch the tide.

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.
