The Lowdown

G’day, this is Rusty. Let’s talk Koeel Bay. This reef break is the only spot worth looking at in the forecast, and it’s gonna give us a real mixed ride. The water’s sitting at 57°, which is a bit colder than normal for this time of year, so don’t forget a good suit.

We kick off this Sunday, 6th September, with some serious juice. A strong SSW groundswell with a very long period of 18 seconds pushes in at 6 ft. The combined energy is massive (1896), so there’s plenty of push. Wind is offshore from the east at 16 mph, keeping the surface clean. This is excellent for experienced surfers only—that’s a lot of power and size on a reef. The long period will make the sets a bit tricky to read, but it’ll groom the waves nicely.

Monday morning the 7th is absolute gold. The swell drops to a friendly 4 ft, but the wind goes glassy from the WNW at just 3 mph. The conditions are perfect—clean, lined up, and the energy is moderate (679). It’s one of those mornings you’ll remember. Crowds are only “sometimes” a problem, so you might get it quiet.

Tuesday the 8th drops way off to 3 ft and glassy again, but it’s too small to bother with. Wednesday and Thursday morning the 10th bring another punch: a big SSW swell jumps back up to 7 ft with a 16-second period. The energy rockets to 2119, and with a solid SE offshore at 12 mph, this is for the hard crew only. Over 8 ft of powerful swell—no place for learners.

Friday the 11th stays rideable but wind picks up, and Saturday the 12th has another classic: a fresh SSW swell at 5–6 ft with a very long 17-second period. The wind stays offshore from the ESE at 12–16 mph. Saturday afternoon looks especially clean with energy at 1622. From Thursday to Saturday next week is the best run of quality surf.

From Sunday the 13th through Tuesday the 15th, it all goes to crap. Strong cross-onshore winds from the NNW and NW wreck the surface. Swell hangs around but it’s messy and choppy. Not worth paddling out—this stretch is more interesting for kite surfing if you’ve got the gear.

Wednesday the 16th sees a recovery with moderate SE offshore wind and a consistent 5 ft SSW swell, though there’s moderate rain. Thursday the 17th is similar but with a strong breeze that’ll make paddling into sets a chore.

By the 18th and 19th, the swell direction shifts to SSE and SE, the period drops to 8–9 seconds, and the energy fades. The last few days from the 20th into the 21st are tiny—around 2–2 ft with that super long 19-second period on the last day. Not enough to get excited about.

Top picks: Monday morning the 7th for glassy perfection, and the run from Thursday the 10th through Saturday the 12th for power and quality. Everything else is either small, blown out, or for the brave only.

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.
