The Lowdown

G’day, Rusty here. Alright, let’s have a look at what Koeel Bay is cooking up for the next couple of weeks.

We’ve got a mixed bag, but there are a couple of windows that will get the heart pumping. For the most part, the swell is solid, coming from the SSW, and the water temperature is sitting about average for this time of year, so you won’t need the thickest steamer.

Starting off on Monday the 27th of July, it’s a bit of a grind. We’ve got a chunky 7 ft SSW groundswell with a very long 17-second period, and the combined energy is pumping at 2465 (strong to very strong wave energy). Problem is, the wind is howling from the SE at 19 mph, cross-off but still fresh, and the surf quality is marginal with questionable tide conditions. It’s a day for the keen and the experienced to maybe pick their moment. Tuesday the 28th is a similar story – still a solid 6 ft SSW swell (14-second period) but that fresh 19 mph ESE offshore wind will keep the surface clean, even if the tide might still be playing tricks. Energy drops a bit to 1452 (moderate to strong).

Now, Wednesday the 29th of July is the first real standout. The swell drops to 4 ft from the SSW with a 13-second period, and the combined energy is a more manageable 728 (moderate). And here’s the magic part – the morning is glassy. No wind at all from the NE, just a slight air. That’s as clean as it gets. You’ll be looking at clean, lined-up reef breaks with long-period energy. Just keep in mind, it’s a fairly consistent spot, but crowds are sometimes a thing here, so get out early. A proper little session.

Thursday the 30th sees the swell drop a little more to 4 ft, but the wind stays light, making for clean, friendly waves. Friday the 31st, we get a shift in swell direction to a short-period ESE windswell (7 seconds) at 4 ft in the morning, combined energy only 403 (weak to moderate). It’s clean with a light offshore, but the period is short, so the shape won’t be anything special. Better on the later SW groundswell that afternoon. Saturday the 1st of August is tiny – 3 ft and glassy, a real knee-boarder special.

We then hit a patch of poor conditions from Sunday the 2nd of August through Wednesday the 5th of August. Onshore winds from the NNW and NW, all cross-on and choppy, with moderate to strong combined energy (up to 2462 on Sunday) just turning the ocean into a washing machine. It’s messy, not worth paddling out. Kite surfers might be having a ball, but for us, it’s a no-go.

Then, Thursday the 6th of August is where it turns on again. This is the other real standout, and this one’s for the experienced crew. We’ve got 7 ft to 8 ft SSW groundswell with a 14-second period, combined energy building to 2056 (strong). The wind is light offshore from the SSE at just 6 mph – clean, lined-up, powerful waves. This is excellent for experienced surfers. Friday the 7th is even bigger, hitting 8 ft with a 15-second period and energy at 2392 (very strong). The wind stays light cross-off from the SSE, but by afternoon the breeze picks up a bit. Still, clean wave faces for those who can handle the size. Saturday the 8th of August is similar – 7 ft to 8 ft SSW groundswell, glassy in the morning and offshore in the afternoon. Not one for the groms.

The last few days from Sunday the 9th onwards are a mix of messy onshore winds and a drop in quality, before a final clean-up on Tuesday the 11th of August with light offshore winds and a 4 ft SW swell, but the 8-second period means it’s on the weaker side.

Overall, Wednesday the 29th of July is your best bet for a friendly, clean session with decent waves. If you’ve got the skills and want power, Thursday the 6th to Saturday the 8th of August is the heavy-hitter window, but only for experienced surfers. The rest of the time is a bit of a gamble.

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.
