The Lowdown
Alright folks, Rusty here. Let’s have a look at what the next couple of weeks are serving up for Koeel Bay.
We’ve got a real mixed bag on the horizon. The pattern kicks off with a nice run of clean, manageable surf, then the ocean takes a bit of a breather before firing up again with some serious size for the experienced crew. The first week is where you want to be if you’re after user-friendly waves, but that second week holds some proper groundswell that’ll get the heart pumping.
Thursday, July 30 is a solid start. Koeel Bay is showing clean, glassy conditions with a 3.6ft SSW groundswell (13-second period). The combined swell energy is moderate (490), so there’s enough push to get into a nice, long wall. Wind is dead calm in the morning, turning light offshore in the afternoon. This is a proper fun day for intermediates.
Friday, July 31 keeps the good times rolling. Morning glass with a 2.6ft SW swell (12s), building into the afternoon with a 3.6ft SE windswell (8s). The combined energy drops a little (323 to 299), but the conditions remain glassy and clean all day. Another day of clean lines.
Saturday, August 1 is a bit of a letdown. The swell is small – around 2.3ft to 2.6ft – and the energy is weak (227 to 231). It’s glassy and clean, but the waves are ordinary. You might get a knee-high runner, but it’s a day for a longboard or a paddle.
Sunday, August 2 is a write-off. The wind swings cross and cross-onshore, making the 2.6ft swell messy and bumpy. Combined energy is low (220-228). Not worth paddling out.
Monday, August 3 is a return to form. Morning glass with a clean 3.0ft SW swell (13s) and moderate energy (270). By the afternoon, we’ve got a 3.3ft swell and light cross-offshore wind keeping it clean (358). This is a sneaky good day.
Tuesday, August 4 is another poor one. Cross-onshore winds kill the 2.6ft swell (185-186). Leave the board at home.
Wednesday, August 5 gets messy. The swell jumps to 6.2ft-6.9ft from the SW, but the energy is strong (1656-1937) with a fresh cross-onshore wind. The ocean is lumpy and onshore. This setup is more interesting for kite surfing than paddle surfing, so save your energy.
Thursday, August 6 is where it gets serious for the experienced surfer. The swell is 6.9ft to 7.9ft from the SW (13-14s), with strong to very strong energy (1430-2996). The morning sees light offshore winds keeping it clean. This is big and powerful – experts only, and you’ll want to be on a step-up and be comfortable paddling into sizable waves. The long period (13-14s) means longer waits between sets, so patience is key.
Friday, August 7 is bumpy and challenging. The swell is 7.5ft-8.2ft (very strong energy at 2699-2155) but the wind is onshore and cross-onshore. It’s big, messy, and not worth the effort even for experts.
Saturday, August 8 drops off in size (4.3ft-4.9ft), but the moderate cross-shore wind makes it a choppy, messy day. Not recommended.
Sunday, August 9 is a standout for the big-wave hunters, but with a huge caveat. The swell is pumping at 14.8ft to 16.4ft from the SW (14s), with extreme energy (8713-9985). Winds are moderate offshore and clean, which would be perfect… if the wave wasn’t predicted to be too big for Koeel Bay. This is a monster. This is for the absolute elite only, and even then, it might be closing out completely. Very long period (14-15s) at a reef break means it could be a walled-up, dangerous beast.
Monday, August 10 is another big day for experts. Swell is a solid 9.8ft from the SSW (13s

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.
