The Lowdown
Alright, folks. Rusty here, breaking down the next couple of weeks for Koeel Bay. This reef is a consistent spot, and we've got a serious run of swell coming our way.
The start of the week is a bit of a washout. Sunday and Monday are looking pretty average with cross-onshore winds and small, weak surf. The water temp is about normal for the season at 59°F.
Then, the whole picture changes. Tuesday, July 21st is the first day of the real action. We're looking at a solid SSW groundswell, 6ft to 6ft, with a long 14-second period. The energy is massive (1311-1341), and the wind is going glassy in the morning, turning clean offshore in the afternoon. This is the real deal. It's a bit big for beginners, but it's going to be incredible for the rest of us. The swell direction is a perfect match for the spot.
The quality keeps going through the end of the week. Thursday afternoon, July 23rd, and Friday, July 24th, are the true standouts. Thursday afternoon brings another glassy session with 6ft SSW swell (1209 energy). Friday morning, the swell punches up to 8ft (2330 energy) with a 14-second period, again from the SSW. That's big, expert-level surf, but with clean, offshore winds, it'll be some of the best waves of the season. Saturday, July 25th, still has strong offshore winds and a solid 6-7ft SSW swell, but the wind picks up a bit.
The second week has some good moments too. Tuesday, July 28th, is another one to watch. The morning is glassy with an 8ft SSE swell (1719 energy), and the afternoon stays clean. That's serious power. Wednesday, July 29th, also has a glassy morning with 8ft swell, but the period drops to 8 seconds, making it a bit mushier. The very end of the run, into early August, has some smaller, clean, glassy days, but it's a step down from the main event.
So, the best on offer is clear: Tuesday, July 21st through Friday, July 24th. The absolute standout is Thursday afternoon and Friday morning. That combination of long-period SSW groundswell, clean to glassy conditions, and that raw energy is what makes a reef break like this come alive. Expect some company, as crowds are "sometimes" a thing here. Get on it.
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.
