Table - best surf conditions forecast for Koeel Bay over the next 16 days.
Let’s talk about Koeel Bay. The first 16 days have a mixed bag, but there’s plenty to get excited about if you know when to go.
Kick off Wednesday morning with a glassy, clean 5ft SW swell, 13-second period, and the wind is dead calm out of the NW. Perfect. Water temp is 59°F, about average for the season. The combined swell energy is moderate (958). Wednesday afternoon the wind picks up SSE, goes cross-off, and the swell bumps to 6ft with a long 16-second period – strong energy (2736). Clean, but those long lulls will test your patience if you’re used to faster sets.
Thursday and Friday mornings are where it gets serious. Thursday morning: 7ft SSW swell, 14 seconds, offshore SE breeze at 12 mph, strong energy (1628). This is expert territory – over 5ft, so no place for beginners. The direction is ideal for the reef. Friday morning repeats: 7ft, 13 seconds, offshore ESE at 12 mph, strong energy (1506). Both mornings will be firing.
Saturday holds at 6ft in the morning, easing to 5ft by the afternoon, still offshore, clean.
Sunday drops to 4ft morning, then 3ft afternoon, glassy. Small but clean.
Then Monday through Wednesday of the next week it goes tiny – 2ft down to 1ft. Wednesday the 15th is a disaster with onshore winds up to 28 mph and rain. That’s four days of flat, messy conditions.
Thursday the 16th sees a swell jump to 7ft then 8ft, with very strong energy (4147 in the afternoon), but the wind is onshore, rain, and it’s rated poor. Don’t bother.
Now the second big window. Friday the 17th morning: glassy, 7ft SSW swell, 12 seconds, strong energy (1227). That morning will be clean and powerful.
Saturday the 18th is a bit tricky – morning has cross-shore wind and 7ft, but the afternoon turns glassy with 6ft S swell and 12 seconds. That afternoon is a hidden gem.
Sunday onwards the wind goes ugly again, and the swell fades.
But the final standout is Tuesday the 21st afternoon: 5ft SSW swell, 14 seconds, gentle offshore at 9 mph, clean. Then Wednesday the 22nd morning: glassy, 7ft SSW swell with a 15-second period – very long period groundswell – and strong energy (1945). This is the session to aim for. Glassy, big, perfect direction. It’s for experts only, and the long period might make it a bit walled on the reef, but it’ll have power to burn.
Crowds: Koeel Bay can get busy, especially on these standout days, so expect company.
Best bets: Wednesday morning 8th July, Thursday and Friday mornings 9th-10th, and the crown jewel – Wednesday 22nd July morning.

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.
