The Lowdown
Alright folks, Rusty here. Let’s have a look at what’s cookin’ at Koeel Bay over the next couple of weeks.
First up, we’ve got a solid run of surf starting this Sunday, the 23rd of August. The bay is a reef setup, so it can handle a bit of juice, and it’s fairly consistent. The water temp is about average for this time of year, nothing crazy to report there.
Sunday morning kicks off with a clean 4ft SW swell, period a solid 13 seconds – that’s real groundswell energy. Wind is light and cross-offshore from the S at 6 mph, so the face will be smooth. The combined energy is a moderate 581. It’s a nice start, but the score is a bit average due to tide, so don’t expect perfection.
Monday morning, the 24th, drops a little to 4ft, still SSW, with a cross-offshore breeze. It’s clean but marginal. The energy is down to 470. Not a standout.
Tuesday the 25th is where it gets interesting. The morning sees a clean 5ft SW swell with a long 14-second period. The wind is offshore from the ESE at 16 mph, making for some clean, lined-up walls. The combined energy jumps to a strong 1032. There’s a bit of breeze, so it’s not glassy, but it’s good. The afternoon stays offshore but gets a bit fresh, still clean.
Wednesday the 26th is a real gem. Morning brings a 3ft SSW swell, 12-second period, with a moderate offshore breeze from the E at 12 mph. The afternoon is even better: 4ft, same direction, with a gentle offshore from the ESE. The energy is a solid 880. This is clean, fun surf – a true standout for the week.
Thursday the 27th and Friday the 28th stay clean, with the swell dropping to 4ft and then 3ft by Friday, but the wind turns glassy on Friday. That’s a morning glass-off with a 4ft S swell – perfect for a longboard or a fish. The energy is light, 370, but it’ll be a treat.
We hit a lull on the weekend of the 29th and 30th. Saturday is a write-off with onshore wind and a tiny 2ft swell. Sunday the 30th has a bit more size at 5ft, but the period is a short 8 seconds, and the wind is cross-shore. Not worth the paddle.
Monday the 31st sees a return to cleaner conditions with a 4ft to 4ft SW swell, 12-second period, and cross-offshore winds. It’s clean but not firing.
Now, looking ahead to the first week of September, things get serious. Tuesday the 1st of September has a 6ft SW swell with a 14-second period, but the wind is cross-onshore in the morning and onshore in the afternoon. Tough to get excited about.
Wednesday the 2nd of September is the big one. Morning has a 8ft SW swell, 14-second period, and the wind is cross-onshore with light rain – not great. But the afternoon is a beast: same 8ft swell, offshore wind from the SE at 9 mph, and the combined energy is a massive 2551. This is expert territory, steep and powerful, but if you’ve got the skills, this is the best session of the whole forecast. The swell is big, but it’s a reef, so it should hold.
Thursday the 3rd and Friday the 4th are messy. Big swell, but onshore or cross-onshore gales. Kite surfers might have a field day, but for paddle surfing, it’s a no-go.
Saturday the 5th of September brings a clean 8ft SSW swell, 14-second period, with a fresh offshore breeze from the ESE at 19 mph. The energy is a massive 2904. The wind is strong, making it hard to paddle into, but the waves will be huge and clean. Only for the very experienced.
Sunday the 6th and Monday the 7th are a mixed bag. Sunday has a 5ft swell but cross-onshore wind. Monday the 7th sees a massive 13ft SW swell, but the report says it’s too big for this break. The energy is a whopping 7471. Don’t even think about it.
So, to wrap it up: the best windows are Wednesday the 26th of August for a clean, fun run, and the absolute standout is Wednesday afternoon the 2nd of September for the big, clean, offshore swell. That’s the one to circle on the calendar. The rest of the first week of September is either too big, too windy, or both.
Stay safe out there.
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.
