The Lowdown
Alright folks, Rusty here. Let’s break down the next couple of weeks at Koeel Bay.
We’re starting off with a solid push of SSW groundswell. Saturday morning the 25th has a 1.8m SSW swell with a 13-second period and the combined energy is pumping at 1649 (moderate to strong). The wind is light offshore from the SE. It’s clean and has some punch, but this is a reef break best for intermediates. The morning is the session; the afternoon gets a bit scrappy.
Sunday the 26th of July is a real gem. The wind goes completely glassy in the morning – dead calm. The swell drops to 1.4m from the SW at 11 seconds, with an energy of 727 (moderate). It’s not massive, but it will be pure, smooth, and rippable. Water temperature is about normal for this time of year. That’s your session for clean lines.
Monday the 27th brings size. We’re looking at 1.8m to 2.1m SSW swell with a long 17-second period. The energy jumps way up (1955 to 3005 – strong). Winds are a fresh offshore from the SE at 30 km/h. The faces will be clean, but that wind will make it a workout. It’s big and powerful, strictly for experienced surfers.
Tuesday the 28th holds at 2.1m from the SSW, period at 15 seconds, and energy in the 2126 to 1970 range (strong). Offshore winds from the ESE continue. Still quality, but serious.
Wednesday the 29th and Thursday the 30th see a drop in size. Swell backs off to 1.3m down to 1.0m, with glassy mornings. Energy sits between 325 and 789 (moderate). Good for smaller boards or a longboard, but not the standout.
Friday the 31st through Saturday the 1st of August is pretty much flat. Swell under 1.0m and onshore winds. Energy is weak, below 300. Not worth it.
Then Sunday the 2nd of August fires up. We get a 1.5m SSW swell with a 16-second period and glassy conditions. Energy at 1386 (moderate to strong). That’s a top contender for the best day – clean, solid, and well-formed.
Monday the 3rd and Tuesday the 4th are mostly cross-onshore junk, poor conditions. But Wednesday the 5th of August has a sneaky good morning. A tiny 0.7m swell but with a very long 21-second period and energy at 799 (moderate). Clean and wrapped in. The afternoon of the 5th is a standout: glassy conditions and a 1.8m swell from the SW with an 18-second period and energy at 2090 (strong). That is a serious wave for experienced surfers.
Thursday the 6th and Friday the 7th see big 2.5m to 3.0m SSW swell with onshore winds. Only for the experts, and choppy. Saturday the 8th recovers with a clean 1.7m to 1.8m SSW swell and light winds, good to end on.
Best bets: Sunday the 26th and Sunday the 2nd for clean, manageable waves. Wednesday the 5th afternoon for a big, clean groundswell pulse.
Rusty out.

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.
