Alright, Rusty here. I’ve been going over the long-range for Koeel Bay, and I’ll tell you straight – the start is a write-off.
This morning through the weekend is a no-go. The wind is all cross-onshore. Friday morning has a 30 km/h cross-onshore, lumpy, with a tiny 3ft swell. Saturday and Sunday are the same story – windy, choppy, wave energy all over the place (265, 247, 169, 233, 154, 494). There’s a solid gap of a few days where you won’t want to be out there.
The first real surf comes on Monday the 6th. Monday morning the wind switches offshore from the SE at only 5 km/h, and the swell cleans up to a nice 4ft from the SW with a 12-second period. The combined energy is 475 – moderate, but the conditions are the real story. By Monday afternoon it goes glassy with that same 4ft SW swell. Tuesday the 7th is a dream – glassy all morning, no wind, 4ft SW swell, energy at 455. These two days are the standout window in the first week. Clean lines, good for intermediates, and that reef will work. Crowds are “sometimes,” so you might share it, but it won’t be a zoo.
Midweek gets challenging. Wednesday the 8th sees the swell building to 5ft-6ft, and the energy jumps into the strong range (1467, 1591), but the wind and tide look questionable. Thursday the 9th is bigger – 8ft swell from the S – but the wind is a moderate offshore at 25 km/h. Clean, but that size is for experts only. The energy is very strong (2341, 1956).
The second week is promising. Friday the 10th has very good conditions with moderate offshore winds and 5ft-5ft SSW swell. The real long-range standout, though, is Friday the 17th of July. We’re looking at a glassy morning with a 8ft SSW swell, 14-second period, and strong wave energy at 1942. The forecast calls it excellent for experienced surfers. That’s one to mark on the calendar, but it’s far out, so don’t plan your life around it yet. Saturday the 18th also goes glassy with a smaller 5ft swell to close out the run.
Water temp is average for the season, nothing unusual.
So, your best bets are Monday the 6th through Tuesday the 7th for the win, and keep an eye on that Friday the 17th window – it could be the best of the whole run.
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.
