The Lowdown

Alright folks, Rusty here. Let’s have a look at what’s coming up at Koeel Bay.

We’re kicking off the outlook on Saturday, August 29th, with some small, clean waves. It’s not going to be a world-beater, but there’s a little bit of fun on offer. The overall pattern is a slow start, a solid pulse of good swell mid-week, then a long drawn-out tail of smaller, cleaner conditions.

Saturday morning we’ve got a 2ft south-west swell with a 14-second period. The energy is moderate (370). The wind is a light north-easterly, making it cross-offshore, so the reef should be handling that nicely. It’s a fairly consistent spot, but crowds can be a pain sometimes. The water temp is about average for this time of year. Saturday afternoon turns a bit lumpy with a south-south-westerly wind and a bigger 6ft swell, but it gets messy.

Sunday is a bit of a mixed bag. The morning is clean with a 5ft south-west swell (12 seconds) and a cross-off south-easterly breeze. Looks alright, but the afternoon wind picks up and kills the quality. Monday is a drop back to smaller, cleaner 4ft waves, better for a longboard.

Now, here’s where it gets interesting. Tuesday, September 1st, the swell starts to build, but it’s a bit of a tricky one. The wind is light and variable, but the report says "unknown" conditions, so treat it with caution. The real standout hits on Wednesday, September 2nd, in the morning. We’ve got a solid 7ft south-west groundswell, with a 13-second period. The energy is strong (1520). The wind is a light, offshore south-easterly, making it glassy and clean. This is the best on offer. It’s an intermediate wave, but at that size it’s for the experienced crew.

Thursday, September 3rd, the swell drops back but the wind gets real strong. Friday and Saturday, September 4th and 5th, see a big, messy, short-period wind swell develop. It is too big for beginners – over 8ft – and with a 7-8 second period, it’s just a wind-blown wall. The wind is screaming offshore, which for a beach or reef setup like this might actually be more interesting for the kite surfers than for paddle surfing.

Then we hit a lull. From Sunday, September 6th, through to Wednesday, September 10th, the waves are small – mostly under 3ft – but the wind goes light and glassy. It’s the kind of period where you’re just happy to be out for a paddle. The energy is weak (57-416). The water is about average for the time of year.

The second week shows a bit of promise again. The morning of September 13th (Sunday) has a clean 5ft south-west swell, light and glassy. That’s a nice end to the run. The forecast is less certain that far out, but it looks fun.

Bottom line: if you’ve got a window, Wednesday morning, September 2nd, is the one to chase. The 7ft south-west swell with offshore, clean wind is a proper session. The rest of the run is for the small-wave crew or the patient.

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.
