Alright, this is Rusty. Let’s have a look at what Koeel Bay has in store for us.

Right now, the pattern is that we’ve got a solid pulse of S/SSW groundswell coming through, but a lot of it is going to be blown out by strong ESE winds. Koeel Bay is a fairly consistent reef break that’s fairly exposed to this direction, and it handles a south swell well. The water temp sits at 59°F which is about average for this time of year.

The first real chance to get wet will be Saturday the 11th. It’s not the best, honestly. We’re looking at a 6 ft S swell at 12 seconds with moderate wave energy (1155), but that 16 mph ESE offshore wind is going to keep it clean, if a little on the raw side. You can surf it, but it’s not a standout.

Sunday the 12th is where things settle. Early morning, we’ve got 5 ft S swell at 11 seconds with light E cross-offshore wind at 6 mph. The wave energy drops to moderate (942) but it’s clean. Afternoon stays clean with a 5 ft S swell and light ESE offshore breeze. This is the best session of the first half of the week.

Monday the 13th is a glass-off day – 3 ft SSW swell with zero wind in the morning and 2 ft in the afternoon with barely a breath. It’s small and clean, but not a lot of power. Wednesday the 15th afternoon brings back some life – 5 ft SW swell with a long 16-second period, and glassy conditions. It’ll be clean and the energy jumps to 1271, but that long period might make it a bit tricky at a beach, though at Koeel Bay reef it’ll be fun.

Now, this is where it gets interesting. Friday the 17th, the swell pushes 8 ft from the SSW at 13 seconds with a fresh 19 mph ESE offshore wind. Wave energy is strong (2229). This is solid, big groundswell. Those 8 ft waves are for experts only, especially with that period. Clean, but big.

But the true standout is Saturday the 18th. Morning: 8 ft SE swell, 10-second period, ENE cross-offshore breeze at 6 mph. Wave energy is very strong at 2638. Afternoon: 8 ft SE, 10 seconds, glassy with a light east wind. The wind, the size, the consistency – this is the best on offer. It’s for experienced surfers only, but it’s a ripper.

From Sunday the 19th through Thursday the 24th morning, we hit a rough patch. Strong onshore winds and messy, choppy conditions, with swell sizes dropping to below 3 ft. There is a brief flash on Thursday the 23rd afternoon with a 5 ft SSW swell and 15-second period, but the cross-shore wind makes it marginal.

The run home gets better. Friday the 24th, we’re back to 5 ft SSW at 12 seconds with a gentle offshore SE breeze, clean. Saturday the 25th afternoon looks good too – 4 ft SSW at a very long 17-second period and a light cross-offshore wind, clean. Sunday the 26th afternoon stays clean with a fresh offshore SE wind and a 5 ft SSW at 14 seconds.

Crowds are possible here, so if you want the best without too much company, hit Sunday the 12th or keep an eye on Friday the 24th.

Stay safe, don’t get greedy.

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.

Koeel Bay is 18 km (11 miles) from the city of Grabouw. If you plan a holiday in Overberg, look for hotels and other accommodation in Grabouw. Grabouw has rooms for a wide range of budgets as well as car hire and transport links.
