The Lowdown
Alright folks, Rusty here. Let’s have a look at what’s cookin’ at Koeel Bay for the next couple of weeks.
Overall, this is a pretty tidy run of surf for a reef setup. We’ve got a bit of a slow start, but once it kicks in, there’s some real quality on offer. The water temp is sitting at 60°F, which is about average for the time of year, so no need to dig out the extra rubber just yet.
We start off on Monday, the 3rd of August, with a small but clean pulse. Morning glass, wind from the NNW at 3 mph, and a 3ft swell from the SW with a 13-second period. The energy is moderate (337). It’s not huge, but it’s clean and the reef should handle it. The afternoon stays tidy with a 3ft SW swell and a cross-off breeze, making for a decent session.
Tuesday the 4th is smaller, with a 3ft SW swell. The morning has a bit of cross-on breeze, but the afternoon goes glassy with zero wind, making it surfable but very ordinary. We’ll call it a lay day.
Wednesday the 5th is a write-off. Strong winds from the NNW at 15-19 mph, cross-on, and a messy 5-5ft swell. The energy is strong (1076-1033), but the wind will tear it apart. Kite surfers might have a ball, but for a paddle surfer, it’s a no-go.
Now, Thursday the 6th is where it gets good. The swell picks up to 6ft from the SW/SSW, and the wind swings to a clean cross-off and offshore. The energy is strong (1270-1267), and conditions are clean. This is a solid day for the intermediate crew.
Friday the 7th is the standout of the first week. This is the one to circle. The swell pushes to 7-7ft from the SSW, with a 14-second period, and the wind is offshore from the ESE at 9 mph all day. The energy is very strong (1809-1987). This is excellent surf, but at this size over a reef, it’s for experienced surfers only. The direction is right on the money for the optimum S direction, and the offshore wind will keep it glassy. Crowds are possible here, so get in early.
Saturday the 8th and Sunday the 9th drop off a bit. The swell hangs around 5-6ft, but the wind gets messy or onshore. Saturday has onshore winds, and Sunday has fresh southerly winds. The surf is marginal, so I’d give it a miss.
Monday the 10th brings a new pulse. A 7ft swell from the SSE with a moderate offshore wind (ESE 12 mph) keeps things clean. The energy is strong (964). The afternoon drops to 5ft, but still with offshore wind. A good day, but not as good as Friday.
Tuesday the 11th is a smaller but glassy gem. The swell is 5-6ft from the S, with light winds and glassy conditions in the afternoon. Clean and fun.
Now, Wednesday the 12th and Thursday the 13th are the real standouts of the whole forecast. Wednesday serves up a 4ft swell, but with a 20-second period from the SW. That’s a very long period groundswell, and on a reef, it’ll produce some beautiful, lined-up waves. The energy is strong (1201) and the morning is glassy. The afternoon bumps to 4ft with an 18-second period. Thursday the 13th is the bigger brother: 7ft from the SW with a 16-second period, and the energy is massive (2001). The wind is light or glassy all day. This is a serious session for experienced surfers. The long period will make the sets fat and powerful, and the reef will hold it beautifully.
Friday the 14th is still very good, with 5-6ft SW swell and clean conditions, but the energy drops back a bit.
The weekend of the 15th and 16th of August is smaller and cleaner. Saturday the 15th has a 4-4ft SW swell, with glassy afternoon conditions. Sunday the 16th bumps back up to 5-5ft SW swell with a 14-second period and clean conditions. Good for a cruise.
Monday the 17th and Tuesday the 18th are a wrap. The wind cranks up from the NNW at 15-25 mph, cross-on, and the swell drops. The last few days are blown out and messy. Time to hang up the board.
So, the best on offer? Friday the 7th for the first big offshore pulse, and then Wednesday the 12th and Thursday the 13th for the long period groundswell. The 13th is the biggest and most powerful of the lot, but it’s strictly for the experienced crew.
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.
