The Lowdown

Alright, let’s get into it.

The next couple of days are a total washout, so don’t even bother waxing up until Thursday. We’ve got a solid pulse of swell coming, but it’s going to take a little while for the wind to play nice. Once it does, we’re in for a couple of proper sessions, especially if you can get out around Friday.

Wednesday is a complete loss. The northwest wind is howling and lumping up the surface. You’d be fighting a losing battle out there. Don’t waste the energy.

Thursday morning is where it starts to get interesting. We’ve got a solid 7ft SW swell rolling in with a 13-second period, and the wind swings around to a light southeast cross-offshore. The water is a touch cooler than average for this time of year, sitting around 59°. Koeel Bay (Big Island) is the spot. The energy is building too, with the combined swell energy reading 1528, which is solidly in moderate territory. It’s going to be a bit much for beginners at this size, but for the experienced crew, it’s clean and pushy. Thursday afternoon drops off a little in quality, with the swell period shortening and the wind picking up a notch.

But Friday is the standout. Both morning and afternoon are looking prime. The swell holds around 7ft to 8ft from the SSW, and the period stretches back out to 15 seconds. That’s proper groundswell, and it’s going to have some serious push. The morning is clean with a light cross-offshore breeze. But the afternoon, with the wind dropping to glassy, is about as good as it gets. The combined swell energy jumps up to 2268, which is strong. This is the session to plan your day around. The waves will have real shape and power, ideal for the reef setup. This is expert territory at this size, no doubt.

Saturday is still worth a look, but it’s a step down. The morning is glassy with a 6ft SSW swell, but the energy drops back. The afternoon brings a bigger 8ft swell, but the conditions get a bit tricky. The wind goes cross-shore and creates ripples. The energy is there, but the quality drops. It might be a bit of a war zone.

Sunday gets blown out. The wind swings around to a strong southeast and it’s howling. The swell is still there, but it’s going to be messy. The strong cross-offshore wind is going to make it hard to paddle out and the waves will be all over the place. You can forget it.

Monday is all about a strong offshore wind, which is a double-edged sword. The swell drops off a bit, and the period shortens. The wind is howling, making it nearly impossible to get into the waves. It’s going to be a battle just to get out the back. Not worth the effort for a surf.

After that, we hit a lull. The middle of next week is pretty weak. There are some small, clean waves around Tuesday, but they’re not going to get the heart racing. The swell is down around 3ft to 5ft.

The following weekend, around the 15th and 16th, we see a small but clean run of waves. The swell is small, but with light winds and glassy conditions, you could find a few fun ones if you’re desperate. It’s not going to be anything special.

Looking further out, about a week and a half from now around the 19th, there’s a glimmer of hope. The wind looks to go offshore again, but the swell is tiny. It’s a long way off, so don’t get too excited. For now, focus on Friday. That’s the day.

This next stretch isn't looking great. After the initial burst of energy, we're looking at a lot of small, weak surf. It's a bit of a bummer, honestly.

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.
