The Lowdown

Alright, this is Rusty, your local surf reporter, coming to you straight from the beach. Let’s get into it.

Alright, we’ve got a solid run of surf coming up at Koeel Bay, a reef break that’s fairly consistent and handles a south swell really well. The water temp is sitting about average for this time of year, so nothing weird there. The big highlight is Monday, July 27th, with a proper pulse of swell. We’re looking at a 7 ft SSW groundswell with a long 17-second period, generating a serious amount of energy (2349). That’s a big, powerful swell – definitely for experienced surfers only, as it’s over 5 ft. The wind is offshore from the SE at 12 mph, keeping things clean and lined up. That’s the standout session of the whole forecast.

The run-up to that is good too. Sunday, July 26th, starts us off with a 5 ft SW swell (11-second period) and glassy conditions in the morning. Clean, chest-high waves with moderate energy (727). By the afternoon, the wind shifts to a cross-offshore, but it’s still clean. Then Monday afternoon, the swell sticks around at 6 ft with a fresh offshore breeze, but the wind is a bit stronger at 19 mph. Still a great option for the experienced crew.

Tuesday, July 28th, holds onto the swell, around 6 ft from the SSW, but the wind cranks up to 22 mph offshore. It’s clean, but that’s a strong breeze, making it a bit more of a handful. The wave energy is still high (1367-1472), but it’s a bit too windy for perfect conditions.

Wednesday, July 29th, is a nice little breather. The swell drops to 4 ft, but the wind goes glassy. It’s a morning glass-off with a 13-second period SW swell. Good for a longer board, fun, clean waves. The energy is moderate (642).

We hit a bit of a lull after the first week. The swell drops off significantly by the start of August, with tiny 1 ft to 2 ft waves. Not much to write home about for a few days. It picks up again on Sunday, August 2nd, with a 5 ft SSW swell, but the period is a very long 18-19 seconds. That’s a groundswell, and it’s likely to be a bit too straight for the reef, making it tricky. The wind is cross-offshore, so it’s clean, but the wave shape might be a bit weird.

The forecast gets a bit more uncertain out past the 7th. There’s a bigger swell showing up around Saturday, August 8th, with 8 ft to 8 ft from the SW. That’s a big, powerful swell, but the wind is looking cross-onshore or onshore, which will mess up the quality. The energy is very high (1837-2222), but it’s only for experts with a tolerance for chop. The week following that is smaller, with clean conditions and glassy mornings, but nothing explosive.

So, to sum it up: Monday, July 27th, morning is the absolute stand-out. Big, clean, powerful groundswell. If you’re experienced, that’s your window. The Sunday before and the Wednesday after are also solid, clean options. The very end of the forecast has a clean, smaller window, but it’s a long way out.

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.
