Updates in hr min s Forecast update imminent
Alright folks, Rusty here. Let’s break down what Koeel Bay is serving up over the next couple weeks.
We’re starting off slow – nothing worth paddling out for until Wednesday afternoon, 8th July. That’s when it wakes up.
Wednesday arvo sees a 6ft swell from the SW with a super long period of 16 seconds – proper groundswell energy, reading 2701 for combined energy. Winds go cross-offshore from the south at about 9 mph, keeping it clean. That’s a solid, powerful wave, best left for the experienced surfers. The water’s sitting around 58°, which is a bit colder than usual for July, so you’ll want a thick wetsuit.
The real standout is Thursday 9th July. Morning brings 7ft of SSW swell with a 14-second period and a strong offshore breeze from the southeast at 12 mph. Clean, lined-up, and powerful with 1487 energy. This is the best window – expert-only territory, but absolutely firing.
Friday the 10th is nearly as good: 7ft SSW in the morning, dropping to 6ft in the arvo, both with clean offshore winds. Crowds are only occasional here, so you might score some empty waves.
Saturday the 11th is still clean but smaller at 5ft, with a gentle offshore breeze.
Then it goes quiet from Sunday the 12th to Wednesday the 15th – mostly small, choppy, or onshore. Not worth the drive.
Thursday the 16th brings a bit of hope: 4ft in the morning with an offshore breeze, building to 6ft in the afternoon with clean cross-offshore wind. Not a huge standout, but a decent session.
The rest of the forecast from Friday the 17th onward is mostly cross-onshore winds and small swell. You get a glassy moment on Sunday the 19th with 4ft, but it’s not the same juice as that Thursday high.
So if you’re picking your days: Thursday 9th July is the absolute winner. Big, clean, offshore. Wednesday the 8th is a strong second if you prefer long-period power. Everything else is small, messy, or average. Keep your eyes peeled on the 16th, but don’t hold your breath.

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.
