The Lowdown
Alright, let's talk about Koeel Bay in feet and miles per hour. The first few days are a write-off – no surf worth paddling for until Tuesday 21 July. Water temp is about 59°F, which is normal for this time of year.
On Tuesday 21 July morning, the ocean goes glassy with a light offshore breeze. Swell is 5.6ft from the SSW, 14-second period – that's some long-period groundswell. Combined energy is strong (1099), so you'll feel the power. Clean conditions, but crowds can show up, so get out early.
Thursday 23 July afternoon: a 3.6ft SSW swell with a 19-second period (combined energy 1184). Light cross-onshore wind, a bit bumpy but still fun.
Now the real standout is Friday 24 July. Morning: glassy, 7.5ft SSW swell, 15-second period, combined energy 2274 – huge energy. This is for experienced surfers only; too big for beginners. Afternoon: 6.9ft with clean cross-offshore wind. Perfect.
Saturday 25 July: 5.6ft SSW, gentle offshore breeze from ESE, clean. Combined energy 1016. Crowds possible.
Tuesday 28 July morning: another excellent session – 5.6ft SSW, 15-second period, offshore east wind, combined energy 2148. Clean and powerful.
Thursday 30 July: fresh offshore wind all day, 7.2ft SSW swell, wind a bit strong but still clean.
Saturday 1 August morning: 9.8ft SE swell, shorter 8-second period, combined energy 1555. Light breeze, clean – only for experts. Afternoon: glassy, 7.9ft SSE.

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.
