The Lowdown
Alright, Rusty here, let's talk about what's on the cards for Coolum Beach.
Look, I'm not gonna sugarcoat it. The next week or so is pretty flat and ordinary. We’ve got a long dry spell ahead. The first real chance of a wave that’s worth paddling for doesn't show up until the morning of Monday the 31st of August. That’s about an 8-day gap with nothing to write home about. There’s bits and pieces of knee-high slop, sure, but the wind’s in the wrong spot or it’s just too weak to get excited about. The water temp is sitting at 68°, which is about 2° colder than normal for this time, so you’ll want a decent spring suit.
The standout, and really the only window, is the morning of Monday the 31st. We’re looking at a clean push of swell from the SSE, with a height of 6 ft. The combined energy is strong at 338, so there’s some proper grunt behind it. The wind is light and cross-off from the SSE at 6 mph, which should keep the faces clean. It’s a beach and reef setup, so on that size, it’ll be a bit too much for beginners, but for the experienced crew, it’s the best offering in the whole 16-day run. The swell period is a short 6 seconds, so it’s windswell, not a long groundswell, but beggars can’t be choosers. Crowds are sometimes an issue here, so get there early.
After that Monday morning window, the following week drops back into the doldrums. The surf gets smaller, the wind goes onshore out of the north, and it just fades away. The last few days of the forecast into the first week of September are looking tiny, with energy readings dropping below 100, so it’s going to be a quiet time on the sandbars.
Best bet: Monday 31st August morning, but keep an eye on it – it’s the only real chance in the pack.
Rusty.

Information about the Coolum Beach Surf forecast
The above surf forecast table for Coolum Beach provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Coolum Beach can be found by selecting the local surf guide option on the grey menu. Our Coolum Beach 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 (Coolum Beach) 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 Coolum Beach 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.
