The Lowdown
G’day, I’m Rusty. Let’s talk about Blue Bay surf. The next couple weeks start off real slow, but there’s a big-time swell late in the game that’s worth marking on the calendar.
Water temp is around 64°F, pretty much average for this time of year. Nothing unusual.
From Tuesday 18 August, it’s mostly small and junky. Tuesday afternoon has a weak 4ft ESE swell with a short period of 7 seconds, onshore wind, and combined energy at 262—just poor. Wednesday morning drops to 3ft but the wind goes glassy, so it’s clean but tiny—surfable but nothing special. That’s the highlight for a while. Through Thursday, Friday, and the weekend, we’re looking at tiny waves from 1ft to 3ft, mostly short period and weak. A few windows are clean or glassy, but there’s no real push. Total lull.
Monday 24 August sees a little life with a south swell at 2ft, period up to 10-11 seconds. Clean cross-off wind, combined energy at 113 (moderate). Still just surfable and ordinary.
Then we go flat and small again until the end of the month. A lot of days with combined energy under 100 and messy winds.
Then, Sunday 30 August—watch out. A heavy groundswell shows up. Morning brings 8ft south swell with a 18-second period—that’s proper long-period energy, and the combined energy hits 6612 (strong). Wind is light and cross-off, so it’ll be clean. This is experts only—well over 8ft. Beginners, stay onshore. Blue Bay is a reef, and with that long south swell aimed right at the optimum SSE direction, it’s going to handle that long period well. The afternoon stays huge at 12ft but gets a cross-on breeze, making it less ideal.
Monday morning 31 August drops to 6ft, glassy, with combined energy at 1108—still excellent for those who can paddle it. Then it tapers off into smaller, cleaner conditions through early September.
So yeah, the first week and a half are quiet. But that Sunday-Monday blast at the end of August is the real deal—big, clean, and for experts only. Don’t miss it if you’ve got the skills.
Catch ya,
Rusty

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