The Lowdown
Alright, folks, Rusty here. Let's talk about what's on the menu at Blue Bay. It's a bit of a lean stretch ahead, so let's get into it.
We're looking at a pretty quiet start to this 16-day window. For the first week and a half, from Saturday the 15th of August right through to Saturday the 22nd, it's pretty flat and messy. The wave energy is weak, mostly under 200 (combined energy), and with a lot of cross-onshore and onshore winds, you're not missing much. There's a little window on Wednesday the 19th morning with some glassy, knee-high waves from the SE, but it's pretty ordinary. Honestly, the swell is small and the wind is working against us for most of that stretch.
The second half of the period is a different story, but it's one for the brave. The real standout comes right at the very end. On Saturday the 29th of August, we get a big pulse of S swell. The morning sees a massive 18 ft swell from the south with a 13-second period and a massive energy reading of 18292. The wind is a moderate cross-onshore, so it's going to be lumpy and choppy. That's expert-only territory, and it's not going to be a pretty picture. The afternoon settles a bit, dropping to 15 ft with a cross-shore wind, making it a little more manageable but still a huge, powerful groundswell with a long period. This kind of long-period swell can make for tricky, walled-up waves at a beach break and is better suited to a reef or point. Blue Bay is a reef break, so it could handle it, but the size and the wind are a big caveat.
Sunday the 30th of August eases off to a still-chunky 10 ft from the SSE with a moderate 11-second period, but the wind is still cross-onshore, so condition-wise it's marginal.
So, the only real standout to talk about is that massive pulse on the 29th. It's a huge, powerful, and dangerous day of swell. If you're an expert on a big-wave board, it's the only real show in town, but it's far from clean. The rest of the window is a write-off for decent surf. The water is sitting at 63°, which is a bit colder than average for this time of year, so don't forget the booties.
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.
