The Lowdown
Alright, this is Rusty. Let’s look at Blue Bay for the next couple of weeks.
Right off the bat, we’ve got a bit of a quiet start. The first surfable window doesn’t really open up until Tuesday afternoon (August 11th). Before that, it’s small and not worth the paddle.
The standout moment comes on Tuesday afternoon (August 11th). The bay gets a 5ft groundswell from the south, with a long 11-second period. That’s proper energy rolling in – combined energy is a moderate 638. You’ve got a light offshore wind out of the WNW at 12 mph making it clean. For a reef break that’s inconsistent, when it turns on like this, it’s special. The water is sitting at 64°, which is about 1° cooler than average for this time of year – nothing crazy, just a touch on the fresh side.
Wednesday morning (August 12th) holds some clean 4ft south swell, but it’s not quite the same punch as Tuesday. After that, conditions start to slide. The wind swings around and gets messy from Thursday through the weekend. There’s a pulse of 6-7ft south swell on Thursday afternoon, but it’s cross-onshore and choppy, and the combined energy is a big 1095 – plenty of power, but it’s a messy and challenging setup. For beginners, that 5ft+ is already pushing it.
We get a glassy morning on Friday (August 14th) with 3-4ft south swell, but it’s pretty ordinary.
From late in the first week into the second week, there’s a long stretch of cross-onshore winds and poor conditions, with swell mostly in the 5ft to 7ft range. The beach-and-reef setup here with those strong onshore winds looks more interesting for kite surfing than paddle surfing through this period.
Finally, there’s a flicker of hope late in the outlook. Saturday morning (August 22nd) sees a clean 4ft swell from the ENE with a moderate offshore wind – decent, but nothing to write home about. The real potential is on Sunday morning (August 23rd): a 6ft ENE groundswell at a 10-second period, with offshores. That combined energy hits 1207, which is strong. It’s rated as marginal for tide reasons, but if you hit the right tide, this could be the best of the second week. That one is promising but less certain being so far out.
Rusty, signing off.

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.
