The Lowdown
Alright, let’s switch it up to imperial for you landlocked folks. Rusty here, same story, different numbers.
It’s a quiet patch for Blue Bay. We’re looking at a long stretch of small, messy surf before anything decent shows up.
The first few days are a bust. From Friday the 21st through Tuesday the 26th of August, the swell is tiny—mostly around 2 to 3 feet, with short periods of 6 to 8 seconds. The wind is a mess, switching from cross-off to onshore. The wave energy is weak, with readings in the double digits (51, 26, 9). The water temp is 64°F, which is about normal for this time of year.
There’s a small window on Sunday the 23rd morning. A glassy morning with a 3ft south swell rolling in at 11 seconds. That longer period gives it a bit of push, but the energy is still moderate (253) and the break is inconsistent. It’s surfable, but only just. Beginners might be okay, but it’s not a call-out.
The real standout hits on Monday the 31st of August. The morning shows a 5ft swell from the ENE with a 7-second period, and the wind is offshore from the WSW, keeping it clean. The wave energy jumps to 584, which is strong. Blue Bay is a reef, and while the swell direction is a bit off the optimum SSE, that offshore wind will make it glassy. It’s a solid intermediate wave. The afternoon drops to 5ft, but stays clean.
The rest of the first week of September fades back into weak, small surf with lousy winds. There’s a glassy morning on the 5th of September, but the swell is only 2ft with weak energy (101). It’s ordinary.
Your one to circle is Monday the 31st of August morning. That’s the pick of the bunch.
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.
