The Lowdown
Alright, let me break down Blue Bay for the next couple of weeks.
The start is rough – Monday the 10th through Tuesday morning the 11th are a total washout with rain and strong winds. The water’s at 18°, which is about normal for this time of year, nothing wild.
First real chance comes Tuesday afternoon the 11th. Light cross-off wind, a 1.4m south swell with a 12-second period – that’s proper groundswell. The energy’s moderate (620), and the wind is super light, so it’ll be clean. This is the first standout.
Wednesday the 12th is just okay. Thursday the 13th sees the swell jump to 2.1m in the morning and 2.5m in the afternoon. That afternoon has a ton of energy (2210), but the cross-shore wind will chop it up. That size is expert-only.
Friday the 14th morning is clean with a 1.5m south swell and light offshore wind. Decent, but not a standout.
Then we hit a flat spell from Saturday the 15th through Monday the 17th morning – mostly poor, small, short-period swell and messy winds. Monday afternoon gets worse with onshore winds.
Tuesday the 18th and Wednesday the 19th are also poor – rain, onshore winds, bumpy sea. The swell is there (1.8m to 2.0m), but it’s not clean.
Now, the real gems. Thursday morning the 20th of August – glassy conditions, light offshore, a clean 1.4m east swell with an 8-second period. Perfect. Then Friday morning the 21st – again, glassy, calm winds, a 1.4m east swell with a 9-second period. Moderate energy (289), but with those glassy conditions, it’ll be a dream. Crowds might show up sometimes at Blue Bay, but with weather like that, it’s worth it.
Sunday the 23rd afternoon brings a decent offshore wind and a 1.5m east-northeast swell with an 11-second period – long period groundswell. Clean conditions, good energy (479).
Finally, Tuesday morning the 25th – a clean 1.5m east swell with a 12-second period, gentle offshore wind, and very good surf expected. This one’s the standout of the second week. A week and a half out, so keep your fingers crossed, but it looks like a cracker.
Bottom line: skip the first few days and the middle of the second week. Hit Tuesday afternoon the 11th, Thursday morning the 20th, Friday morning the 21st, and Tuesday morning the 25th. Those are your windows.

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.
