The Lowdown
Alright, Rusty here again, breaking down Blue Bay the Imperial way.
First couple of days, Saturday and Sunday (Sept 5th and 6th), are flat and weak. Not worth wetting your wetsuit. Swell is tiny, wind is messy, and the energy is hardly there. Forget it.
Monday morning, the 7th, is where it turns. We’ve got swell around 3ft out of the south, period at 9 seconds, and the wind goes glassy. That’s a gem. The combined energy is moderate (145), and the water is 66°, which is normal for the season. That Monday morning session is the early standout—clean, glassy, and the reef will be working. It’s inconsistent, so be patient, but the sets will be worth it.
Tuesday morning (8th) jumps to 8ft, but the wind is cross and the energy is strong at 1145. The chop makes it messy—more of a kiteboarding day than a clean surf session.
The real sweet spot comes Friday morning, the 11th, and Saturday morning, the 12th. Friday has 7ft south swell, 11-second period, clean cross-off wind, and solid energy at 1022. Saturday morning goes glassy again with 6ft south swell. Those are your best bets for the first week—clean, long-period groundswell, and the reef loves it. Crowds are only sometimes there, so you’ve got a shot at some solitude.
Then a gap from Sunday the 13th through Tuesday the 15th—small, weak, and not worth the paddle. That’s about three days of nothing.
But the second week fires up hard. Wednesday the 16th brings big swell at 12ft south, 12-second period, and massive energy at 6627. That’s serious power. Light cross-on wind, but at that size, it’s expert-only. The trend continues through Thursday and Friday (17th and 18th) with clean offshore winds and swell holding 10-13ft. The energy stays huge, well into the thousands. These are the standout days—big, clean, and powerful.
Sunday the 20th still has 10ft south swell, clean light cross-off wind, and excellent conditions for experienced surfers. A solid way to close it out.
So, skip the first weekend, hit Monday morning (7th) for glassy goodness, then lock in Friday and Saturday (11th and 12th) for the first week’s best. The real deal is from Wednesday the 16th through Sunday the 20th—big, clean, and unforgettable.
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.
