The Lowdown
Alright, let’s get into it. The 16-day window ahead of us is a bit of a slow burn. First solid opportunity worth getting excited about doesn’t arrive until the very end of the month. Right now, we’ve got a long dry spell with small, weak, and messy surf. The few moments of glassy conditions early on still only deliver tiny, unexciting waves. Expect a real gap in quality until we hit the start of September.
Water temperature at Blue Bay is sitting at 64°F, which is about what you’d expect for this time of year – nothing unusual there.
The first time things start to look worth a paddle is on the morning of Monday, 1st September. Blue Bay sees a clean, gentle offshore breeze from the WNW, with a moderate 3ft swell out of the ENE and a period of 9 seconds. The combined energy of all swells directed here is moderate at 294. Consistency is a bit of a question mark for this spot, so it’s not a guaranteed all-day session, but it’s the best-looking start we get.
The standout, though, is the morning of Wednesday, 3rd September. The water goes glassy, the swell bumps up to 5ft from the ENE with a period of 11 seconds – that’s a proper groundswell. The combined energy here is strong, hitting 466. This is the pick of the whole forecast. The set waves will have some punch, and that glassy surface means the reef will be putting out clean, lined-up waves. The swell direction is right in the sweet spot for Blue Bay, too. This is the one to circle on the calendar.
For the rest of the period, it’s either blown out, onshore, or too small. The morning of Thursday, 4th September, has a clean cross-off breeze and 3ft surf, but it’s a step down from the standout a day earlier.
So, to sum it up: don’t waste your time on the small stuff through late August. Wait for that glassy Wednesday morning early in September – that’s where the magic is.

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.
