The Lowdown

Alright, let's get real with this forecast for Blue Bay. It's a bit of a rough stretch ahead, so brace yourselves.

The next few days are a total write-off. Tiny, weak swells and onshore winds mean you won't even want to get your board wet. We're just waiting for something to happen.

Then, around the 16th of September, the ocean switches on. A proper-sized, long-period south swell builds in fast, but it's a bit of a monster. The waves will be big, but with a strong south-southwest wind, the bay is going to be messy, lumpy, and hard to ride. We're talking 3-4m of raw, powerful swell. This is only for the experienced rippers out there; the kind of surf that can hold you under. The energy is all there, but the quality is all wrong. You should see the reading on the energy scale, it was way up there, but we're not calling it.

That big pulse eases off a touch over the next couple of days, but it stays big through the 18th, still with a bumpy, onshore wind. There's still plenty of size, but it's going to be tough, challenging conditions.

Then the ocean just backs right off. We get a small window on the 19th with light offshore winds and a clean but tiny 0.6m wave. It's the cleanest it will be all forecast, but you'll be on your shortboard or a fish. The window is short-lived anyway, as the onshore winds return in the afternoon.

The ocean goes quiet again, and we enter a dead patch until the 21st when another big pulse of south swell fills in. We've got another big, powerful swell, 4.0m, but it's coming with a cross-shore wind, which will make it choppy and hard to manage. After that, it’s pretty weak and tiny again.

So, there's a clear winner here: the 19th. It's going to be tiny on Saturday the 19th, but it will be your only shot at a clean, glassy wave. The rest of the period is either too big and messy or too small to care. We get a couple of "ordinary" days around the 24th, but nothing to get excited about.

All in all, this is a forgettable forecast. We're looking at some big, angry swells followed by nothing. For the novice surfer, those big swells are a definite no-go. It’s days like this that you check the horizon constantly, hoping for a shift in the wind. But for now, it's gonna be a frustrating time in the water.

Keep your head up, and let's hope for better conditions soon.

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.
