The Lowdown

Alright, this is Rusty here, and I’ve been staring at the charts for Blue Bay. It’s a mixed bag, but there’s a moment in there that’s got my heart racing a little.

We’re starting off pretty quiet. The first few days are just small, weak ripples. The water temp is sitting right on 65°, which is spot on for this time of year, so nothing weird going on there.

The first real glimmer of hope comes on Friday, September 4th. That morning, the stars are set to align. We’ve got a clean 5ft swell rolling in from the south, with a solid 11-second period – that’s proper groundswell energy. The wind is a total glass-off, from the SSE. For a reef break like Blue Bay, that’s about as good as it gets. The combined energy is moderate (521), but the quality is what matters. This is the standout window. Keep in mind, though, this spot is inconsistent, so you have to be ready to jump when it’s on.

The rest of the first week is a bit of a write-off. The wind is all over the place, mostly onshore or cross-shore, and the swell is either too small or too short-period. Saturday and Sunday look sloppy.

Now, looking further out, there’s a big pulse of energy forecast for Thursday, September 10th and Friday, September 11th. Thursday afternoon sees a heavy 8ft south swell with a 10-second period. The combined energy is massive (2889), but the wind is cross-shore, so it’s going to be a messy, powerful beast. That’s expert-only territory, and honestly, for a reef, it might be more of a chaotic mess than a dream.

The real long-range promise lands on Friday morning, September 11th. That’s a 7ft south swell with a very long 12-second period. The combined energy is strong (1172), and we’ve got a light, clean cross-offshore breeze from the SW. That’s the second standout. It’s a week and a half away, so don’t carve it in stone, but it has the potential to be the best session of the entire forecast. The longer period means better shape, but at a reef, it’ll be lining up nicely.

The following week drops off significantly. The swell sticks around but gets smaller, and the wind never really cooperates. There’s a funny little pulse on the 17th with a 6ft SE swell, but the period is a weak 6 seconds, so it’ll be a windswell mess. Not worth the paddle.

So, if you’re looking for a clean, glassy, rippable wave, be on it first thing Friday morning, September 4th. For the bigger, more powerful stuff, keep an eye on Friday the 11th. Everything else is just filling in the gaps.

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.
