The Lowdown
Alright folks, Rusty here. Let’s have a look at what Blue Bay has got cooking for us over the next couple of weeks. I’ll be straight with you – it’s a lean start, and we’re going to be waiting a while for anything decent.
The first real glimmer of surfable waves doesn't show up until Monday the 24th, and even then it’s just ordinary. The week leading up to that is a write-off: tiny, weak swells with cross-onshore winds chopping everything up. The combined wave energy is struggling to get past 100, just weak and messy. A few mornings have clean conditions, but with swell heights barely reaching 2 ft, there’s nothing to ride.
From the 25th, we see a bit more push. The swell picks up to 4 ft to 4 ft on Tuesday the 25th, coming from the ENE with a period around 7 to 8 seconds. The winds are light and cross-offshore, so the surf is clean. The combined energy hits 194, which is a solid step up – moderate energy. It’s still not a standout, but it’s surfable. The water temperature is sitting at 64°F, which is about 1°F cooler than average for this time of year – nothing wild, just a touch on the cool side.
The real standout, and the one worth circling on your calendar, is looking like Tuesday the 1st of September. We’ve got a big SSW groundswell pushing in with a combined energy of 12,531 – that’s strong to very strong. The swell height is 15 ft, coming from the SSE with a long period of 13 seconds. This is proper, powerful groundswell. Now, the rub is the wind – it’s a cross-onshore at 12 mph, so it’ll be a bit lumpy. But for experienced surfers, the sheer size and energy will be there. This is not for beginners; 15 ft is big, expert-only territory. The water temp anomaly is not given, but the surf is going to be raw and heavy. If you’re a confident charger, this is the day to be at Blue Bay. The swell direction from the SSE is bang on the optimum for the spot, which is a good sign for the wave shape, though that long period might make it a bit straight at this beach setup.
Keep an eye on Wednesday the 2nd as well. The swell is still big at 12 ft from the SSE, with a 12-second period. The wind shifts to a light cross-shore from the NNE, which would clean it up nicely. The combined energy is still a massive 3,032, so there’s plenty of power. It’s a close second to the Tuesday, but the cleaner wind might make it the better session for those who can handle the size.
Once we get into the first week of September, the surf drops off again, with smaller, less energetic swells and cross-onshore winds returning. The second week is a mixed bag, with some size but questionable conditions.
So, if you’re keen, hold out for the end of the month. The 1st of September is the big one, but it’s for the brave. The days before that are just small, clean scraps. The best bet for a clean, fun wave is the 25th, with the smaller swell and light winds.
Stay stoked, and see you in the water.

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.
