The Lowdown
Alright, Rusty here with the rundown on Blue Bay. Let’s call a spade a spade – it’s looking lean for a while. This joint can be a bit inconsistent, and for the next week you’ll be fighting for a crumb.
From now until August 22nd, it’s mostly poor surf. We get a little 3ft SSE swell on the morning of the 19th with glassy conditions, but it’s barely enough to paddle for. Friday the 21st and Saturday the 22nd mornings have clean, light wind but the swell is tiny, around 3ft.
Hold onto your board for Sunday the 23rd. That morning is the one. A solid 10ft south swell with a 9-second period, and the wind is glassy. Dead flat calm. That’s pushing 1,447 on the energy scale. If you’re an experienced surfer, that’s your window. Beginners – stay on the beach. That’s heavy water. The wind goes onshore in the afternoon, so make the dawn patrol.
After that, there’s a couple more chances. The morning of Monday the 24th and Tuesday the 25th have clean conditions with 5ft and 6ft south swells. Then, Wednesday the 26th is interesting: a strong offshore west wind at 35 km/h cleaning up a 5ft south swell with a long 12-second period. That’s prime groundswell for a reef, but it’s a very long period which can make the reef sections a bit shifty. That’s expert territory.
The big one is the morning of August 23rd. That glassy, 10ft south swell is the best on offer. August 26th is also worth a very early look for the offshore crew. Water temps are about average for this time of year.
Rusty, out.

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.
