The Lowdown
Alright, let’s have a look at the outlook for Blue Bay. To be honest, the next couple of weeks are a bit of a struggle. We’ve got a long, quiet stretch ahead before anything really worth paddling out for shows up.
Right now and for the next several days, the surf is pretty ordinary. We’ve got some small swell, around 3 feet to 4 feet, coming from the ESE, but the periods are short, around 7 to 10 seconds, meaning it’s weak and lacking punch. The combined swell energy is moderate at best, sitting around (209-260) on Monday and Tuesday this week. Winds are mostly onshore or cross-onshore, and the conditions are poor. Not much to get excited about.
We do get a little window on the morning of Wednesday the 19th, with a clean, glassy morning. Swell is small, only 3 feet from the ESE, but that 10-second period gives it a bit more shape. It’s surfable but very ordinary. The water temp is 63°, which is about 1° cooler than average for the time of year – nothing too out of the ordinary.
Then we hit a gap. From Thursday the 20th through to Tuesday the 24th, it’s mostly tiny surf – 1 foot to 3 feet – with weak energy (19-177). A few mornings are glassy or clean, but there’s just no size to work with.
The next real standout doesn’t come until Thursday the 27th. The morning sees a solid 6 foot swell from the NE, with a 7-second period, and combined energy cranking up to (565). Winds are offshore from the SSW at 15 km/h, which means clean, lined-up conditions. This is the best bet across the whole forecast. The 6 foot height is fine for intermediates, and the offshore breeze should keep it smooth. It’s a reef break that’s inconsistent, so you’ll want to be patient for the sets, but when they come, it’ll be worth the wait. Expect it to get a bit busy – crowds are possible there.
After that, the end of the month looks messy. Sunday the 30th morning shows a bigger 7 foot swell from the S, 10-second period, and very strong energy (813). But conditions are marginal, with light cross-shore winds, so it’s more of a challenging day for experts only. After that, the first day of September is tiny again.
If you’re looking for the best session, Thursday the 27th morning is the one to pencil in – clean, solid chest-to-head-high waves from the NE, with that offshore wind making it glassy. The rest of the window is either too small or too wonky.

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.
