The Lowdown
Alright, it’s Rusty here, and I’ve gotta say, it’s a slow start for Blue Bay. We’ve got a dry spell to sit through before things start looking up. The first real weekend and the following week are mostly a washout with small, messy, or onshore conditions, so just park the board for a bit.
The first bit of action worth paddling out for is on Friday morning, August 14th. The wind goes glassy, which is a huge plus, and we’ll see a 4ft swell from the S with a period of 9 seconds. The wave energy is moderate (267), and it’s clean. Not a massive day, but for a dawn patrol, it’s the best we’ve got.
Now, the real standout – the one you clear your calendar for – is the Thursday morning, August 27th session. This is a big one. The swell jumps to 8ft from the S with a period of 10 seconds, pushing very strong wave energy into the reef (1383). The wind is glassy out of the WSW. This is serious, powerful groundswell, and it’s going to be a proper reef-break session. For experienced surfers only at that size – it’s too big for beginners. The water temp is about 64°, which is a touch below average for this time of year, so you’ll want a wetsuit.
Friday morning, August 28th, is still solid as the swell drops back to a still-chunky 6ft from the S with an 11-second period. The wind is cross-off from the SSW, keeping it clean, and the wave energy is strong (827). This is another excellent window, but it’s a step down from the Thursday peak.
Blue Bay is a reef setup, and it’s inconsistent, so don’t camp out waiting for it, but when the swell and wind line up like that Thursday morning, it’s a proper gem. The break is fairly exposed to the S, and the optimum direction is SSE, so that S swell is working well. On the standout days, crowds are possible, so get in early.
Other than those two standout mornings, the rest of the 16-day window is a mix of poor surf, small swells, or onshore winds, with a couple of clean but weak days on the 22nd and 23rd that are just ordinary. The gap from now until August 14th is a few days of nothing, and then again after the 28th, it fades out.
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.
