The Lowdown
Alright, Rusty here.
Alright, let's look at Blue Bay. It's a reef break, and we're in for a real mixed bag over the next 16 days. There are some decent windows, but a lot of waiting in between. The water temp is sitting at 64°, which is about average for this time of year, so no surprises there.
The first real action kicks off this Saturday morning, the 12th of September. We've got a clean 4ft south swell, pushing in with a solid 12-second period. The wind is glassy out of the east at just 3 mph – that's perfect. The combined energy is a solid moderate (630) and the conditions are expected to be good. This is the standout session of the first few days; get on it early because the afternoon gets ruined when the wind swings ENE and picks up to 12 mph, turning it cross-on and choppy. Sunday and Monday are write-offs with cross-on winds.
Now, there's a long gap with nothing good after that morning session. Then things get interesting but tricky later in the week. On Wednesday the 16th of September, a big, serious south swell arrives. We're looking at 12ft to 13ft of swell with a moderate energy reading (1956 to 2968). The wind is cross-offshore, which keeps it clean, but these waves are not for the faint of heart. At over 8ft, this is strictly for experts. The period is a middling 9 to 10 seconds, so it's not a super clean groundswell, but there will be some big, powerful lines. Thursday the 17th is similar, with a still-oversized 10ft to 8ft south swell and clean cross-off winds, albeit with some rain showers.
After that big pulse drops, the surf gets messy and small again through the end of the week. The next real glimmer is the following Saturday morning, the 19th of September. It’s a smaller day, with 4ft of ESE swell, but the period stretches out to a decent 11 seconds. The wind is dead glassy again, making for clean conditions with moderate energy (444). This is the second worthwhile window, but it's much smaller than the mid-week swell. The rest of the second week looks mostly small, weak, and onshore, so that Saturday morning might be your last best chance.
Overall, the standout is hands-down the Saturday morning the 12th: a clean, glassy 4ft south swell. The bonus round for experts only is the Wednesday/Thursday big south swell.
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.
