The Lowdown
Alright, let’s break down what’s happening at Blue Bay. For the first week and a half, from the 12th up to the 23rd of September, you’re looking at a whole lot of nothing. Small, onshore, choppy—the whole package.
The water temperature is 64°F, which is normal for the season.
Now, the only time it gets interesting is around Wednesday the 16th and Thursday the 17th. A big S swell hits, pushing 10ft to 13ft, with combined energy readings (1672 to 2735). That's serious power. The wind is SSW at 22 to 25 mph, blowing cross-offshore. The face will be clean, but that much size—over 8ft—makes it a spot for experts only. Beginners, stay on the beach.
The swell period is around 9-10 seconds, so it’s a decent push but not a long-period groundswell. On a reef like Blue Bay, you’ll get some steep, heavy walls. Getting out will be a mission.
If you want something mellow, Saturday the 19th of September is your day. Swell drops to 2ft, but the wind goes dead calm from the NW in the morning—total glass. The energy is lower (615), but you’ll get clean, tiny waves that are perfect for a longboard. No crowds to worry about, either.
The rest of the second week is flat and messy. The 26th and 27th have a couple of glassy mornings, but with swell barely over 2ft from the ENE, it’s not worth getting wet for unless you’re desperate. For the big, windy days, you might see some kite surfers having a go, but for a paddle surfer, it’s a waiting game. That mid-week pulse is the only real action, followed by that glassy Saturday.
Rusty.

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.
