The Lowdown
Alright, folks, Rusty here. Let’s break down what’s happening at Blue Bay for the next couple of weeks.
The first few days are a total washout. Friday, September 4th and Saturday, September 5th have onshore and cross-shore winds that ruin any chance of a clean wave. Water temp is 19°, which is normal for the season, so a spring suit is fine.
Sunday, September 6th is tiny and weak – not worth paddling out. The energy is barely there (32–142), with short, choppy periods.
Monday, September 7th morning is the first real window. We’ve got a clean 1.7m S swell with a 9-second period, and a light offshore wind from the WSW. The combined energy is 431 (moderate), and conditions are clean. The afternoon gets onshore, so hit it early.
Tuesday, September 8th brings a big jump in size – 2.5m of SSE swell. The morning is cross-off and clean, but at that size, it’s expert-only. The combined energy is massive (1027). The afternoon is onshore and messy. Not for the faint of heart.
Wednesday, September 9th morning is the absolute standout. Glassy conditions, 1.6m SSE swell with a 10-second period, and combined energy of 461. That’s a clean, fun-sized wave. The afternoon gets cross-shore and lumpy, so make the most of the early.
Thursday, September 10th and Friday, September 11th have 2–2.5m S/SSE swell, but the wind is cross or cross-on, making it lumpy and choppy. The energy is over 1000, but it’s more kite-surfing territory than paddle.
Saturday, September 12th and Sunday, September 13th drop to 1–1.5m, but the wind stays onshore and messy. The period is short (7–9 seconds), so the waves are weak and choppy.
Monday, September 14th and Tuesday, September 15th have 2–1.9m swell with some clean morning windows, but the wind is still cross-off or cross. The energy is moderate (393–705), but consistency is sketchy.
From Wednesday, September 16th onward, the swell fades fast. By Friday, September 18th and Saturday, September 19th, we’re down to 0.4–0.6m – barely a ripple. The winds are cross-off or cross-on, but there’s no power left (48–119). The run is done.
So, the one to circle is Wednesday morning, September 9th at Blue Bay. Glassy, clean, 1.6m SSE swell, and moderate energy. The other decent window is Monday morning, September 7th, with clean offshore winds and 1.7m S swell. The rest is either too big and messy, or too small to bother.
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.
