The Lowdown

Alright folks, Rusty here. Let's break down the next couple of weeks for Blue Bay.

First up, the water temp is about 65°F, which is pretty normal for the season, so no surprises there.

The week kicks off with a real gem. Monday the 7th of September, we’ve got a clean, glassy morning with a 5ft S swell rolling in. The energy is moderate (304), and it’s looking like good surf conditions. That’s the standout of the whole run, no doubt. The wind is dead calm, making for a beautiful morning session. The afternoon turns onshore and it’s game over, so get out there early.

Tuesday the 8th, the swell jumps to 8ft, but the wind is a messy cross-shore, making it a write-off. That’s expert-level size with poor conditions. Wednesday the 9th sees a drop to 4ft, with a cleaner cross-offshore breeze, but it’s ordinary. The sea breeze on Wednesday afternoon is a strong 28 mph, so that’s a no-go.

Thursday the 10th and Friday the 11th are interesting. The swell is solid, around 8ft to 10ft, and the mornings are clean with a cross-offshore wind. The energy is strong (over 1300 on Thursday morning). The period is around 10 seconds, which is decent. But for a reef break that’s inconsistent, it’s only for the experienced crew. Thursday morning (10th) is another potential highlight, but with the 10ft S swell, this is only for the experts. The crowd factor is ‘sometimes’, so you might have it to yourself.

From Saturday the 12th, the swell starts to drop, and the wind becomes more onshore or cross-onshore, leading to poor conditions through the middle of the month. There’s a real gap from the 13th to the 15th where there’s almost nothing doable.

There’s a pulse around Wednesday the 16th of September, with an 8ft S swell and light cross-onshore winds. The energy is strong (1341), but the wind is just enough to spoil it, so it’s marginal.

The rest of the outlook into the third week is small and wind-affected. The best bet is definitely Monday morning, September 7th. That’s your window. The Thursday morning the 10th is a close second for the big-wave crew.

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.
