The Lowdown

G’day, Rusty here. Let’s break down what Blue Bay’s got cooking over the next couple of weeks.

It’s a bit of a slow burn, but there are a few clean windows if you know when to go. Water temp is 18° – right around average for this time of year. Nothing unusual there.

First real shot is Thursday morning, September 10th. We’ve got south swell at 8ft, 9-second period, and a cross-offshore breeze. Wave energy is solid (1112), but the call is “marginal” due to tide. This one’s for the experienced only. Thursday arvo is similar at 7ft.

Friday morning the 11th looks much sweeter – 6ft south swell, 10-second period, cross-offshore wind, and combined energy of 707. The word is “expect very good surf conditions.” This is your first standout. Blue Bay is a reef break that’s inconsistent, and crowds are possible. Swell direction (S) is nearly spot on the optimum SSE. Clean, cross-off conditions mean good shape.

Saturday morning the 12th is the real gem for the near-term. Swell drops to 4ft from the south, but the period jumps to 12 seconds – proper long-period groundswell – and it’s glassy. Combined energy 677. Clean, lined-up waves for the intermediate surfer. This is your top pick.

From Saturday arvo through Tuesday the 15th, it fades to tiny – down to 1ft by Tuesday – and winds turn onshore. Those days are a washout.

Wednesday the 16th sees a bump to 6ft from the south, but it’s short-period (8 seconds) and cross-onshore – messy. Thursday the 17th is similar but smaller.

Friday the 18th morning is tiny but glassy – 2ft, 10-second period. Surfable but very ordinary. A longboard might be fun if you’re keen.

Now the big long-range standout: Saturday the 19th morning throws up a massive 13ft south swell with an 11-second period and cross-offshore wind from the WNW. Combined energy is enormous (3610). This is big, powerful groundswell – experts only. At that size, it’s going to be heavy and fast on the reef. It’s 9 days out, so check back in.

Sunday the 20th afternoon delivers a 7ft SSE swell, 11-second period, and glassy conditions – zero wind. Combined energy 883. Clean, solid, and lined-up. Another excellent window for the confident intermediate to expert surfer. Crowds are possible here.

After that, the swell fades and winds go onshore through to the end of the window. A few tiny glassy mornings around the 22nd and 24th, but nothing special.

Best bets: Saturday morning the 12th for clean, glassy, intermediate-friendly waves, and Sunday the 20th afternoon for a bigger, glassy, powerful session. The 13ft pulse on the 19th is a wildcard for experts only.

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.
