The Lowdown

G’day, Rusty here, and I’ve gotta level with you – the outlook for Blue Bay is a pretty quiet one for the next couple of weeks. We’ve got a long stretch of nothing much, so don’t get your hopes up too early.

We start off with a real flat spell. From Friday 21st August right through to Tuesday 25th August, there’s just nothin’ worth paddling out for. Tiny swell, weak energy, and the wind is mostly cross or cross-on, making it messy. You’re looking at a solid five days of poor surf – best to leave the board in the shed.

Things start to stir a little on Wednesday 26th August. The morning shows a weak 3 ft swell from the ENE, with a cross-offshore breeze from the SW. The wave energy is still low (188), but the conditions are clean. It’s only surfable in a very ordinary kind of way. Thursday 27th August morning is a highlight – a glassy 3 ft ENE swell, with the wind dropping to nearly nothing (SSE at 3 mph). The combined energy is still weak (171), but those glassy conditions make it your best bet for a clean, small-wave session. It’s not a standout for size, but for the week, it’s the pick.

Friday 28th August through Monday 31st August is a mixed bag of small, poor-quality waves. The wind stays onshore or cross, and the swell never really gets going. There’s a moment on Monday 31st August morning where a long-period 3 ft S swell (17 second period) rolls in, with a combined energy of 580 – that’s moderate energy. But it’s light cross-on, and the commentary says it’s marginal. For a reef break like Blue Bay, that long period could set up a nice line, but the size is tiny.

The real standouts come in the first week of September. Tuesday 1st September morning is your best bet for the whole outlook. We’ve got a clean 3 ft S swell (11 second period), with a light cross-offshore breeze from the WSW. The combined energy is 286 – moderate – and the commentary says to expect good surf conditions. The swell direction matches the optimum (SSE direction from the guidance), and the offshore wind will keep it clean. For a reef break that’s inconsistent, this is a nice little window. Crowds are possible here sometimes, so you might have some company.

Saturday 5th September morning and afternoon are the other highlights. Morning brings a clean 3 ft S swell (9 second period) with a moderate offshore wind from the W (12 mph). The combined energy is 268. The afternoon sees the swell period jump to 12 seconds, and the energy climbs to 366 – moderate, with good conditions expected again. This is a solid, clean day for the inconsistent reef.

Water temp at Blue Bay is 64°F (anomaly -1°F), so it’s about average for the time of year. Nothing unusual there.

No huge swell here – nothing over 5 ft – so it’s all manageable for intermediates. The best days are Tuesday 1st September and Saturday 5th September. The long-range stuff is promising but less certain. Keep an eye on the forecasts.

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.
