The Lowdown

G'day, this is Rusty. Look, I'm gonna level with you straight up—for the next week and a half, Blue Bay is dead quiet. We're talking tiny, weak swells, mostly under 3 feet, and the conditions are pretty ordinary. The water temp is sitting at about 64°, which is a touch cooler than usual for this time of year, but nothing too crazy.

From Thursday the 20th right through to Saturday the 30th of August, it's a real struggle. There's barely any energy in the water (combined swell energy is mostly under 200, often below 100), and the waves are just not worth paddling out for. You'll see a few glassy mornings, like Saturday the 22nd and Sunday the 23rd, but the swell is tiny—only 1 feet to 2 feet—and short period, so it's just not gonna hold you up. There's a brief window on Monday the 24th afternoon where the swell picks up a little to 2 feet from the south with a 10-second period (combined energy of 123), and the wind goes light cross-off, making it clean. It's surfable, but honestly, it's very ordinary.

Then on Sunday the 30th of August, things finally start to change. The morning session sees a jump to 6 feet from the ENE (combined energy of 362), with clean conditions thanks to a light cross-off north wind. It's a bit messy by the afternoon though, as the wind swings onshore. That's the first real glimpse of hope, but it's still not the standout.

The real standout comes on Tuesday the 1st of September. Morning at Blue Bay has 8 feet of east swell rolling in, with a 10-second period (combined energy of 1382), and a clean offshore breeze from the WNW. That's quality groundswell for experienced surfers. The water's still around 64°, but with that much energy and clean conditions, it's the best on offer across the whole forecast. Just be aware, at 8 feet, this is only for the crew who know what they're doing. The afternoon sees the wind shift onshore and mess things up a bit.

Wednesday the 2nd of September morning still has solid 7 feet east swell (combined energy of 771) with a moderate cross-off breeze, keeping it clean. Not as punchy as Tuesday, but still a decent session. After that, the swell drops off heading into the 4th of September, with a smaller 5 feet south swell and glassy conditions on Friday morning—worth a look if you've got a longer board.

So to wrap it up, the first week and a half is a write-off. The real action is from the 30th of August through to the 2nd of September, with Tuesday the 1st being the absolute standout. Keep an eye on the forecast, 'cause this sort of window can shift a bit, but right now, that's your best bet.

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.
