The Lowdown

G’day, Rusty here. Look, I’ll be straight with you—this 16-day window for Blue Bay is a bit of a mixed bag, with a lot of quiet spells and only a few real highlights. The first surf worth paddling out for doesn’t actually show up until Saturday morning, August 1st, so the week leading up to it is a write-off.

We start with a bit of a pulse on Friday afternoon, July 31st, with a 6 ft south swell, but that 12 mph cross wind and a cross-chop make it a messy one. The wave energy is moderate (668), but it’s not worth your time.

The first real glimmer comes Saturday morning, August 1st. A 5 ft swell from the SSE, with a period of 9 seconds, and a light breeze swinging cross-offshore from the SW. The water’s hovering around 65°F, which is about average for this time of year. The sets should be clean and manageable. The energy’s still moderate (456), but the conditions are right. Then Saturday afternoon gets even better—same 5 ft SSE swell, but the wind goes glassy, absolutely flat calm from the SE. That’s a prime window for a few hours of clean, glassy peaks. Blue Bay is a reef break, so it’s inconsistent, and crowds are possible, but with the right tide, you’ll find some fun ones.

Sunday morning, August 2nd, is a standout. The swell bumps up to 5 ft from the SSE, but the period stretches to 12 seconds—that’s a proper groundswell with real push. The combined energy is strong (875). The wind is a light northerly, creating a slight cross-shore, but the waves will have shape and power. This is a long-period swell, so at a reef break like Blue Bay, it should line up nicely, though it might be a bit too straight for the beachies. For intermediates, it’s a solid day. The afternoon, however, turns into a write-off with a 16 mph cross-on NE wind and choppy conditions—don’t bother.

Monday morning, August 3rd, drops to a 3 ft SE swell (11-second period, groundswell), with a clean cross-off wind from the NNW. The energy is light (286), but it’s clean. A good session for a log or a fun board.

From Tuesday, August 4th, through to Thursday, August 7th, the swell is tiny or messy, with most days offering nothing. There’s a brief reprieve on Thursday morning, August 6th, with a 5 ft south swell, 9-second period, and glassy conditions—clean, but the energy is moderate (433). Still, that’s a morning worth checking.

Friday morning, August 7th, is another gem. A 5 ft south swell, 10-second period, and glassy calm from the SSW. The energy is moderate (472). Clean, fun waves for the experienced intermediate. The afternoon is a no-go with onshore easterly wind.

After that, the second week fades fast. Saturday, August 8th, drops to 3 ft, and by Sunday, August 9th, it’s barely an ankle-snapper at 3 ft. From Monday, August 10th, through to Saturday, August 15th, the swell is tiny—1.0 ft to 3 ft—with periods of strong offshore winds that keep it clean but too small to ride. The energy is weak (20 to 168). A few mornings have a glassy feel, but the waves just aren’t there.

The best of the lot? Saturday morning, August 1st (glassy, clean) and Sunday morning, August 2nd (strong groundswell, 12-second period, moderate energy). The long-range later in the second week is a snooze—don’t hold your breath.

Stay stoked,
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.
