The Lowdown
Alright, Rusty here, let's have a look at what’s coming our way.
We’ve only got one spot lighting up, and it’s a bit of a heavy-hitter. The outlook kicks off Tuesday, August 18th, but don’t get your hopes up for a paddle that day. We’ve got a solid 13ft WSW groundswell with a 17-second period, and that’s pumping some serious energy (8159) into the water. The water temp is sitting at 68°, pretty much normal for this time of year. Problem is, that swell is way too big for this spot for anyone but the absolute lunatics. The wind is glassy in the morning, which would be heaven, but again, it's just too much.
Wednesday the 19th and Thursday the 20th are a write-off for quality. We’ve got cross-shore and onshore winds mushing up a still-oversized swell. The energy is dropping from 4760 down to 3415 but the wind is just ruining any chance of a clean face.
Now, Friday morning, August 21st, is where it gets interesting for the experienced crew. The swell has dropped to 8ft from the WSW, still packing a long 15-second period, with a cross-offshore breeze. That’s clean surf. The combined energy (2658) is moderate but the conditions are good for a session. This is the best early call, but it’s not for beginners – anything over 8ft gets hairy, and this is right on that edge.
Saturday and Sunday are a mess with strong onshores and lumpy conditions. The swell drops but the wind stays nasty. Nothing to see there.
Monday morning the 24th offers another window for the experienced. A clean 6ft WSW swell (1654) with a light cross-offshore breeze. Good shape, less grunt. This is your second best bet. After that, the wind turns onshore and it’s game over until we look at the long-range.
The rest of the week into the next is a mix of onshore slop or marginal cross-shore chop. The swell pulses a bit but the wind just won't play ball.
Then we get a bit of a flicker. On Monday, August 31st, there’s a 8ft swell (3714 energy) with a cross-offshore wind in the morning, but the guidance says it’s marginal. It could clean up, but it’s not a lock.
Finally, the real standout of the whole forecast is Tuesday morning, September 1st. We’ve got offshore wind – clean, offshore wind – blowing from the ENE at 16 mph, on a 6ft WSW groundswell with a 16-second period (2082 energy). That’s a recipe for some seriously clean, lined-up waves. This is the one to circle on your calendar, but remember it’s over a week away, so keep an eye on it. The afternoon gets messy again with a way too big 12ft swell coming through.
So, bottom line: For most of us, this is a waiting game. The best, most reliable call for a decent paddle is that Tuesday, September 1st morning session, with that offshore wind. If you’re experienced and hungry, the Friday the 21st morning and Monday the 24th morning are your best earlier shots.
Rusty.

Information about the Blue Holes Surf forecast
The above surf forecast table for Blue Holes provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Blue Holes can be found by selecting the local surf guide option on the grey menu. Our Blue Holes 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 Holes) 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 Holes 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.
