The Lowdown

G’day, I’m Rusty. Let’s have a look at what’s coming up for Middles/Generals.

Right off the bat, we’ve got a pretty grim run ahead. The forecast kicks off but there’s barely a wave worth paddling for until the very end of the period. From Friday 21 August right through to the start of September, it’s a long stretch of poor surf conditions. The wind is mostly a fresh cross-shore or cross-on from the ENE, and the swell is weak and short period, under 8 seconds, with combined energy readings mostly under 500 (moderate energy at best, but the shape is just messy). The water temperature is about 80°F, which is average for this time of year. For the first week and a half, you’re looking at lumpy, cross-chop conditions with small, weak waves – not worth suiting up.

Then, around Monday 31 August, things get interesting – but only for the experienced crew. A solid ENE swell pushes in, with heights up to 10ft to 12ft and combined energy a massive 2133 to 2779 (strong to very strong energy). The wind stays cross-shore and fresh, but the swell is too big for this break, so only experts should even think about it. The period is 10 to 11 seconds, so it’s a decent groundswell, but it’s going to be a beast. That’s the standout – if you’re confident and hungry, that Monday is your shot.

The rest of the first week of September is still pretty average – cross-onshore winds, moderate energy, and swell around 5ft to 7ft, but the quality is poor. The last day in the forecast, Saturday 5 September, shows a slight improvement with a light breeze and a little more period (11 to 12 seconds), but it’s only marginal with combined energy around 677 to 745 (moderate). Still not great.

Overall, the only real standout in this 16-day window is that big swell on Monday 31 August – but it’s not for the faint-hearted. The rest is a write-off. Stay patient, and maybe save your energy for that one big day.

Rusty.

A general guide to surfing at Middles/Generals can be found by selecting the local surf guide option on the grey menu.

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 Middles/Generals 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.
