The Lowdown

Alright, let’s get real. It’s a grim stretch for surf. We’re looking at a solid week and a half of junk. That ENE wind is just gonna be blowing straight across everything, keeping the surface all lumpy and chopped. There's swell, sure, but it's either short-period wind slop or long-period stuff coming from the wrong angle. It’s a mess.

That first Saturday the 15th has some size at 12ft, but it's with 55 km/h cross-shore wind and storm risk. That’s not a surf session, that’s a fight for your life. The wave energy is strong at 2302, but it’s useless energy. You'd be crazy to go out.

Even when it drops to the 3-5ft range next week, the wind stays on it. It’s just choppy, cross-shore junk. There’s a hint of cleaner, longer-period swell on Monday the 17th, but it’s coming from the south, which is all wrong for this place, and it’s only 3ft of it. It’s just a tease.

The one good-looking window is around Thursday the 27th. We finally get some proper groundswell on the charts, with 5ft of east swell at 18 seconds. The energy is still significant, over 2000. This is a week away, so we're just hoping, but this is the one with potential. The wind is still cross-shore, so it'll be bumpy, but at least the waves will have some push. The long period is better for a point break, not for this exposed beach, so it might just close out. Still, it’s the only "maybe" on the board.

That whole stretch from Thursday the 27th to Saturday the 29th looks like our best bet, with 5ft of E swell and periods from 15-18 seconds. But the wind is still going to be messing it up. Then on Sunday the 30th, the size jumps to 8-10ft, but the period drops and the wind is back on it hard. That’s just going to be a huge, bumpy, closed-out nightmare. It's everything you want in size and nothing you want in quality. For the next few days, you’re better off finding something else to do. Maybe get the kite out.

Rusty, signing off.

Information about the Middles/Generals Surf forecast

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