The Lowdown

Alright, folks, Rusty here. Let’s take a look at what we’ve got coming up.

Looks like the surf is going to be pretty ordinary for the next couple of weeks. There’s a real lack of quality on offer, a lot of short-period, wind-blown slop with hardly any clean windows. The first stretch of the period is looking like a write-off, with onshore and cross-shore winds messing up whatever small combo swell is running. We’re looking at a few days of poor conditions before things maybe get a little more interesting.

Right, the opening few days are a wash-out. Sunday the 16th has some real energy, with a solid 10ft of 9-second wind swell, but the wind is on it from the ESE at 22 mph, and with rain and a t-storm risk, it’s just a mess. Surf quality is poor. By Monday the 17th, the wind swings cross-shore and the swell drops to 5ft. It’s still lumpy and poor. Tuesday and Wednesday, the swell backs right off; there are some longer-period south swell lines underneath, with periods up to 18 seconds, but they're just not wrapping in with any power. It’s tiny, cross-windy and barely breaking.

We won’t get any real surf until maybe Friday the 21st or so, but that's just a little 3ft of 7 seconds. This is rough stuff, we’re looking at a few days with basically nothing rideable.

As we roll through the next week, we see some longer-period southwest energy trying to show, but it's still small and the cross-shore winds hold it back. It’s a week of small waves, just not worth paddling out for.

The most promising stretch might be around the 29th and 30th. We have some more solid ENE swell building, reaching 10ft with the wind, but, there’s the downside. It’s short-period, 8-9 seconds, and the easterly winds just won't ease up. The cross-shore breeze is going to keep it lumpy and messy, and a lot of that power is going to get blown out. The break, Middles/Generals, is fairly consistent, but when the wind is pumping from that angle, it’s going to be rough and cross-chop city. It’s an exposed spot, and with that strong cross-shore breeze from ENE at 25 mph, it’s going to be pretty wild and hard to manage.

The conditions look more interesting for a kite surfer than someone on a paddle board for the end of the period, if you ask me.

Honestly, I don’t see a single standout day in this entire run. The swell is there at times, but the winds just keep ruining it. This is a case of watching from the beach and catching up on your board repairs. It might not stay bad forever, but this run is not looking good.

Stay tuned, and I’ll keep an eye on it for you.

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.
