The Lowdown
Alright, this is Rusty, and I’m looking at the charts for our little patch of coast. Straight up, I gotta be honest with you – this 16-day stretch is a tough one. We’re looking at a long, dry spell with nothing but poor surf conditions for days on end. The only break that showed up in the forecast is Middles/Generals, and it’s a pretty bleak picture.
The overall pattern is dominated by messy, cross-shore winds – mainly from the ENE and NE – that are just chewing up the surface. The water temp is sitting at 81°F, which is pretty much normal for this time of year, so the ocean isn’t doing anything weird. The first real action doesn't even come until Saturday the 19th of September, and even then it’s a marginal call. We’ve got a solid eight or nine days of nothing good before that.
For the first week, from Saturday the 12th right through to Friday the 18th of September, it’s all 'poor surf conditions' with scores of 0. The swell is all over the shop – from tiny 1ft to a bigger 7ft, but it doesn’t matter because the wind is consistently cross or cross-on, blowing at 12–25 mph, making everything a choppy, lumpy mess. The energy is moderate at best, with figures like 202 early on, jumping to 1277 by Friday the 18th, but the wind just kills it.
Then, on Saturday the 19th of September, we get a little glimmer. This is the only window that’s even worth mentioning. The swell drops to 3ft, coming from the SSW with a long 16-second period – that’s proper groundswell energy. The wave energy is still strong at 844. The morning has some clouds and a light breeze from the east at 6 mph. It’s cross-on, so not perfect, but it’s the cleanest we’re going to see. It’s rated as 'marginal' with a score of 2. For a spot that is fairly consistent, this is a real letdown. The crowds here are often, so you won't be alone.
After that brief window, it goes straight back into the doldrums. Sunday the 20th through to Sunday the 27th of September is just more of the same: poor conditions, fresh cross-shore winds, and swell that’s either too big and messy or too small and weak. The energy stays strong, hitting 1277 again on the 18th and staying in the hundreds and thousands, but with winds never letting up, it's just not for us. For a break exposed to the east like Middles/Generals, this setup is better suited for kite surfing than paddle surfing.
So, the pick of a very bad bunch is Saturday the 19th of September, early. Don’t get your hopes up, but it’s the only time you might get a half-decent wave.
Stay patient,
Rusty.

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.
