The Lowdown
Alright, Rusty here. Let's be honest, the next couple of weeks are going to be a real grind for waves. I've scanned the charts and there's just nothing good on offer for quite a while. We're looking at a long, quiet stretch.
The only spot on the cards is JT Flemming, a point break that, to be honest, rarely breaks and when it does, it's usually for beginners. It's a tough one to call.
The whole first week, from September 12th right through to the 24th, is a write-off. The wind is howling from the ENE at 9 to 19 mph, it's a cross-shore breeze that's just chopping everything up. The swell is all over the place, mostly short-period windswell from the NE and ENE with periods between 5 and 10 seconds, and the combined energy never really gets going, staying weak to moderate at best (267 to 838). Every session is marked as "poor surf conditions" and scores a zero out of ten. It's just not worth paddling out.
There's a tiny glimmer on September 25th. The wind swings to a cross-offshore from the E, dropping to just 6-9 mph, which will clean things up nicely. Swell from the ENE is small, only about 2.6 ft, with a 9-second period and combined energy of 147 to 229 (weak to moderate). The comments even say "surfable waves but very ordinary conditions". It's not great, but for a spot that rarely breaks, you might snag a couple of tiny, clean ones on a longboard. That's your best shot for the whole outlook.
After that, we slide right back into the same pattern of moderate ENE winds and poor surf for the rest of the month. The water temperature is sitting at a pretty normal 80.4°, so at least you won't be cold while you're sitting there waiting for something to happen.

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