The Lowdown
Alright, this is Rusty. Let's be straight with you – the next 16 days are looking pretty grim for most of us. There’s a real dry spell on the cards, with a lot of time where the paddle-out just isn't worth it. We’re talking long stretches of nothing.
The first real glimmer of hope comes on Tuesday, September 8th at JT Flemming. This is a point break, and it’s a rare one – it rarely breaks, so when it does, you pay attention. It’s a beginner-friendly spot, but the crowds are sometimes here, so be ready for that. The water temp is sitting at 80°, which is pretty average for this time of year, so no surprises there.
Tuesday morning we’ll see a 5 ft swell from the ENE, with a moderate offshore wind out of the south at 16 mph. The wave energy is moderate (578). The combo of that clean offshore wind and a decent swell should make for some fun, clean waves. The afternoon is the real standout though. The wind drops to a light 6 mph from the SSE, staying offshore, and the swell shifts to 5 ft from the WSW. The energy picks up to a moderate 775, and the forecast says "very good surf conditions." That Tuesday afternoon is the one session to lock in.
After that, it’s a long, dry road. From Wednesday, September 9th all the way through to the end of the window on September 21st, the forecast is a mess of poor surf conditions. We’ve got a solid 13-day stretch where the wind is mostly cross-shore or cross-on, and the swell is small and weak. The energy values drop right down, with many days barely registering 100 or 200. The swell periods are short, often under 8 seconds, and the heights mostly sit under 5 ft. There’s nothing to get excited about.
The very end of the forecast, on Sunday, September 20th and Monday, September 21st, shows a bit of a cleaner look with some cross-offshore winds, but the swell is still tiny (4 ft) and short-period. It’s not going to be worth the drive.
So, to sum it up: your only real shot is Tuesday, September 8th, and specifically the afternoon session at JT Flemming. Everything else is a write-off. It’s a rare break, and it’s going to be a rare day of surf. Make the most of it.
Rusty.

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.
