The Lowdown
Alright, Rusty here. Let's look at what we've got coming up for the next couple of weeks.
Honestly, it's a long, dry stretch ahead. From Wednesday the 9th, all the way through to almost the end of the month, JT Flemming gets hammered by a constant cross-shore wind. We're talking 20 to 35 km/h from the ENE most days, just turning the ocean into lumpy, cross-chop. There's some swell around, but with that wind, it's a total mess. The water temp is sitting at 27°, which is right about average for this time of year.
You’re looking at a nearly two-week gap here with nothing worth paddling for. The only decent chance we've got shows up on Thursday the 24th of September. The wind finally lets up, dropping to almost nothing – just 5 km/h from the E and ESE, giving us a clean, cross-off breeze. The swell won't be big, about 0.9 to 1.0m from the ENE with a period of 8 seconds, but the combined energy reading (242) means there'll be enough to push a longboard around. It won't be pumping, but after weeks of chop, it'll feel like a treat. This spot rarely breaks, so the fact it's looking clean is actually something to take note of. And it's a beginner-friendly point break, so if the crowds show up (and they can sometimes), just share the waves.
So there it is: a long wait for some clean, knee-to-waist high waves on the 24th. That's your best bet.
Rusty out.

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.
