The Lowdown
Alright, let’s talk about JT Flemming in terms you can feel. This is a point break, good for beginners, but it’s one of those spots that’s *rarely breaking*, so you gotta be patient. And the next couple of weeks? Patience is about all you’re gonna have.
The only real chance for a wave happens on Sunday afternoon, August 16th. You’ll see chest-to-head-high waves at about 5ft coming from the ENE. The wind is a tidy cross-off out of the SE, so the surface is clean. The water’s a warm 80°, which is normal for this time of year. It’s the only time the forecast says "expect good surf conditions." But don’t forget, this break is inconsistent, so it’s not a guarantee.
Then, get ready for a drought. From Monday morning, August 17th, through the end of Sunday, August 31st, it’s basically flat or messy. We get a lot of 2ft to 5ft dribble with short, choppy periods of 4 to 7 seconds. The wind is cross-shore, and the water’s all lumpy. The energy numbers are mostly in the low to moderate range – nothing that’s going to peel cleanly.
There is a late spike on Friday, August 28th. By Friday afternoon, the swell jumps to 8ft with a 12-second period – that’s real groundswell energy, with the combined energy reading at 1630. That’s strong. But that size is well over 8ft, so this is big-wave territory for experts only. And the wind is still a stiff cross-breeze from the ENE at about 20 mph, so the waves are going to be lumpy. It’s only rated as "marginal surf forecast or questionable tide conditions," so it’s a maybe, not a go.
For the kite-surfers? The wind from the 17th onward will be steady cross-shore, so the open exposure might be fun. For a paddle surfer, the Sunday the 16th is your best – and pretty much your only – play in this 16-day window.
This is Rusty. Keep it salty.

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.
