The Lowdown
Right then, let’s have a look at what’s on the cards for this stretch of coast.
Honestly, I gotta be straight with you – this is a tough run for JT Flemming. We’re looking at a long, frustrating gap here. For almost a full week, from Monday afternoon the 10th right through to the end of Saturday the 15th, the conditions are just no good. Persistent, gusty cross-shore winds from the ENE make a mess of things. Swell heights bob around, but with lumpy cross-chop and those moderate to fresh breezes, it’s just a choppy, blown-out mess. You’d be fighting the wind more than the wave. The energy is weak, rarely getting above moderate (mostly seeing values between 100 and 260).
Now, it’s not all doom and gloom. The first real glimmer of hope comes in on Sunday morning, the 16th of August. This is the standout of the entire window. We get a solid offshore breeze from the SSE, which at 19 mph is going to groom the face beautifully. The swell jumps to a serious 16 ft from the ENE with a combined energy rating of 5687 – that’s a lot of power. The period is a long 11 seconds, making it a proper groundswell. This is expert territory, though. For a point break, this kind of long-period energy can be absolutely magic, wrapping in and holding up. The downside? This break is notoriously *rarely breaks*, so we need the stars to align. The winds will clean it up, but the sheer size means it’s for the experienced crew only.
Sunday afternoon drops off a bit to 7 ft with a cross-offshore breeze, still clean but not as punchy. After that, Monday morning the 17th gives us a taste of glassy conditions with a 4 ft swell, but it’s on the small side and the energy is low (214), the kind of day you go for a paddle and hope for a sneaky one.
Beyond that, we slide back into small, weak, cross-shore slop right through to the end of the forecast. The window really closes off again. The water temp is sitting at a warm 80°, which is pretty much bang on average for this time of year.
Overall, if you’re an expert and you can get out early on Sunday the 16th, that’s your one and only shot. For everyone else, this is a two-week period to rest the shoulders and wait for a better forecast.

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.
