The Lowdown
Alright folks, Rusty here. Let’s take a look at the local stretch for the next couple of weeks.
First up, water temps are sitting around 80°F right now, which is pretty much average for this time of year. No surprises there.
To be honest, the outlook for JT Flemming is a bit of a tough one. The first week and a half is pretty much a write-off. From Wednesday the 19th right through to the end of August, it’s all poor surf conditions. You’ve got a persistent ENE cross-shore wind, usually 12 to 25 mph, and the wave energy is either weak or just building into a messy lumpy chop. Swell heights bounce around from 0.7 ft to 7 ft, but the periods are short, mostly 5 to 8 seconds, so it’s just wind slop. Not worth paddling out for. That stretch runs about 12 days of nothing worth getting excited about.
Then, finally, things start to change around the 1st of September. On Tuesday the 1st, the swell picks up to 7 ft from the ENE with a longer period of 11 seconds, and the combined energy is strong. The winds are still cross, though.
The real standout window, the one to circle on the calendar, is Wednesday the 2nd of September. That morning, the wind drops to absolute glass – 0 mph from the WSW. The swell is a solid 7 ft from the ENE, with a 9-second period, and the combined energy is strong. The report says “expect good surf conditions.” That’s the morning to be out there. The afternoon stays clean with a gentle offshore breeze from the SE, still 7 ft.
Thursday the 3rd starts with a cleaner cross-off wind and 6 ft swell, but it gets a bit lumpy again by the afternoon. So the best of it is really that Wednesday morning, the 2nd of September. It’s a point break, rarely breaks, so when it lines up like this, it’s a special opportunity. Be aware, crowds are sometimes a thing here, so you might have some company.
For the rest of the second week, the swell stays in the 6 ft to 7 ft range with moderate energy, but the winds are mostly cross or cross-on again. Not a total loss, but Wednesday is the pick.
Stay stoked, check the charts, and I’ll see you in the water.

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.
