The Lowdown
Righto, Rusty here. Let's have a look at what's on offer for us at JT Flemming.
To be straight with you, the next week and a half is pretty grim. We're looking at a long stretch of surf that's just not worth paddling out for from the start of the period right through to the 16th of August. The wind is mostly a fresh cross-shore from the ENE, pumping at 15 to 22 mph, and that is just messing everything up. The combined swell energy is weak to moderate at best, with values like 204 and 219, but it's all wind-affected junk with a short period, so it's all poor surf conditions.
Now, there is one standout that pops up after that dry spell. Mark your calendars for Monday the 17th of August. For the morning session, JT Flemming, a point break, will switch on. The swell will be a clean 5 ft from the NE with a groundswell period of 11 seconds, pushing a combined energy of 572. That's our only real window. The wind will be light from the SSE at 9 mph, shifting offshore, which will give us a gentle offshore breeze and clean faces. The water temperature is neutral for the time of year.
That Monday afternoon session on the 17th is also worth a mention. Swell drops to 4 ft from the NE with a 10-second period, but the wind will be a light 6 mph from the ESE, making it a light breeze with clean conditions.
The rest of the window after that drops off fast, with the wind swinging back onshore or cross-shore and the swell fading into nothing.
For the groms or beginners out there, the Monday morning swell at 5 ft is manageable, but don't expect a party wave. The break is inconsistent; it rarely breaks, so the fact it's showing any life is pretty notable. And when it does break, you might have to share it with a few others, as crowds are known there sometimes.
So, if you're free on that Monday, the 17th, that's your one shot. The rest looks like a write-off for paddle surfing. With all that cross-shore wind and moderate wave energy, it would be more interesting for the kite crew.
Rusty.

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.
