The Lowdown
Alright, let’s be straight about it. For JT Flemming, the next 16 days are a total bust. From now right through to the 21st of August, every single session is marked as poor surf. There’s no highlight, no hidden gem, just a long stretch of nothing.
The first chance to even look at the water is Thursday the 6th of August. We’ve got a 1.3m swell, but it’s short period, only 5 seconds, coming from the ENE. The wind is a cross-shore from the same ENE direction at 20 km/h, and it’s already lumpy with cross-chop. The combined wave energy is weak, just 97. The water’s 27° with a tiny anomaly of 0.2°, so pretty average for the season. Not that it matters, because it’s a no-go.
This repeats every single day. Friday the 7th, Saturday the 8th, Sunday the 9th – swell hangs between 1.2m and 1.8m, but the period is always short, 5 to 8 seconds. The wind stays 25-30 km/h from the ENE, cross-shore, and the chop gets worse. The energy climbs to 251 on the 9th, but with that wind, it’s just messy.
The second week is worse. From the 14th of August, the swell gets bigger – 1.6m, 1.7m, up to 2.1m by the 17th and 18th. The energy hits 539 on the 18th, which is strong. But the wind is still a cross-shore from the ENE, 25-40 km/h, and the period stays short. It’s a power chop, not a wave you can surf. By the 20th and 21st, there are storms and rain, but the wind doesn’t let up.
The break is a point, but it’s rarely breaking, and with this constant cross-shore wind and short-period, lumpy swell, this setup looks more interesting for kite surfing than paddle surfing. It’s a blank run, and for this area, that’s normal.

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.
