The Lowdown
Alright, it’s Rusty again. Let’s break it down in feet and miles per hour.
It’s a rough start at JT Flemming, a point break that’s pretty inconsistent. The first week is mostly a bust, with cross-shore winds and lumpy slop. The first real chance comes on Monday afternoon, September 7th, and that’s the one to watch.
On that Monday afternoon, the wind turns light cross-off from the ESE at 9 mph, and the swell comes up to 8 ft from the WSW. The period is a very long 15 seconds – that’s real groundswell. The energy is massive (3311), so this is serious. At over 8 ft, this is only for the experienced crew, but the clean conditions, long period, and that direction will line up some excellent, powerful sets. The water is 80°, which is about normal for this time of year.
Tuesday morning, the 8th, is also worth a look. The wind goes light offshore from the SSE at 9 mph, with a 5 ft NE swell at 11 seconds. Clean and glassy, with solid energy (788). That’s a good morning for a fun session.
After that, it’s back to the struggle. The rest of the forecast is filled with ENE cross-shore winds and average surf. There’s a moment on Tuesday the 15th with an 8 ft ENE swell, but the wind is still cross and the conditions are only marginal. For a spot that rarely breaks, this is a tough stretch.
If you’re an expert, lock in Monday the 7th afternoon. That’s your best bet.
Rusty.

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.
