The Lowdown
Alright, Rusty here again. Let’s break down JT Flemming in the old measurements. This is a point break that’s a rare beast—it hardly ever breaks, but when it does, it’s a fun wave for beginners. The water’s about 80°F, which is normal for the season.
The first few days are a bust. Saturday and Sunday are blasted by cross-shore winds, making the surface lumpy. You’ve got waves around 5 to 6 feet from the ENE, but the wind is just trashing it. The wave energy is moderate, around 940 to 1116, but it’s not worth the hassle.
The only real window is Tuesday, the 8th of September. Monday is still a bit rough, but Tuesday morning is the gem. The swell is a clean 6 feet, and the wind turns light offshore from the SSE at 9 mph. That’s glassy, clean, and perfect for a point break. The combined energy is 1288 (moderate), and with a 11-second period, you’ve got some real push. The swell is from the WSW, not the ideal NNW direction, but the offshore wind makes up for it. This is a rare chance for a clean wave at a spot that’s not often working. Tuesday afternoon drops to 4 feet, but still clean.
From Wednesday the 9th onward, it’s a long, flat, and choppy stretch. The wind stays onshore, the swell periods drop to 6-8 seconds, and the energy is mostly under 400 (weak). Waves are between 3 and 7 feet, but they’re messy, lumpy, and not worth your time. For a spot that’s already inconsistent, this is a normal dry spell.
So, your one and only call: Tuesday morning, 8th September. Be there or miss it.
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.
