The Lowdown
Alright folks, Rusty here. Let’s be straight with you—this 16-day run for JT Flemming is a long, flat stretch of nothing special. A point break that rarely breaks is a tough draw, and the forecast backs that up. We’re looking at a solid 12-day gap from now until the end of July with no real surf on offer. The winds are stuck cross-shore from the ENE, mostly fresh at 30 km/h, and the swell is small, short-period junk. Through Thursday the 16th to Sunday the 27th, it’s a write-off: lumpy cross-chop, poor surf conditions, and a combined energy reading that barely cracks 290 (moderate) on the best afternoon. The water temp is 26° with a +0.2° anomaly, so it’s about average for this time of year.
The only pulse that shows any life comes around the 28th and 29th of July. Tuesday the 28th morning, we see a 2.5m groundswell from the ENE with a period of 13 seconds—that’s long-period energy, and at a point break, it could actually line up with some shape. The combined energy jumps to 2264 (strong), and the wind drops to a gentle 15 km/h cross-shore, keeping things fairly clean. By afternoon, it’s the same story: 2.5m, 13 seconds, energy at 2303. Wednesday the 29th pushes even bigger, with 3.0m swells from the NE, periods of 12-13 seconds, and energy readings over 2900 (very strong). That’s big, powerful stuff—only for experienced surfers, and the crowds are possible here. The wind stays gentle, 15 km/h, but it’s still cross-shore, not pure offshore. This is the standout window, but it’s a long way out, so treat it as promising but not locked in. After that, by Thursday the 30th, it drops back to messy, poor conditions.
So, if you’re a beginner, this whole outlook is a pass. The only real window is that late July groundswell at JT Flemming, and it’s for experts only. Keep an eye on it, but don’t hold your breath.
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.
