The Lowdown
Alright, Rusty here. Let’s have a look at what’s coming up for Turtles.
First up, this spot is a reef break, so it’s a wave that will hold its shape with the right swell, but it’s strictly for the advanced crew. The water temperature is sitting at 75°, which is about what you’d expect for this time of year – nothing unusual there.
The next few days are a bit of a mixed bag. Tuesday afternoon the 21st sees a clean 4ft SW swell with a cross-off wind, but the energy is only moderate (733) and the reports are pretty marginal. Wednesday the 22nd is similar, with a little more size by the afternoon at 5ft and a bit better energy (846), but still not setting the world on fire. Thursday the 23rd is where things start to look up. The morning brings a 5ft SW groundswell with a very long period of 16 seconds, and offshore winds from the east. The combined energy jumps to 1281 (moderate to strong), and it’s clean. That’s a solid session. The afternoon holds up too with a 5ft SW swell, 14-second period, and offshore winds – energy is 998. This is the best of the early window.
Friday the 24th is still clean with offshore winds, but the swell drops to 4ft in the morning and 4ft in the afternoon, so it’s smaller and less energetic. Saturday the 25th and Sunday the 26th are poor – small, weak, and with onshore or cross-shore winds. A couple of days to skip.
Now, Monday the 27th sees a return of 5ft WSW groundswell in the morning with cross-off winds and moderate energy (966), but it gets messy in the afternoon. Tuesday the 28th is similar – clean morning with 5ft SW swell, but the afternoon turns choppy.
The standout in this whole outlook is Wednesday the 29th morning. You’ve got a 4ft SW swell, a long 14-second period, light offshore winds from the east, and the energy is strong at 1188. The report says excellent for experienced surfers. That’s the one to circle. The following morning, Thursday the 30th, is also very good with a 4ft WSW groundswell at 17 seconds, light offshore winds, and clean conditions.
Then there’s a serious spike on Friday the 31st morning. It’s glassy, with a 5ft WSW groundswell at a very long 16 seconds, and the energy is massive at 1453. That’s a session for the crew who know what they’re doing. The afternoon gets a bit bigger at 6ft but with onshore wind and a huge energy jump to 2788, but it’s messy.
The first week of August brings some serious size. Saturday the 1st morning has a 12ft WSW swell, which is big – only for experts – and the energy is a very strong 5081. The wind is cross-off, so it’s clean, but at that size, it’s a beast. Sunday the 2nd is still big at 8ft, with cross-off winds and strong energy (1853). The pick of the second week might be Wednesday the 5th morning: a 6ft SW groundswell at 15 seconds, light offshore winds, and very strong energy at 2128. That’s another excellent session for the experienced surfer.
The best of the best? I’d be looking at Thursday the 23rd morning for that long-period groundswell and clean offshore, and then Wednesday the 29th morning for the light offshore and excellent conditions. The 31st morning glassy session is also a true standout. Everything else is either smaller, wind-affected, or just not clean enough to gush about.
Rusty.

Information about the Turtles Surf forecast
The above surf forecast table for Turtles provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Turtles can be found by selecting the local surf guide option on the grey menu. Our Turtles 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 (Turtles) 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 Turtles 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.
