The Lowdown
Alright folks, Rusty here. Let’s have a look at what’s on the cards for the next couple of weeks.
The first real action we’re looking at is a bit of a slow burner, but there’s a standout window that’s worth keeping an eye on. We’ve got a gap in the action before things kick off, but once they do, there’s a window of classic groundswell with some solid energy.
The first proper session to get excited about is Thursday morning, July 23rd at Turtles (reef). We’ve got a clean 6 ft SSW groundswell rolling in with a long period of 16 seconds, and the wind is a fresh offshore breeze out of the east at 19 mph. That’s a recipe for some clean, lined-up reef waves. The combined energy is strong at 1392, so there’s plenty of punch. This is a spot for advanced surfers – the long period and decent size will make it a real test, but for those who know the reef, it’s going to be the pick of the bunch. The water temp is about average for the time of year.
If you miss that, the next standout is Tuesday morning, July 28th. Another early session with a 6 ft SW swell at 13 seconds, but with a light 6 mph offshore breeze out of the east. That’s almost glassy. The energy is strong again, around 1365. This is a fantastic, clean option for the experienced crew, though crowds are possible at this break.
Now, looking further out, the forecast gets interesting but a bit messy. There’s a big pulse of energy coming through on Monday morning, August 3rd. We’re talking a 8 ft WSW swell with a very long period of 18 seconds. The combined energy is massive at 4944. That’s heavy, powerful water. The wind is a moderate cross-offshore breeze, so it might be clean, but at that size and period, this is strictly for experts. That long-period groundswell can break a bit straight on a beach, but on a reef like Turtles, it’ll be a proper, thumping wave. It’s one to watch, but the wind on the afternoon looks like it will chop it up with a fresh cross-shore.
Honestly, the best of the whole window looks like Thursday morning, July 23rd. That’s the one. Clean, solid, and powerful. The Tuesday morning, July 28th, session is a very close second for cleaner conditions. The big swell on August 3rd is a wildcard – promising, but less certain this far out.
For the rest of the period, there are a few days with clean, smaller waves (around 3 ft to 4 ft) on the Saturday and Sunday, but nothing that’ll get your heart racing. The second week sees a lot of onshore or strong cross-onshore winds messing things up, especially around the 30th and 31st of July, which are write-offs. The swell does build again going into the first week of August, but the wind is a constant battle.
Overall, it’s a tale of two weeks. The first week has a couple of golden windows, but the second week is a dice roll with big energy and tricky wind.

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.
