The Lowdown
Alright folks, Rusty here. Let's have a look at what's coming our way.
Alright, we’ve got a bit of a mixed bag on the horizon. The first few days are going to be a battle with the wind, but there’s some real quality stashed further out if you've got the patience. The water is sitting at 74°, which is about 1° warmer than usual for this time of year, so nothing too wild there.
The first real chance to get wet is Monday morning. It’s a bit of a grumpy start with a cloudy sky and a cross-off wind from the SSE blowing at 19 mph. The swell is a solid 7 ft from the SW with a 13-second period, which brings a lot of energy with it (1474). It’s a fair bit of swell for the average punter, though. The wind is a little fresh, so it’ll be clean but a bit on the challenging side.
Tuesday afternoon shapes up a little better. The wind drops for a cleaner session, but the swell has backed off a touch. We’re looking at 6 ft from the SSW, still a decent 14-second period, and the energy is pumping at 1820. The wind is cross-off from the SSE at 19 mph, keeping it smooth.
Now, if you’re looking for a standout, you need to wait for Thursday morning, July 23rd. This is the pick of the first week. The wind finally swings offshore from the ENE at 22 mph, and it’s going to be glassy clean. The swell is 5 ft from the SW with a very long 16-second period. That’s proper groundswell, and on a reef like Turtles, it’s going to be something special. The energy is strong at 1281. This is advanced territory for sure, but for those who can handle it, this is the window.
Friday, July 24th is a nice little runner-up. The swell drops to 4 ft, but the wind stays offshore all day, going from 19 mph in the morning to a lighter 12 mph in the afternoon. It’ll be clean and fun, but not as powerful as Thursday.
After that, the swell drops off a cliff for the weekend, with waves barely scraping 3 ft. It’s not a complete write-off, but you’ll be hunting for scraps.
The next real blip of interest is further out. Look at Tuesday, July 28th. The morning session has an offshore breeze from the E at 9 mph, and the swell is back up to 6 ft from the SW with a 13-second period. That’s a lot of water moving around (1258), and it’s going to be clean. That’s a session for the experienced crew, as it’s getting a bit big for the average joe.
Then Wednesday, July 29th morning is another solid option. The swell is 5 ft from the SW, 14-second period, and the energy is high at 1691. The wind is a light cross-off from the NE at 6 mph, so it’ll be nearly glassy. Another cracker for the advanced surfer.
The end of July and start of August gets a bit messy again with strong onshore winds and a drop in wave height. There’s a gap of a few days with nothing really worth paddling out for. Monday, August 3rd has a morning offshore wind, but the swell is only 4 ft, so it’s a small cleanup job at best.
Signing off, 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.
