The Lowdown
Alright, this is Rusty. Let’s talk about what’s going on at Turtles (Turtles-2). It’s a reef break that’s exposed to the swell, and it’s pretty consistent, but we’ve got a 16-day window here, and it starts off with a bit of a slow burn.
The first couple of days, Thursday the 16th and Friday the 17th, are a total washout. Poor surf, cross-onshore winds, and the wave energy is just moderate (986 and 896). The water’s sitting at 73°F, which is about normal for this time of year, so nothing special there.
Saturday the 18th shows a little bump, but it’s still marginal. The morning has a light cross-shore wind and a 6ft swell from the WSW, with a 14-second period. The energy is moderate (1125). It’s not clean enough, though. The afternoon goes onshore, so it’s a pass.
Now, Sunday the 19th of July – that’s the one. The morning is where it’s at. We’ve got a solid 8ft of WSW swell, a 16-second period – that’s a long-period groundswell – and it’s packing some serious energy (3076). The wind is from the ESE, light, and cross-offshore, which means it’s going to be glassy clean. This is a reef break, so with that long period, it’ll set up well, but it’s big enough that it’s only for experienced surfers. Crowds are often a thing here, so expect a few others out.
Monday the 20th is a decent follow-up. Swell drops to 6ft from the SW, period 13 seconds, with a clean cross-off wind from the SSE. Energy is moderate (1179). It’s a good day, but not the standout.
The rest of the week into the 21st and 22nd goes smaller and windier, with the energy dropping off. The 23rd sees a return of 7ft swell from the SW, but it’s a fresh cross-off wind, so it’s clean but not perfect.
Looking into the second week, things get smaller and more inconsistent. The 24th and 25th have some clean offshore winds, but the swell is tiny – 4ft and then 3ft. The energy is weak (570 and 269). It’s a lull.
Then, on the 29th of July (Wednesday morning), there’s a nice little glimmer. A very clean, light cross-off wind, and a 3ft swell from the WSW with a very long period of 20 seconds. That’s a proper groundswell, and the energy is moderate (793). The guidance says “very good surf conditions.” This one is promising, but it’s a long way out, so don’t lock it in yet.
The 30th and 31st of July see a return to bigger swell – 6ft to 8ft from the WSW, with periods of 18-19 seconds, and strong energy (2588 to 3139). The wind is cross-off or cross, so it’s clean in the mornings but the afternoon gets lumpy. The 31st morning looks like the best of that late run, but it’s still a bit of a gamble being so far out.
Bottom line: the best on offer is without a doubt Sunday the 19th of July morning. That’s the one to get after. The second week is quieter, with that 29th of July morning being a promising but less certain standout.
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.
