Table - best surf conditions forecast for Turtle Cove over the next 16 days.
G’day, Rusty here, and I’ve just had a good look at the forecast for Turtle Cove. Honestly, it’s a pretty grim run for the next couple of weeks. There’s definitely a long stretch of nothing worth getting excited about, so I’m going to be straight with you—this is a lean period.
The first worthwhile surf doesn’t even show up until Wednesday the 15th of July, and even then, it’s a pretty ordinary offering. We’ve been waiting through a few days of flat, messy conditions before that. From Wednesday morning, we’ve got a 4ft swell from the southwest, with a short period of 7 seconds. The combined energy is moderate (171), but the waves are going to be a bit lumpy. The wind is offshore from the west at 12 mph, which will keep it clean, but this is a beach-and-reef setup, so the short period means the waves won’t have much shape. It’s really just a marginal session for the die-hards who need a paddle.
The water temperature at Turtle Cove is sitting at 66°, which is a bit colder than average for this time of year—about 4° cooler. Not a huge shock, but you’ll be wanting a thicker wetsuit.
The best chance across the whole 16 days, the only real standout, is on Tuesday the 21st of July. Tuesday morning, we’ve got a 5ft swell from the south, with a period of 9 seconds, and the combined energy is solid (308). The wind is cross-off from the SSW at 9 mph, keeping it clean. The break is a reef and point, and with that longer-period swell, it’s going to produce some decent, well-shaped lines. The optimum swell direction for Turtle Cove is southeast, so this south swell is a bit off, but it’s still the best we’ll see. There’s not much crowd pressure mentioned, but on a morning like that, it could get a few locals out.
After that, the surf drops off again. The rest of the second week and into the final days shows nothing but tiny, weak swells—mostly under 2ft—and poor conditions. The 26th of July has a small blip of 3ft from the southwest with offshore wind, but it’s a short period and the energy is weak (52). Not worth rushing for.
So, to sum it up: if you’re free on the morning of Tuesday the 21st, get down to Turtle Cove. That’s your wave. The rest of the 16-day window is mostly a write-off, with long gaps of nothing. But hey, it won’t stay poor forever.
Rusty.

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