The Lowdown
G’day, Rusty here, your local surf reporter. Let’s have a look at what’s on offer at Turtle Cove over the next couple of weeks.
Alright, so the pattern is a bit of a mixed bag. We’ve got a solid pulse of swell early on, but it’s coming with some gnarly wind, so it’s not a total write-off, but it’s not exactly user-friendly. The best windows are tight and specific, so you’ll need to pick your moment.
First up, Monday the 3rd of August. There’s a big 10ft S swell rolling in with a short period of 8 seconds and combined energy of 1164, which is strong. But the wind is howling out of the SSW at 28 mph as a cross-offshore, so it’s not going to be clean. The water is sitting at 69°, which is a bit colder than normal for this time of year. Honestly, this is more for the experienced crew who don’t mind a fight. The afternoon stays similar.
The real standout is Tuesday morning, the 4th of August. The swell drops to 4ft from the SSW, period still short at 8 seconds, but the wind turns glassy out of the west at 3 mph. That’s a major positive. It’ll be clean, with moderate energy (201). This is your best bet for a cracker session if you can get out there. The afternoon gets crossed up.
Wednesday morning the 5th of August is another good call. The swell bumps up a touch to 5ft from the S, period 8 seconds, and the wind is light offshore from the WSW at 3 mph. Combined energy of 292, and it’ll be clean. Not quite the winner of Tuesday morning, but a solid option.
After Wednesday, things get a bit ordinary. The swell drops off and the wind stays cross-offshore or cross-shore for days. Thursday the 6th, Friday the 7th, Saturday the 8th, and Sunday the 9th all have small, messy surf with poor conditions. The best you’ll get is “surfable but very ordinary.” There’s a gap of almost a week of average to poor surf.
There’s a little flicker of hope on Saturday the 15th of August. The morning has a glassy wind from the ENE at 3 mph, with a 3ft S swell at 7 seconds. It’s small, but combined energy is 80 and it’ll be glassy. Worth a look if you’re desperate for a slide.
The rest of the run into the second week stays small and weak. Monday the 17th and Tuesday the 18th are all tiny, with poor conditions. Nothing to get excited about.
So, the standout is Tuesday morning the 4th of August: clean, glassy conditions on a manageable 4ft SSW swell at Turtle Cove. Get it while it’s good.
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.
