The Lowdown
Alright folks, Rusty here. Let’s have a proper look at what’s on offer at Turtle Cove over the next couple of weeks. I gotta be straight with you – this is a tough stretch. We’re looking at a long, quiet run before anything worthwhile shows up.
The overall pattern is for a lot of small, weak, and messy surf. For the first week, there’s hardly anything to get excited about. The water temps are sitting around 67°, which is a bit colder than normal for this time of year, so you’ll want that wetsuit.
We’ve got a long gap with no real recommendations until the 20th of July. For almost a week, the wave energy is barely registering, with combined swell energy values like 14 and 11 – that’s super weak stuff. Winds are mostly cross-off or just messy, keeping things clean but offering no power.
Now, the standout window finally arrives on Monday, the 20th of July. The morning session sees a clean 5ft S swell, with a moderate 8-second period. The wind shifts offshore from the W, giving us a clean, gentle breeze. The combined wave energy is a solid 353, which is moderate energy – you’ll feel the push. This is the best day, hands down. It’s not a giant, but it’s a proper, rideable wave.
Then on Tuesday morning, the 21st of July, there’s another shot. A clean 4ft swell from the S, 8-second period, with a light WNW offshore wind. The combined wave energy here is 239, still decent. This is your second-best option, and it’s clean, but the Monday morning is the real standout. Be aware that Turtle Cove as a reef and point break can bring crowds sometimes, so expect some company on the best days.
After that, it fades again. A few marginal days pop up around the 24th and 25th of July, with some longer-period energy (up to 13 seconds) from the SE, and combined energies reaching 304 to 316 – that’s moderate. Winds are mostly cross-off, so it’ll be clean, but the conditions get flagged as marginal, so don’t expect perfection. By the 29th, we get another glassy morning with a 4ft S swell, but the energy is lower again at 160.
Basically, wait for that Monday the 20th. That’s your best chance. The rest is a gamble.
Rusty, signing off.

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.
