Table - best surf conditions forecast for Turtle Cove over the next 16 days.
Alright mates, let's break down what Turtle Cove has cooking for us.
The water temp is right around 67°, pretty standard for this time of year. Nothing to write home about.
Honestly, the first stretch is a real bummer. From Wednesday the 8th right through to Saturday the 19th of July, it's a long dry spell. There's a little blip around the 16th, but the wind is all wrong and the energy is pathetic. We're talking ankle-snappers with onshore junk. Don't bother paddling out.
The payoff is at the very end of the forecast. The one to get amped for is *Monday the 20th of July*. That morning, Turtle Cove gets a solid 7ft south swell, with a 9-second period. The combined energy is a beefy 582—that's some serious grunt. But the real kicker is the wind: glassy, dead calm. For a reef and point, that's a dream. The waves will be clean, lined up, and holding that south swell perfectly. That's the session to circle. The water will be glassy, and the sets will have some real power.
Later that morning, the wind picks up and chops it out, but that early window is the gold mine. Tuesday the 21st is still okay, with a 6ft south swell and lighter offshore winds, but it's not the same magic as Monday.
So here's the deal: the first 11 days are a total washout. Don't even think about it. But if you can wait, be on the water at dawn on Monday the 20th of July. That's the one.

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.
