The Lowdown
Alright folks, Rusty here. Let’s be straight with you – this Turtle Cove outlook is a tough one. We’re looking at a 16-day window with no real quality surf on the cards. The whole period is a write-off for decent waves, so if you’re itching to paddle out, you’re going to be disappointed.
The first few days are a no-go. Tuesday the 28th of July has weak, tiny swell around 2 ft from the SE, but with a solid 15 mph cross-shore S wind, it’s just messy and weak (combined energy of only 49). Wednesday the 29th sees a bump in height to 4 ft under onshore ESE winds, but the period is a shocking 5 seconds – that’s just wind chop with no power (energy 119). It’s a poor surf conditions call all the way.
We get a brief glimmer on Thursday the 30th of July. The morning shows 4 ft from the SSE with a 9-second period and a cross-offshore NNW wind at 12 mph. The wave comment says “marginal” but it’s the cleanest we’ll see in the first week (energy 205). That afternoon stays clean with a light SW breeze, but the swell is small and ordinary. This is the best of a bad bunch, but it’s not a standout.
The rest of the first week and into August is a desert of tiny, weak swell and poor conditions. Friday afternoon the 31st has glassy conditions with 3 ft from the SSE, but it’s just not enough to get excited about. We’re looking at days of 1 ft to 3 ft with cross or onshore winds. The water temp is a bit colder than average at 68°F with a -3°F anomaly, so it’s a little nippy for this time of year.
The second week is even worse. From Sunday the 2nd of August right through to Monday the 10th of August, the swell barely gets above 2 ft, and the combined energy is often in the double digits or low 100s. There’s a period of clean offshore winds on the 9th and 10th, but with only 1 ft to 1 ft of swell, it’s a flat spell, not a surf session. The only notable bump is on Tuesday the 11th of August with 5 ft from the NE, but it’s sloppy under a cross-onshore ENE wind and the energy is moderate (208), but the conditions are poor.
Bottom line: there’s nothing here to recommend. Turtle Cove is a reef and point that needs a decent SE swell to work, and it’s just not getting it. The consistency is “fairly consistent” but the quality is zero. For a spot like this, a blank run like this is more normal than you’d hope. Keep your board in the car and wait for the next system.
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.
