The Lowdown
Alright folks, Rusty here. Let's be straight with you – this outlook for the next couple of weeks is a tough one. We've got a solid run of days ahead where the surf just isn't going to cooperate, so patience is the name of the game.
We're looking at Turtle Cove, a reef and point setup that usually needs a good SE swell to get going. The water temp is sitting right where it should be for this time of year, so no surprises there.
The forecast kicks off with a bit of energy on Wednesday July 29th, with chest high sets around 6 ft coming from the SSE, but the period is a short and weak 6 seconds. That combined energy reading of 279 is moderate, but the wind is howling out of the ESE at 19 mph, putting a nasty cross-on chop on the surface. It's a write-off for a paddle surf. Thursday July 30th morning is a little better, with the swell dropping to 5 ft, still SSE, but the period stretches to 8 seconds. The wind swings NW at 9 mph, giving us a clean cross-off breeze. The energy is still moderate (289), but the clean conditions make it a possibility for an intermediate surfer. That afternoon, the wind picks up again, and the swell fades.
From Friday July 31st right through to the end of the first week, the wave heights drop under 3 ft, and the wind is mostly onshore or cross-shore from the NE, E, and SSE. The energy drops into the weak double digits, (36-99). It's small, choppy, and just not worth paddling out for.
The second week is more of the same. There's a brief moment on Tuesday August 4th morning where the wind turns offshore from the W at 19 mph, making it clean, but the swell is a weak 3 ft from the S with a short 7-second period. The energy is only 107 (moderate), but it's clean. Still, it's not a standout. The rest of the week and into the next offers nothing but ankle-biters, with wave heights consistently below 2 ft, weak energy (21-50), and short periods. Even the glassy conditions on Friday August 7th morning can't save a swell that is basically flat at 1 ft.
So, the honest truth is there are no true standouts in this 16-day window. The only day that offers a glimmer of hope is Thursday July 30th morning, with a clean 5 ft SSE swell at Turtle Cove. It's a one-day-only option in a long stretch of poor conditions. For the rest of the time, the small, weak swell and mostly onshore winds mean you're better off keeping the board in the shed.
Stay patient, and keep an eye on the horizon.
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.
