The Lowdown
Alright, this is Rusty, and I’m looking at Turtle Cove.
Honestly, for the next couple of weeks, Turtle Cove is a bit of a mixed bag. It’s an exposed reef and point setup that ideally wants swell from the SE, and we’re just not seeing that magic combination line up consistently. The water temp is sitting right around 72°, which is pretty average for this time of year, so nothing wild there.
The first week-and-a-half is pretty frustrating. From now through most of the next week, it’s a real grind. You’ll see tiny, weak swells, often with poor wind. The wave energy is mostly in the low double digits (20 to 40 range), which is barely enough to get excited about. There’s a lot of small, short-period windswell and cross-onshore or onshore winds that will keep things messy. You’re looking at a long gap of about 7 days where nothing really stands out as worth paddling out for.
The first real sign of life pops up on Monday, August 17th. The morning sees a bump in swell to 5ft from the SSW, and the wind is a clean offshore from the NW. The combined energy jumps to 268 (moderate wave energy), which is a serious step up. The afternoon gets even better, with a 5ft SSW swell and the combined energy hitting 433 (strong wave energy). The wind is still cross-off from the NNW, which should keep the lineup pretty clean. This is the standout window. It’s not huge, but it’s the best quality we’ll see. The swell direction is a touch off the optimum SE, but with that clean wind and solid energy, it’s the one to aim for. Keep in mind the period is a short 7 seconds, so it’ll be a punchy, fast wave, and the reef bottom should handle that better than a beach break.
The following week is a return to the struggle. The energy drops, and the wind turns onshore from the NE and E, making things choppy. Late in the period, around Saturday, August 22nd, we get a surfable 4ft from the SE with light cross-off wind, but it's just ordinary. Then on Monday, August 24th, we get a glassy morning with a 1ft SE groundswell (12 second period). The energy is weak (68), but it’s glassy, so if you’re desperate for a quiet session on a longboard, you might find a couple of clean little ones. The longer period will make it a bit walled-off at the point, but it’ll be clean.
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.
