The Lowdown
Alright, this is Rusty, and I’m looking at the next couple of weeks for Turtle Cove. Gotta be straight with you – it’s a pretty grim run for the most part, with some brief windows of hope if you're patient.
The first real chance to even think about paddling out comes on Wednesday, July 29th. We’ve got a bit of a pulse coming through. The morning sees a 6ft swell out of the SSE, with a period of 7 seconds, and the combined energy is moderate at 382. That’s a bit of a junky, short-period swell, but the wind is a cross-off breeze from the SW at 15 km/h, which will keep the surface clean. It’s not the best shape, but it’s surfable. The water is sitting at 68°, which is a bit colder than normal for this time of year, so don’t forget the extra rubber.
Thursday, July 30th, is the standout, and it’s the best we’re going to get. The morning is the pick: a clean 5ft swell from the S with a 9-second period, giving a moderate energy of 296. The real kicker is the wind – glassy, offshore from the WSW at only 5 km/h. That’s about as clean as it gets. The afternoon holds similar size with a 4ft swell from the S and a light cross-off breeze, so you’d have a decent window. This is the one to aim for. It’s a reef and point setup, and with the swell direction coming from the S, which is close to the optimum SE, it should line up alright.
After that, it’s a long, sad slide. Friday, July 31st, through the first week of August is mostly a write-off with small, weak swells and messy cross-onshore winds. You’ll see a few mornings with glassy conditions, like Saturday, August 1st, but the swell is tiny at 3ft and the energy is low (123). It’s just not worth the effort.
From August 2nd onwards, the swell drops off a cliff. We’re looking at days of 1ft to 3ft surf with barely any energy in the water. The wind is often onshore or gusty, making it choppy and ugly. There’s a very long stretch of nothing here. Around August 7th and 8th, we get some glassy mornings again, but the swell is a pathetic 2ft to 3ft with a short period, so it’s barely a ripple. It’s not going to get your heart pumping.
So, to wrap it up: Thursday, July 30th, is your day. Get out there in the morning for the cleanest, most fun waves on offer. The rest of the 16-day window is mostly a bust, with long gaps of flat, junk surf. Keep an eye on the charts, but don’t hold your breath.
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.
