The Lowdown
Alright folks, Rusty here. Let’s have a look at what Turtle Cove has in store.
Right off the bat, I gotta tell ya, this stretch ahead is a real test of patience. For the first few days, we’re looking at next to nothing. Thursday the 13th and Friday the 14th, the swell is barely a whisper at 0.3ft to 1ft, and even though the wind is offshore, there’s just no energy to work with. The weekend doesn’t get any better—Saturday and Sunday, the 15th and 16th, are flat to tiny with messy cross-shore winds. You’d be better off doing something else. That’s a solid four-day gap of no real surf to start.
Then, finally, things start to stir on Monday the 17th. That morning is our one true standout. We’ve got a pulse of swell from the SSW pushing 5ft with a period of 8 seconds. It’s not a long-period groundswell, but the combined energy hits a moderate 298, so there’s some push behind it. The wind is offshore from the NNW, blowing at a gentle 9 mph, keeping the surface clean. This is the best on offer without a doubt—a solid, rideable wave for an intermediate surfer. Just a heads up, this spot can get crowded sometimes, and a 5ft swell at a reef and point break like this can get a bit much for beginners.
Monday afternoon fades a bit, and Tuesday the 18th goes right back to poor conditions with onshore winds. Wednesday the 19th offers a sniff of a wave, but it’s ordinary. We get a bit more life on Thursday the 20th with a 3ft southerly swell in the afternoon and clean wind, but nothing to write home about.
The real wildcard shows up way out on Thursday the 27th and Friday the 28th. There’s a bigger, 6ft easterly swell rolling in, but the wind is onshore from the ENE or cross-onshore from the SE. The combined energy is strong, reading 256 and 248, but with the wind blowing on it, the quality is marginal at best. The water temp is a balmy 71°F, which is pretty normal for this time of year. For the rest of the second week, it’s mostly tiny and clean, but unexciting.
So to sum it up: if you’re hanging for a wave, Monday the 17th morning is your window. It’s clean, it’s got some push, and it’s the best we’re gonna see. The rest of the 16 days is mostly a waiting game.

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.
