The Lowdown
Alright, this is Rusty.
Look, I’ve got to be straight with you – the outlook for Turtle Cove over the next sixteen days is pretty grim. We’ve got a lot of days with poor surf conditions and not much to get excited about. For the first few days, it’s all small and messy. Saturday the 12th is a write-off with tiny 1ft swell and onshore winds from the east.
There’s a slight flicker on Sunday the 13th. The morning brings a bit of a pulse, with a 3ft swell from the SSE, but it’s only a 5-second period – that’s weak, short-period wind swell. The magic here is the wind: offshore from the west at just 3 mph. That means it’ll be glassy clean, which is a major positive for a spot that is exposed to the southeast. The water temp is sitting at 69°, which is about normal for this time of year. Combined wave energy is weak (82). It’s surfable but very ordinary. The afternoon on Sunday cleans up again with a light cross-offshore wind from the NNW and a 2ft swell. The energy is slightly better at (91), but still small.
After that, we hit a long dry spell. From Monday the 14th through to Monday the 21st, it’s mostly junk. Onshore winds, small chop, or just flat. The wind gets nasty starting from the 21st, with strong breeze cross-onshore winds and building swell, but it’s all messy. On Monday the 21st, we see 6ft swell from the ENE, but the wind is 25 mph cross-onshore, creating horrible conditions. The combined energy climbs to (230), which is moderate, but for paddle surfing it’s a no-go – this is more of a kite surfing setup.
Then around Wednesday the 23rd and Thursday the 24th, the swell really ramps up. Wednesday morning has 6ft from the ESE with a period of 8 seconds, but it’s accompanied by a near gale from the NE at 34 mph. The wave energy is very strong (422), but the place is blown out. Thursday the 24th gets even bigger, with a 7ft swell from the ESE and a period of 9 seconds, but again, 34-37 mph onshore winds. The combined energy peaks at (1447), which is very strong, but for anyone but an expert in a jet ski, it’s unsurfable.
The best wave quality in the whole outlook is still that small, clean Sunday the 13th. It’s not a standout by any stretch, but it’s the only window where the wind and swell align into something that isn’t a total mess. After that, it’s a long, bleak run of onshore slop and gale-force winds that will keep Turtle Cove looking ugly until at least the end of the month. It’s one of those periods where you just have to wait for the next pattern change.

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.
