The Lowdown
Alright folks, Rusty here. Let’s have a look at what’s on the menu for the next couple of weeks.
We’re gonna be honest with you: this is a tough stretch for Turtle Cove (reef and point). Most of the forecast is a write-off, with a solid week of tiny, poor surf right through the first week of September. There’s a big gap with nothing worth paddling out for. The first real glimmer of hope doesn’t show up until Thursday, September 10th, and even that’s a tricky one.
The water temperature is sitting right around average for this time of year at 69°, so no surprises there.
The standout option, and it’s a weird one, lands on Monday, September 14th. The morning session at Turtle Cove sees a jump in swell to 6 ft from the SW. The wind is light offshore from the W, which should leave it glassy and clean. The combined energy is moderate at 273, and while the period is a short 6 seconds, the offshore wind and clean conditions should make it surfable. This is the best on offer, but it’s still a bit of a gamble. That 6 ft is getting into the zone where it might be a little much for beginners, but for intermediates, it could be a fun little window.
Before that, on Thursday, September 10th, the morning actually shows a big spike in energy – 8 ft from the SW with a combined energy of 1192 – that’s strong. But the wind is a strong offshore breeze at 25 mph, which makes it powerful and clean but also a real battle to paddle into. That’s expert-only territory, and even then, it’s marginal. The afternoon drops to 5 ft.
After the 14th, it drops right back off into tiny, ordinary conditions for the rest of the run. The long-range stuff on the 18th and 19th shows some longer period (12 seconds) swell, but it’s only 1 ft, so it’s not going to do anything.
Bottom line: If you’re desperate, the morning of Monday, September 14th is your best bet. Otherwise, it’s a long wait for very little. We’ll see if the forecasts change, but for now, it’s pretty quiet.
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.
