The Lowdown
Alright folks, this is Rusty pulling up the forecast for Turtle Cove. I gotta be straight with you – the next 16 days are looking like a write-off, pure and simple. I’m not seeing any decent surf on the horizon. The first recommendation doesn't even pop up until the 7th of September, and even then, it's a sad little 1 out of 10 score for "surfable waves but very ordinary conditions." You’re looking at a solid five-day gap of nothing but flat, poor conditions before that.
The swell energy is just pathetic for the first week, with the combined energy barely scraping into double digits, like 88 (weak) and 49 (weak) on the 3rd, 36 (weak) on the 4th. It’s all small, short-period slop. The wind is a mess, too – mostly cross-off or cross-on, nothing that’s going to clean it up. For a reef and point setup like Turtle Cove, which needs that SE swell direction, it’s just not happening.
Now, there is a blip of energy on the 10th of September. The combined energy jumps to 454 (strong) as a 7ft swell from the SSW hits. But that’s a massive red flag. The wind is howling at 25 mph from the SW, which is a strong breeze. That’s not a surf forecast; that’s a kite-surfing forecast. The quality is rated as "poor surf conditions," and honestly, for a paddle surfer, you’d be mad to get out there. The swell is too big for anyone but an expert, and the wind is just nasty.
After that, it fades back into small, weak, and ordinary conditions through the second week. The 13th, 16th, and 17th of September show some light offshore or true offshore winds, which is a good sign, but the swell is tiny – 2ft at best – and the energy is weak (75, 38, 30). It’s the kind of stuff that might be a fun little session if you’re desperate, but it’s not a standout. The water temp is about 70°F, which is pretty normal for this time of year, so at least you won’t freeze waiting for a wave that never comes.
Bottom line: don’t hold your breath. This is a blank run that’s pretty normal for the area when the swell alignment is this bad. Forecasts can change, but right now, I’d be finding something else to do with the next two weeks.

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.
