The Lowdown
Righto, let's have a look at what's on the menu for the next couple of weeks. I gotta be straight with you, it's a bit of a lean spell. The forecast is looking grim for most of the period, with a lot of small, messy, or wind-affected surf. We're gonna see a lot of days where it's just not worth paddling out, so be patient.
The first spot on the radar is Turtle Cove, a reef and point setup. The water temp is sitting at 71°, which is pretty much bang on average for this time of year, so no surprises there.
The first readable session doesn't pop up until Monday, August 26th in the morning. It's a tiny 2 ft swell from the ESE with a 9-second period, and the wind is light offshore from the WNW. It's surfable, but very ordinary. The combined energy is a weak 59. Nothing to get excited about, but it's clean.
We then hit a long, dry patch. The next glimpse of something possible comes on Tuesday, September 1st. The morning session is glassy, with a light wind from the NE, which is a huge positive. The swell is small at 2 ft, but it's from a very long 16-second period groundswell (combined energy 179). That long period will give it some shape, but it's a southeast swell, and the optimum direction for this spot is SE, so it's a good match. However, it's tiny, and the long period might make it close out at a beach break, but being a reef and point, it should handle it better. The Tuesday afternoon is also clean with a 2 ft, 14-second swell, but the wind turns cross-off. These are the best on offer, but they're still not standouts.
After that, we're back into a poor stretch. The end of the window on Tuesday, September 8th shows a clean morning with a 3 ft ESE swell and a moderate offshore wind from the WSW (combined energy 113). It's surfable, but again, nothing to write home about.
Honestly, if you're desperate, the Tuesday, September 1st morning session at Turtle Cove is the pick of a very poor bunch. The glassy conditions and the long-period groundswell matching the optimum direction are the only real positives. The rest of the forecast is a write-off. The setup and the wind for the last week look more interesting for kite surfing than paddle surfing, to be honest.
Keep an eye on the charts, but for now, I'd save your energy.

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.
