The Lowdown
Alright, fellow wave hunters, it’s Rusty here. Let's have a look at what Turtle Cove has in store for us over the next couple of weeks.
Honestly, for the first week, it’s a bit of a slow grind. We’re looking at some real small stuff, nothing to get excited about. The water temp is sitting at a pretty average 71°F for this time of year, so no surprises there.
The first real chance to paddle out comes on Monday the 24th of August. The morning session is your best bet. We’ve got a 3ft swell pushing in from the South, with a gentle offshore wind from the WSW (9 mph), which will keep the surface clean. The period is a short 6 seconds, so it’s not gonna have much punch, but it’s surfable. The combined energy is weak (87). The afternoon goes downhill with a cross-off breeze, so get it while you can.
The next few days are tiny. Tuesday the 25th is a non-event with 1ft slop. Wednesday the 26th has a bit more size but still ordinary. The whole week is a struggle for any kind of quality.
Now, we get a little glimmer on Saturday the 29th of August during the morning. It’s still only 2ft from the SE with an 8-second period, but the wind goes glassy – ENE at 3 mph. That’s a major positive. The waves will be clean, but don't expect much power. The energy is weak (86).
Then there’s a long gap of nothing really good until we hit the first week of September.
Things start to wake up. The afternoon of Wednesday the 2nd of September is where it gets interesting. We’ve got a 3ft SE swell creeping up, but the period is a solid 12 seconds, and the combined energy is pushing into moderate territory (254). The wind is a light cross-off from the SSW, so it’ll be clean. This is a standout session for the patient surfer.
The next morning, Thursday the 3rd of September, sees the swell build to 4ft from the SE with a 13-second period (energy 348). The wind is cross-shore out of the north, so it’s a bit grovelly. The afternoon is similar, but the wind swings NW (cross-off) and the energy jumps to 444. It’s a bit marginal with the tide and wind, but this is the biggest, most consistent window in the whole forecast.
Hold on though, because the real standout is pencilled in for Saturday the 5th of September. The morning session is the pick of the entire 16 days. We’re looking at a 5ft swell from the East, with a light cross-off breeze from the SW (6 mph). The conditions are clean. The energy is strong (336). This is a proper push of swell, with a period of 8 seconds. It’s not too big for most, but intermediates should have a blast. The afternoon is a bit bigger and messier with a stronger cross-off wind, so stick to the morning.
After that, Sunday the 6th and Monday the 7th still have some size (3ft to 4ft) but the winds get stronger and the conditions get more marginal. Not a total write-off, but the Saturday morning is your golden ticket.
So, to wrap it up: the first week is a write-off. The second week delivers. The absolute standout is the morning of Saturday the 5th of September at Turtle Cove, with a clean 5ft E swell. That’s the one to circle on the calendar. Keep in mind, the spot is fairly consistent, but it can get crowded, so get in early.
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.
