The Lowdown

Alright, grab your board and let’s talk about the next couple of weeks at Turtle Cove. It’s a reef and point set-up, a spot that knows how to hold a swell when it wants to, but honestly, it’s going to be a waiting game for most of this stretch. The water’s running about average for this time of year, so no wild surprises there – just the usual conditions.

The start of this outlook is pretty bleak. From Saturday, August 15th, right through to Monday morning the 17th, there’s barely a ripple. We’re talking ankle-biters, with combined energy readings like 23 and 8. The wind is all over the place, mostly light but onshore or cross. Don’t even bother paddling out – it’s dead.

Then, a pulse of life hits on Monday morning, August 17th. The swell bumps up to 5ft, coming out of the SSW with a period of 7 seconds. The energy jumps to a moderate 413. It’s going to be a bit lumpy and short-period, but the wind turns offshore from the WNW at 12 mph, and that’s a big deal. It’ll clean it up nicely. Monday afternoon keeps that offshore flow, a bit lighter at 9 mph from the West, and the energy settles to 254. That’s the standout window. We’re looking at a peaky, punchy wave, maybe 5ft of it. The wind will be making it glassy. For a seasoned intermediate, that could be a lot of fun. That’s the best call for the whole 16 days.

After that little burst, the plug gets pulled again. Tuesday the 18th drops back down to around 2ft, and the long dry spell begins. From Tuesday the 18th through to the 25th, it’s a frustrating run of small, weak surf. Energy readings hover in the 30s, 50s, and 80s – just weak. There’s a slight bump on the 21st with a cross-onshore chop, but it’s not worth a second look. The wind is mostly cross-off or cross, and the swell is just sad and under 3ft. This is a long stretch of nothing. We’re talking about eight days of poor to non-existent surf.

Finally, on the morning of Tuesday, August 25th, the status ticks up to “surfable but ordinary.” The swell is still tiny at 1ft, but the period stretches out to 11 seconds. Energy is weak at 58. There’s light cross-off wind, so it might be clean but there’s just no push. It’s a tease. The afternoon kicks up a bit more wind but nothing else.

Thursday, August 27th, offers a final glimmer. The afternoon shows some offshore wind (moderate from the West at 12 mph), and the swell holds at a modest 2ft from the SE with a 10-second period. The energy is up to 118 – moderate for this spot. It’s ordinary, but clean. That’s about as good as it gets in the second week. It’s worth a look if you’re desperate for a slide, but it’s not going to set the world on fire.

Honestly, the standout here is Monday, August 17th. Everything else is a scrub. The long gaps in between are brutal. If you can only surf one day, make it that Monday.

That’s the long and short of it.

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.
