The Lowdown

Alright, Rusty here, sizing up Turtle Cove for the next 16 days. It’s a reef and point, so it’s got character.

We’re in a slow spell from the start through the 23rd of August. The swell is tiny or weak, and the wind is mostly onshore or messy. You might get a few rideable ones, but nothing to chase. Water temp is about normal for the season.

First decent pulse hits on the 24th of August. Swell comes in at 4ft from the S, with a 7-second period. The energy is 158 (moderate). The wind is clean cross-off. It’s a solid start to the week.

The 25th of August morning is a real standout. Swell is 4ft from the SSW, period 7 seconds, and the wind is glassy. The energy is 171 (moderate). That’s a clean, smooth dawn patrol. Get on it.

Things get messy again with storm risk until the 28th of August. That Friday morning is the big one. Swell is 6ft from the S, period 7 seconds, and the energy hits 373 (strong). The wind is clean cross-off. That’s proper, powerful surf. It’s a bit on the bigger side, so know your limits. The 29th of August holds with a 4ft S swell and offshore wind, keeping it clean.

The 31st of August afternoon has a 6ft ENE swell. The period is short at 6 seconds, but the energy is 283 (strong), and it’s clean. It’s a bit wind-affected, but still a fun wave.

The 1st of September finishes strong. The morning is 4ft from the SSE with a clean cross-off, and the afternoon is glassy with 4ft from the SSE. That’s a classic, clean day at the point.

Best bets: the 25th of August morning for the glass, and the 28th of August for the size. The 1st of September is the cleanest, most consistent option at the end.

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.
