The Lowdown

Alright folks, Rusty here. Let’s break down the next couple of weeks at Turtle Cove.

Right out of the gate, Monday morning is a dud. There’s some swell, but it’s messy, the energy is weak at 154, and the wind is making it lumpy. It cleans up a touch in the afternoon, and the energy jumps to a moderate 523, but it’s still a short-period, jumbly 6ft. It’s surfable, but you won’t be bragging about it.

Tuesday and Wednesday are pretty flat. Swell drops below 3ft, and the energy is weak, in the 70s and 120s. There’s a clean 3ft on Tuesday morning, but it’s just ordinary. Not worth the paddle.

From Thursday through the weekend, it’s dead. A proper flat spell, several days with nothing. Swell barely touches 1ft, and it’s mostly cross-onshore chop. The energy is often under 50. Sunday morning is glassy, but there’s only 2ft of swell. It’s a tanning day, not a surfing day.

The start of next week, the 24th and 25th, is still small. The periods get long—12 and 11 seconds—but there's no size. It’s a tease. Tuesday afternoon has a little bump of energy, but it's a poor 5ft with a short period.

Now, Wednesday the 26th brings some size, up to 6ft, but it’s messy with a cross-onshore wind, and the energy is a moderate 412. The period is a short 7 seconds. The report calls it poor. For a reef and point break, that’s a red flag. Don’t get fooled by the height.

The one to wait for is Saturday, August 29th, in the afternoon. That’s your window. We’ve got 6ft of SE swell with an 11-second period, and the energy is strong at 928. But the real kicker is the wind, it’s glassy. Completely glassy. The report says “expect very good surf conditions.” This is the standout of the whole stretch. For the intermediate surfer, this is it. The long period means proper groundswell, and with the glassy conditions, it’s going to be clean. Crowds are listed as “sometimes,” so there’s a chance for some solo waves, but be ready for company.

Sunday morning, the 30th, is a decent follow-up. It drops to 3ft, but there’s still a moderate 266 of energy, and it’s clean with a light offshore breeze. A solid, but less exciting, consolation.

After that, it fades out again into September. Small, weak, and clean, but not surfable. There’s a hopeful signal on the 29th, but it looks like a one-day wonder.

So, be patient. There’s a long flat stretch, some messy junky surf, and then one quality window on Saturday the 29th. That’s the one to mark on the calendar.

Rusty out.

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.
