The Lowdown

Alright folks, Rusty here. Let’s take a look at what’s cooking at Turtle Cove over the next couple of weeks.

Alright, straight up: this is a tough outlook. We’re looking at a long stretch of pretty poor conditions, with only a few fleeting moments that might be worth a paddle. The water temp is sitting at 72°F at the start, which is just about average for this time of year, so nothing weird there.

The first real chance to even think about it doesn’t come until Monday the 24th of August. Monday morning sees a clean, offshore wind from the West, with a 3ft swell from the SSW. The period is a short 7 seconds, so it’s a bit of a weak, local wind swell, but the wind is fresh offshore, so the surface will be clean. The combined energy hits 121 (moderate), but the wave comment says it’s still poor surf. It’s a marginal call for a paddle.

Tuesday the 25th of August morning is similar but smaller, with 2ft from the SSW, clean offshore wind, and a score just barely above zero. It’s surfable, but very ordinary.

Now, the best of the bunch pops up a few days later. Friday the 28th of August. This is the standout. The afternoon sees a jump in size. We’ve got a 5ft swell from the South, with a period of 9 seconds, and a cross-offshore wind from the SSW making it clean. The combined energy jumps to 374 (strong). This is a solid, clean wave on offer. The swell direction is from the South, which is the optimum for this spot. It’s a reef and point break, so it should handle that swell well. It’s not huge, but it’s the best looking day in the whole window. For a more experienced surfer, this is the one to circle.

After that, it drops off again. Saturday the 29th of August morning has a clean 3ft with offshore wind, but it’s weak. The first week of September sees a few more small, clean days, but nothing that will get your heart racing. Tuesday the 1st of September actually pushes 6ft from the SSW, but the wind is onshore or cross-onshore, making it choppy and messy. That one is a write-off for a surfboard.

So, overall, there’s a big gap of poor-to-no surf from now until the 24th, then a few marginal days. The one true standout is Friday the 28th of August afternoon. Get on it if you can, but don’t get your hopes up for the rest.

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.
