The Lowdown

Alright mate, Rusty here. Let’s have a good look at what’s on the cards for Turtle Cove.

Honestly, the next 16 days are a bit of a flat spell for Turtle Cove. There’s a lot of poor surf conditions and not much to get excited about. The energy is weak for most of this run, with the combined swell energy sitting mostly in the double digits, like 42 to 101, which is pretty weak. We’ve got a few surfable windows, but nothing that’s going to have you skipping work. The water temp is about average for the time of year, so nothing wild there.

The first real chance to get wet is Sunday, the 23rd of August. Early morning there’s a risk of thunderstorms, but the wind is a light cross-off from the SW, making it clean. The swell is a tiny 2 ft from the SSE with a short period of 5 seconds, so it’s not pretty, but it’s surfable. The afternoon cleans up even more with a moderate offshore from the WSW, and the swell lifts a bit to 4 ft from the S. The energy is still weak at 90, but it’s the best of the first week. It’s a reef and point setup, so that short period swell won’t do much, but the offshore wind will keep it tidy.

Monday the 24th has a similar look in the morning – 3 ft from the S with a clean offshore from the W, but the energy is only 113. It’s surfable, but ordinary. The rest of the week is pretty much a dud, with tiny waves and cross-onshore winds.

There’s a gap of a few days with nothing worth mentioning, then we get a bit of a pulse around the 1st of September. Tuesday morning the 1st, the swell drops to 5 ft from the SW with a period of 6 seconds, but the energy jumps to 334 – that’s moderate energy for the first time. The wind is a clean cross-off from the SW, so it’s decent. The swell is 5 ft, which is fine for intermediate surfers, but it’s still short period, so it’ll be a bit lumpy. The afternoon is similar but the wind picks up to a fresh breeze, so keep it to the morning.

The 4th of September Friday afternoon sees a bit more size, with 6 ft from the S and a period of 7 seconds, plus energy at 266. The wind is clean, cross-off from the SSW. That’s the biggest swell of the whole outlook, but it’s still short period and borderline for beginners. It’s a marginal call on the tide.

Overall, the standout is Sunday afternoon the 23rd of August – clean offshore wind, 4 ft from the S, and it’s the first real chance to get a wave. The secondary best is Tuesday morning the 1st of September, with the best energy and clean conditions. No big groundswells, no long period, just a few windows of clean, small surf.

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.
