The Lowdown
Right, let’s have a look at what’s on the cards for the next couple of weeks.
Honestly, it’s a pretty poor run for the most part. We’re looking at a long stretch of small, weak surf and average conditions. The window opens with a bit of a whimper and there are long gaps where you’d struggle to find anything worth paddling out for. The only real standout, and it’s a long way off, comes on Saturday the 8th of August.
Let’s start at the beginning. On Thursday the 30th of July, we’ve got a 4ft SSE swell at Turtle Cove – a reef and point setup. The combined energy is moderate at 249. But the wind is a messy cross-shore from the NNE at 15 mph, making for a lumpy, cross-chop. It’s a write-off.
Friday the 31st of July is a bit better. The morning sees a 3ft SSE swell, period of 9 seconds, and a clean, light offshore wind from the west at 6 mph. The wave energy is weak at 132. It’s surfable, but very ordinary. The afternoon turns cross-offshore and the energy drops a touch.
Saturday the 1st of August stays small, with a 3ft S swell. The morning has a gentle cross-off breeze, but it’s still just average. The energy is weak at 163. Not great.
From Sunday the 2nd of August right through to Friday the 7th of August, it’s a real struggle. Swell heights drop below 2ft, periods are short, and the combined energy is mostly in the weak double digits. The morning of Thursday the 6th of August has a clean, glassy offshore from the west, but with only 1ft of swell, you’re just bobbing around. This is a long gap of nothing special.
Now, the one that catches the eye. On Saturday the 8th of August, the morning session at Turtle Cove sees a 5ft SW swell. The combined energy jumps to 356, which is moderate. The period is a short 7 seconds, so it’ll be a bit lumpy, but the wind is a clean cross-offshore from the SSW at 12 mph. This is the best of the lot, but with that short period, it’s not a classic groundswell. It’s surfable, and for this stint, it’s the highlight. The afternoon drops back down.
The week after that fades again. Nothing on the 9th, 10th, or 11th of August is worth chasing. The 12th of August morning has a 4ft S swell with a very short 5-second period and glassy conditions. The energy is weak at 78. It’s surfable, but messy. The afternoon of the 12th picks up a bit with a 5ft SSW swell and 185 energy, but it’s still nothing special.
The rest of the window, from the 13th of August onwards, is all small, weak, and forgettable. If you’re desperate, that Saturday the 8th of August morning is your best bet. Otherwise, it’s a waiting game.

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.
