The Lowdown
Right, let’s have a look at what’s on offer. Straight up, it’s a pretty grim run for the next 16 days around here. Turtle Cove (reef and point) is the only break in the mix, and the opening stretch is a write-off. You’re looking at a solid block of nothing – from now until the morning of Saturday the 22nd of August, there’s basically no surf worth paddling out for. The combined swell energy is weak, mostly hanging around double digits (36) or even single digits, and the swell heights are tiny, mostly under 3 ft. The wind is clean on plenty of mornings, but there’s just no push behind it.
The first real glimmer of hope doesn’t show up until Saturday morning, the 22nd of August. That’s a long gap. The wind goes glassy, which is a major positive – clean conditions. The swell is still only 3 ft from the SE, with a period of 12 seconds, so it’s a long-period groundswell. That’s a bit of a double-edged sword at a point and reef setup like this: it’ll bring some shape, but the sets will be spaced out. The combined energy climbs to 239 (moderate). It’s the best call in the whole window, but it’s a long way off and a bit of a gamble. Still, if you’re desperate, that’s your window.
Sunday the 23rd of August morning sees a jump in size to 7 ft from the S, but with a short period of 6 seconds, it’s going to be a lumpy, weak mess. The wind is cross-off, but that size and period combo is more interesting for the kite crowd than for a standard paddle session. The energy is strong (328), but the quality won’t match the numbers.
The water temperature is about average for the time of year, nothing unusual to report.
So, to sum it up: the 22nd of August morning is the only real standout, and it’s a distant one. Hold tight, and check back closer to the time.

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.
