The Lowdown
Alright folks, Rusty here. Let’s get stuck into the outlook for Turtle Cove. We’ve got a 16-day window but don’t get your hopes up too early—it’s a rough start.
The first few days are a write-off. Monday the 3rd sees a solid 10ft southerly swell, but it’s getting hammered by near gale-force cross-off winds and the energy is pumping (1331). That’s not surfable, it’s a washing machine. The setup looks more interesting for kite surfing than paddle surfing.
We finally get a real window of opportunity on Tuesday morning, the 4th of August. It’s the standout of the whole period. The swell drops to a clean 5ft from the south, and the wind goes glassy—dead calm from the northwest. That’s a major positive. The wave energy is moderate (234), and those conditions will make for some clean, lined-up waves at this reef and point. It’s a fairly consistent spot, and crowds are possible, so get in early. The water temp is about average for the time of year.
After that, Wednesday the 5th is a mess. Heavy rain, a 5ft swell but with a cross-onshore wind and chop. Thursday the 6th and Friday the 7th stay small but keep getting blown out by fresh cross-off winds. The swell sticks around 4ft to 5ft, but the wind is just too strong.
Saturday the 8th morning offers a tiny 3ft south-southwest swell with a light offshore breeze—clean, but very ordinary. That’s the last decent window for a while.
From Sunday the 9th all the way through to Sunday the 16th, it’s a long flat spell with small, weak swell and poor conditions. The combined energy dips to under 100 (weak), and the wind is mostly fresh or moderate. The only bright spot is Tuesday the 11th morning with a 3ft swell and a moderate offshore wind, but it’s still just surfable, not exciting.
The second week picks up a tiny bit on Saturday the 15th with a 5ft south-southwest swell and moderate cross-off wind, but the energy is only moderate (200) and the quality is marginal. Nothing to plan a trip around.
So, the true standout is Tuesday morning, the 4th of August. Glassy, clean, and a solid 5ft. Get it while it lasts.

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.
