The Lowdown
G’day, Rusty here. Let’s be straight with you—this isn’t exactly a banner period for Turtle Cove. The first few days have some rideable waves, but nothing to write home about. After a quiet start, there’s a bit more energy around the second weekend, but the winds are often messy. Let’s run through it.
We kick off Friday morning, August 7th, with a weak pulse. Swell is 3ft from the SSW with a short 6-second period—lots of push but no grunt, combined energy sitting at just 57. The water’s a bit colder than average for this time of year at 70°. Morning looks best with a clean cross-off breeze from the WSW, 9 mph. It’s surfable but very ordinary. Afternoon goes downhill fast—wind jumps to 15 mph from the SSW, swell drops to 1ft, and it’s a write-off.
Saturday the 8th is a similar story. Morning offers 3ft SSW swell with a 6-second period, and this time offshore WSW wind at 12 mph keeps it clean. Combined energy is 82—still weak. Afternoon—again, wind picks up and the swell fades. Sunday the 9th morning is the pick of the first three days: 3.6ft from the SSW, 6-second period, combined energy of 96, and offshore W wind at 12 mph. Clean, but still just small and weak.
Monday morning August 10th brings the first real highlight. Glassy conditions—SE wind at just 3 mph, flat calm. Swell is 2.6ft from the SSW, period 6 seconds, energy 55. It’s tiny but it’ll be silky smooth. About as good as it gets for the size.
After a midweek lull with mostly poor conditions and tiny waves, the next standout lands on Sunday morning August 16th—except that morning has 18 mph SSW cross-off wind and almost no swell (0.3ft). The afternoon is where it gets interesting: 4.9ft from the S on a 6-second period, combined energy of 135—moderate. Wind is cross-off from the WSW at 15 mph, so it will be clean but a bit bumpy. That’s a solid size for Turtle Cove, but with that short period it’ll be a bit crumbly. Still, it’s the biggest wave of the period.
Monday August 17th morning builds on that: 4.3ft from the SW, 6-second period, energy up to 168—moderate energy. Cross-off NW wind at 15 mph keeps it clean. The afternoon is even cleaner with gentle offshore WNW wind at 9 mph, and the same 4.3ft swell. This two-day window from Sunday afternoon to Monday afternoon is the best on offer—biggest swell, moderate energy, and decent winds.
Tuesday August 18th morning is a glassy, small session with 2.6ft from the SSW, 7-second period, energy 78. Clean but small. After that, the forecast fades into tiny, weak swells with inconsistent periods and mostly cross-off winds through to the 22nd.
Overall, Turtle Cove is a reef and point set-up that’s fairly consistent, but over this 16-day window the waves are rarely above knee-high with any real power. The best call is Sunday August 16th afternoon through Monday August 17th, when the swell pushes to chest-high and the energy is moderate. Expect clean conditions but short-period waves that won’t hold a long wall. Crowds are possible on the better days—it’s a spot that can get busy when it’s good. If you’re a beginner, Sunday the 16th at 4.9ft might be a bit much; stick to the Monday morning glass-off for smaller, cleaner waves.
Stay keen, but don’t expect a classic.

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.
