The Lowdown
Well, folks, it’s another quiet stretch here at Turtle Cove. The whole 16-day window is looking pretty flat and messy, so don’t get your hopes up for any real waves. This is one of those rare runs where it’s just not happening.
We start off on Sunday, 26 July, with a small 4ft E swell pushing in, but it’s got a short period of only 7 seconds. The wind is a cross-on from the NE at 9 mph, and the water is a bit colder than normal at 68°. The combined energy is weak (255), and the surf is poor. Nothing worth paddling out for.
Monday, 27 July, brings even smaller waves – 2ft SE swell with a 7-second period. The wind stays cross-on from the ESE at 6 mph, and the energy drops to 72. Still poor.
Tuesday, 28 July, the wind picks up to 16 mph from the SSE, making it choppy with a 3ft SSE swell. Energy is 85. Still poor.
Wednesday, 29 July, we see a spike in energy to 181 with a 5ft SSE swell, but the period is a dismal 4 seconds. The wind is onshore from the ENE at 16 mph, and there’s light rain. The combined energy climbs to 353 in the afternoon, but it’s still poor surf. It’s going to be a lumpy, choppy mess.
Thursday, 30 July, the swell hangs around 4ft to 5ft from the SSE, period 8-9 seconds, but the wind is fresh cross-on from the NE and NNE, up to 22 mph. Energy is moderate (334-368). Still poor.
Friday, 31 July, the swell drops to 3-4ft, period 8-9 seconds, with cross-on winds from the NNE and NE. The afternoon session gets a 1 out of 10 for marginal conditions. The energy is 204-292. Still not worth it.
Saturday, 1 August, glassy conditions in the morning – calm wind, 3ft S swell with a 9-second period, energy 131. The waves are surfable but very ordinary. The afternoon turns cross-off from the SSW at 16 mph, cleaning it up, but the swell is dropping to 3ft. It’s a small, clean wave, but nothing to get excited about.
Sunday, 2 August, tiny 3ft S swell, 7-second period, winds are light cross-off from the SSW. Energy is 74. Poor.
Monday, 3 August, the morning looks glassy with a 3ft S swell, 8-second period, energy 128. Surfable but very ordinary.
From Tuesday, 4 August, through to Saturday, 8 August, the swell is tiny – 1ft to 3ft, mostly from the S or E, with periods from 6 to 9 seconds. Winds are mostly cross-off, keeping the surface clean, but the energy is weak (44-85). The afternoon of Friday, 7 August, gets a 1 out of 10 with a gentle offshore wind from the WSW, but the waves are only 2ft.
Sunday, 9 August, a new 4ft SSW swell arrives with a 6-second period, but the wind is onshore from the E at 9 mph. Energy is 112. Poor.
Monday, 10 August, the last day in the window, sees onshore winds from the ESE and ENE at 19-22 mph, with tiny 2-2ft SSW swells. Energy is 30-49. Poor.
The best on offer is the glassy morning of Saturday, 1 August, with a 3ft S swell, but it’s still very ordinary. The most promising is the morning of Monday, 3 August, with a clean 3ft S swell, but it’s still just a marginal wave. Nothing here is a standout.

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.
