The Lowdown
Alright, Rusty here. Let's check out what's on the menu for Turtle Cove.
Right off the bat, it's a bit of a slow start. The water's a touch cooler than usual for this time of year, sitting at about 68°, so maybe grab a slightly thicker suit if you're feeling the cold. The first few days are a write-off, with tiny, weak swells and messy wind. We're talking Thursday the 16th through Saturday the 18th with nothing worth paddling out for. It's a bit of a waiting game.
Now, the first real glimpse of hope comes on Sunday the 19th. The morning session is the standout from the early part of the week. We've got a solid 6ft swell pushing in from the SSW, with a moderate 8-second period. The energy is moderate (407), and with a clean offshore wind from the W, it'll be a lot better than what we've seen. This is a proper window for it.
Monday the 20th is the pick of the whole outlook, in my opinion. The morning is glassy, dead calm with a light SW breeze. The swell drops a touch to 4ft from the S, but that's plenty for a fun session. The energy is still moderate (211), and with that glassy surface, the waves will be clean and smooth. Get on it early before the sea breeze picks up and messes it up by the afternoon.
The week after that is a mixed bag. Wednesday the 22nd offers another decent shot in the afternoon with a 6ft SSW swell and a clean offshore WNW wind, that's a solid session (energy 390). The following Saturday the 25th morning shows some promise too, with a gentle offshore and 4ft swell from the SE. The energy is moderate (317).
As we move into the second week, things get a bit more up and down, but there's still a pulse. Sunday the 26th morning has a bigger 7ft SSW swell with moderate energy (718), but the wind is a cross-off. It's a big one for more experienced surfers. The last few days of the month and into the 31st don't show much quality, with onshore winds and lumpy conditions, so don't get your hopes up for that stretch.
Overall, your best bet is the glassy morning of Monday the 20th. Sunday the 19th morning is also a strong call. Get out there and enjoy it.

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.
