The Lowdown
Alright folks, Rusty here, giving you the lowdown on what's shaking at Turtle Cove.
We're looking at a pretty bleak stretch up front. The next week is gonna be a real test of patience. There's some tiny swell around, but the wind's mostly working against us or it's just too damn small. Water temp is sitting at 70°, which is bang on average for this time of year, so no surprises there. We're looking at a solid gap of several days before anything worth paddling out for shows up.
Honestly, the only time this place gets a pulse is around Wednesday the 9th to Thursday the 10th. On Wednesday afternoon, a south-west swell pushes up to 7ft with a 7-second period. The combined energy kicks up to a solid 421 (moderate wave energy), and with a clean cross-off breeze, those waves will be proper. That's the standout, no doubt. It's a bit of a jump in size though – at 7ft, it's getting into expert-only territory for a lot of folks, so keep that in mind. The wave quality should be there.
Leading into Thursday morning the 10th, it drops back to 5ft, still from the south-southwest. The combined energy is still decent at 235, but there's a moderate cross-off breeze again, so it should be rideable for the more experienced intermediate crew. It won't be as clean or as powerful as the Wednesday arvo, though.
After that little bump, it fades fast. The last week of the outlook is back to small, weak dribble, with the odd clean wind but no power behind it. For the last day around the 17th, there's a brief window of super small 1.0ft swell with a long 13-second period, but there's just no water moving to make it worthwhile.
So, for the whole 16-day window, your best bet is Wednesday afternoon, the 9th. Get on it if you're hungry for it. Everything else is a scratch around or a flat spell.

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.
