The Lowdown
Alright folks, Rusty here with a look at the local surf scene. Gotta be straight with you – it’s a pretty flat and quiet stretch ahead. We’ve got one spot on the radar, Turtle Cove, but it’s a bit of a heartbreaker. The whole 16-day window is basically a long run of small, weak, or messy conditions, so don't expect any fireworks.
We start off with a couple of mornings of glassy 1ft waves on Friday the 14th and Sunday the 16th, but they’re paired with barely any energy – just 19 and 15 units of that combined swell energy – and the period is short at 9 seconds. It's the kind of stuff you'd paddle out on a foamie for a splash, not a real surf. The water temp is sitting at a warm 72°, which is absolutely normal for this time of year, so no surprises there.
There is a little bump on Monday the 17th. The swell pushes up to 6ft from the south, with a moderate 259 units of energy, but the period is a short 7 seconds and it's messy with a cross-shore wind. It’s marginal at best, and likely a bit too much for beginners at that size, but not really quality for anyone else either.
Then on Thursday the 20th, we see 5ft from the SSW with a clean cross-offshore wind in the morning. The energy is moderate at 163, but the period is still a weak 6 seconds. It’s surfable, but ordinary.
Looking into the second week, it’s more of the same. We get a small window on Saturday the 22nd with 6ft from the ENE, but it’s onshore and choppy, and that’s the biggest we see. The last real bit of interest is on Friday the 28th and Saturday the 29th, with clean offshore winds and a little 2ft swell coming from the SE. The period stretches out to 10 seconds on the Friday, giving it a bit of shape, and we see around 110 units of energy. It’s not a standout, but for this forecast, that’s as good as it gets.
Honestly, if you’re desperate for a paddle, those clean, glassy mornings with the tiny 1ft on the 14th and 16th might be your best bet, but don’t expect a wave you can really ride. The setup here isn't inspiring for a paddle surfer. For the most part, with the stronger onshore winds and mediocre swell, this coast looks more interesting for kite surfing than for us.
Stay tuned, things can change.
Rusty.

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.
