The Lowdown

Alright folks, Rusty here. Let’s get into it. We’ve got a long stretch ahead at Turtle Cove, and honestly, it’s a bit of a mixed bag. The water’s sitting at about 68°, which is a touch colder than we’d expect for this time of year – about 3° off the norm, so you’ll feel that chill.

The first few days are a write-off. Saturday morning (18th July) is a complete dud with basically no swell to speak of – just 0.3ft, and the energy reading is a paltry 10. That’s weak, flat, and not worth a second look. The whole weekend is similar; there’s nothing happening until Sunday afternoon (19th July) when a little pulse of 4ft swell from the SSW shows up, but it’s a short-period 7-second wind swell, and the wind is offshore. It’s surfable, but it’s ordinary. The energy is only moderate (178).

Now, Monday morning (20th July) is where we finally get a *little* something. The swell drops to 3ft from the south, period is still short at 8 seconds, but the wind goes glassy. That’s the big positive. It’s not going to be a world-beater, but with clean conditions, you might find a few fun ones. The energy is weak to moderate (135). Still, it’s the best thing on offer for a while.

We hit a proper lull for a few days. Tuesday and Wednesday (21st-22nd July) are all cross-onshore junk and poor surf. But then look at Wednesday morning (22nd July). The swell jumps to 12ft from the SSW, with a 10-second period – that’s groundswell, and the energy reading is a massive 1966. That’s strong, powerful stuff. The wind is cross-offshore, so it’ll be clean. But make no mistake, at 12ft, this is for experts only. Beginners should stay well clear. The afternoon drops to 8ft, still heaving, still strong (2181 energy). This is your standout. It’s beefy, it’s powerful, and it’s going to be a proper session for the experienced crew.

After that, it backs off quickly. Thursday (23rd July) is still 6ft from the south in the morning, but the wind is cross-on, so it’s lumpy. The energy is still moderate (668), but the quality is gone. Then it’s back to small, weak, and mostly poor surf for the rest of the forecast. The glassy mornings on Tuesday 28th and Wednesday 29th July offer tiny 2-2ft waves, but they’re barely rideable. There’s a bit of a bump on the 31st July and 1st August, but it’s short-period wind swell with onshore winds – not worth the trip.

So, the big call is Wednesday 22nd July. That’s your one true standout. A solid, powerful SSW groundswell with clean wind. It’s a week out, so keep an eye on it, but if you’re a confident surfer, that’s your window. The rest of the 16 days is mostly a waiting game with a lot of flat spells.

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.
