The Lowdown
Alright, Rusty here. Let's have a look at what's cookin' for Turtle Cove.
Right off the bat, the water is sitting at 68°, which is a bit colder than we'd expect for this time of year – about 3° off the mark. So, you might want an extra layer if you're heading out.
The next 16 days are a real mixed bag, but it's not all doom and gloom. We've got a couple of promising windows if you're patient.
The first half of the week is a write-off. Saturday and Sunday are a no-go, with tiny swell and messy winds. There's a bit of a pulse coming in on Sunday afternoon with a 4ft SSW swell, but it's a short-period 7-second wind swell, so it's not going to be anything special. The wind is offshore, which is a positive, but the energy is just not there.
Monday morning, the 20th of July, is a real tease. We've got glassy conditions with a 3ft SSW swell, but it's still weak energy (107). It's surfable, but you'll be working for it.
The first real standout is Wednesday, the 22nd of July. We're looking at a solid 8ft SSW swell, with a period of 9 seconds, and a massive combined energy of 1057. That's a lot of water moving around. The wind is cross-off, so the waves will be clean. Now, this is a beefy swell. Over 8ft, this is expert territory. If you're not comfortable in heavy, powerful surf, give this one a miss. For the experienced crew, this is the one to circle.
Thursday the 23rd of July holds some good size too. The morning session is looking best with a 5ft S swell and offshore winds. The energy is still strong (447), and the conditions should be clean. The afternoon drops a little, but still has some punch.
After that, we drop back into a long stretch of small, weak surf. The wind is often onshore or cross-shore, making for choppy, poor conditions. There's a flicker of hope on Monday the 27th of July with a 4ft S swell and clean conditions, but the energy is only moderate (203), and it's not a world-beater.
Then, on Tuesday the 28th of July, we get another interesting window. The afternoon shows a 3ft S swell, but with a 10-second period and a moderate 217 energy, with offshore winds. It's a solid, clean option for a late session.
The rest of the forecast, right through to the 2nd of August, is a flat, windy mess. Swell is small, and the wind is mostly onshore or cross-onshore, ruining any chance of a decent wave.
So, the standout is absolutely Wednesday, the 22nd of July, for the big-wave experts. For the rest of us, Thursday the 23rd of July morning is the best bet for a clean, manageable wave. The rest of the period is a write-off unless you're a kitesurfer, because that big swell on the 22nd and 23rd with strong cross-off winds makes for a much better kite setup than a paddle one.
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.
