The Lowdown
Alright, Rusty here. Let's have a look at what's on the menu for the next couple of weeks.
First thing you need to know: the water is sitting at a pretty chilly 68°, which is a bit colder than it usually is this time of year. So you'll want a good thick suit if you're heading out to Turtle Cove.
Honestly, the start of this period is a real struggle. We've got a tiny 0.3ft swell on Saturday the 18th with a stiff 30 mph cross-offshore wind, and it's just poor. That carries on into Sunday morning with a 4ft swell but a messy 7-second period. The afternoon of the 19th finally gives us something to talk about: a clean 4ft swell from the SSW with a nice 12 mph offshore wind. It's surfable, but the conditions are still pretty ordinary.
Now, Monday the 20th is where it gets interesting. The morning is a beauty: glassy conditions, 3ft of swell from the SSW, and the wind is dead calm. That's about as clean as it gets, but the swell is small and the period is short at 8 seconds, so it's not going to have much push. This is the best of a quiet bunch, but it's not a standout.
The rest of the week is a write-off. Tuesday the 21st has onshore winds and lumpy, choppy conditions. By Wednesday the 22nd, we get a spike in energy with an 8ft SSW swell, but the wind is a strong cross-offshore. The combined energy is solid (867), but the tides and conditions are questionable. That swell is too big for beginners and the wind is not ideal. Thursday the 23rd is a bit smaller at 7ft, but still messy with cross-shore winds.
The second week is mostly a washout. We get a few glassy moments on the 30th of July with a 5ft swell, but the period is only 6 seconds from the east, so it's weak and crumbly. The rest of the time it's either onshore, chop, or just tiny surf. The gap from the 24th of July through to the 2nd of August is a long stretch of poor options with no real window of quality.
If you're looking for the one true standout, it's Monday morning, July 20th at Turtle Cove. The 3ft glassy conditions with that clean offshore wind will be a rare treat, but keep your expectations low on size. The only other moment of note is Wednesday the 22nd if you're an expert looking for a bigger, more powerful wave, but the wind is a problem.
So, to sum it up: we've got a couple of fleeting windows, but nothing that's going to have you calling in sick. Keep the board waxed for that Monday morning glass-off.
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.
