Table - best surf conditions forecast for Turtle Cove over the next 16 days.
Alright Rusty here, let’s break down Turtle Cove the old way.
Gonna be a tough couple of weeks, no two ways about it. Most days are small and chopped up, with a lot of flat spells. The first real shot at a wave is Friday the 17th of July, but it’s nothing to write home about. The one you really want to save for is Saturday the 25th of July.
From now through the 16th, it’s a write-off. Swell is mostly under 2ft, wind is messy, and the water is 18° – that’s 3° colder than it should be, so bring a thick wetsuit to Turtle Cove.
Friday the 17th morning you get a 4ft SSW swell with moderate energy – about 110 – and a light cross-off breeze from the NW, so it’ll be clean but ordinary. Afternoon pushes to 4ft with stronger energy at 178, but the SW wind picks up to 25 km/h, so it’s not prime.
Then it’s flat again until the 22nd. On Wednesday the 22nd of July, the afternoon brings the goods: a 5ft east swell with solid energy at 283, and a light cross-off breeze from the SSW. That’s clean and the first real standout.
But the best is Saturday the 25th. Morning you get a 4ft south swell – right in the sweet spot for Turtle Cove – with a gentle offshore wind out of the WSW. Energy is 245, and the comment says “expect good surf conditions.” That’s your session. Afternoon holds at 4ft but the wind goes cross-off, so still fun.
Crowds are only “sometimes” a problem, and the break is fairly consistent. On that Saturday morning, you might have it pretty quiet with that offshore glass.
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.
