The Lowdown
Alright, let’s talk about Turtle Cove. We’ve been in a drought for a while, and it’s not looking good to start.
Right now, through the weekend starting Friday the 24th, it’s a write-off. Swell is tiny, wind is all wrong—onshore or cross-on—and the water is sitting at 67°, a solid 4° colder than average. That’s a real chill. There’s no reason to wax up.
This flat spell stretches all the way through to the end of the month. The first real flicker of hope comes late Monday the 29th, but it’s the following day that’s the deal. Wednesday the 30th has a standout session in the morning. You’ve got a 5ft swell from the NE, a short 6-second period, but the wind is blowing offshore from the west at 9 mph. The wave energy is moderate at 377. It won’t be world-class, but it will be clean and fun for the average surfer.
Thursday the 31st is the best day on offer. The morning has a clean 5ft NE swell with that same short period and a gentle offshore breeze from the west. The waves will have some shape. By the afternoon, the swell drops to 3ft from the SSE but the period stretches to 10 seconds, which means a better, more powerful wave, and the wind stays light and offshore. It gets glassy. That’s your window.
Into the first week of August, we get a bump on Thursday the 6th. The morning brings a 7ft SSW swell with a short 6-second period, but a solid 20 mph offshore wind. The energy is moderate (328). That’s for the experienced crew, as the size and short period can make for some tricky, fast walls. The afternoon pushes it to 7ft (407 energy). For everyone else, the previous weekend is a better bet.
By Friday the 7th, it drops to 4ft and goes glassy. A nice, clean option for a relaxed session. Then the weekend of the 8th, the plug is pulled. It’s tiny and windy.
So, to sum it up: don’t bother until Wednesday the 30th. Thursday the 31st is your top call for clean, consistent, fun waves. After that, you’re gambling on a bigger, more challenging swell on the 6th. Keep your eye on the wind.

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.
