The Lowdown
Text 2 (Imperial)
Alright crew, let’s talk Turtle Cove. The water’s sitting at about 66°, which is a bit colder than normal for this time of year – a couple degrees cooler than average, so you’ll want a decent spring suit.
Honestly, the next week and a half is a bit of a write-off for any decent paddle surfing. We’ve got a long stretch of small, weak, and messy conditions. The wind is a real problem, mostly cross-off or cross, but it’s often strong – 18 to 28 mph winds – which just shreds up any chance of a clean wave. Through to the 19th, you’ll see tiny swell, mostly around 1 to 4 ft, but with really short periods (6-7 seconds). The energy is weak, bottoming out at 10 to 15. It’s not worth the paddle. There’s a bit of a bump on the 15th with 4 ft from the SW and a moderate offshore wind, but the period is only 7 seconds and the wave comment says it’s “ordinary conditions.” Not a standout.
Now, hold on, because things finally get interesting on the 20th. That Monday morning, the stars align a bit. We’re looking at 5 ft of swell from the ENE, but get this – glassy conditions. The wind is dead calm from the S at 3 mph. The energy jumps to 238 (moderate), and the wave comment says “expect good surf conditions.” This is your best bet for a clean, fun session, especially for intermediates. The swell direction is off the optimum SE, but with glass, you take what you can get.
Then, there’s a real red-letter day on the horizon. On the 25th and 26th, we’ve got more glassy mornings. The 25th sees 4 ft from the SSW, and the 26th builds to 5 ft from the S, with an 8-second period. Energy is strong (310-318) and the water will be glassy. The 26th morning is the true standout – 5 ft, clean, glassy, and solid energy. The direction is slightly off, but the wind is perfect. It’s a great prospect for a long session, but it’s a week and a half away, so keep an eye on it.
The rest of the run is mostly small and cross-shore. Not much to write home about. The 27th and 28th drop back to messy, weak surf.
So, take the wait for the 20th, or set your sights on that 26th morning.
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.
