The Lowdown
Alright crew, Rusty here again, this time in feet for you. Let’s break down Turtle Cove. It’s a quiet outlook overall, with a lot of flat and blown-out days in the 16-day window.
The first real recommendation isn’t until Saturday, September 26th. Before that? Forget it. Days of onshore gales, tiny chop, and swell under 3ft. You’ll be paddling in place, not surfing. There’s a brief moment on the 13th with light wind, but the swell’s barely 1ft. Not worth the drive.
Now, Saturday morning, September 26th at Turtle Cove (a reef and point break). This is it. It’s clear skies, glassy wind from the SSW at only 5 km/h. Swell is 5ft from the ESE, period 7 seconds. Combined energy is moderate (236). This is a clean session waiting to happen. That offshore glass will groom the waves nicely. The water temp is normal for this time of year. Crowds are possible here sometimes, so get there early. For beginners, 5ft is manageable, but respect it if you’re new. For the rest of you, it’s a solid fun size.
Sunday the 27th of September morning also has 4ft from the ESE, but the wind is a cross-off 30 km/h. It’ll be cleaner than most days but not as good as Saturday. The energy bumps up a little (347), but the wind drops the quality.
After the 27th, it’s back to small, wind-affected junk. The next few days don’t look promising.
Best advice: circle Saturday the 26th of September morning on your calendar. That’s your one real chance in this outlook. Everything else is a swing and a miss.
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.
