Table - best surf conditions forecast for Turtle Cove over the next 16 days.
G’day, Rusty here. Look, I’m gonna level with you – this Turtle Cove outlook is a tough one. The next two weeks are mostly a write-off for decent waves. The water temp is sitting at 67°, which is a bit colder than normal for this time of year, so you’ll want a decent wetsuit if you’re even thinking about getting in.
We’ve got a big gap of nothing really surfable from now until the middle of the month. Thursday the 9th is tiny, weak, and messy with a cross-off breeze. Friday the 10th morning has a slight pulse—3 ft from the SSW, short period (6 seconds), with light offshore wind—but the energy is still weak (66) and the conditions are “ordinary.” It’s barely a ripple.
That same pattern drags on. Saturday and Sunday are cross-on or onshore junk. The whole first week is just a bunch of poor surf with weak energy readings, mostly under 100. Monday the 13th through Wednesday the 16th all have clean enough conditions, but the swell is tiny, never breaking 2 ft. It’s depressing.
Now, there is a little glimmer right at the end of the window. Sunday the 19th morning stands out as the best on offer. We’ve got a 5 ft SSW swell (period 7 seconds) with a light cross-off breeze from the WNW. The combined energy jumps to 292 (moderate), and the forecast actually says “expect good surf conditions” with a score of 2. That’s the only decent session in the whole 16 days. The afternoon of that day drops off again with bigger wind and poorer conditions.
Monday the 21st morning sees a bigger pulse—6 ft from the SSW with an energy of 591 (strong)—but it’s cross-on wind and the forecast says “marginal.” That’s expert-only territory with the size, and the wind is ruining it. After that, it’s back to small, clean but gutless waves for the rest of the forecast.
So, to sum it up: if you’re desperate, point your car at Turtle Cove for the morning of Sunday the 19th. It’s the only real standout. Everything else is a skunk.
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.
