The Lowdown
Alright, Rusty here. Let’s have a look at what’s on offer.
Right off the bat, I gotta tell ya, it’s a pretty flat and quiet run ahead for Turtle Cove. The first bit of the week doesn’t give us much to work with. We’ve got a few small windows of surfable but very ordinary conditions, but nothing that’s gonna get your heart racing. The energy is just not there, with combined swell energy in the low double digits for most of it.
Wednesday morning, the 26th of August, is about as good as it gets early on. We’re looking at a clean 2ft swell from the ESE, with a light offshore breeze from the west. It’s small, but the surface will be clean, so if you’re desperate for a splash, you could scratch something out. The combined energy is only 53, so it’s weak.
The pattern stays pretty lackluster through the rest of the week. Friday morning the 28th has a similar 2ft ESE swell, but with a light cross-off breeze. The combined energy ticks up to 102, which is at least moderate, but the waves are still unremarkable. The wind stays clean, but it’s a struggle to get excited.
There’s a bit of a gap with no real recommendations after that until Wednesday afternoon, the 2nd of September. That afternoon sees a 2ft SE swell, period stretching to 11 seconds, and a clean cross-off wind from the southwest. The combined energy hits 128, which is moderate. This is the best looking window in the whole run, but it’s only a small, clean bump.
The beginning of September brings a short-lived pulse of bigger swell. Thursday morning, the 3rd, we see a 4ft swell from the NE, but the period is a short 5 seconds and the wind is onshore. The combined energy is 137, but the quality will be poor, messy and lumpy. Not one for the paddle surfer, might be more interesting for the kite crowd.
After that, it fades back into small, clean but weak conditions for the second week. The water temperature is about average for this time of year, nothing unusual to report.
Honestly, the standout in this whole 16-day window is that Wednesday afternoon, the 2nd of September. Turtle Cove is a reef and point, so it handles that southeast swell direction well. The wind is clean, the combined energy is at its highest, and it's the only time the conditions really line up. It’s not a classic, but it’s your best bet.
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.
