The Lowdown
Alright folks, Rusty here. Let's get into the outlook for Turtle Cove.
Right off the bat, I gotta be straight with you – it's a tough stretch ahead. We're looking at a long, dry spell for most of the next 16 days. There's a big gap of nothing much happening until we finally see a glimmer of hope right at the tail end. The first few days are a write-off, and we're basically waiting over a week for something that's barely surfable.
The water temp at Turtle Cove is sitting at about 72°, which is pretty average for this time of year, nothing unusual there.
The first real sniff of something happens around Monday, August 24th. We get a little bump in the afternoon with swell from the SSW pushing 4ft, but it's a short-period 6 seconds and it's getting hammered by a fresh 19 mph cross-offshore wind. It's clean but messy and weak. The combined energy is moderate (167), but honestly, it's not calling my name. The WSW wind on the Monday morning is a better look with a clean 3ft wave (energy 110), but it's still tiny and weak.
Tuesday, August 25th brings a fresh 19 mph offshore wind from the W, which would make the ocean look like glass. The problem? The swell is tiny at 1.0ft with a long 11-second period from the SE. It's clean but there's just no push. It's more of a paddle than a surf.
After that, the forecast flatlines again. There are days with clean conditions but the swell is just too small to do anything on. The wind goes onshore and the waves get choppy. The only time we see any decent energy is on Thursday, September 3rd. The morning shows a 4ft swell from the SE with a 10-second period, and the combined energy jumps to 200. But the problem is a strong 16 mph cross-onshore wind from the ENE, making it choppy and ugly. This is a classic case of a beach break getting blown out.
Friday, September 4th morning might be your best bet if you're desperate. The wind goes glassy, dead calm, with the swell from the ESE at 3ft and an 8-second period. The combined energy is a moderate 102. The waves are surfable, but they're very ordinary. It's clean, but it's not going to be a standout session.
Then we get another gap. The very last day, Sunday, September 6th, shows a pulse of swell from the S at 3ft with an 11-second period. But the wind is a full-on 16 mph onshore from the ESE, with combined energy at a strong 228. For a reef and point break, this is going to be a bumpy, blown-out mess.
Honestly, for this 16-day window, there's no true standout. The combination of tiny swells, wrong wind directions, and long gaps of nothing makes this a period to keep the board in the car and maybe go for a swim. The only time the stars nearly align is the morning of September 4th with that glassy wind, but the swell is just too weak to get excited about. Keep an eye on the charts, though, because it tends not to stay this quiet for long.
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.
