The Lowdown
Alright, Rusty here. Let me tell you what's cooking, or more like *not* cooking, at Turtle Cove.
Right off the bat, I gotta be straight with you: the next couple of weeks are looking pretty grim. We've got a long dry spell ahead. The first nine days are basically a washout, with nothing worthwhile to even get wet for. It's a tough stretch.
Saturday, September 5th kicks it off with tiny 1ft dribbles from the SE and a cross-on wind. Not much to say there. We get a bit of a reprieve on Sunday afternoon, September 6th, with some clean conditions and a light cross-off breeze, but the swell is a pathetic 2ft. The waves are just too small to do anything with.
The pattern holds through the week – tiny waist-high-or-less slop. On Monday, September 7th, we see a 1ft easterly swell with some clean, offshore wind in the afternoon, but that 10-second period is just not pushing enough juice. The wave energy is weak, barely cracking 26. Wednesday the 9th gets a bit spicy in the afternoon when a 7ft SW swell rolls in, but it's short period at 6 seconds and the wind is howling at 28 mph. That's a messy, blown-out mess. The energy jumps to 309, but the quality is zero. Then Thursday, September 10th brings the biggest swell of the run, a 6ft SSW pulse with a strong offshore wind. Sounds good, right? The problem is the wind is so strong (25 mph) it's actually making it really hard to paddle into anything. The wave comment says it all: "strong offshore and clean but hard to paddle into."
After that, it’s back to the tiny stuff. We get a glassy morning on Saturday, September 12th – a glimmer of hope – but it's on 1ft surf. You could almost hear a pin drop.
The only time we get a whisper of a "surfable" wave is on Friday, September 18th in the morning. A 3ft SE swell with a moderate offshore wind. The combined energy is 63, and the comment calls it "surfable waves but very ordinary conditions." That's the best of a bad bunch, but it's still a low-energy day.
So, to sum it up: the surf is tiny for the entire 16 days. There is no standout, no day to circle on the calendar. It's a real bummer. For an exposed reef and point like Turtle Cove, the setup looks more interesting for a kite than a paddleboard for most of this period. The water temp is about average for this time of year, so no surprises there.
Stay patient. It tends not to stay this poor 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.
