The Lowdown

Alright folks, Rusty here. Let’s look at the window ahead. It’s a bit of a mixed bag for us, with some real shine early on and then a whole lot of chop and wind to fight through. The surf isn’t going to be a total no-show, but you’re going to have to pick your moments, especially as we get deeper into the forecast.

The standout window is looking like Thursday the 10th. We've got a decent SW groundswell running, and for a moment there, the conditions line up to make it worthwhile. The wind is set to go light offshore in the morning, which will be a godsend for keeping things clean. That's the one to circle on the calendar. The swell will be around 6ft, and with that offshore flow, Turtles (Big Island) should have some proper shape to it. The energy in the water is still strong, with a combined swell energy reading of 1439, and that long 15-second period means there’s some real push behind it. This is a session for experienced surfers, though—the size and power are nothing to mess with if you're still learning the ropes.

Before that, Tuesday the 8th and Wednesday the 9th are going to be a washout. The swell is up around the 8ft mark, but we have a fresh cross-offshore breeze that will just put a texture on the face, and the call is for marginal surf. It’s not going to be pretty. We’ll see energy readings around 2484 and 4246, but that’s all for nothing when the wind is howling. You'd be fighting it more than surfing it.

After Thursday’s brief moment of glory, the wheels come off a bit. The wind swings onshore and stays there for a while. We're looking at a good run of days with cross-onshore and cross-shore winds, making things choppy and lumpy. The swell stays in the 5ft to 7ft range, but the quality just isn't there. Friday the 11th looks poor, the weekend is a write-off with increasing wind, and into the following week, it's more of the same. Monday the 14th and Tuesday the 15th have some size on offer, but it’s all blown out with fresh breezes and a messy cross-chop. The energy remains moderate, but the conditions will have you fighting just to stay in position.

We get another glimmer of hope late on Friday the 18th morning. The wind is due to drop off, and the swell is around 6ft, but it’s looking light and cross-onshore. It might be cleaner than the rest of the week, but it's still not the clean offshore we had on the 10th. Then we’re back into choppy, lumpy territory with fresh winds and no real let-up. The last few days of the window, from the 20th into the 23rd, are a mix of poor and marginal conditions. There’s size by the 23rd—up to 8ft—but a strong cross-offshore breeze will be blowing. That’s a hard pass.

All in all, the main event is Thursday morning. Get on it if you can. After that, it’s a waiting game for the wind to play fair again, which it doesn't look like doing for a while. A blank run is more normal for this area when it gets like this. Keep the faith, though. It’ll come back around.

Rusty.

Information about the Turtles Surf forecast

The above surf forecast table for Turtles provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Turtles can be found by selecting the local surf guide option on the grey menu. Our Turtles 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 (Turtles) 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 Turtles 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.
