The Lowdown
Alright, listen up. Water's 73°, right about average for this time of year. We got a solid run of SW swell coming in, but it's not gonna be a walk in the park. You gotta be picky.
Sunday morning is your first go-to. Swell's a clean 6ft from the SW with a long 15-second period. That's proper groundswell. Light offshore east wind, so it'll be clean and glassy. This is Turtles (Big Island), an advanced spot, and it's handling the energy well. The combined energy is strong at 1563. This is the standout early call. For the experienced crew, this is the one. The afternoon goes a bit onshore and it loses its shine.
Monday is a skip. Cross-shore winds pick up to 15-18 mph and it'll be choppy. Not worth it for that 5ft of swell.
Tuesday bounces back. The morning is clean with light NE cross-off winds and a 4ft WSW swell with a long 16-second period. Not huge, but fun. Then the afternoon is where it's at – the swell bumps to 5ft and the period stretches to a very long 19 seconds, with a light offshore east wind. That's a proper session, clean and powerful. Energy is moderate at 1779, but quality is high.
Wednesday brings a step up in size. 8ft of WSW swell in the morning, but the SE cross-off wind will keep it a bit raw. It's getting big, so it's for the experienced. The afternoon gets more ragged with a cross-shore wind.
Thursday is when it pushes hard. The morning has a solid 10ft of WSW swell, but a cross-shore SSW wind will make it lumpy. The energy is strong at 3973, but the quality is marginal. The afternoon is a total loss with strong cross-onshore winds. Don't bother.
Friday is a step down but the wind is still messy. Cross-shore winds from the south will keep things grovelly. The 7ft of swell will be there, but it won't be pretty.
Saturday morning is a big one. Strong cross-offshore winds from the SE at 25 mph with a 8ft SW swell. It'll be big, powerful, and blown. The energy is strong at 2450. This is for the chargers. The afternoon sees the swell jump to 10ft, and while still cross-off, the wind backs off a touch to 18 mph. Big, raw, and for experts only.
Sunday the 9th is interesting. Strong cross-off ESE wind at 18 mph with a solid 8ft SW swell. Big and powerful, but with that wind, it's going to be an intense session. Strong energy at 3422.
Monday the 10th is a no-go. Cross-onshore winds and the quality just tanks. Same for Tuesday the 11th – the winds get even stronger and the swell drops, so it's a blank spot.
Wednesday the 12th is still messy. Not worth it.
Thursday the 13th looks promising. The swell is back up to 8ft from the SW with a 16-second period, and we get strong cross-offshore SE winds. It's going to be big, clean, and powerful. Strong energy at 3034. Another one for the advanced crew.
Friday the 14th is the next real standout. The morning has 7ft of SW swell but the wind goes fully offshore from the ESE at 21 mph. That's a clean, powerful wave. The energy is at 2271. This looks like a great day. The afternoon is still clean, but the wind eases to a cross-off.
Saturday the 15th is also looking good. Morning has a fresh offshore E wind at 18 mph with a 6ft SW swell. Clean and lined up. The afternoon is similar with a WSW swell holding at 7ft but the wind is a bit softer.
After that, into Sunday the 16th and Monday the 17th, the swell starts to fade. The size drops and the winds stay strong but the energy weakens. It'll be the dying days of this swell.
So, the two standout sessions are Sunday morning and Friday the 14th morning. Both have quality SW groundswell with offshore winds. The first has a longer period, the second is a bit bigger and windier. Both are for experienced surfers. Don't sleep on the Tuesday afternoon either; that long-period swell is a treat.
Keep it salty.
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.
