The Lowdown
Alright, Rusty here. Let's get into it.
We've got a window opening up, but it's a mixed bag. The main event is Turtles, a heavy, advanced reef break. This one is exposed and picks up a good SSW swell, so it's got the potential to go off. The water's about average for this time of year, so no surprises there.
The first real opportunity is Thursday morning, July 30th. Turtles is showing a clean 4.6ft SW groundswell with a very long 16-second period. The wind is glassy, coming in from the SSE at just 3 mph. This is going to be a special session. The combined swell energy is substantial at 1057, and the whole setup is screaming "excellent" for those who can handle it. This is the standout.
Things get messy Thursday afternoon when the wind swings around to a cross-onshore, so no good there. Friday morning, July 31st, is a bit of a letdown. The swell drops to 4.3ft, and the wind is a moderate cross-offshore breeze at 12 mph. The energy is high at 1235, but it's only a marginal call. The afternoon is a write-off.
Saturday, August 1st, pushes a bigger 6.9ft swell, but the wind is a moderate cross-offshore all morning. The energy is cranking at 2102, but the conditions are rated as marginal. It's a clean-ish wave, but not the cleanest we'll see.
Sunday, August 2nd, is a similar story. A 5.9ft to 6.2ft SW swell with a moderate to long period, but the wind is never quite right. The morning is a clean cross-off, but the afternoon gets a light cross-on. Both are marginal.
Monday, August 3rd, and Tuesday, August 4th, are where things get interesting again. Monday morning has a 4.9ft SW swell with a 19 mph cross-offshore wind, keeping it clean but marginal. Then Tuesday morning, August 4th, we get a 4.6ft, 16-second SW groundswell with a light cross-offshore breeze. The energy is strong at 1467. It's classed as excellent. But the real gem is Tuesday afternoon. A 6.2ft WSW groundswell with a very long 19-second period combines with an offshore wind from the east at 9 mph. The energy is massive at 2588, and the conditions are described as excellent. This is the second major standout window. The long period means it's going to be powerful and will likely be breaking a bit straight at the beach, but at a reef like Turtles, it should be a dream.
Wednesday, August 5th, morning keeps the good run going. A 7.2ft WSW swell with a 16-second period is clean with a light cross-offshore breeze. Energy is very high at 2663. It's another excellent call. But the afternoon goes bad as the wind turns cross-on.
From Thursday, August 6th, through to the end of the first week, it's a downhill slide. The swell stays big, peaking at 9.8ft, but the wind is onshore, cross-shore, or just plain messy. The energy is sometimes in the 2000-3000 range, but it's not worth paddling out in those winds. The morning of Friday, August 7th, is a cross-shore wind with a 7.5ft swell, which is a no-go.
The second week looks more promising for size but questionable for quality. The morning of Sunday, August 9th, shows an 8.2ft SW swell with a clean cross-offshore wind, but it's still classed as marginal. The energy is huge at 2972. Then on Monday, August 10th, the wind turns messy again.
The period from Tuesday, August 11th, to Tuesday, August 12th, is a total mess with strong onshore winds and huge, lumpy swell. Not for paddling.
Then, on Thursday, August 13th, we get a massive peak. The morning brings an 11.5ft WSW groundswell with a very long 19-second period. The wind is a clean cross-offshore from the SE at 16 mph. The energy is absolutely enormous at 8656. This is a very promising, long-range standout. It's for experts only. The power will be mind-blowing, but the long period means it could be a bit walled up at the break. Friday morning, August 14th, is still good with a 7.9ft WSW swell and clean conditions, but the energy drops to 3418.
Overall, the best bets are Thursday morning, July 30th, and Tuesday afternoon, August 4th, with Thursday, August 13th, being a huge, but uncertain, long-range prospect.

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.
