Table - best surf conditions forecast for Turtles over the next 16 days.
Alright, let’s talk shop in feet and miles per hour.
Same story – only Turtles is the spot. A reef break, exposed to the south-west, and it’s for the advanced crew only.
Saturday the 11th of July starts off okay. Saturday morning, some clouds, but a clean 4ft swell from the SW with a solid 13-second period – that’s a groundswell. The wind is light and cross-offshore from the ESE at 6 mph, so the lineup looks tidy. The combined energy is moderate at 382. Saturday afternoon, the wind swings SW at 12 mph, turning cross-on and choppy – forget it.
Sunday the 12th is better. Morning is clear, with a light 9 mph offshore breeze from the ESE. The swell holds at 5ft with a 14-second period, and the combined energy jumps to 946 – solid. Great morning. Afternoon gets messy again with cross-shore wind and a 4ft WSW swell with a long 17-second period – too much period for comfort and messy wind.
Monday the 13th is the standout. Morning is clean – 6 mph cross-offshore from the ESE, and the swell pumps to 7ft from the SW with an 18-second period. That’s a proper long-period groundswell, and the combined energy is 2706 – strong. This is for experts only; over 8ft is expert territory, and at 7ft it’s pushing it for anyone not experienced. Long waits between sets, but the quality will be worth it. Tuesday the 14th is similar but a touch smaller at 6ft, with a clean offshore from the ENE at 6 mph and a 16-second period. Energy at 1816. Another morning winner.
Wednesday the 15th keeps it going – 6ft from the WSW, 14-second period, clean light offshore from the east at 6 mph. Energy at 1168. Good clean waves for the experienced. Thursday the 16th drops to 4ft, but still a long 16-second period and a cross-offshore NNE breeze at 9 mph keeps it clean.
From Friday the 17th, things get rough. The wind turns onshore or cross-on, and while the swell sticks around 5ft to 8ft, the quality suffers. Saturday the 18th has a 7ft WSW swell with 15-second period and a strong 15 mph cross-shore wind – combined energy 2202, but it’s messy. Sunday the 19th is similar with 8ft and moderate cross-shore winds. Monday the 20th drops to 7ft, but a fresh 18 mph cross-offshore from the SSE keeps the surface clean – still, energy fading.
From Tuesday the 21st through to Sunday the 26th, the swell is 3ft to 5ft with fresh to strong winds (15 to 25 mph) from the south or southeast. Combined energy mostly below 1000, and conditions are either clean but weak or choppy and messy. Thursday the 23rd and Friday the 24th are particularly poor with strong winds and lumpy chop.
The standout sessions are the mornings of Sunday 12th, Monday 13th, Tuesday 14th, and Wednesday 15th July. Monday 13th July morning is the big one – 7ft SW groundswell with an 18-second period, light offshore wind, and strong energy (2706). That’s the best on offer for the advanced surfer. Sunday 12th is also a cracker with clean 5ft and lighter winds.
If you’re a beginner, stay away from anything over 5ft – that rules out most of the best days. The second week (from 21st July) is a struggle – small swell and strong winds. Not much to get excited about.

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.
