Table - best surf conditions forecast for Turtles over the next 16 days.
Alright, Rusty here. Let’s break down this 16-day forecast for Turtles.
We kick off Monday July 13th with some proper groundswell. The water temp is 74°, which is pretty normal for this time of year – no surprises there.
The best of the early run is Monday morning the 13th. You’ve got a solid 7ft SW swell with a very long 18-second period, pumping out over 2700 units of energy. The wind is light and cross-off from the ESE, so it’ll be glassy and clean. This is serious reef-break territory for advanced surfers only. Crowds are often here, so expect company.
Tuesday the 14th morning is still excellent: 6ft from the SW, 16-second period, and a light NNE cross-off. Clean and powerful.
Wednesday the 15th morning drops a bit to 6ft from the WSW, 14-second period, with an ENE cross-off. Still clean, but the energy is backing off.
Thursday the 16th morning is rideable at 4ft with a 14-second period, but a north wind at 12 mph makes it a bit messy.
Friday the 17th is a mess – cross-shore winds and chop. Skip it.
Saturday the 18th morning brings a rebound: 6ft from the WSW, 14-second period, light ESE cross-off. Clean and fun.
Sunday the 19th morning is a big one – 8ft from the WSW, 15-second period, with a south-southeast cross-off at 12 mph. Energy is cranking over 3100 units. This is expert territory – powerful and big, but clean-ish.
Monday the 20th morning drops to 6ft from the SW, 13-second period, but cross-shore winds make it tricky.
Tuesday the 21st through Wednesday the 22nd is mostly blown out and dropping – not worth it.
Now, a sleeper: Thursday the 23rd morning. Only 3ft of swell, but a very long 20-second period from the WSW. Light cross-off from the SE, clean and glassy. Great for a longboard if the tide works.
The absolute gem of the whole forecast is Friday morning July 24th. Glassy – dead calm – with a solid 7ft WSW groundswell and a 16-second period. Over 2000 units of energy. This is a perfect morning for experienced surfers. Get on it.
Sunday the 26th morning has another glassy session with 4ft from the SW at 15 seconds. Clean but much smaller.
From Monday the 27th onward, it’s mostly onshore wind and chop. Not much to get excited about.
So the call is clear: Monday the 13th is strong, but the number one standout is Friday the 24th – glassy, clean, and solid. That’s the one.
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.
