Table - best surf conditions forecast for Turtles over the next 16 days.
Alright, let’s talk Turtles. Only one break in the mix, a reef for the advanced crew, fairly consistent, exposed to the swell, and likes it from the SSW. Water temp is about normal for this time of year.
This Sunday morning, 12 July, you’ve got a clean 5ft swell from the SW with a 14-second period and a light offshore breeze from the ESE. The combined energy is 1030 (moderate). It’s a bit big for beginners, but for experienced surfers, it’s excellent. Afternoon goes cross-shore and quality drops.
Monday morning, 13 July, is where it gets tasty. 7ft from the WSW, 18-second period, light offshore wind. Energy jumps to 2568 (strong). Clean and powerful. Afternoon turns choppy.
Tuesday morning, 14 July, holds clean with a 6ft SW, 16-second period, light cross-offshore breeze, energy at 1816 (strong). Another good morning session.
Wednesday morning, 15 July, is 6ft, 14-second period, offshore wind, energy 1168 (moderate). Clean.
Thursday morning, 16 July, is marginal but clean with 5ft SW. Energy 1098 (moderate).
The big standout is Saturday morning, 18 July, and Sunday morning, 19 July. Saturday morning: 8ft from the WSW, 19-second period—very long period groundswell—clean cross-offshore breeze. Energy is 4156 (very strong). Sunday morning: 10ft from the SW, 16-second period, clean cross-offshore, energy 3832 (very strong). This is big, powerful, long-period reef stuff. Experts only. Crowds are often, so expect company.
After that, it gets messy. Monday 20 July morning is clean with 6ft, but afternoon gets wrecked by a strong cross-onshore wind. Tuesday 21 July through Wednesday 22 July is all onshore wind and rain—poor. Swell drops to 4ft to 4ft.
Thursday 23 July shows 8ft from the WSW, but with strong cross-onshore wind, it’s choppy and poor. That setup looks more interesting for kite surfing than paddle surfing.
Friday 24 July morning has a clean 8ft SW, 16-second period, cross-offshore breeze, energy 3252 (strong). Promising for experienced surfers, but it’s a week and a half out.
The weekend of 26 July offers a small clean window on Sunday morning: 4ft, offshore wind, but then back to rain and cross-shore.
Best windows: mornings of 13 July, 18 July, and 19 July. If you’re advanced and can handle solid reef, those are the ones.

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.
