The Lowdown
Alright, let’s break it down. The only break in the mix is Turtles, a heavy reef that’s for advanced surfers only. It’s a ride with some top-notch moments and some real scrappy spells.
It all starts on Thursday morning, July 30. Turtles is a classic dawn mission. Water temp is about 73°, normal for the season. The surf is a clean 5ft of SW groundswell with a 16-second period. Combined energy is moderate (1057). The wind is glassy. This is the standout of the first week. Get on it before the wind switches.
Thursday afternoon: wind goes SW at 12 mph cross-on, messing up the same size surf. Choppy and not worth it.
Friday morning, July 31: swell drops to 4ft from the SW, period still 14 seconds. Wind is cross-off from the SSE at 12 mph, keeping it clean. It’s a decent session but not the top pick.
Friday afternoon: ugly. 5ft swell, strong cross-on wind.
Saturday, August 1: bigger. 7ft from the WSW in the AM, 16-second period. Combined energy is moderate to strong (2102). Wind is SE at 19 mph, cross-off, so clean. 7ft at Turtles is expert-only.
Sunday morning, August 2: another highlight. Swell is 6ft from the SW, 15-second period, moderate energy (1358). Wind is light NE at 9 mph, cross-off, turning it glassy. A top-quality session for advanced surfers.
Next week starts slow. Monday and Tuesday mornings, August 3 and 4, have clean 4ft to 5ft surf – nothing special.
Wednesday, August 5: a big day. 7ft from the WSW, 16-second period, strong energy (2564). Light SE wind at 6 mph, cross-off. Pristine, but heavy.
From Thursday, August 6, through Sunday, August 9, the wind is mostly onshore or cross, and it’s lumpy. Saturday morning, August 8, has a massive 10ft SW swell with a 25 mph SSE cross-off wind. Clean but huge.
A good one: Monday morning, August 10. Swell is 5ft from the SW, 13-second period, moderate energy (1513). Offshore wind from the east at 12 mph, clean. Quality weekday session.
Another good one Tuesday morning, August 11: 5ft SW swell, offshore east wind.
The absolute standout of the whole 16-day run is Thursday morning, August 13. Swell pumps to a massive 13ft from the WSW with a 17-second period. Combined energy is an insane 8715 – very, very strong. Wind is light N at 6 mph, cross-off. Perfect, giant, expert-only surf.
Friday morning, August 14: still big at 8ft from the WSW, 13-second period, strong energy (3218). Light NNW wind at 3 mph, slight cross-shore ripple. Still good but a heavy paddle.
The two best calls: Thursday morning, July 30, for clean, glassy conditions, and Thursday morning, August 13, for a massive, clean, expert-level swell.

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.
