The Lowdown
Alright folks, let’s break down the next 16 days at Turtle Cove.
The first few days are a real nothing show. Monday the 27th of July starts off glassy with a 2ft SE swell, but there’s barely any push to it (72 energy) and the waves are just ordinary. That afternoon the wind goes cross-off, but the swell drops even smaller. Tuesday and Wednesday morning are both poor – Wednesday morning actually has heavy rain and a messy 6ft cross-on swell that’s just a mess.
Then, Wednesday afternoon is where we see a change. A clean 6ft SE swell (556 energy) with a gentle offshore wind – that’s a fun session in the making. The period’s a bit short at 7 seconds, but that offshore breeze will clean it right up. Thursday morning keeps the clean run going with a 3ft SSE swell (314 energy) and glassy conditions – real nice for a longboard or fish.
Friday and the weekend drift back into average territory. Friday morning is a bit crossed up, and the sizes hang around 2ft to 4ft with weak energy. Saturday morning is dead flat and glassy but tiny.
Now, the big one – and I mean the big one – is Monday the 3rd of August. We get a chunky 8ft SSE swell from the south-east, with a solid 10 second period, pumping in 1282 energy. That’s a lot of power. Morning brings a light offshore wind from the WNW, so expect clean, heavy lines. This is strictly for experts – 8ft is well into the big stuff. Turtle Cove is a reef and point break, so it will handle this long-period groundswell perfectly, keeping the waves from closing out.
After that, the size drops but stays ridable. Tuesday the 4th has a clean 5ft S swell (307 energy) with glassy morning conditions – great for intermediates. Wednesday and Thursday get messier as the wind picks up and the period shortens. Into the second week, from the 7th onward, it’s mostly small, weak, and wind-battered, with only a few knee-high bumps. The 8th and 9th offer tiny 3ft to 4ft SSW swells, but the wind stays reasonably clean.
Bottom line: the first week has one real standout on the 3rd of August, and a few smaller windows around the 30th and 31st of July. The rest is mostly flat or blown out. Turtle Cove is a fairly consistent spot though, so this kind of quiet stretch is not the norm. The forecast could change.

Information about the Turtle Cove Surf forecast
The above surf forecast table for Turtle Cove provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Turtle Cove can be found by selecting the local surf guide option on the grey menu. Our Turtle Cove 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 (Turtle Cove) 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 Turtle Cove 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.
