Table - best surf conditions forecast for Turtle Cove over the next 16 days.
Alright, let’s talk in feet and knots. Rusty here, and I’ll level with you – this is a tough 16 days. The only break we’ve got is Turtle Cove, a reef and point. It’s fairly consistent, but the conditions are mostly a bust, so don’t get your hopes up.
We start on Friday, July 10th with a small morning swell. Wave height is about 2ft, coming from the SSW, with a short period of 5 seconds. That’s weak, crumbly energy – combined energy is only 56, so it’s barely got any push. The wind is light offshore from the WNW, keeping it clean, but the waves are tiny and weak. The afternoon turns gusty with WSW winds at 15 knots, and the swell drops to 1ft. Not worth a paddle.
Saturday, July 11th and Sunday, July 12th are a total loss. The wind is cross-onshore, making it choppy, and the swell stays under 2ft. The energy is low (42 to 68), and the period is short. Nothing to do.
Monday, July 13th through Wednesday, July 15th are a dead zone. The swell is tiny – 1ft to 2ft – with weak energy (under 40). The wind is mostly offshore or cross-off, but there’s simply no wave power. You’d be floating on a pond.
Then we get a glimmer on Thursday, July 16th morning. The wind goes glassy, dead calm from the NNE, and the swell bumps up to 4ft from the SSW, with a period of 6 seconds. Combined energy jumps to 113 – that’s moderate energy. The waves are surfable, clean, but not epic. Still, with the glassy surface, it’ll be the best of the whole period. The morning is your window.
Friday, July 17th morning is similar – 3ft from the SSW with light offshore wind – but the energy is a bit lower (91). It’s clean, but again, not a standout.
Now, things get ugly from Saturday, July 18th onward. The swell starts building, but the wind turns onshore and strong. By Sunday, July 19th, we’re looking at 5ft to 7ft from the SSW, but with heavy onshore winds up to 25 knots. The combined energy is high (250 to 373), but it’s blown-out and messy. Not for paddling – this is more of a kite-surfing setup.
The second week is a blur. Monday, July 20th through Wednesday, July 22nd sees the swell climbing to 8ft, with energy readings over 800, but the wind is howling onshore or cross-onshore, making it rough and choppy. These waves are big for beginners (over 5ft) and only for experts if they’re keen, but the wind ruins it.
Thursday, July 23rd to Saturday, July 25th is a slow fade-out. The swell drops from 5ft to 2ft, with energy falling from 178 to 30. The wind stays mostly cross-off, but there’s no juice left.
The one standout? It’s the Thursday, July 16th morning session at Turtle Cove. Glassy conditions, 4ft swell from the SSW, and moderate energy. It’s not pumping, but it’s the cleanest wave you’ll see in this whole run. The water temp is about average for the time of year – nothing weird.
Honestly, this is a lean stretch. If you’re keen to get wet, aim for that Thursday morning. Otherwise, keep the board in the car and wait for the next swell.
Rusty.

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.
