The Lowdown
Alright folks, Rusty here with a look at what’s coming down the pipe for Turtle Cove. It’s a pretty quiet start, so we’re gonna be patient.
The first real chance to paddle out comes Wednesday the 15th in the morning. Turtle Cove is a reef and point setup, and it's exposed to the swell. We’ve got a 4ft swell from the southwest, but the period is a short 6 seconds, so it won’t have much push behind it. The wind is offshore from the west at 16 mph, which should keep things clean, but the energy is moderate, sitting at 140. The water temp is 68°, which is a bit colder than normal for this time of year. It’s surfable, but ordinary is the word.
That afternoon, the wind shifts to a cross-off, the swell drops to 4ft, and the quality just isn't there. Thursday morning the 16th is even smaller with a 2ft swell, and Thursday afternoon the 16th is a total write-off. We’ve got a long, quiet spell here – nothing worth chasing from Thursday the 16th through to the morning of Saturday the 19th. It’s a dead run.
Now, Sunday the 19th morning brings a pulse of energy. The swell jumps to 7ft from the SSW, but the period is still short at 7 seconds. The wind is a fresh offshore from the west at 22 mph, which is clean, but the energy is moderate (385). Honestly, with that short period and size, it might be a bit of a washing machine and too much for beginners. The afternoon cleans up a bit, the swell drops to 6ft, and the period stretches to 8 seconds, with energy hitting 404. The offshore wind is still blowing, and this is when conditions actually look *good*.
Monday the 20th morning is the standout here. The swell is a solid 5ft from the south with a 9-second period, which is a proper groundswell. That longer period means better shaped waves, more energy, and longer lulls between sets. The wind is glassy – yes, glassy – swinging to a light offshore from the WSW at just 3 mph. The combined energy is strong at 326. This is the session to circle on your calendar. Turtle Cove is a reef and point, so that longer period will translate into lined-up waves, not just closeouts. It’ll be clean, punchy, and uncrowded most likely if you get out early.
After that, things get messy. Monday afternoon and through Tuesday the 22nd, the wind goes cross-shore or cross-off, and the quality drops off. Wednesday the 23rd through to Friday the 24th morning is a bust – small, onshore, and weak. Friday the 24th morning is glassy again (2ft from the SE), but the swell is tiny and the energy is weak at 52. Not worth the drive.
Looking further out, there’s a promising trend for the final week. Sunday the 26th afternoon has a 3ft south swell with a moderate offshore wind, and the energy is strong at 232. Monday the 27th morning is the second real standout. We’ve got a 4ft south swell with a 12 mph offshore breeze from the WSW, and strong energy at 241. The conditions should be excellent – clean, punchy, and consistent. It’s a long-range call, so don’t bet the house on it, but it’s got the makings of a good session.
The rest of the month into the 30th is mostly small, onshore, and poor. A few marginal moments but nothing I’d clear my schedule for.
Rusty signing out.

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.
