The Lowdown
Alright, my fellow wave hunters, Rusty here to break down the next two weeks.
Let’s be real, it’s a tough forecast. Turtle Cove is looking at a long stretch of poor conditions. The first real opportunity doesn’t pop up until Friday afternoon, the 4th of September, and it’s a small one. There’s a gap of several days of nothing before that.
The water temp is right around average for the season, so no shock there.
That Friday afternoon, the 4th, we get a bit of a break. The wind is offshore from the WNW at 12 mph, cleaning things up. The swell is a tiny 2ft from the SSW with a short period of 7 seconds. The combined energy is weak (81). It’s surfable, but it’s a marginal session. If you’ve got the itch, that’s your best bet.
After that, it’s back to the grind. Saturday the 5th and Sunday the 6th are a mess with onshore winds and choppy conditions. The entire following week, from the 7th through the 15th of September, is a constant struggle with cross-onshore winds and tiny, weak swell. The mornings of the 11th, 12th, and 13th of September offer clean conditions with light offshore winds, but the swell is only 1ft to 2ft. You’ll be paddling your arms off for a knee-high wave.
The most interesting pulse comes Monday the 7th of September, with a 3ft east swell at a 12-second period, giving us a moderate combined energy of 181. But the onshore and cross-onshore winds ruin any chance of it being clean. It’s a classic case of the swell and the wind not lining up.
This is one of those quiet windows for the area. Nothing’s really firing. Keep your eye on the charts, but for now, it’s a waiting game.
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.
