The Lowdown
Alright, sit down. Rusty here, and I gotta level with you: the next couple of weeks at Turtle Cove are looking flat and funky. This is a reef-and-point break that needs a good SE pulse to fire, and we're just not seeing it. Water temp's 70°, right where it should be for this time of year – nothing wild.
We kick off Sunday August 30th with a tiny 1 ft SE swell, period a short 8 seconds, and a cross-off breeze blowing 12 mph. It's clean but there's zero power – combined energy only 30 – nothing to ride. Monday the 31st is more of the same: a light easterly onshore, still 1 ft at 8 seconds, still poor. Tuesday September 1st brings a bit more height (2 ft) but period drops to 7 seconds and light rain falls – still no good. Wednesday the 2nd shows a bump: 5 ft SE swell (6-second period) but with a 16 mph cross-onshore wind, making it choppy. Combined energy hits 157 – moderate – but the quality is trash. Thursday through the rest of that week stay small and ordinary, with occasional clean moments but waves only 1–2 ft.
Into the second week, it doesn't turn around. Tuesday September 8th brings 6 ft SE swell (still only 6-second period) and energy jumps to 310, but the wind is onshore and conditions are marginal at best. Wednesday the 9th has the biggest energy of the run – 460 – with 5 ft ESE swell at 8 seconds, but again it's cross-shore breeze and just not rideable. After that it fades back to tiny, clean but powerless waves through the 14th.
Honestly, there's zero sessions worth paddling out for. Crowds can pop up here sometimes, but with waves this weak you won't have to worry about company. Keep an eye on the charts – maybe something shifts – but for now, leave the boards in the garage. This is Rusty, signing off.

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.
