The Lowdown

Alright folks, Rusty here. Let’s have a look at the 16-day window for Turtle Cove. I’ll be straight with you – it’s not going to be a wild ride. We’ve got a long stretch of small, weak waves ahead, with a few moments that might just be worth a paddle.

The overall pattern is quiet. For the first several days, the swell is tiny and the energy is low. The best chance for anything decent comes later in the period, but nothing is a guaranteed classic.

The standout session is the Thursday morning, September 10th. We get a spike of 6ft swell from the SW, with a moderate cross-offshore breeze from the WSW. That’s clean conditions. The combined energy hits 408, which is moderate, so there’s some push. The period is short at 7 seconds, so it’s a windswell, not a groundswell, but at this size, it’ll offer some fun, punchy walls on the reef. It’s intermediate-level stuff, so keep your wits about you. The water temp is about average for this time of year.

The secondary option is the Thursday afternoon, September 10th with 5ft from the SSW and clean cross-off wind. The energy drops to 278, but it’s still surfable if you missed the morning session.

For the rest of the first week, we’re looking at knee to waist-high dribble. The Friday afternoon, September 11th has a tiny 2ft from the SSW with a gentle offshore breeze from the west, making it clean. The period is only 6 seconds, so it’s weak, but a longboard might get a glide. The Monday afternoon, September 14th is glassy with 3ft from the SSE, but again, minimal energy.

The second week is a write-off until the Sunday morning, September 20th where we get a pulse of 6ft from the east, but it’s cross-onshore and choppy, making it messy. The energy is 207, but the wind ruins it. The Monday morning, September 21st has a cleaner 4ft from the ENE with a cross-offshore breeze, but it’s still not great.

And then, a true wildcard appears on the Thursday morning, September 24th. We get a 2ft swell from the SSE, but with a very long period of 18 seconds! That’s a groundswell with serious energy (341). The wind is a moderate cross-shore from the NNE, creating a cross-chop. This long period swell at a reef and point break like Turtle Cove could produce some surprising, lined-up waves, but the chop might make it tricky. This one is promising but less certain being so far out.

So, to sum it up: the best bet is the Thursday, September 10th, for the cleanest, biggest swell. If you’re a longboarder, the glassy afternoons mid-week might be your only option. Otherwise, it’s a lot of flat and windy days.

Stay tuned, and keep the wax soft.

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.
