The Lowdown

Alright folks, Rusty here with a look at what’s heading our way. I’ll level with ya – this isn't the most pumping forecast I’ve ever seen. We've got a long stretch of small, pretty average conditions ahead, but there is one day that has my spidey senses tingling if you're willing to wait for it.

First up, for Turtle Cove, we're staring down the barrel of a flat spell. Kicking off Friday the 4th through the whole first week, it’s a real struggle. We're talking dribbly 1 to 2ft swells from the SE and ESE, with periods barely pushing past 10 seconds, and the combined energy is weak, sitting between 26 and 82 (total weak sauce energy). The wind is all over the shop, from cross-off to cross-shore, and even on Sunday the 6th afternoon when the conditions are 'clean', the waves are only 'surfable but ordinary'. It's just not worth paddling out for that. This quiet spell drags on for a good eight days straight.

Alright, hold on. The tide starts to turn Thursday the 10th. Thursday morning brings a surprise spike: a 7ft SW swell, with a combined energy of 556 (moderate to strong) hitting the beach. Now, the period is a snappy 8 seconds, so it'll be a bit lumpy, and 7ft is getting into expert territory. The wind is strong offshore from the W at 25 mph, which will keep the faces clean, but that strong breeze is gonna make paddling out a proper workout. It's flagged as marginal, but for the brave, there will be some punchy walls if you can get into 'em. Thursday afternoon drops – 5ft SSW swell with 241 energy and a fresh cross-off wind.

After that short-lived pulse, it’s back to the small stuff. Friday the 11th sees tiny 1ft leftovers and strong cross-off winds, then Saturday the 12th is barely a ripple with a 0.3ft SE swell. The tail end of the window on Monday the 14th morning shows a glassy 1ft SE swell – glassy is a major positive for clean water, but with no height, it's just a flat lake.

Later on, Tuesday the 15th afternoon shows a 4ft SSE swell with 214 energy and clean cross-off wind, and Wednesday the 16th morning has a glassy 3ft SE swell (102 energy) – that’s surfable but nothing to write home about. There’s also a small bump on Friday the 18th with a very long 12-second period from the ESE, but with a strong onshore wind, it's gonna be a mess.

So, the only standout in this entire 16-day window is Thursday the 10th morning at Turtle Cove. It's the only time the swell gets over five feet, and the offshore wind is a blessing. If you're an experienced surfer and you don't mind the wind, that's your window. The rest is 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.
