The Lowdown

Alright, Rusty here. Let's have a look at what's cookin' over at Turtle Cove. I gotta be straight with you, this outlook is a bit of a heartbreaker for the most part. The water temp is sitting at 69°F, which is about average for this time of year, so at least you won't be freezing your bollocks off while you're looking at flat waves.

The first week and a half is a total write-off for surf. From Saturday the 12th right through to the morning of Tuesday the 22nd, it's pretty much all "poor surf conditions." We’re talking tiny swell, with heights mostly below 3ft, and the wind is just all over the shop – cross-shore, onshore, gusty. It's a tough stretch, and the wave energy is pathetic, hanging around in the low double digits (like 23 or 70). There is a brief moment on the 13th and 14th where the wind is clean and cross-off, but the swell is just too weak to get excited about. It's basically a long flat spell with a bit of cleanup on a few mornings.

Now, we finally get a pulse of energy moving into the second week, towards the end of the month. The first real standout appears on Wednesday the 23rd of September. By the afternoon, we see a jump in the swell height to 7ft from the SE, and the combined energy goes up to 352 – that's proper moderate energy. The wind swings around to a cross-off from the NNW, cleaning things up nicely. This looks solid for the more experienced crew; those waves are getting a bit too beefy for beginners. The swell period is only 6 seconds though, so it's wind swell, not that long-lasting groundswell, but it'll be fun if you can get on it.

Following that, on Thursday the 24th, the swell drops back to 5ft from the SE with 8 second periods, still showing some energy (280). The wind turns onshore from the East though, so it's not as clean as the day before. If you're an expert, the 23rd afternoon is your window.

Then, we get a strange shift. On Friday the 25th, the swell drops to 2ft from the E, but the wind goes proper offshore from the WSW at 19 mph in the morning. The wave energy is still moderate (136). This is a glassy, clean option for a longboard or a fish – it won't be big, but it'll be the cleanest, most lined-up wave of the whole two weeks.

So, to sum it up: if you're an expert, circle Wednesday the 23rd of September. For everyone else looking for a clean, smaller wave, Friday the 25th of September is your best bet for some silky smooth conditions. It's a long wait.

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.
