The Lowdown

Alright, Rusty here again. Let's talk about Turtle Cove in feet and degrees.

This stretch doesn't look super inspiring overall. The data shows a lot of small, weak energy for most of the 16-day window. There's a bit of a spike in size at the very end of August and start of September, but the winds are messy and it's still not coming together for a proper session. We're looking at a long, drawn-out period of pretty ordinary surf.

Let's break it down. Wednesday the 19th of August through Monday the 31st of August is mostly a write-off. We're talking tiny swell, mostly around 1ft to 3ft. The energy is pathetic, often reading in the 20s and 30s (combined energy of all swells directed here is weak). Winds are a mixed bag, with a few light offshore moments on the 19th morning and the 30th morning, but the waves are just too small to do anything with. The water temp at the start is a balmy 71°F and the anomaly is +0.4°, so pretty much average for this time of year.

The first bit of hope comes on Thursday the 27th of August. The swell picks up to a more solid 4ft early and then 5ft in the afternoon, with a moderate 219 and 377 combined energy (moderate). It’s coming from the S, which is a bit off the optimum SE direction for Turtle Cove, but it's a real spike. The wind on Thursday morning is a cross-off from the SSW, so it’s clean. However, the afternoon turns into a stormy mess with a cross-shore wind hitting 28 mph which will be hopeless.

Friday the 28th of August looks like the best bet overall. The swell holds at 5ft in the morning and 5ft in the afternoon from the S and SSW. Combined energy is strong at 358 and 296. The wind is a clean cross-off from the SW all day, so the surface should be nice. That's the standout – a solid 5ft to 5ft SSW swell with clean 19 mph cross-off winds. It's a bit on the bigger side, so more for the experienced crew.

From the 29th, it drops back down. Saturday the 29th has clean 19 mph offshore wind from the W, but the swell is back to a tiny 2ft to 2ft. The 30th and 31st have similar small, clean conditions, but nothing to write home about. The first week of September shows a northerly wind shift and some onshore flows, killing any chance of quality from that last bump in energy.

So, the best on offer is Friday the 28th of August with a 5ft SSW swell and clean, offshore winds. It's not perfect, but it's the only window that gets the blood pumping.

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.
