Table - best surf conditions forecast for Turtle Cove over the next 16 days.
The Lowdown
Alright, Rusty here. Let's break down the surf.
We're starting off slow. The first few days at Turtle Cove are looking pretty flat and sloppy. Water temp is 19°C, which is a bit cooler than usual, so keep that in mind.
From Sunday the 19th through Tuesday the 22nd, the swell is tiny and weak. The energy is low, the periods are short, and the wind is mostly onshore or cross-shore. It's a pretty grim stretch of ordinary, mushy waves.
Then comes Wednesday, July 22nd. The morning shows a pulse of energy building, but the real magic is the afternoon. The swell jumps to 2.4m from the SSW with a 9-second period, and the wind goes clean offshore out of the WSW. The combined energy reading is 1666, which is a serious amount of push. This is excellent surf, but at that size, it's for the experienced crew only. That's the clear standout.
Thursday the 23rd still has a decent 1.5m S swell in the morning, but the wind is a light cross-on, so the quality drops off. It gets smaller and messier from there.
From Friday the 24th all the way to Monday the 3rd of August, the outlook is grim. We're talking small, weak swell with short periods, and the wind is almost always a problem. There is a little bump in size on the 31st of July, with a 1.9m ENE swell, but the wind is cross-off or cross-shore, and the quality is just not there. It's a long, flat spell after that Wednesday.
The one and only call is: Wednesday afternoon, July 22nd, at Turtle Cove. Don't miss it.
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.
