Table - best surf conditions forecast for Turtle Cove over the next 16 days.
Alright, let’s break down what’s happening at Turtle Cove.
Water temp is about 68°F, which is pretty standard for the season—no surprises there. Now, the next few days are honestly a bust. From Tuesday the 7th through the end of the week, we’ve got nasty cross-onshore wind and tiny, weak swell. Energy readings are under 134 (weak), and waves are barely 3ft. Just lumpy, poor stuff. There’s a big gap with no real surf to speak of.
But Wednesday morning the 8th offers a brief glimmer. It’s glassy, with a light offshore from the WNW, and a fun 5ft swell out of the ENE. The energy jumps to 496 (moderate), period is short at 7 seconds so it’ll be a bit bumpy, but it’s clean. That’s the highlight for a while, even if the direction isn’t perfect.
After that, it’s back to small, clean but tiny waves until the second week. Friday the 10th has a 2ft south swell with light offshore wind in the morning, but it’s really nothing special.
The big standout—and the only one worth circling on the calendar—is Monday the 20th of July. That morning is firing for experienced surfers: a solid 10ft south swell with a 10-second period, light offshore WSW wind, and massive energy of 1668 (strong). It’s glassy, so you’re looking at proper clean waves at the reef and point. That’s a proper session. Sunday the 19th builds with 6ft but has shorter period and cross-off wind—decent, but Monday is the real deal.
Monday morning the 20th. That’s your wave.
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.
