The Lowdown
Alright, grab your board and wax—let's look at what's coming up. We’ve got Turtle Cove on the radar. That’s a reef and point setup. The next couple of weeks are a bit of a mixed bag, but there’s a standout session that’s worth planning for.
Right now, the water temp is about average for this time of year, nothing wild. The first surf worth paddling out for lands on Wednesday July 15. We’re looking at a clean, moderate offshore wind from the west, with a 4 ft swell out of the southwest. The period is a short 6 seconds, so don’t expect bombs, but the energy is moderate (121). Conditions are decent, but not a classic.
Thursday July 16 drops off a little—swell shrinks to 2 ft, and the wind goes cross-offshore. Not terrible, but nothing to get excited about. Friday July 17 is glassy in the morning, but the swell is tiny at 2 ft. Saturday and Sunday are flat and messy.
Now, the real highlight. On Tuesday July 21, the swell pumps up to 6 ft–6 ft from the SSW, with a 7 to 8 second period. The energy jumps to strong (311–429), and we’ve got a clean moderate offshore wind. That’s your window. The waves will have some punch, and with the west-southwest wind groomed into the reef, it’s going to be good. Crowds are possible here, so get there early.
Wednesday July 22 sees a return of onshore winds and chop, making it ordinary. The rest of the week into early August is mostly poor, with onshore winds, small swells, and cross-onshore chop. The wind is often onshore or straight on, so it’s a grind.
But hold on—Monday July 27 morning goes glassy, with a 4 ft south swell. It’s not big, but it’s clean. Then Tuesday July 28 morning is the real standout of the second week. The swell hits 6 ft from the south, period 8 seconds, and the combined energy is very strong (536). The wind is a light breeze, cross-offshore, so the face will be clean. The water is about average for the time of year. This is the best session on offer, but it’s two weeks out, so keep an eye on the forecast.
Wednesday July 30 morning also looks good—6 ft south swell, light offshore wind, energy at 460. Clean and consistent.
Overall, if you’re looking for a day to lock in, Tuesday July 21 is the call. Tuesday July 28 is the long-range promise. The rest is mostly small or messy.

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.
