The Lowdown
Alright folks, Rusty here. Let’s get into it.
We’re looking at a pretty bleak stretch for Turtle Cove, a reef and point setup. Honestly, the first solid surfable day isn’t until Wednesday the 22nd of July, and even then it’s marginal. Up until then, we’ve got a few days of almost nothing. Monday the 20th has a tiny 3ft SSW swell with weak energy (81), and while the morning is glassy, the conditions are just ordinary. The wind turns onshore pretty quick, and the whole thing is a no-go. Tuesday the 21st is a write-off with strong cross-onshore winds and a messy, choppy sea.
The first real chance to paddle out comes on Wednesday morning, the 22nd of July. We’ve got a 8ft SSW swell with moderate energy (721) and clean conditions thanks to a cross-offshore wind. It’s a bit of a beast, though – over 8ft, so this one is for experts only. The afternoon gets even bigger, pushing 10ft (1193 energy), still clean but powerful. This is a solid, heavy groundswell (8-second period), so it’ll have some grunt, but the reef bottom here should handle it well. Thursday the 23rd morning hangs on with a 7ft S swell (719 energy) and clean conditions off a NNW breeze. That’s still a solid, expert-level wave.
For a standout, I’d say Wednesday the 22nd of July afternoon is the pick. The swell is pumping (10ft, 1193 energy), the wind is clean, and it’s a bigger, more powerful day. Just know it’s not for the faint of heart. The water temperature is 67°F, which is a whopping 4°F colder than normal – that’s a noticeable chill for this time of year, so bring a thicker wetsuit.
After that, the window slams shut. From Friday the 24th of July all the way through to Tuesday the 4th of August, it’s one poor forecast after another. Onshore winds, chop, tiny swell, and weak energy. There’s a slight bump on Tuesday the 28th of July with a 5ft SSW swell, but the onshore wind ruins it. The second week of the forecast is a total desert. The only thing to note is that the swell energy drops to pitiful levels (24 to 98), and the wind is almost always onshore or cross-onshore. It’s a long, frustrating gap.
So, to sum it up: if you’re an expert, Wednesday the 22nd of July afternoon is your one shot at a proper session. For everyone else, it’s a waiting game. The break is fairly consistent, but this run is a bad one. Forecasts can change, though.
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.
