Alright, this is Rusty.
I gotta be straight with you – Turtle Cove is looking pretty flat and bleak for the next week and a half. There’s a long dry spell from now until around the 22nd of July. Most of the time the energy is weak, and the wind is messing things up.
Let’s take it day by day.
For the first part of July, from the 8th through the 18th, it’s mostly a write-off. We’ve got small, weak, short-period swell – mostly under 3 feet and with periods barely scraping 8 seconds. The wind is almost always cross or cross-off, and when it is offshore, the swell is just too pathetic to bother. The water temp is sitting around 67°, which is pretty normal for this time of year, no big anomaly there. Wednesday morning the 8th sees a tiny 4 foot NE windswell, but it’s cross-on and weak – just not worth the paddle.
The first real glimmer of hope doesn’t show up until Sunday the 19th of July. The morning session has a pulse of 4 foot S swell, and more importantly, we get a moderate offshore wind from the W-SW. That should clean things up nicely. It’s still only decent, not a standout, but it’s the best we’ve seen for a long time. The afternoon on the 19th is blown out again with a fresh cross-off breeze.
Then we hit a dead period again on the 20th and 21st – tiny, weak stuff. Tuesday the 21st barely registers with a 0.3 foot long-period swell (12 seconds) that has almost no energy. That’s just a ripple.
Now, here’s the one you want to circle on your calendar. Wednesday the 22nd of July, morning session. Turtle Cove gets a shot of 5 foot S swell with a period of 7 seconds, and the energy is strong. But the real winner here is the wind: glassy, dead calm. That means the ocean will be like a mirror. For a reef and point break like Turtle Cove, that is a beautiful thing. The waves should be clean and fun. It’s a solid intermediate-sized swell, not too big for most of you, but over 5 feet so maybe a step up for beginners. The afternoon on the 22nd gets chopped up by a cross-shore wind, so hit it early.
Thursday the 23rd is a step down, with a 4 foot S swell but a cross-on breeze from the NE – not great.
So, the true standout is the morning of the 22nd of July. Mark it. A long wait, but it could be worth it for some glassy, clean lines at the Cove.
Stay frothy.
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.
