Table - best surf conditions forecast for Turtle Cove over the next 16 days.
Alright folks, Rusty here. Let’s be straight with you – it’s a grim start. We’re looking at a solid two-week stretch of close-to-nothing surf before a potential late reward.
The first real surf recommendation doesn’t show up until Monday, July 27th, meaning we’ve got a gap of well over a week with no decent options. The north-east Pacific is in a deep slumber for us. For the first 15 days, the swell is tiny (mostly under 3 ft) and the wind is messy, cross-shore, or onshore. It’s not just small; it’s poor quality. The wave energy is weak, with readings barely cracking 100 (mostly in the 12 to 97 range), so there’s no power behind any of it. This is a classic blank run for this area – it tends not to stay this way for long, but for now, it’s a write-off.
The only glimmer on the horizon is Monday morning, July 27th, at Turtle Cove. We finally get a pulse of S swell at 5 ft, with a period of 8 seconds. That’s not a long-period groundswell, but it’s the biggest push we’ve seen. The combined energy jumps to a moderate 341, which is a real sign of life. But the real story here is the wind: glassy. That’s right, glassy. The forecast shows a light ESE breeze at just 3 mph, which is practically nothing. The wave comment is “expect good surf conditions,” and for a spot that’s been dead for weeks, this is the standout. It’s a reef and point break, so that moderate S swell should wrap in nicely. The water temp is about average for the time of year. Keep in mind, this is a long-range call, so it’s promising but not set in stone. If you’ve been patient, this is the window to paddle out.
For the rest of the period, there’s nothing else worth chasing. The swell is too small, the wind is wrong, or the conditions are chopped out. Stay tuned, and I’ll keep you posted if anything changes.

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.
