The Lowdown
Alright, this is Rusty lookin' at the charts for Turtle Cove. Let's be real, it's been a tough stretch lately, and the first few days are a write-off. We're talking a solid block of nothing from Sunday, the 26th of July, all the way through to Thursday, the 31st. The wind has been howling onshore or cross-shore, and the waves have been a mess of chop. The energy's been all over the place, from a weak 46 (moderate energy) to a proper beating of 532 (strong to very strong wave energy) on the 29th, but all that power just meant blown-out, heavy rain surf. Not worth paddling out for.
The tide turns on Friday, the 31st of July. We get a clean little pulse with a light offshore breeze from the WNW. The swell is a modest 3 ft straight out of the south with a period of 9 seconds. That's a bit of groundswell energy making it in, and the combined energy sits at 152 (moderate wave energy). It's surfable, but the conditions are just "very ordinary" – not a standout, but a sign of life.
Now, here's the moment you've been waiting for. Saturday, August 1st. The morning is a absolute beauty. The forecast shows glassy conditions with a light westerly wind, swinging offshore. The swell is a clean 3 ft from the south with an 8-second period, and the combined energy is a solid 121 (moderate wave energy). This is the best on offer. The water temperature is about average for the time of year, so no surprises there. It's a small window of perfection.
After that, it's a game of patience. Sunday the 2nd and Monday the 3rd offer clean, surfable waves with light offshore or cross-off winds, but the swell is tiny, hovering around 2 ft to 3 ft. The energy is still low. It's a good time for a longboard or a log, but you won't be getting barreled. The crowds at Turtle Cove (reef and point) are reported as "sometimes" busy, so it might be a good idea to get out early.
The middle of the week sees a bit more size. Wednesday the 5th of August morning has a 5 ft south-southwest swell with a clean cross-off wind. The combined energy hits 234 (moderate wave energy), but the report flags it as "marginal surf forecast." It's a bit of a wildcard. By Thursday the 6th, the swell is up to 6 ft, but the energy is a strong 401 (strong wave energy), and the wind is howling from the south-southwest at 16 mph. That's a lot of power, making it a session strictly for the experienced crew. Anything over 8 ft is for experts, and this is close.
The final few days, from the 8th to the 10th, fizzle out. Saturday the 8th morning offers a last little clean 2 ft SSW swell with a light offshore wind, but it's tiny. Then it's back to onshore junk for the rest of the run. The 16-day window is a story of one killer morning, a few clean but small days, and a lot of wind. Keep your eyes on the charts for that Saturday morning glass-off.
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.
