The Lowdown
Alright, let's get into it.
First up, the next week and a half or so is all about The Cove. We’ve got a solid run of clean, offshore conditions coming our way, and while the swell isn't going to be massive, there’s plenty of fun, rideable waves on the cards. The water temp is sittin’ at 80°, which is a touch warmer than usual for this time of year – not crazy, but you’ll notice it.
We kick things off on Tuesday the 11th with some glassy conditions and a small but clean 3ft SSW swell. It’s a bit inconsistent, but the conditions are clean enough to get some fun ones. The energy is weak, (354), but it’s a start.
Wednesday the 12th is where things start to pick up. The swell jumps to a cool 3ft from the S, and the period stretches out to 18 seconds. That’s proper groundswell, and with light offshore winds, The Cove is going to be looking damn good. The energy reading is a solid moderate (879). This is the best of the first few days, no doubt.
Thursday the 13th keeps the quality high with more 3ft S swell and consistent offshore breezes. The period backs off a touch to 15-16 seconds, but it's still well-shaped and clean. Energy readings stay in that strong moderate range (717-678). This is another standout morning, especially.
Friday the 14th, we’ve still got a fun 3ft S swell, but the afternoon breeze picks up. Still offshore, so it’ll be clean, but a bit more energy in the wind. It’s a good, not great, day. Energy drops a bit to the 422-445 range.
Now, Saturday the 15th is where you might want to sit it out. The swell is still around 3ft, but the wind is howling from the NE at 22-25 mph. It’s offshore, which is good for the face, but it’s going to be a battle to get out and harder to catch waves. It's just not worth the paddling. The energy is weak to moderate (293-327).
Sunday the 16th, the wind swings onshore, and things get messy. The swell is small and chopped up. Not worth your time.
Monday the 17th, the wind switches back offshore and things clean up again. We’re back to that 3ft S swell with light winds and clean conditions. A good day to get back in the water. Energy is moderate (392).
After that, from Tuesday the 18th through Friday the 21st, the swell drops off. We’re talking small 1-2ft leftovers. It’s surfable, but nothing to get excited about. The energy is weak (146-240). You might get a fun one on a dawn patrol, but that’s about it.
Then, here’s the promising part. Saturday the 22nd, we start to see a new pulse of longer-period S swell filling in. It’s small again at 2-2ft, but the period is up at 19 seconds, which is a good sign. Energy is building back into the moderate range (382-470).
Sunday the 23rd, it’s looking glassy with a 3ft SSW swell and clean conditions. A nice pick-me-up.
But the real standout of this whole forecast is Monday the 24th of August. The swell pushes up to 3-4ft from the S, with a 15 second period. The winds are forecast to be glassy all day. This is as clean as it gets. The energy readings are the highest we see all period, hitting (754-973). This is the day to clear your schedule. It’s not huge, but the quality is going to be off the charts.
The days after that, Tuesday the 25th and Wednesday the 26th, keep things interesting. We’ve got 3-4ft S/SSW swell with clean, offshore winds for the most part. Energy remains strong (733-828). The 26th in particular looks like a great paddle-out.
So, bottom line: The best windows are Wednesday the 12th, Monday the 24th, and to a slightly lesser degree, the 25th and 26th. Keep an eye on that one on Monday. It’s a bit far out, but the signs are all pointing to a good one.
Rusty out.

Information about the The Cove Surf forecast
The above surf forecast table for The Cove provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at The Cove can be found by selecting the local surf guide option on the grey menu. Our The 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 (The 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 The 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.
