The Lowdown

Alright folks, Rusty here. Gotta be straight with you – it's a bit of a slow start, but there's some light at the end of the tunnel if you're patient.

For the next few days, we're looking at small, weak energy. The water's sitting at a nice 80°, which is bang on average for this time of year, so no surprises there. The combined swell energy is barely cracking 200 (228), so it's pretty weak. The Cove is an inconsistent, advanced reef break, so it's not really doing much for us. Thursday through to Tuesday next week is just a run of ordinary, small waves. You'll see a few glassy windows, like Thursday afternoon and Saturday morning, with tiny 2 ft to 2 ft SSW swells, but the quality just isn't there. It's more of a paddle-around than a surf session.

Now, things start to get interesting around Wednesday, the 26th. The swell ticks up a notch, and we see a nice jump in energy. Wednesday morning looks promising with a 2 ft S swell, a period of 18 seconds (that's proper groundswell), and a light offshore wind from the north. The combined energy is moderate at 438. That's a solid improvement.

But the real standout is Thursday, the 27th. We're looking at the best wave of the fortnight. Thursday morning you've got a 3 ft SSW swell, a 16-second period, light offshore cross-off wind from the north, and the combined energy is a strong 716. That's a proper pulse of energy. The waves will be clean and have some punch. Just remember, The Cove is an advanced, inconsistent reef, so when it's on, it's on, but it won't be for everyone. The offshore wind is a major positive here.

After that, it tails off again. The end of August and start of September sees the swell drop back to small, weak 1 ft to 2 ft stuff. The energy levels drop back to weak (111-205). The winds stay offshore, which is nice, but there's just not enough swell to get excited about. Even into the first week of September, the onshore winds and small swells don't offer much. There's a brief flicker on Friday, the 4th, with a 2 ft SSW groundswell (19 seconds) and glassy conditions, which could be worth a look if you're desperate, but it's a long way off.

So, to sum it up: the first week is a write-off for quality waves. The clear best is Thursday, the 27th of August. Get on it if you can. The rest is mostly small and ordinary, with a few clean but tiny windows.

Rusty.

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.
