The Lowdown
Alright, Rusty here, let's talk about what's on the table for The Cove.
Right off the bat, we’re looking at a pretty quiet spell. The swell is tiny – we're talking ankle to knee high stuff – for the first few days. It’s not until Monday the 14th that things start to get a little more interesting, and even then, it's not going to be setting the world on fire.
The standout period is from Monday the 14th right through to Monday the 21st of September. That’s the window where the energy picks up. The swell climbs from a small 2ft to a more respectable 3ft, and it’s coming from the southwest. The period on that swell is long, around 16 to 18 seconds, so it’s a proper groundswell with some grunt to it. The wave energy is moderate to strong, hitting around 473 on the 16th and peaking at 609 on the 18th.
The best of the best? I’d be looking at Wednesday the 16th through Friday the 18th. The swell is at its strongest, around 3ft to 3ft from the SSW, and the winds are glassy or light offshore. The Cove is an advanced reef break, and it can get crowded sometimes, but with conditions like that – clean, glassy faces and a long period swell wrapping in – it’s going to be magic. That 16 to 17 second period is going to push through with real power, making those waves shape up beautifully over the reef. Water temp is about average for this time of year, so nothing crazy there.
After that, from the 22nd onwards, the swell starts to drop off and the winds turn onshore, making things messy and pretty poor. A few days there are no good options, and the end of the forecast window, from the 24th to the 26th, looks like a complete write-off with poor conditions.
So, to sum it up: it’s quiet for a few days, then we get a solid run of clean, shoulder-high groundswell at The Cove from the 16th to the 18th. That's the time to be in the water.

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.
