The Lowdown
Alright, I’m Rusty, and this is my read on the coming swell window for The Cove.
We’ve got a slow start over the next few days, but don’t write it off just yet. The Cove is a tricky little reef setup, and it’s inconsistent, so when it turns on, it’s worth the wait. The water temp is sitting pretty average for this time of year, nothing unusual.
The first real chance to get wet won’t be until Tuesday the 25th of August. Through the middle of the week and into the following weekend, we start seeing some proper groundswell rolling in from the S and SSW, with periods stretching out to 18 seconds. That’s long-period energy, and for a reef like The Cove, that’s exactly what you want – it’ll wrap in nicely and hold shape. The combined energy climbs into the moderate range (459) by Wednesday the 26th, and by Thursday the 27th we’re pushing strong energy (639). That’s the standout window.
Thursday the 27th morning is looking magic: clear skies, light offshore breeze from the north, and a 4ft S swell at 16 seconds. It’s not huge, but on a reef, that’s going to produce clean, well-shaped waves. The winds stay light and cross-off through the afternoon, so it’s all good. This is the best of the run – a proper session for the experienced surfer.
Friday the 28th keeps the good times rolling with similar conditions, though the swell eases a touch. The following days into early September bring continuing S groundswell, mostly clean thanks to offshore winds, but the size drops back under 3ft. The combined energy stays moderate, and the consistency is okay for an inconsistent spot.
If you’re a beginner, the swell stays under 5ft across the whole period, so it’s not intimidating, but The Cove is an advanced reef break, so be cautious. The real prize is that Thursday the 27th and Friday the 28th – mark it.
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.
