The Lowdown
G’day, Rusty here. The Cove is a reef for the advanced crew, and it’s inconsistent, so it keeps you guessing. The water’s about average for this time of year.
We get surf starting Thursday, August 13. Thursday morning, the swell is 4 ft from the south with a 16-second period – that’s groundswell, proper energy. The combined energy is 719 (moderate), and with a 12 mph offshore breeze from the NNE, it’s clean and lined up. This is the best of the whole run. The afternoon holds 4 ft, 15-second period, energy at 678 (moderate), still offshore. For advanced surfers, this is the one.
Friday the 14th, 3 ft from the south, 14-second period, energy around 446 (moderate). Offshore winds, still clean. Saturday morning, August 15, 3 ft, 13-second period, energy at 304 (moderate), but the wind turns cross-off in the afternoon, and it gets messy. Sunday the 16th, morning has 4 ft from the south, 16-second period, energy at 656 (moderate), but the wind is cross-off, and it’s marginal. The afternoon is a washout.
Monday the 17th, back to clean, 3 ft, 14-second period, energy at 332 (moderate), light offshore. Tuesday the 18th morning, glassy, 2 ft, 13-second period, but energy is weaker at 236 (moderate). Surfable but ordinary. Wednesday the 19th through the end of the week, swell drops to 2 ft to 2 ft, with periods up to 18 seconds, but energy is low, between 136 and 288 (moderate). Most days have offshore or glassy wind, but the waves are small.
Second week, Monday the 24th, 2 ft from the SSW, 14-second period, energy at 273 (moderate), clean. Tuesday the 25th morning, 2 ft, 16-second period, energy at 404 (moderate), clean. Wednesday the 26th, 3 ft, 14-second period, energy at 537 (moderate), offshore. The arvo has 2 ft from the south, 19-second period – very long groundswell, energy at 532 (moderate). That long period will be a dream on the reef. Thursday the 27th and Friday the 28th, 2 ft to 3 ft, mostly clean. Crowds can pop up sometimes, but with the inconsistency, you might score it quiet.
The absolute standout is Thursday, August 13, with that 4-4 ft south groundswell and non-stop offshore wind. The next best is Wednesday the 26th, especially the arvo with the 19-second period, and Thursday the 27th. Lock in those dates.
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.
