The Lowdown
G’day, it’s Rusty here. Let’s be straight with you: the next couple of weeks are looking flat and pretty damn frustrating for surfers. We’ve got a long stretch of nothing on the cards, and it’s going to be a real test of patience.
The only wave we’re looking at is at Coastguard Beach, but even that’s a marginal call. The outlook starts on Friday the 28th of August with basically nothing. Swell is a dribbly 1ft from the ESE with a short 8 second period. It’s a cross-shore breeze making it choppy. The water is a touch warmer than normal for this time of year at 70°F, which is the only thing that’s got a bit of life in it.
The whole first week is a write-off. We’re talking days and days of tiny, weak surf. Sizes stay under 3ft, periods are short, and the winds are all over the shop. It’s a real flat spell.
The one bright spot, and I mean the only one, looks like it’s going to be around Sunday the 6th of September. That’s over a week away, so it’s promising but I wouldn’t book the day off work just yet. The models are showing a pulse of NE swell pushing the waves up to 5-5ft. The period jumps to 11 seconds, so it’ll have a bit more push to it. The energy reading is strong too, with the combined energy hitting 959 on Sunday morning and 632 in the arvo. Still, the wind is going to be blowing cross-shore from the north, which will put a bit of a chop on the face. It’s not going to be glassy, but it’s the best we’ll see.
Before that, on Saturday the 5th, there’s a slight bump of NE swell to 5-6ft, but the period is only 8 seconds and the north wind is howling at 22 mph. That’s going to be a lumpy, ropy mess. In fact, with that size and strong cross-shore wind on an exposed beach, the setup looks more interesting for kite surfing than paddle surfing.
After that little pulse, it fades right back out again. The second week just dies off to nothing, with waves around 0.7-1ft. So, there you have it. A long, flat run with one average-to-okay day about a week out. It’s a tough stretch, but this area can turn around quickly, so keep an eye on the charts. I’d be checking back closer to the 6th to see if that swell firms up and the wind backs off.
Rusty.

A general guide to surfing at Coastguard Beach can be found by selecting the local surf guide option on the grey menu. Our Coastguard Beach 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.

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 Coastguard Beach 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.
