The Lowdown

G’day, Rusty here. Let’s be straight with you—this stretch of coast is looking pretty flat and grim for the next couple of weeks. We’ve got a long window of nothing on offer, so if you’re hanging for a wave, you might want to find another hobby for a while.

The first decent sign doesn’t even show up until Friday, September 18th. That morning, we finally see a bit of life with a summary swell height of 4ft from the northeast, but the period is short at 6 seconds. Combined energy is still weak at 102, and while the wind is cross-offshore, the forecast still calls it poor surf. By the afternoon, it drops to 3ft and the period stays short. There’s a light offshore breeze, making things clean, but it’s still just surfable—nothing to write home about. That’s the best we get, and honestly, it’s a pretty low bar.

Before that, you’re looking at a solid stretch of nothing. From now all the way through to the 17th, there’s no surf worth paddling out for. Swells are tiny, periods are short, and the wind is mostly cross or onshore. There are a few glassy moments—like Monday the 21st when the wind drops to almost nothing—but even then the swell is only 1ft with a 6-second period. It’s flat, plain and simple.

The only other ripple of interest is on Sunday the 20th when a 3ft south-southwest swell shows up in the afternoon, but it’s short-period and the wind is cross-onshore and choppy. Not worth the effort. Later in the month, on Tuesday the 22nd, there’s a 3ft north-northeast swell but again, it’s short-period and the wind is cross-shore. Forget it.

Water temp sits at 66°F at the start, which is about average for this time of year—nothing crazy there. But the lack of swell is the story here. There’s just no push, no energy, no reason to get wet unless you’re a kite surfer. With these small, choppy, cross-shore conditions, the setup looks far more interesting for kite surfing than paddle surfing, if you ask me.

Everything is just flat and weak. The combined energy values are mostly in the single digits and teens, barely reaching double figures. It’s a dead spell. Chin up, though—this kind of blank run doesn’t usually last forever, and forecasts can change. But for now, I’d leave the board in the garage.

Stay patient.

Rusty.

Information about the Coastguard Beach Surf forecast

The above surf forecast table for Coastguard Beach provides essential information for determining whether the surfing conditions will be good over the next 16 days. 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. If you surf the same spot (Coastguard Beach) 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 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.
