The Lowdown
G’day, Rusty here. Alright, let’s be honest—this 16-day stretch isn’t looking like a classic run for Coastguard Beach. There’s a real dry spell to kick things off and a lot of ordinary conditions to wade through before we see anything even vaguely worthwhile. The setup is a consistent beach break that’s exposed to swell, so it can fire when conditions align, but that’s just not the case here for a long while.
We’re going to have a big gap with no real surf recommendations right up until the morning of Wednesday the 16th. Before that, it’s days of poor surf—garbage onshore winds, funky cross-chop, and tiny swell that just won’t hold together. Even a Saturday the 5th sees a spike in swell energy with combined energy hitting (220) in the afternoon, but it’s ruined by a strong cross-breeze and messy cross-chop, making it a kite-surfing show rather than a paddle session.
There is one humble highlight to speak of, and it’s a long way out, but it’s all we’ve got. On the morning of Wednesday the 16th of September, we finally get a window. The wind swings offshore—true offshore from the West—and things clean up. The swell is coming from the NNE at about 3ft with a short period of 5 seconds, with combined energy of (68), which is weak. It’s not pumping, but the glassy, offshore conditions will make the most of it, offering clean little peelers for a beginner-friendly wave. This is the standout session for the whole period—the only one with surfable waves and clean conditions.
Following that, the morning of Thursday the 17th shows a little more size at 4ft from the East, also with a light offshore wind, but the period is still short at 5 seconds, and combined energy bumps up to (110), which is moderate. It’s a second decent look, but the long wait and the short-period nature of both these swells mean it won’t be mind-blowing. For a more consistent spot like this, a blank run like this is certainly possible, but it’s a bummer. Forecasts can always change, and it tends not to stay flat forever, so keep an eye on it.
For what it’s worth, the water temp is about average for this time of year, so no surprises there.
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.
