The Lowdown
Alright folks, Rusty here. The next 16 days at Coastguard Beach are looking properly quiet. The model’s got nothing on offer worth paddling out for, so we’re stuck with a flat spell right through till the end of the window. The ocean is basically switched off in terms of surfable waves.
The whole period is a long stretch of small, weak, and messy energy. There’s a slight bump of energy on Sunday the 6th of September when the combined swell energy kicks up to a moderate 259, with a 5 ft swell from the NE, but the wind is a strong cross-shore from the north at 25 mph, chopping it up into a lumpy, cross-chop mess. The model reckons the surf quality is poor, and I’d say it’s more of a kite-surfing setup than a surfing one. The period is only 8 seconds, so you’re not getting any real push or shape out of it.
The water temperature is sitting at 70°, which is a touch warmer than normal for the time of year.
There’s a brief moment on Monday afternoon, the 7th of September, with a clean 2 ft swell from the ENE and a light offshore wind from the west. The combined energy is weak at 88, and the period is 10 seconds, so it’s a little better. But the model calls it “surfable waves but very ordinary conditions” – honestly, it’s still not a session worth chasing.
The rest of the days are full of tiny, wind-screwed, or completely flat conditions. The best you’ll get is a glassy morning on Friday the 4th of September with 2 ft, but the swell is too small and weak to stand up. The last two days show a very long-period groundswell on the 18th of September, with a 12-second period from the ESE, but the swell height is only 0.7 ft, so it’s just a hint on the tide.
This is a tough run. Coastguard Beach is a consistent spot, so this blank run is a bit of a surprise. But forecasts can change, and it tends not to stay this poor for long. For now, save your wax and check back in a few days.
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.
