The Lowdown
G’day, Rusty here. Look, I’ll be straight with you – this stretch of coast is going through a flat spell. For the whole 16-day window, we’ve got next to nothing on offer. The first surf recommendation doesn’t show up until the very end of the run, and even then it’s barely a pulse. We’re looking at a long gap of over a week and a half with no real surf to speak of. The combined swell energy figures are mostly in the low two-digit range, sometimes dipping into single digits, meaning the ocean is basically asleep. It’s a quiet period for the area, but forecasts can change, so don’t write it off completely.
The only break in the mix is Coastguard Beach. It’s a consistent, exposed beach break that’s best for beginners, and the optimum swell direction is SE. Through the entire forecast, the swell is tiny – we’re talking 0.3 ft to 2 ft most days, with the odd pulse pushing 5 ft on Wednesday the 2nd of September morning. That’s the biggest we see, but it’s an onshore wind, ESE at 16 mph, making it messy. The combined energy hits 137 (moderate) that morning, but it’s not clean. The period is short at 6 seconds, so it’s weak and bumpy. Not really worth paddling out for.
There’s a moment late in the run that stands out just a little. On Friday the 11th of September, the afternoon turns glassy with a slight air (SW 3 mph) and clean conditions. The swell is only 1 ft from the SE with a period of 9 seconds, and the combined energy is 36 (weak). It’s tiny, but if you’re desperate and have a log, you might get a few knee-high ones. The water temperature is about average for the time of year. Crowds are possible here, but with surf this small, you’ll likely have it to yourself.
The rest of the time, it’s mostly cross-off winds or light breezes, but the swell just isn’t there. The biggest issue is the lack of energy – even when the wind is good, the waves are too small to ride. Nothing here for a surfer to get excited about. The best advice is to wait for the next system. Keep an eye on the forecasts – it tends not to stay this flat for long.

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.
