The Lowdown
G’day, Rusty here. Look, I’ve gotta be straight with you – this stretch of coast is having a shocker. We’re looking at a solid 16-day window, but don’t get your hopes up because the first 13 days are a complete write-off. From the 5th of August right through to the morning of the 18th, every session is rated as poor surf conditions. That’s nearly two weeks of flat, weak dribble with no energy to speak of. Nothing’s breaking, nothing’s worth paddling out for. It’s dead.
Now, you might be thinking there’s a glimmer of hope, and you’d be right, but it’s a small one. The only half-decent opportunity shows up on the morning of Tuesday the 18th of August. Coastguard Beach is a beginner-friendly, exposed spot that’s consistent, with a SE direction being the optimum. The swell direction is coming from the east, which is a bit off-angle, but it lines up okay. The swell height is a meagre 4 ft, but the period is a short 8 seconds, so it’s not going to have much push. The combined energy of all swells here is moderate at 236, so at least there’s a bit of life in the water. The wind is a light cross-shore breeze from the south at 6 mph, which will keep the surface clean-ish, but with a short period and a bit of cross-chop likely, it’s not going to be epic. The water temp is about average for this time of year, so nothing weird there.
The afternoon of the 18th and the 19th shows a bit of waist-high slop, but the wind picks up and the energy drops again, so don’t bother. This is a beach setup, so with the poor quality and onshore winds, it’s looking more like a kite surfer’s playground than a paddle surfer’s dream. The entire run is a blank, and that’s just how it goes here sometimes. Forecasts can change, but for now, save your energy.
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.
