The Lowdown
Alright, Rusty here again, in feet, miles, and Fahrenheit for you.
So, looking at the whole sixteen days, it’s a slow grind. The beginning is mostly flat, with poor conditions day after day. The only break in the pocket is right at the end.
Coastguard Beach is the only spot in the mix. It’s open, exposed, and takes whatever the ocean offers.
Starting Thursday 27 August through the first week and into the second week, wave heights are tiny—between about 0.3 ft and 3 ft—with weak energy and messy wind. A lot of cross, cross-on, and even onshore wind, which means bumpy, choppy water. The water temp is around 70°, which is a little warmer than the average for this time of year, so that’s comfortable, but the surf is just not cooperating.
The one moment to keep an eye on is Friday 11 September. That morning we see a bump to about 4 ft from the east, with a short period of 7 seconds. The combined swell energy hits 221, which is moderate. The wind turns to a clean cross-off breeze, meaning the face of the wave will be smooth. That morning session is your best bet by a long shot. It’s still a beginner-friendly break, but clean waves and chest-high swell make for a fun paddle. The afternoon gets a bit breezier, so get in early.
If you only get one chance in the next two weeks, make it Friday 11 September morning.
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.
