The Lowdown
Alright, grab a coffee, ‘cause the first solid window of surf here at Coastguard Beach is a long ways off. We’ve got a real dead run up until the second week of September. From now ‘til around September 2nd, it’s all knee-high dribble and junk wind. No point even waxing the board.
The action–if you can call it that–starts to flicker on Wednesday September 2nd. It’s a cloudier morning with a small pulse from the SE around 2ft at 11 seconds, but with onshore winds it’s just messy. Not your day.
Thursday September 3rd sees a bump in size up to 5ft from the south, but it’s tied to a howlin’ onshore gale at 28 mph. That’s not surf for paddling, that’s kite-foilin’ territory. The combined energy reaches 190 so there’s power, but the surface is blown right out.
Then there’s another quiet stretch through Sept 4th to the 8th – wind loves spoiling the party, keeping everything small and onshore.
Now, here’s where it gets interesting. Mark your calendar for September 9th. Coastguard Beach gets a pulse of 3ft from the SSE, but check this out: it’s a long period groundswell at 14 seconds, and the wind goes *glassy*. That is a rare treat. The combined energy runs up to 302, which is solid. The waves will be clean and lined up fun for the experienced surfer. The water temp is sitting at 70°, which is a touch warmer than normal for this time of year. Just keep in mind that swell direction (SSE) is slightly off the break’s optimum (SE), so it won’t be its absolute peak, but with glassy conditions, that’s the standout day on the entire 16-day chart.
There’s a blink on Wednesday the 2nd with a small spike – a 2ft SE swell, 11 seconds, and 118 in combined energy, with cross-off winds. But it’s still nothin’ compared to that glassy 9th.
Bottom line: wait it out and get ready for that Wednesday September 9th. Anything before is either flat or blown to pieces.

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.
