The Lowdown
G’day, Rusty here. Look, I’ll be straight with you – this stretch is a quiet one for Coastguard Beach. It’s a consistent, exposed beginner-friendly spot, but the swell window just isn’t firing for the next couple of weeks.
We’re kicking off with a long dry spell. From Sunday the 23rd of August right through to Friday the 28th of August, it’s flat to tiny. Swell heights are barely cracking 1 ft, mostly from the east and southeast, with periods so short (6-8 seconds) they’re just wind slop. The water is 69°, which is about average for this time of year. The wind is mostly cross-off or cross-onshore, but the energy is weak – combined energy readings are down in the teens and twenties (22, 20, 32). It’s just not worth paddling out.
Friday the 28th of August morning shows a tiny pulse – 2 ft from the south, period 7 seconds, with a combined energy of 95. Still weak, and with a risk of thunderstorms, it’s a hard pass. The next glimmer comes on Monday the 31st of August afternoon. The swell picks up to 2 ft from the east, but the period jumps to 16 seconds – that’s a long-period groundswell. Combined energy hits 222 (moderate). The wind is cross-off at 12 mph, so it’ll be clean. For a beginner spot, that long period might make for some lully waves, but it’s the best we’ve seen in a week.
After that, we hit another quiet patch through the first week of September. Tuesday the 1st and Wednesday the 2nd are poor – cross-onshore winds and weak, short-period swell. Thursday the 3rd sits in the same boat with moderate rain.
The standout arrives on Saturday the 5th of September. The afternoon session is the real deal. We’ve got 2 ft from the east-southeast with a period of 13 seconds (groundswell), combined energy of 215 (moderate). The wind is light northwesterly, cross-off, and it’s clean. For a beginner break, that’s tidy. The swell direction is southeast, and the optimum for this spot is southeast, so it’s dead on.
Then on Sunday the 6th of September, the afternoon glass-off is worth a mention. The swell drops to 2 ft from the east, but the period is 12 seconds and combined energy is 229. The wind is glassy – light northeast at 3 mph. That’s some of the cleanest conditions you’ll see. It’s a small-wave day, but with that period and glass, it’ll be fun.
Overall, the best bet is Saturday the 5th of September afternoon for the best combo of swell size, direction, and clean wind. The Sunday afternoon glass-off is a solid second choice. The rest of the window is flat or blown out. Don’t hold your breath earlier.
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.
