The Lowdown
Alright, groms and gremmies, Rusty here. Let’s look at the 16-day picture for Coastguard Beach, and I’ll tell ya, it’s a tough one. There’s nothing happening for a long stretch at the beginning, so don't even think of paddling out yet.
From now until the morning of September 20th, it’s a full week of flat, weak, and messy nothing. Don't bother.
We finally see a pulse on Monday the 21st with a 5ft swell from the NE, and the energy climbs to a moderate 294. But the wind is cross-shore, and the ocean is ugly—still a poor call. The rest of that week is a battle against onshore winds and chop.
The one, and I mean *the one* time to even consider it, is Friday the 25th of September in the afternoon. The swell drops a bit to 7ft from the ENE, but that’s backed by a nice 12-second period—that’s real groundswell, full of power and grunt. The combined energy hits a massive 2212. The wind goes light from the SE, so it’s a light cross-onshore breeze, keeping the surface clean enough for some fun. This is your standout window. That’s a size that’s for the experienced crew; beginners should sit this one out. The long period will give you good shape, but at a beach break it might close out in spots. The water temp is about normal for the season. If you’re an expert, this is your shot.
After that, the end of the run cleans up with offshore winds on Sunday and Monday, but the swell is small and weak. So, your best bet? Friday the 25th afternoon. Mark it.
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.
