The Lowdown
Alright, Rusty here. Let's chew the fat on what's ahead. Looking at Coastguard Beach, it's a real bummer of a forecast for the next couple of weeks. The window is basically a write-off, with a long stretch of barely any surf and winds that just won't cooperate.
For the first week, right up to the 15th of September, you're looking at a big fat zero. The swell is tiny and weak, barely hitting 2ft with periods under 10 seconds, so no power or shape at all. The afternoon of the 6th sees a bit of a north-west wind that cleans the surface, but with the energy at just 98, it's a pathetic ripple. Water temp is average for the season. After that, the wind goes onshore or sideshore and the swell flatlines. There's a dry spell of about a week where you can leave your board in the garage.
Come the 16th and 17th of September, there's a little pulse of energy. The swell jumps up to around 5ft from the NE, with energy readings hitting 167 and then 203. That's got some push, but here's the kicker: the wind is shrieking onshore at 20 to 30 mph, making it a lumpy, choppy mess. The period is short, so it's just storm slop. For a beginner spot like this, the 4ft-plus is too much, and the wind just ruins it. This setup looks more fun for kite surfing than paddling out. After that, it drops back to tiny, gutless waves.
Bottom line: there are no standout days here. Your best, and I mean *best*, shot is the afternoon of the 6th for some clean, knee-high nothing. Otherwise, keep your stick dry and wait for a better run of forecasts—they usually roll around eventually.

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.
