The Lowdown
Righto, let’s have a look what’s cookin’ over the next couple of weeks at Coastguard Beach.
Honestly, mate, it’s a bit of a flat spell to kick things off. We’ve got a solid stretch of days with barely a ripple worthy of a paddle. From now through to the start of September, you’re lookin’ at tiny, weak conditions – mostly under 2ft and a messy mix of onshore or cross-shore wind. Thursday afternoon on the 3rd does show a little 1ft SE swell sneakin’ in with a period of 9 seconds (got a bit of push there for its size), but the wind is straight onshore, so it’s gonna be messy. Not worth wettin’ a wetsuit for.
Then we hit a lighter patch. By Friday the 4th of September, the wind swings offshore – clean conditions finally – but the swell’s still only around 3ft and the period is short (6 seconds), so those waves are gonna be fat and weak. It’s clean, but it’s not gonna get your heart pumpin’.
Here’s where it gets interesting, though. Saturday the 5th of September morning is the real standout in this whole outlook. We’ve got a clean 4ft ENE groundswell rollin’ in with a long period of 11 seconds and a combined wave energy of 415 (moderate energy). The wind is light offshore from the west – absolutely glassy offshore conditions for Coastguard Beach. This is the morning to be out there. Nice lined-up waves, clean faces, and that ENE direction works a treat for this exposed spot. Keep in mind, it’s an exposed beach, so with a long-period swell like that, it might break a little straight in some spots, but the offshore wind should keep it tidy. It’s a beginner-friendly 4ft, so perfect for anyone lookin’ to get some clean rides. Crowds can be a factor here sometimes, so get in early for the best of it.
Saturday afternoon keeps the same 4ft ENE swell but the wind goes cross-off from the SSW – still clean, but not quite as perfect as the morning. Sunday the 6th of September afternoon also pops up with nice clean 4ft ENE groundswell and glassy wind from the SSW, energy around 301 (moderate). That’s another solid session if you missed Saturday.
After that, the swell drops right back down through the second week, with small 2ft to 3ft ENE pulses and mostly offshore or cross-off winds from the NW. It stays clean but tiny. Not much to get excited about. We even see a glassy 0.5ft day on Friday the 11th of September – beautiful conditions, but you’d be huntin’ for waves.
So, bottom line: if you’re keen, your window is Saturday the 5th of September morning – that’s the pick of the entire 16 days. Sunday arvo is a good backup. The rest is a whole lot of small and average.

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.

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.
