The Lowdown
Alright folks, Rusty here. Let's have a look at what's on the cards for Coastguard Beach over the next couple of weeks.
Honestly, it’s a tough stretch ahead. The forecast is showing a real flat spell with barely a ripple worth paddling for. The water’s a touch warmer than usual for this time of year at 70°F, which is nice, but it’s not going to help the waves.
We kick off on Friday, August 28, with tiny 2ft swell from the ESE, but it’s just not got any push. The cross-off wind is okay, but the energy is weak (51), and it’s just poor. That sets the tone for the whole first week. Saturday and Sunday are even smaller, with wind swinging around and messing up what little is there. From Monday, August 31 right through to the end of the first week, we’re looking at scraps of swell – 0.7ft to 1ft – and wonky, short-period windswell that’s barely breaking. The combined energy readings are all in the weak zone, mostly under 50. There’s nothing to get excited about.
We hit a bit of a bump on Monday, September 8, during the afternoon. There’s a 2ft swell from the SSE with a long period of 11 seconds, and a light offshore wind from the WNW. The energy ticks up to 71 (moderate), and it’s described as "surfable waves but very ordinary conditions." That’s the best we’re going to see in the whole 16-day window, and it’s still pretty ordinary. It’s the only time the score lifts above a zero. For a beginner spot like Coastguard Beach, that’s small and clean, but even then, it’s not a standout.
Beyond that, the forecast gets even more inconsistent. The rest of the second week stays tiny, with weak energy and onshore winds ruining the few attempts at a wave. The 12th of September sees a bit more size at 3ft, but it’s onshore and choppy, so it’s a no-go.
There really isn’t a standout session here. The only real mention is that Monday afternoon on the 8th of September, with a clean, offshore breeze and a touch of period. But for a break that’s normally consistent, this is a barren run. It’s one of those times where the forecasts might change, so keep an eye on it, but right now, I’d be leaving the board at home.
Rusty.

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.
