Table - best surf conditions forecast for Coastguard Beach over the next 16 days.
Alright folks, Rusty here. Let’s cut through it. This is a quiet stretch for Coastguard Beach. We’re looking at a long, flat spell upfront, with no real surf to speak of for the first two weeks. The whole run is pretty much a bust, so don’t get your hopes up for a quick fix.
The first couple of weeks through July are a write-off. Tiny, weak swell, most of it under 1ft, and the wind is all over the place – cross-onshore, cross, cross-off… nothing that’s gonna line up a proper wave. The energy is almost non-existent, with values like 14 (weak energy) and 5 (weak energy). There’s a few moments of clean conditions with offshore wind, like Wednesday morning the 15th, with a gentle offshore and 1ft swell from the S, but it’s just too small to get excited about.
We finally get a pulse of energy rolling in on Sunday the 26th. The morning shows a 3ft swell from the SE, with a period of 10 seconds, and it’s got a bit of grunt behind it – combined energy of 122 (moderate wave energy). The wind is a clean cross-off from the WSW at 15 km/h. It’s surfable, but it’s nothing to call home about. The water temp is sitting at 19°, which is about average for the time of year.
Then Sunday afternoon the 26th the swell jumps to 5ft from the S, with a period of 10 seconds, and the energy spikes to 414 (strong wave energy). That’s the biggest we’ll see, but the wind is a fresh 30 km/h cross-off from the SW, making it a bit of a handful. At 5ft, it’s starting to push into too big for beginners territory, but for the average surfer it’s still doable.
If you’re desperate, that Sunday morning the 26th is your best bet – but it’s a long way off, and forecasts change. Otherwise, pack your board away for a while. This is a bleak run, and it’s pretty normal for the area to have stretches like this. Keep an eye on the charts, but for now, it’s a big old flat spell.
Rusty.

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.
