The Lowdown
Alright folks, Rusty here. Let's be straight with you, the outlook for Coastguard Beach over the next 16 days is pretty grim. There’s no surf to get excited about at all. We’re looking at a real dry spell.
From Wednesday, August 5th right through to Thursday, August 20th, the swell is tiny. We’re talking ankle-snappers and knee-high slop at best. The biggest reading we get is a mere 2ft to 2ft around Saturday, August 15th, but that’s accompanied by a messy cross-shore wind and a combined wave energy that's still weak (31). For a beach that’s exposed to the SE, we just aren’t seeing any proper swell lines pushing in. The period on most days is short, down around 5 to 8 seconds, meaning no real push or shape to the waves.
Most days are a write-off with “poor surf conditions” flagged throughout. Sure, you’ll get a few windows of clean conditions – like Sunday morning, August 9th with a light offshore wind, or Sunday afternoon, August 16th with glassy conditions – but it's flat as a tack.
There is simply no stand-out surf on offer here. Not a single recommendation. For a beginner-friendly spot, this is a real bummer, but it’s just one of those runs where the ocean has nothing to give. The setup looks more interesting for a kite surfer or a flat-water paddle than a surfer chasing a wave.
Keep an eye on the charts, though. It tends not to stay this poor forever.

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.
