The Lowdown
Alright mate, let me break down the outlook for Coastguard Beach. Truth is, it’s looking dead flat for the foreseeable. The water’s sitting around 72°F, which is a touch warmer than normal for this time of year, so hanging in the lineup wouldn’t be cold, but there’s nothing to ride.
The first week is pretty much a washout. Swell heights are tiny – we’re talking about 0.3ft to 1ft, with weak energy readings (most under 20). The wind is clean at times, like early Tuesday and Thursday with offshore breezes, but there’s just no power behind it. Not worth the paddle.
Then on Monday the 17th, a little pulse of south swell shows up, pushing the height to about 4ft, and the energy bumps to 176 – that’s moderate energy. The wind turns offshore from the northwest, so it would look clean. But the period is short at 7 seconds, and the quality is still marked poor. For a beginner spot, 4ft is getting a bit chunky, but that short period will make it fat and crumbly.
After that, it’s back to the doldrums. Swell heights drop back to under 2ft for the rest of the run into late August. You get some clean, offshore windows on the 20th and 22nd, but the swell is just too weak to do anything with.
For a beach that’s usually pretty consistent, this is a grim stretch. But hey, it never stays flat forever, and the forecast can always change.

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.
