The Lowdown

Alright, Rusty here. Let’s have a look at what’s on offer over the next couple of weeks.

Right off the bat, I gotta be straight with you: this is a lean stretch. Coastguard Beach is the only break in the game, and honestly, it’s a tough one to get excited about. The whole 16-day window is a real grind. For the first 11 days, from now through to the 18th of August, it’s pretty much a write-off – the swell is tiny, mostly 0.3 ft to 2 ft, and the energy is weak, with combined energy values sitting mostly between 1 and 22. It’s just not doing anything. There’s a big gap of nothingness until we start to see a flicker of life.

That flicker finally shows up on the morning of Wednesday, 19 August. We get a small lift to 1 ft from the ESE, with a period of 14 seconds – that’s a proper groundswell, which is promising for shape. The combined energy climbs to 69 (moderate), and we’ve got a clean, cross-off wind from the SW at 9 mph. It’s surfable, but very ordinary. The water temp is about average for the time of year, nothing wild.

The morning of Sunday, 23 August is the one to circle on the calendar. This is the best of a very quiet bunch. We’re looking at 2 ft from the E, with a 13-second period and the combined energy jumping to 322 (strong). That’s the most power we’ll see all window. The wind is a moderate cross-off from the SW at 12 mph, keeping things clean. It’s a marginal call, but it’s the only window where you might actually get a couple of decent ones. For a beginner spot, that 2 ft is fine, but it’s not big enough to worry anyone.

The rest of the days after that are just more of the same – small, weak, and onshore or cross-shore. It’s a long, quiet run for Coastguard. We’ll just have to wait and see if the forecasts change.

Rusty.

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.
