The Lowdown
Right folks, Rusty here. Let’s be straight with you – the next couple of weeks are looking pretty grim for a paddle. We’ve got a long stretch of small, weak swell and mostly average winds, so don’t get your hopes up for any proper sessions.
The forecast kicks off on Wednesday the 5th of August at Coastguard Beach. That's a beginner-friendly, exposed beach break. We’re looking at tiny 1ft swell coming out of the SE with a short, weak period of 6 seconds. The wave energy is basically nothing (20), and it’s a cross-offshore breeze. The water is sitting at 68°, which is bang on average for this time of year, so no surprises there. Still, it’s poor surf all day.
We go through a flat spell from Thursday the 6th right through to Monday the 10th of August. Swell is either non-existent or barely a ripple, with heights under 1ft and energy readings in the single digits. Winds are mostly cross-off or light, but there’s just nothing to work with. It’s a real struggle.
Things perk up a touch on Sunday the 9th of August in the morning. The swell is still only 1ft from the SSE, but we get a proper offshore wind from the W at 9 mph. That makes it glassy and clean, but the swell energy is only 16 – it’s still a knee-high dribbler at best. Not worth getting wet for.
The flatness continues through the week. Tuesday the 11th has a morning window with a light offshore, but the swell is only 1ft on a short period. It’s still poor.
Now, we jump out to the tail end of the forecast. Monday the 17th of August is the only real standout, and even that’s a long shot. The morning sees a slight bump to 3ft from the SSE with a period of 8 seconds, and the energy finally climbs to 89 (moderate). But the wind is onshore from the E at 9 mph, so it’ll be messy. The afternoon gets a bit bigger at 4ft from the S, but it’s a short-period chop with onshore wind. It’s not great, but it’s the biggest we get. For a beach break, this setup looks more interesting for kite surfing than paddle surfing.
After that, Tuesday the 18th and Wednesday the 19th offer a bit of clean-ish 1ft SE swell with light offshores, but it’s tiny. Thursday the 20th is back to 0.7ft.
Honestly, there’s no standout quality in this window. The only day with even a hint of size is the 17th, and it’s blown out. If you’re desperate, keep an eye on that morning, but don’t expect much.
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.

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.
