The Lowdown

G’day, it’s Rusty here. Let’s be straight with you: the next couple of weeks are looking pretty bleak for a proper surf. We’ve got a run of tiny, weak surf and mostly average conditions ahead. There’s a long gap at the start with nothing worth paddling out for, so don’t rush to wax up. The waves stay small and poor for the first several days.

Thursday the 6th and Friday the 7th are complete write-offs. We’re looking at ankle-biters at best, with swell around 0.3ft to 1ft, periods of 6 to 9 seconds, and winds that are cross-offshore. The energy is dead weak (4 to 11). You’d be chasing whitewater. Saturday the 8th is no better, with a bit more breeze making it messy.

We do get a slight bump Sunday morning the 9th. There’s a 1ft swell with a 7-second period, but the standout here is the offshore wind. It’s blowing off, light, and the surf is clean. It’s still tiny, but if you’re desperate for a knee-high dribble, that’s your window. The energy is still weak (10). After that, it’s back to the doldrums through the middle of the week. Monday the 10th has light cross-onshore winds, and the swell drops back to next to nothing.

The weekend of the 16th and 17th remains poor. There’s a glassy morning on Sunday the 16th, with 0.3ft swell and 8-second period, but there’s just no power behind it (5). You’d be floating around waiting for a ripple.

Here’s the one glimmer of hope in this entire stretch: Wednesday morning the 19th of August. The swell jumps to 3ft, with a 7-second period from the SW. The energy is still weak, but it’s the biggest we’ll see, and the wind is a moderate cross-shore, which will keep it lumpy. The direction is a bit off for this spot, but it’s the closest to a real wave we get. Still, it’s pretty marginal.

We’ve got a longer gap before anything else of note. Heading into the final days, Friday morning the 21st shows a 3ft swell with a short 5-second period from the NE. The energy is up a bit (43), but the wind is cross-onshore, making it choppy. This is a mess. Given the size, the onshore breeze, and the beach setup, this looks more interesting for kite surfing than paddle surfing.

In short, there is nothing on offer that qualifies as a proper surf. The spot is a consistent beginner break, but the swell stays below 3ft for the entire forecast. It’s a flat spell, plain and simple. Water temp is about average for this time of year. Keep the board in the car and check back later – it tends not to stay this poor for long.

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.
