The Lowdown

Alright mate, Rusty here. Let’s have a proper look at what’s on the cards for Coastguard Beach.

Straight up, I’ve got to be honest with you—this is a tough stretch. The forecast window is 16 days long, and there’s not a single recommended session in the whole run. The first few days are a write-off with tiny swell, barely a ripple. From Sunday 23 August right through to the end of the first week, we’re looking at swell heights mostly between 0.7 ft and 1 ft, with the odd 2 ft or 2 ft popping up. The wave energy is real weak, barely registering with values like 22 (combined energy of all swells directed here), and it stays that way for days. You’ll get some clean-looking conditions on Monday 24 August morning with a cross-offshore breeze, but the swell’s just too small to push anything worth paddling for.

The water temperature is sitting at 69°, which is 2° warmer than the long-term average for this time of year—nothing unusual, just a normal summer water temp.

Midway through the second week, things start to look a bit more energetic. On Wednesday 2 September, we see a jump to 5 ft swell from the northeast, with the combined energy hitting 206 and 211—moderate energy now, but the wind is onshore or cross-shore, and the conditions are still described as poor. The swell direction is northeast, but the optimum swell direction for Coastguard Beach is southeast, so it’s an awkward angle. The period is short too, around 6 to 7 seconds, which means the waves will be weak and crumbly with no real punch.

The energy keeps building into 4 September, with a 4 ft northeast swell at 9 seconds in the morning (energy 341), and then a 3 ft swell from the southeast at 12 seconds in the afternoon (energy 420). That’s the strongest energy we see in the whole period, but it’s still not making the call for a good surf. Crowds are noted as “sometimes” at Coastguard Beach, but there’s nothing to crowd anyone in this window.

The period to watch is late in the second week, around 4 September, when the swell direction shifts to southeast and the period stretches to 12 seconds—that’s a better angle for the break and a longer period groundswell, which can mean more energy in the water. But the wind is cross-shore, so it’s not clean, and the overall wave comment is still “poor surf conditions.”

Honestly, the whole 16-day window is a blank run. There’s no standout session, no day to circle on the calendar. For a spot that’s usually consistent, this is a quiet spell. In conditions like this, with bigger swell and messy wind, the setup at Coastguard Beach—a beach break—might actually be more interesting for kite surfing than paddle surfing.

Keep an eye on the forecasts, because things can change quick, but right now, I’d say leave the board in the car and go for a walk instead.

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.
