The Lowdown
Alright, Rusty here again. Let's cut to the chase. Coastguard Beach is looking at a long, hard stretch with nothing to offer for the first week or so. A real quiet spell from the start of the forecast all the way through til the 19th of August. It's the kind of flat run that's more normal around here, so don't be too surprised.
The first time we get a sniff of a wave is on the morning of the 20th of August. The swell energy is still weak at 177 (moderate), but it's a groundswell from the east at 4ft with a period of 7 seconds. The wind will be offshore and light, so the water will be clean. The problem is that the swell is out of the east, and this break really needs a south-east wind to work. The surf will be rideable, but it's nothing to write home about. For beginners, 4ft is okay, but the quality isn't there.
The best option, if you can call it that, is the morning of the 20th. It's the only time the forecast gets above "poor." The easterly swell at 4ft with a light offshore westerly breeze at 10 km/h will give you the cleanest wave of the whole period. Crowds are possible, as it's a consistent spot, but with this quality, you might have it to yourself. The water temperature is about average for this time of year, so nothing special.
After that, it's back to the same. The afternoon of the 20th gets a stronger wind but weaker swell, and by the 21st, the energy tanks again. The 22nd of August is a total write-off with tiny 1ft waves and weak energy. So, there you have it. One single, average morning on the 20th. If you're desperate, that's your only shot. Otherwise, leave the board in the shed.
Rusty.
