The Lowdown
Alright, mate, let's have a yarn about the waves. I've gotta be honest with you—this is a rough run ahead. For the next couple of weeks, we are looking at a real flat spell. There's just nothing on the cards that's going to get the blood pumping. From now all the way through to the end of the window, it's tiny, weak, and messy.
The only break on the radar is Octagon House. It's exposed to the south-east, but the swell we're getting is small, wind-affected, and just doesn't have any grunt. On Thursday the 20th of August, we're looking at a tiny 2ft south swell with a period of only 4 seconds, meaning it's just wind chop with no real power behind it. The combined wave energy is a measly 14, which is as weak as it gets. Winds are cross-shore and choppy, making a messy little dribble. The water temp is 87°, which is about a touch warmer than normal for this time of year, but that's the only thing to get excited about.
Through Friday, Saturday, and into the next week, it's more of the same. Swell heights stay under 2ft, periods hover around 4 to 5 seconds, and the light cross-shore winds keep it clean but totally gutless. The setup at Octagon House is a beach break, and with south swells coming in, it's going to be a dribbly, weak little wave that's hard to get any push out of. It's fine for a beginner to practice paddling, but there's nothing here for anyone looking for a proper wave.
We roll into the end of August and the first days of September, and the swell gets a sniff of life, but it's still no good. On the 31st of August (Monday), we might see a little bump to 3ft from the SSE, but the wind is cross-onshore and we've got some thunderstorms around. The period is still a short 4 seconds, so it's all chop and no shape. The energy gets up to 34, which is still very weak. Nothing to drive out for.
Looking at the last few days, into the start of September, the swell direction tries to shift from the east and northeast, but the heights are still tiny, the periods are short, and the wind is either cross-onshore or straight onshore. It's a real tough stretch of flat, lifeless ocean.
Honestly, mate, this is one of those quiet periods where you might as well wax the board, check the fins, and wait for the next proper groundswell to roll in. There's not a single standout session in the whole 16 days. The best thing I can say is that it's consistent in its inconsistency. It's a quiet time of year, and this looks like a normal blank run for this area.
So, for the long and the short of it: save your energy, maybe chase a sunset, but don't chase these waves.
