Table - best surf conditions forecast for Octagon House over the next 16 days.
Alright folks, Rusty here. Let’s have a look at what’s on offer over the next couple of weeks.
Right off the bat, I’ll be straight with you – this is a pretty grim stretch for a surf. The entire 16-day window is basically a write-off. We’ve got a solid 14-day gap from the start with no surf worth paddling for. The only glimmer of hope shows up on the 24th of July, but it’s a fleeting one.
The swell is tiny and weak across the whole period. Most of the time we’re looking at 1 ft to 4 ft of short-period, onshore windswell coming out of the SSE to SE. The wind is almost never in our favour, usually blowing onshore or cross-onshore, which just trashes what little bump there is. The water temperature is around 87°, which is a touch warmer than normal for this time of year.
Now, the one day that might get your attention is Friday the 24th of July. At Octagon House, the morning shows a bit of a pulse. The swell is coming from the South at 4 ft (moderate energy, 102), with a period of 6 seconds, and the wind is a clean, cross-offshore breeze from the WSW at 9 mph. It’s still not great, but it’s the only time in the whole outlook where the conditions are clean enough to get wet. The water is still warm, but we don’t have a temp reading for that specific day. Even then, the waves are small and weak, so don’t expect much. Crowds are possible here, but given how poor the forecast is, I doubt there’ll be many takers.
After that, it’s straight back to onshore junk and tiny swell for the rest of the window. Honestly, this is one of those stretches where you’re better off leaving the board in the shed. The setups here are more interesting for kite surfing than paddle surfing on most days.
Rusty.
