The Lowdown
Alright folks, Rusty here. Let’s get into it for the Dumps at Brandon Bay.
It’s gonna be a tough slog for a while. We’re looking at a solid week of messy, poor conditions before we get anything worth paddling out for. The northerly and westerly winds are going to be a pain, keeping things choppy and onshore. The first real chance of a wave comes Monday, August 10th, but even then we’re only talking about small, ordinary surf. The swell is tiny at 3ft from the NW with a weak period of 8 seconds, and the combined energy is a low 177. It’s glassy in the morning, so the surface will be clean, but there’s just not enough grunt to get excited about.
The real interest, and the only standout on the horizon, is a big pulse of swell that arrives on Tuesday, August 18th. The wind goes light and the swell jumps up to a solid 12ft from the WNW with a period of 9 seconds. The combined energy is a massive 1741, which is a very strong punch of water. This is the top of the menu for the whole outlook. The wind is light onshore, so it might be a bit lumpy, but for experienced surfers, the power will be there. However, at 12ft, this is definitely for experts only – beginners should stay well clear. The 9-second period means it’s a mid-period swell, so it’ll have some push but won’t be too drawn out. The water temperature is about average for the time of year, so no need to worry about a wetsuit just yet.
After that, the swell drops and the wind whips back up, making a mess of things right through the end of the period. Thursday, August 20th morning sees a tiny glassy 2ft wave, but it’s just too small to be a proper session. The next bump on Friday, August 21st sees 8ft swell from the WNW, but the wind is a cross-shore 12 mph, creating a chop that mixes things up.
So, the call is simple. The first week is a write-off. Wait for that big, powerful swell on Tuesday, August 18th. That’s your window. It’s a big, expert-only wave, but it’s the only real pulse of energy in the whole 16 days. The water is about average for the time of year at Dumps.
Rusty.
