The Lowdown
Right, grab a coffee. Let's take a look at the 16-day rundown for Dumps here in Brandon Bay. It’s a bit of a mixed bag, with a long stretch of poor conditions right out of the gate.
The first few days are a write-off. We’ve got nothing until the 13th of September. The wind is a problem, and the swell is just messy. The first real glimpse of something decent shows up on Sunday morning, the 13th. The swell is a clean 5ft from the NW with a period of 11 seconds, which is a nice long groundswell. The wind is light and cross-off from the SSE, keeping the surface clean. The combined energy is moderate at 698, and it’s looking like a proper session. The water is a touch warmer than normal at 62°F, so no need for a thick wetsuit.
That Sunday morning is the best of the early run. After that, we slide back into a stretch of choppy, onshore slop until the 22nd of September. It’s a proper dry spell, nearly a week of nothing worth paddling out for.
Then, the forecast gets interesting. The standout is the afternoon of the 23rd of September. The swell pushes up to 8ft from the WNW with a long 11-second period, generating a very strong combined energy of 1359. The wind is light and cross-off from the SSE, making for clean, lined-up waves. This is for experienced surfers only, as it’s a solid size. The morning of the 23rd is also good, with clean 5ft waves, but that afternoon is the absolute pick of the window.
The last day, the 24th of September, looks promising too. Both the morning and afternoon offer good, clean conditions with cross-off winds and waves around 5ft to 6ft.
So, to sum it up: the first week and a half is a long wait for little reward. The 13th of September gives you a taste, but hold out for the 23rd of September. That afternoon is the one that’ll get you out of the office.
