The Lowdown
Alright, Rusty here, and I’ve just had a good look at what’s coming up for Dumps (Brandon Bay). Let me tell you, it’s a bit of a mixed bag, but we’ve got a few windows that might just make it worth getting wet.
The water temp is sitting right around average for this time of year, so nothing out of the ordinary there. The wind is the real story though, and it’s gonna be a problem for most of the forecast.
The best chance for a decent surf will be early on. Wednesday morning the 12th of August has some small, clean waves. We’re looking at a 3 ft swell from the WSW, with a period of 10 seconds, and a light cross-offshore breeze from the SSE. The combined energy is weak (164), so don’t expect any power, but it’s clean and rideable. If you’re keen, get out then.
After that, things turn pretty ordinary. Most of the week from Wednesday afternoon through to Monday the 17th is filled with poor conditions, cross-onshore winds, and only marginal waves at best. The swell tries to pick up a bit, but the wind just ruins it. On Saturday the 16th, we get a little glassy window in the morning and afternoon with a 3 ft and 2 ft NW swell, but the energy is weak (103 and 74) and the period is short at 8 seconds. It’s surfable, but you’ll be working for it.
Then things get messy. From Tuesday the 18th, the swell really starts to build. We’re looking at a 6 ft swell on Tuesday morning, jumping to 8 ft by the afternoon, and by Wednesday the 19th, it’s a solid 10 ft to 12 ft. The energy is strong (410, 1174, 2033, 2139), but the wind is howling with a near gale from the WNW. This is big, powerful, and completely blown out. This is strictly for experts only, and even then, it’s gonna be a battle. For most, it’s more like a kite-surfing setup than a paddle session.
The swell drops back down towards the end of the week, but we’re still dealing with messy wind and poor conditions. Friday the 21st of August sees a return to some clean, cross-offshore conditions with a small 3 ft NW swell in the morning, but the energy is weak (135). It’s clean, but tiny.
If you’re looking for the standout, it’s the Wednesday morning the 12th of August. That 3 ft WSW swell with glassy conditions is the only time you’ll have a truly clean wave. The rest of the forecast is either too small, too windy, or too big and messy. Keep an eye on the forecasts, but for now, be patient.
Rusty.
