The Lowdown
Right, let’s talk Dumps (Brandon Bay). The water’s sitting at about 64°F, which is a touch warmer than usual for this time – nothing wild, just a nice little bonus.
First few days are a total washout. Friday the 28th has a tiny 2ft swell from the WNW with a short 7-second period, but the onshore wind and poor conditions mean it’s not even worth paddling out. Saturday and Sunday the 29th and 30th stay poor – tiny swell, choppy, cross-onshore wind. Leave the board at home.
Monday the 31st shows some life. Swell picks up to 5ft from the west, period stretching to 10 seconds, and the energy is moderate. Morning wind is light onshore, so it’s not perfect, but there’s a little hope. Then Tuesday and Wednesday get messy again with stronger wind and shorter period swell.
The real action starts in the first week of September. Thursday the 3rd has a solid 8ft swell from the WNW with a 10-second period, and the energy is strong. Wind is onshore, so expect some chop, but the size is there. Friday the 4th is the monster: 12ft swell from the WNW, period hitting 11 seconds, and the energy is through the roof – over 2700 in the morning and over 3700 in the afternoon. That’s a huge amount of water moving. But the wind is a fresh 19 mph onshore breeze, so it’s going to be a chaotic, powerful mess. Experts only. If you’re not one, stay on the sand.
Saturday the 5th is the one to circle. Swell drops to 8ft from the NW, but the wind swings to a cross-off SSE breeze at 12 mph, and conditions are actually clean. The energy is still very strong at over 1500. This is your best window for quality, powerful waves in this whole outlook.
After that, it’s back to poor. Sunday the 6th is junk, Monday the 7th brings a 10ft swell with strong onshore wind, and Tuesday the 8th goes absolutely nuts: 20ft swell from the WNW, period 11 seconds, and energy over 8000. But it’s cross-onshore at 25 mph, so it’s a total washing machine for paddle surfers. Kite surfers will be in heaven.
The last few days, from the 9th to the 12th, are mostly ordinary. There’s a clean window on the afternoon of Wednesday the 9th with a 4ft swell and cross-off wind, but it’s only marginal. A few small clean moments on the 10th and 11th, but nothing that’ll get your heart racing.
Best bet: Saturday morning, September 5th. That’s your clean, powerful stand-out. Friday the 4th is for the big wave chargers only. Everything else is a waiting game.
