The Lowdown
Alright, let’s have a look at what’s on the cards for the next couple of weeks.
Honestly, folks, right now the surf is pretty flat and the wind is a pain. There’s a bit of a wait ahead. We’re looking at a solid stretch of nothing much to get excited about for the first week or so. The waves are small, the wind is messy, and nothing’s coming together. The first real chance of a wave happens around Thursday, 31 July at Dumps (Brandon Bay).
That morning, the swell finally shows up. We’re talking about a 3 ft groundswell from the WNW, with a lovely long period of 11 seconds. That’s proper energy moving through, with a combined energy of 349 – solid, moderate wave energy. The wind is light and offshore from the SSE, which means the lineup will be clean and glassy. This is the standout. It’s not huge, but it’s clean, and the kind of day where you just want to be out there. It’s a fairly consistent spot, so expect a few other souls who know what’s up – crowds are possible. The water temp is about average for the time of year, nothing unusual.
Before that, we’ve got a long gap. The Saturday 26 July sees a 10 ft swell roll in, but it’s a total mess. Onshore winds from the NW at 12 mph and a short period of 10 seconds mean it’s blown out and choppy. The combined energy is a massive 1453 – that’s very strong energy – but with the wind tearing it apart, it’s a write-off for paddle surfing. If you’ve got a kite, that setup might actually look interesting, but for a surfboard? Forget it.
The Sunday 27 July and Monday 28 July still have size, but the wind stays onshore, so it’s all lumpy and poor. Not worth paddling out.
Then, after that Thursday morning session, the window closes again. By Friday 1 August, the swell drops right back to 3 ft and the wind turns fresh and messy. The rest of the forecast into the second week stays small, with poor conditions and onshore winds.
So, the one to circle is Thursday 31 July morning. It’s not a monster, but the clean conditions and that long-period groundswell will give you some fun, lined-up waves. That’s your best bet. Everything else is either too small, too windy, or both.
