Alright crew, Rusty here. Let's break down what's happening at Dumps (Brandon Bay) for the next couple of weeks. It’s a fairly exposed NW spot that’s fairly consistent, so we’ll get pulses of swell, but the wind is going to be the deciding factor, and for the first week, it’s a real headache.
Right now, we're starting flat. The first week is looking pretty miserable, to be honest. Our first real chance doesn't come until the morning of Tuesday, July 7th. The water temperature is a touch warmer than normal for the season at 61°, which is a nice welcome.
Tuesday, July 7th morning is the one to remember. We've got a clean 4ft swell from the WNW with glassy wind. Absolutely glassy. The combined energy is moderate at 538, and the period is a solid 9 seconds – not a long-period groundswell, but enough to push in some proper lines. This is the session to lock in. Dumps can get crowded sometimes, so get in there early.
The rest of that week is a mixed bag of cross-onshore breezes keeping things ordinary. Thursday morning the 9th is another glimmer, with another 4ft from the W going glassy – a solid backup if you miss Tuesday. The energy is still there at 301.
We see some more size from the NW on Friday the 10th morning, 5ft with a longer 11-second groundswell, but the wind is cross, making it a tricky read. By the afternoon, the wind jacks up cross-on to 12 mph, so that window slams shut. The 10th into the 11th brings rain and more wind, so don't even think about it.
The swell drops off a cliff from the 12th. The second week is weak. Look at the energy numbers – they drop down to double digits from July 15th onwards. There's barely a ripple. The period drops to 7 or 8 seconds, the swell dips below 2ft, and it's just not worth the effort. There's a potential clean wave on the 13th morning with a 3ft W groundswell at 10 seconds, but it’s tiny (combined energy of 152). That's the best the second week can offer.
So, bottom line: there’s a clear gap of over a week without any real recommendation after the 10th. The only true standout is the morning of Tuesday, July 7th. Get on it.
Rusty.
