The Lowdown
Alright, Rusty here. Let’s have a look at what’s on the cards for Dumps.
Right, straight up, I’ve got to be honest with you – this 16-day window is looking pretty bleak. We’ve got a long stretch of poor quality surf, and it’s going to take a while before we even see anything that’s worth getting excited about. For the first week, from Monday the 20th right through to Sunday the 26th, it’s basically a write-off. We’ve got tiny swell, weak easterly or northerly winds, and dirty, short-period bumps. The forecast is consistently throwing up scores of zero for the first ten days or so. The combined energy from all swells is weak, starting at just 89 on Monday morning and staying in the double digits until the weekend. It’s a total flat spell.
Things start to look a little different towards the end of the month, but it’s still not for the faint-hearted. From Friday morning the 31st of July into early August, we see some swell pushing in, but the conditions are a mixed bag. The standout – and I mean the only real chance to get wet – looks to be Friday the 24th of July. The morning is the pick, with a clean 4 ft of NW swell pushing in on a light 6 mph breeze. The swell period is a decent 10 seconds, which should give it some shape, and the wind is blowing directly from the west, which is an offshore wind for Dumps, so that will keep the surface nice and clean. The combined energy is at 285, which is still moderate, but at least it’s something. The afternoon gets messier as the breeze swings WNW and picks up, so you’ll want to be out early. The water temp is just about average for the time of year.
After that, the following Saturday and Sunday (the 25th and 26th) see a jump in size, with 7 ft to 8 ft of WNW swell, but the wind turns onshore and howls from the NW at 19 mph, creating a fresh, lumpy mess. The combined energy spikes to 938 and 1125 – that’s a lot of juice, but with that onshore wind, it'll be a roiled-up, ugly beast. That's expert-only territory and probably more fun for the kite crew than the paddle crew because the onshore wind and that 8 ft size will make it a washing machine at a beach break. The truth is, aside from that one window on Friday the 24th, there’s very little to recommend.
This is one of those blank runs that’s pretty normal for the area when the winds don’t align. Stick to the Friday morning session if you can, and keep an eye on the forecasts for a change.
Rusty.
