The Lowdown
Alright, Rusty here, let’s break down what’s coming for the next couple of weeks.
Honestly, Devonport Rivermouth is looking pretty flat and bleak for a long while. This is an inconsistent point/river break, and it’s showing it. We’re staring at a big gap of poor or no surf from now all the way into the first week of August. The water is 56°F, which is about average for this time of year, nothing to write home about.
The first real sign of life doesn’t pop up until Thursday, August 6th. That’s more than a week out, so don’t book your flights yet. But on Thursday morning, we’re looking at a 7ft swell from the NNW with a 7-second period and a combined energy of 383. The wind is light and cross-offshore from the SE, so it’ll be clean. That’s your best bet for the whole run. Thursday afternoon is even better: the wind goes glassy from the NNE at just 3 mph, and the swell holds at 7ft from the NW with an 8-second period. The combined energy jumps to 831, which is proper. That NW swell is the optimum direction for this spot, so it should be lining up real nice.
After that little burst, it drops off again. Friday, August 7th, and Saturday, August 8th, are back to tiny, weak groundswells and messy wind. Friday morning has a 1.0ft NW swell with a 14-second period, but the energy is only 60, and the wind is light cross-shore. Not worth it. The wind gets glassy again Friday afternoon, but the swell is still puny at 1.0ft. Saturday sees a 3ft WNW windswell with a short 4-second period and onshore wind, so it’ll be choppy and ugly.
So, the long and short of it: you’ve got a long wait. The only day that really fires is Thursday, August 6th, especially the afternoon glass-off with that 7ft NW swell. That’s the one to remember. The rest is a whole lot of doldrums.
Rusty.
