The Lowdown
Alright folks, Rusty here. Let’s have a look at what’s cooking for the next couple of weeks.
To be honest, it’s a grim start. We’re looking at a long, quiet run with nothing worth paddling out for from Saturday the 1st right through to the middle of the month. The swell is tiny, the wind is messy, and the Nera Rivermouth is just not doing anything for us. Saturday the 1st has some 3ft swell from the SSW, but with a 19 mph cross-on shore, it’s just a lumpy mess. Sunday the 2nd is flat as a tack. Monday the 3rd teases with a clean morning but only 0.3ft of swell – that’s not even a ripple. The whole first week is a write-off; the wind is mostly cross-shore or cross-on, and the energy is weak. The combined energy on the 4th of August hits 415 (moderate), but the cross-shore wind kills it.
The best chance we get is on Sunday the 16th of August. The morning looks like a proper standout. We’ve got a solid 6ft swell from the SSW, with a really long period of 20 seconds – that’s groundswell energy, and it’s clean with a light cross-offshore breeze. The combined energy is a massive 2583, which is very strong. This is for experienced surfers only, as it’s over 5ft. The long period will make it punchy and better for the river mouth setup, but it might be a bit straight for the beach sections. The water temperature is 73°, which is about average for this time of year, so no worries there.
The afternoon of the 16th drops off a bit with the wind picking up to 19 mph cross-shore, making it lumpy and less appealing. The 15th of August has some size (5ft), but the wind is cross-shore again, so it’s not clean.
Honestly, for the whole 16-day window, there’s only one real window worth chasing. The Nera Rivermouth is an inconsistent spot, so this blank run isn’t unusual. Keep your eye on the 16th of August morning – that’s the one to get excited about.
Rusty.
