The Lowdown
G'day, Rusty here. Lookin’ at the next 16 days for Portreath Harbour Wall, and I gotta be straight with you—it’s a tough stretch. This reef setup is a bit of a tease; it’s fairly consistent at pickin’ up swell, but the wind and conditions are just not cooperating. The water’s sittin’ at 65°, which is a touch warmer than normal for this time of year, so at least you won’t freeze waitin’ for somethin’ to happen.
The first few days are a write-off. Thursday 30th July has a small 3ft NW swell at 5 seconds, but that 16 mph NNW cross-on wind has it chopped up and messy. Friday 31st and Saturday 1st August are much the same—tiny waves, onshore breeze, and the energy is weak (45 to 68). You’d be better off stayin’ home.
Then Sunday 2nd August mornin’ brings a glimmer: a light SE offshore wind at 6 mph, with a 2ft W swell. The energy is still low (40), but conditions are clean. It’s not a standout, but it’s the first time the wind’s workin’ with us. Monday 3rd August mornin’ is similar—3ft WSW swell, cross-off wind, and a bit more energy (85). The comment says “surfable but very ordinary,” which sums it up.
The real potential, and I mean the only real potential, shows up much later. Saturday 8th August afternoon sees a 5ft SW swell with a 7-second period, and the combined energy jumps to 202—that’s moderate, and the biggest we’ve seen. But the wind is onshore from the NW, so it’ll be a messy lump. Sunday 9th August mornin’ also has some size, 4ft WNW swell, with 203 energy, but again a cross-on wind from the NNE at 12 mph. The size is there, but it’s not clean.
The best chance for a decent session might be Monday 10th August afternoon. A 2ft WSW swell, 10-second period, with a light offshore wind from the SE at 9 mph. The energy is 86, and it’s clean. Still small, but the wind is right. Tuesday 11th August also has offshore winds, with 2-3ft WSW swell and moderate offshore breeze, but the energy is only 71-95.
Overall, it’s a lean couple of weeks. The swell never really fires, and the wind is mostly cruel. The best on offer is probably Monday 10th August afternoon for a clean, small wave, or Tuesday 11th August for a similar setup. If you’re desperate, those are the windows. Otherwise, I’d be checkin’ other spots or waitin’ for a better forecast.
Rusty.
