The Lowdown
G'day, it's Rusty here. Let's have a look at what's on the table for Long Strand–Castlefreke.
To be straight with you, the 16-day window is looking pretty grim. We've got a long run of small, messy, and mostly onshore slop with no real quality on offer. The water's sitting at a much warmer than normal 66°, but that's about the only highlight. The best you can hope for is a few cleanish windows, mostly from light offshore or cross-off breezes, but the swell is just too tiny to get excited about.
Saturday morning 15th August offers a faint glimmer – clear skies and a light N wind at 9 mph keeping things clean, but it's only 0.7 ft of WSW swell with a short period of 7 seconds and weak energy (11). It's a total non-starter. From there, we sink into a week of moderate to fresh cross-onshore winds and choppy, lumpy conditions. Swell stays below 2 ft most days, with the odd pulse of longer period energy (17-19 seconds) on Sunday 16th and Monday 17th, but those come with 16-19 mph onshore wind, so no joy.
By Saturday morning 22nd August, we get a brief clean spell with N wind at 16 mph and 1 ft of SSW swell (period 15s, energy 80), but the waves are still tiny. Sunday morning 23rd August sees a proper offshore wind from the NE (16 mph), clean conditions, and 1.0 ft of SSW swell (period 14s) – it looks good but you'll be struggling to paddle onto anything.
The real standout, and I mean the only one worth mentioning, is Thursday morning 27th August. The wind goes light from the ENE at 6 mph, clean, and we finally see a bump in swell to 3 ft from the SE. The period is a short 5 seconds and the energy is still low (56), but at least it's something. Friday morning 28th August looks similar – 4 ft of SE swell at 6 seconds (energy 98) with light W wind, but the onshore cross will put a ripple on it. For the whole 16 days, that's about as good as it gets: small, short period, but clean.
Honestly, for the first week, save your energy. The second week has those couple of mornings that *might* be worth a quick paddle if you're desperate, but don't expect any magic. Long Strand–Castlefreke is fairly consistent, so this blank run is more of a slow patch than a dead zone – forecasts can turn.
Stay tuned, and keep the wax handy.
Rusty.
