The Lowdown
Alright, grab your board, 'cause I'm gonna give it to you straight. This outlook is for Trestrignel, and it's a bit of a grind for most of the next two weeks. We're looking at a long stretch of messy, onshore conditions and not a whole lot of clean, rideable surf. There's a real dry spell through the first week, so don't get your hopes up for any quick sessions.
The water's at 66°, which is a touch warmer than usual for this time of year. You might not need the thickest suit, but it's not exactly tropical either.
The first bit of the forecast, from the 16th through the 22nd, is pretty grim. The swell is weak and all over the place, mostly coming in from the WNW with periods under 9 seconds. The wind is almost constantly cross-onshore, which means it's going to be choppy and messy. The wave energy is weak, with values in the low to mid-hundreds at best, and often just double digits. It's the kind of surf that'll have you checking your phone for literally anything else to do. There's a small window on the 22nd morning, but it’s tiny, and the swell is junk. Honestly, for paddle surfing, this whole stretch is a write-off. If the wind picks up like it's forecast to, the bay might be more interesting for the kite surfers than anyone with a paddle.
Now, as we push into the 23rd and 24th, the swell picks up significantly, but it's a raw, powerful mess. It's coming from the NE and blowing into the beach, pushing waves over 8ft, hitting 10ft and even 13ft on the 24th afternoon. The wave energy jumps into four digits on the 24th, showing strong to very strong wave energy (1056, then 1924). But with a fresh breeze turning onshore and a short, 7-8 second period, this is going to be a brutal, closed-out beach break. This is expert-only sort of size, with terrible conditions. Not the time to be a hero. The wind is strong, and the surf quality is just poor.
Things start to drop out again after that. The 25th sees the swell back down, but the wind is still up, making it messy. From the 26th to the 27th, we're back to a tiny, weak swell. The morning of the 27th is interesting though—we get a light offshore wind from the S, and the afternoon goes glassy. The swell is only 1ft, but for a brief moment, it might be clean and tiny. This is a good chance for the beginners to get out in the whitewash.
The action, such as it is, doesn't really show up until the very end of the forecast period. On Friday, the 28th, the swell finally bumps up to around 5ft to 6ft with a longer 10-second period. The wind is light, too. The energy is moderate (523), but the conditions are still only marginal. The morning cross-shore wind is a bit of a put-off, but it's about the best we've seen in a week. Keep an eye on it.
The 29th has a morning with a light cross-offshore wind and 4ft of swell, which is clean, but it's not exactly firing. The good news is, there is a slight improvement in quality.
Looking further out to the 31st, we see a longer-period swell (11 seconds) coming in from the WNW, pushing energy up to the low 300s (313, 340). But the wind is a fresh onshore breeze, which means it's going to be lumpy. It's a tease, really.
So, what's the best on offer? Honestly, it's not much. The standout for the whole 16 days is probably Friday the 28th. It's got the biggest clean swell of the period, with a better period, and the wind isn't a complete mess. It’s not going to be epic, but it's the best of a bad bunch. The second pick would be the morning of the 29th, where you get a clean-ish 4ft wave, though it's not very powerful. Both are a far cry from perfect, but they're the only chances for a proper surf. The rest is a waiting game.
Remember, these long-range calls are promising but less certain. The near-term forecast is bleak, but for an area that is "fairly consistent," it tends not to stay this poor for long, and the signals for that last week do look better. We just gotta be patient.
Stay stoked,
Rusty
