The Lowdown
Alright, Rusty here again. Let’s talk about the water for the next couple of weeks.
Honestly, it’s a quiet stretch for Aberystwyth harbour trap (Wales). This reef break likes a southwest swell with an offshore wind from the ESE, but we’re looking at a long gap of days with nothing worth paddling out for. The whole 16-day window is pretty flat and messy.
The water temp is about what you’d expect for this time of year, nothing special.
The first bit of size shows up on Tuesday, September 8th, in the afternoon. Swell hits 6ft from the WSW with a period of 7 seconds, and combined energy of 319 (moderate). But the wind is cross-onshore from the WSW at 12 mph, so it’s choppy. Not clean, but it’s the biggest bump. Wednesday the 9th has 7ft from the WNW with a period of 7 seconds, energy 340 (moderate), but the wind is a fresh cross-shore from the SSW at 22 mph, making it lumpy. That’s too big and rough for beginners, really only for the hardcore expert.
Later on, Friday the 11th September morning turns glassy with a light SSE breeze at 3 mph, and the swell is 3ft from the SW (4 seconds), energy 28 (weak). It’s small and clean, but the period is short, so the waves will be weak and slow.
The best option in this whole run is probably the morning of Monday, September 14th. The wind is offshore from the ESE at 9 mph, so it’ll be clean, and the swell is only 0.7ft from the WSW (8 seconds), energy 6 (weak). It’s tiny, but if you’ve got a log and the tide’s right, you might find a few soft ones. Nothing to write home about.
This is a dead spell for the area. When a reef goes this quiet for this long, it’s just part of the deal. Forecasts can turn, but right now, I’d keep the board in the garage.
Rusty.
