The Lowdown

Alright, Rusty here. Let's have a look at what's cookin' for Aberystwyth harbour trap over the next couple of weeks. Honestly, I gotta be straight with ya – it's a tough stretch ahead. There's nothing in the entire 16-day window that gets a thumbs up for a proper surf. The water temp is sittin' at 64° which is much warmer than what we'd normally see for this time of year, so that's a weird one.

We kick off Sunday the 13th with tiny, weak swell – 2ft from the WSW with a short period of 7 seconds and a combined energy of only 26 (weak). The wind's cross-on and we've got light rain, so it's just poor conditions all round. That sets the tone.

Monday the 14th stays small and messy, cross-onshore winds again, period droppin' to 4 seconds. Nothing doin'. Tuesday the 15th brings a bit more size – 3ft from the W – but the period's still short and the wind's onshore at 19 mph. The energy bumps to 76 (still weak), but it's rainin' and the quality is shot.

Wednesday the 16th and Thursday the 17th see onshore winds and swell around 4ft to 4ft with 6-second periods. Energy climbs to 109 on Wednesday morning (moderate), but it's still onshore and sloppy. Friday the 18th hits a peak of 6ft from WSW with 6 seconds, and energy jumps to 242 (moderate). But the wind is a strong cross-shore at 25 mph, makin' it a lumpy, cross-choppy mess – more of a kite-surf setup than paddle surf.

The weekend of the 19th and 20th stays poor – fresh cross-onshore winds and lumpy conditions, though Sunday morning the 20th does go clean for a moment with cross-offshore wind, but the swell's only 2ft. That's a tease, not a session.

From Monday the 21st through to the end of the period, it's mostly tiny or flat. The 22nd has a spike to 4ft from NNW with 6 seconds and 126 energy (moderate), but it's cross-on and choppy again. A few mornings around the 24th and 25th go glassy or offshore – like Thursday the 24th morning with glassy conditions and a light ENE breeze, or Friday the 25th with offshore ESE wind – but the swell's basically zero to 2ft with periods of 4 seconds or less. Clean but flat.

So, bottom line: there's no standout session here. Not one day scores higher than a zero out of ten. The harbour trap needs a proper SW groundswell with light offshore winds to fire, and we just ain't gettin' it this fortnight. The only positive is that when it's this consistently poor, it usually doesn't stay that way forever – forecasts can change. But for now, keep your board in the van and maybe take a walk along the prom.

Rusty.

A general guide to surfing at Aberystwyth harbour trap can be found by selecting the local surf guide option on the grey menu.

Very soon you may start to choose your surf days based on the wave energy alone combined with our forecast of favourable offshore wind conditions.

Further information to help with frequently asked questions about our surf forecast for Aberystwyth harbour trap may be found under the help tab on the top menu and also by moving your mouse over the question marks on the surf forecast table itself.
