The Lowdown
Alright, Rusty here. Let’s break down Tullan Strand over the next couple weeks.
The one to mark on the calendar, the true standout, is the morning of Sunday the 13th of September. Waves are about 4 feet from the WNW with a period of 11 seconds – that’s proper groundswell with some grunt. The wind is glassy out of the SSE, so it’s going to be clean as a mirror. The combined wave energy is moderate, sitting at 279. For a consistent, beginner-friendly spot like Tullan Strand, that early session is the best you’re going to get. Water temp is about normal for the season.
That Sunday afternoon, the swell drops a bit to about 3 feet, and the wind goes to a light cross-off from the south. It stays clean but the energy falls off to 186. Still surfable, just average.
Come Monday the 14th, the swell crashes to nearly nothing – 1 feet in the morning with a weak 8-second period and only 57 energy. The wind is cross-off but there’s just no push. That afternoon bumps to 3 feet and a longer 11-second period, but the wind picks up to about 12 mph from the south with rain. Not worth it.
From Tuesday the 15th through Thursday the 17th, it gets ugly. Onshore and cross-onshore winds pick up to 25-30 mph, with rain and choppy, lumpy conditions. Swell sizes get big – up to 10 feet by Thursday afternoon with a massive 4026 combined energy – but it’s all wind-beaten junk. That 10-foot, 16-second period groundswell with strong winds is strictly for kites, not paddles.
Friday the 18th morning looks better: about 8 feet from the west at 13 seconds, 2288 energy, and a cross-off breeze from the southwest at 15 mph. It cleans up, but that size is expert-only for most.
The weekend brings a mixed bag. Saturday the 19th is blown out with 28 mph cross-onshore winds and 12 feet of mess. Sunday the 20th morning is promising: 10 feet from the WNW, 14-second period, cross-off wind from the south at 15 mph, and 3380 energy. Clean and powerful, but only for the brave.
Then we get another windy stretch through Monday the 21st and Tuesday the 22nd, with onshore winds and lumpy surf despite solid swell.
The best of the second week might be Thursday the 24th morning: 12 feet from the WNW, 13-second period, 3829 energy, with a cross-off breeze from the south at about 12 mph. That’s big and clean. The afternoon goes even bigger to 13 feet and 14 seconds, but the wind picks up a notch. Keep an eye on these – the conditions might line up.
From the 25th onward, it fades. Winds go onshore again, and by Monday the 28th morning, we’re down to 2 feet of weak, glassy dribble with only 92 energy.
Bottom line: the standout is this Sunday morning, the 13th. The second week has potential on the 20th and 24th, but those are for experienced heads in big swell.
Rusty, out.
