The Lowdown
Alright, Rusty here. Let's have a look at what's coming down the line for Tullan Strand. There's a bit of a mixed bag over the next couple of weeks, but we’ve got a serious standout window to mark on the calendar.
The water is sitting at 61°, which is a touch warmer than normal for this time of year—not a major shift, but pleasant enough.
The week starts off pretty average. On Friday morning, the 11th, we're looking at a weak 4ft W swell but it’s a short-period 8 seconds and the wind is a messy cross-on from the WSW. Not worth rushing out for. By Friday afternoon, it cleans up nicely with a cross-off breeze and a 4ft WNW swell stretching out to 9 seconds. The wave energy is still low (276), but it’s surfable.
Saturday the 12th sees a big jump in size, with a 7ft W swell and a better 11-second period. The combined energy is strong, reading 1126, but the wind is a cross-shore from the WSW at 15 mph, churning up a cross-chop. That 7ft is getting into the territory where it might be too big for beginners, and the quality is marginal. Saturday afternoon drops to 6ft but stays messy.
Now, Sunday the 13th morning is the first real highlight of this early stretch. Glassy conditions, a light S breeze, and a clean 4ft WNW swell with an 11-second period. That's a very long period for the size, meaning it'll have some punch and shape but the sets will be spaced out. It’s a real clean-up session for someone who wants an easy paddle. The energy is low at 279, but the quality is there.
After that, things take a turn. From Monday the 14th through to Wednesday the 18th, the wind is a problem. We’ve got fresh cross-onshore and onshore winds for most of that time, with a couple of big days on the 17th where the swell hits 8ft from the WNW with a 12-second period and a massive energy reading of 1671—but the wind is a solid 22 mph cross-on. That’s going to be a lumpy, blown-out mess. Honestly, that setup looks way more interesting for kite surfing than paddle surfing.
We then hit a quiet patch from the 14th until the morning of the 19th, with only small, poor surf. Then, a glimmer. Saturday the 21st of September morning brings a clean 6ft WNW swell with a solid 12-second period, light offshore breeze from the ENE. That’s a solid combo. The energy is moderate-high at 861. This is promising.
But the true standout is the 22nd and 23rd of September. We’re looking at some excellent conditions for experienced surfers. Tuesday the 22nd morning kicks off with a 8ft W swell, 13-second period, and an offshore wind from the ESE at only 6 mph. The combined energy is a huge 2400. That’s a powerful, long-period groundswell. That size is for experts only. The break is exposed to the W, and the optimum swell direction is W, so this is right on the money. Beach breaks can get straight with such long periods, but at Tullan Strand, the shape should hold. Afternoon stays at 8ft with glassy conditions from a slight air.
Wednesday the 23rd is the same calibre: 7ft to 7ft, long 12-second periods, and by the afternoon it goes dead glassy with calm conditions and light rain. This is the absolute best window of the whole forecast. Get on it if you can handle it.
After that, from the 24th onwards, the onshore winds return and the quality drops off hard. Small, onshore slop with no real energy left.
So, for the best on offer: Tullan Strand on Monday 21st September morning is a great call for a solid, clean day. But for the true standout, Tuesday 22nd and Wednesday 23rd September are the real deal—big, long-period groundswell, clean offshore or glassy conditions, serious energy. Mark it. But be warned: this is expert territory with the size over 8ft.
Rusty.

Our star ratings will help here and of course you will also find the usual wave height and period predictions on our surf forecasts as well as a full break down of the swell components under our advanced users option (to reveal that, click the little Einstein character under the tide times).
Further information to help with frequently asked questions about our surf forecast for Tullan Strand 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.
