The Lowdown
Alright folks, Rusty here with the long-range look at what’s coming our way at Tullan Strand.
We’ve got a real mixed bag ahead. The next few days are pretty much a write-off for any real session, with dirty onshore wind and messy waves. There’s a bit of a lull until we see some proper potential. The standout window looks like Sunday, September 20th, with another promising spell around Thursday, September 24th. Be prepared for some crowd likely on the good days out there.
Right now, Monday the 14th is offering ankle to knee high waves at 2 to 3 ft from the west, but the wind is a cross-off and the conditions are just ordinary. The water is sitting at a touch warmer than normal for the time of year, which is a nice thought, but the surf is not. Tuesday and Wednesday the 15th and 16th get blown out by strong westerly winds, with the swell jumping up but getting hammered. We see moderate wave energy on Monday afternoon (195) climbing to strong energy (494-659) later, but it’s all rubbish. Thursday the 17th looks heavy and dangerous, with a massive 12 ft west-northwest groundswell and very strong energy (4,404), but with fresh cross-onshore winds, that is strictly for kite surfers or folks who like a beating, not a paddle session.
We hit our first moment of hope on Friday, September 18th. The morning sees a solid 8 ft west-northwest groundswell with a long 13-second period, and the wind swings to a light cross-off. That’s a serious amount of energy (1,997) hitting the beach, but it’s a heavy wave. It’s on the big side for beginners, better for someone with experience. The tide might be an issue, but the offshore wind will have it clean. Saturday the 19th looks messy again.
Now, Sunday, September 20th is the first standout. Sunday morning brings a beautiful window. We’ve got a 7 ft west-northwest groundswell running on a long 14-second period, combined with clean, light offshore wind from the southeast. The energy is strong (1,519), and conditions are described as excellent for experienced surfers. This is the one to circle. The afternoon gets a bit mushy with a cross-shore wind, so make the most of the early session. Crowds are listed as “sometimes” here, but for a clean 6 ft day with that period, get there early to beat the local crew.
The following week is more manageable but still has moments. Monday the 21st to Wednesday the 23rd of September has inconsistent, smaller swell in the 3 to 5 ft range with cross-off winds, but nothing that will blow your mind.
Then, Thursday, September 24th is another real highlight. The morning is small with a 2 ft wave, but then Thursday afternoon drops a bomb. A clean 6 ft wave from the west shows up, with a *very* long 15-second period. The wind is a light cross-off from the south-southeast, making for clean, lined-up waves. The energy jumps to strong (1,246) and it’s rated excellent for experienced surfers again. This is groundswell gold. Because of that long period, Tullan’s beach setup might have it breaking a bit straight, but with the right tide, the points should fire. If you can only pick one day, this afternoon session looks like the pick of the pack.
After that, Friday the 25th and Saturday the 26th of September fade into smaller, glassy conditions but the size drops off. By Monday, September 28th, we start to see another solid pulse of 8 ft west swell (1,870) with clean cross-off wind, but that is over a week away, so we’ll keep an eye on it.
In short: bag the first few days, be ready for a big, clean swell on Sunday, September 20th, and absolutely pencil in that stunning Thursday, September 24th afternoon for the real gold.
Rusty.

Information about the Tullan Strand Surf forecast
The above surf forecast table for Tullan Strand provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Tullan Strand can be found by selecting the local surf guide option on the grey menu. Our Tullan Strand surf forecast is unique since it includes wave energy (power) that defines the real feel of the surf rather than just the height or the period. If you surf the same spot (Tullan Strand) regularly then make a mental note of the wave energy from the surf forecast table each time you go. 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. 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. Please always bear in mind that the forecast is for near-shore open water and local factors at each surf break influence the actual breaking wave height, such as the beach / reef profile, water depths offshore and shelter.
