The Lowdown
Alright folks, Rusty here, and I’ve got the long-range picture for Tullan Strand. Gotta be straight with you – this is a tough read. It’s a bit of a waiting game with a lot of messy days before we see anything worth paddling out for.
The whole 16-day window starts with a real flat, choppy spell. From Tuesday, the 18th of August, right through to late August, we’ve got onshore winds and weak, short-period swell. The water temp is sitting at 63° F, which feels much warmer than normal for this time of year, but that’s small comfort when the waves are junk. The first solid swell pulse we see is around Tuesday, the 1st of September, with a building 7 ft groundswell from the WNW, but it’s completely blown out by strong NNW winds at 16 mph. That energy is moderate (392), but the conditions are hopeless for a clean ride.
The one standout, and really the only window worth circling on the calendar, is Thursday, the 27th of August. It’s not a classic, but it’s the best we’ve got. We’ve got a 3 ft swell from the WNW with a 9-second period, giving us moderate energy (144). The wind swings offshore from the ESE at 16 mph in the afternoon, and the notes say “clean.” For Tullan, that’s the pick of the entire forecast. It’s a small, clean day for a log or a fun fish. Crowds are “sometimes” an issue here, so with a decent forecast like this, you can expect a few others with the same idea. The swell direction (WNW) is right off the optimum (W), so it’ll break with a bit of push.
After that, we get a shot of bigger swell on the 1st and 2nd of September. Early on the 2nd, we’ve got 6 ft from the W with a 9-second period and clean offshore winds from the SSW. The combined energy is strong (562). This is a good, powerful wave, but at that size it’s pushing into the “experts only” territory, and it’s a long way out. Keep an eye on it, but don’t book the day off yet.
That’s it. A lean run, but that Thursday the 27th is the day to be in the water.

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.
