The Lowdown
Alright, Rusty here, and I've got the scoop on what's cookin' at Tullan Strand. It's a bit of a mixed bag for the next couple of weeks, so let's get into it.
First off, the water is sitting at a balmy 63°F which is *much warmer than normal* for this time of year—a real treat if you're not wearing a steamer.
Right now, it's pretty grim. We've got a messy cross-onshore wind and a weak, choppy 3ft NW windswell. The energy is pathetic (88), and frankly, you're better off waxing your board indoors. That same blown-out, small junk continues all through Friday, Saturday, and into Sunday morning. Sunday morning gets glassy but the swell is only 0.7ft—flat.
Alright, here's the first real glimmer of hope. On Monday, August 24th, the wind goes clean with a light offshore breeze from the SE. Swell jumps to a clean 3 to 4ft from the WNW with a longer 10 to 11-second period. The energy is solidly moderate (265), so the waves will have some real push. This is a good one for your shortboard or fish.
We grind through a few more small, clean days but nothing worth rushing for until Thursday, August 27th. That morning, we see a proper pulse of swell: 7ft from the WNW! The energy is strong (574), so it's got some punch. The wind is clean from the ESE, making for some very good conditions. This is your standout forecast. Just a heads up: at 7ft, this is pushing into the "too big for beginners" zone. It's going to be a rippin' day for the experienced crew.
That swell fades quickly into Friday with onshore winds ruining the party, and we drift back into tiny, choppy dribble for the weekend.
But don't write off the second week yet! On Monday, August 31st, another solid groundswell fills in. We're looking at a clean 6ft wave from the W with a 9-second period. The energy is very strong (561) again. The wind is a light cross-offshore from the SSW, which should keep it all clean. This one is another legit option for intermediate to advanced surfers. After that, it's back to the onshore winds and small, windy junk for the rest of the forecast window.
So the bottom line: keep your eyes on Monday the 24th for a fun, manageable session, and Thursday the 27th is the real standout for the bigger-wave crew. The 31st is worth noting too, but it's a longer way out.
Rusty, signing off.

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.
