The Lowdown
G’day, Rusty here, and I’ve gotta be straight with you – this outlook for the next couple of weeks is a tough one. We’re looking at a long, flat spell, so don’t be in a rush to grab your board. The first half of the period is a write-off, and the second offers only a whisper of hope.
### Tullan Strand
Alright, so we kick off on Saturday, the 15th of August, and there’s nothing doing. It’s a cross-onshore breeze, and the swell is tiny. The water temperature here is 62.8°, which is much warmer than normal for this time of year, but that’s the only good news. The combined swell energy is a weak 83, and that’s about as good as it gets for a while.
We go through Sunday, the 16th, and Monday, the 17th, with mostly clean winds but the swell is pathetically small – 1.6 ft to 2.6 ft from the west-northwest, with periods around 8 seconds. The energy stays weak, barely cracking 86. Then things actually get worse. From Tuesday the 18th through Thursday the 20th, the swell picks up a bit to 3.9 ft, 4.3 ft, even 5.2 ft from the west, and the energy climbs to moderate levels (164 to 476). But here’s the kicker – the wind is howling. It’s a fresh cross-onshore, blowing 15-18 mph, and the surf is described as "poor surf conditions" across the board. It’ll be lumpy, choppy, and just plain ugly. Not worth paddling out for.
After the 21st of August, it’s back to nothing. We get a long gap of deadness. From the 21st right through to the 29th, the swell drops to a pathetic 0.3 ft to 1.3 ft, with combined energy in the single digits or low teens. The wind sometimes goes light, even glassy – like on the morning of the 27th of August with a glassy surface and a 0.7 ft west-southwest swell at 11 seconds – but there’s no push. It’s just a flat, clean lake. You’d be better off swimming.
The only slight flicker comes right at the end of the period. On Sunday, the 30th of August, the swell pushes back up to 3.3 ft from the west-northwest, with an 8-second period. The energy hits 101 (moderate), and the wind is a light cross-onshore at 6 mph in the afternoon. The break is consistent, and the optimum swell direction is from the west, which matches the direction of this swell. Still, we’re only looking at 3.0 ft to 3.3 ft, and it’s not a standout by any means. If you’re desperate, it’s the best of what’s on offer, but it’s not a day to get excited about. Given the light wind, it might clean up a touch, but the quality is still a question mark.
So, overall, this is a bleak run for Tullan Strand. With mostly inconsistent swell and poor surf quality, I’d say it’s not looking good for the paddle. If you’re a kite surfer, the stronger winds mid-period might be more interesting for you, but for a surfer, there’s nothing to chase.

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.
