The Lowdown
Alright, folks, Rusty here. Let’s be straight with you about the surf ahead. We’ve got a long stretch of flat, weak, and messy conditions coming our way, and it’s going to test your patience. The first real chance of a wave doesn’t show up until the very end of the window, and even then, it’s a tricky one. The good news? The water is a touch warmer than usual, running at about 62°, which is a small mercy while we wait for something decent.
The next week and a half are a write-off for Tullan Strand. There's just no energy in the water. Through the 15th and into the 16th, we’re looking at tiny, poor surf with gentle onshore breezes making it messy. There’s a slight improvement on the morning of the 17th with a light offshore wind and clean conditions, but the swell is only 2ft with weak energy, so it’s not worth the paddle. We get a bit more push on the 18th when the swell jumps to 8ft, and the energy is strong, but that comes with a 25 mph cross-onshore wind that will have it completely chopped out and messy. Not the sort of day you want to be out there unless you’re after a fight.
From the 19th through to the 27th, it’s a real slog. Swell heights hover anywhere from 0.7ft to 5ft, but the period is mostly short (6-8 seconds), and the wind keeps swinging onshore or cross-onshore. There’s one morning on the 27th that catches the eye – a light offshore and a 2ft swell with a longer period (10s) from the WNW – but the energy is still weak, and the conditions are described as merely ordinary. It’s the only day in that whole stretch that even gets a score above zero.
Now, for the punchline. The last few days of the month have the real swell, but there are big caveats. On Friday the 28th, we see a very long-period (14s) groundswell from the west at a solid 13ft, and the energy is pumping – that’s very strong. But that size is only for experts, and the light cross-onshore wind will make it tricky. It’s also a long-period swell, and at a beach break like this, that can mean waves that stand up and close out. Saturday the 29th is still big – around 8ft – but again, it’s a powerful swell and a bit of a mixed bag with the wind. These last days are promising and have real potential, but they’re over a week out, so I’d treat them as a promising possibility rather than a certainty. It could be well overhead and grumbly, or it could be a bit of a washing machine. We need to keep an eye on it.
So, to sum it up: the next week and a half are a wash-out. The best bet is on the 27th for a splash and a hope, but the real excitement, if it lines up, is on the 28th and 29th for experts only. Patience, lads.
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.
