The Lowdown
Swell’s pretty quiet for the next couple of weeks, but there’s a proper little window of clean surf that turns up late in the game. The only real standout is Tullan Strand, which is a consistent, exposed beginner-friendly beach break that works best with swell from the west. The water temp is 61°, which is a touch warmer than normal for this time of year, so it’s not a bad time to be in the water.
For the first week, it’s mostly flat to small. Tuesday 11th afternoon has only 0.7ft of swell with a long 13-second period, and the combined wave energy is a weak 21 – not worth paddling out for. Wednesday 12th and Thursday 13th stay tiny, with 1ft to 2ft, and the energy only nudges up to 100 on Thursday morning. The cross-off winds keep it clean, but the waves are just too small. Things stay poor through Friday 14th and Saturday 15th, with messy onshore winds and dropping energy. Sunday 16th afternoon sees a little light offshore wind from the southeast, but it’s only 1ft and 24 energy. Monday 17th morning goes glassy with 1ft, but still nothing to get excited about. Tuesday 18th morning has 3ft and clean cross-off winds, but it’s very ordinary.
The real highlight comes on Tuesday 25th and Wednesday 26th. Tuesday 25th morning serves up 7ft of west swell, offshore wind from the southeast, clean conditions, and a combined energy of 675 – that’s moderate to strong energy. The swell period is 9 seconds, which is decent. Tuesday afternoon pushes to 7ft with 850 energy and offshore southeasterly winds. That’s the best session of the whole outlook. It’s a solid size but still manageable for most surfers, and the wind is clean. Wednesday 26th morning stays big at 7ft but the wind swings northwest onshore, so it’s not as good. The afternoon bumps up to 8ft and 1021 energy, but again onshore, so it’s marginal.
Overall, the first week is a write-off for any proper waves. The gap between now and the 25th is long – nearly two weeks – so don’t get your hopes up until then. But that Tuesday 25th is a genuine standout. If you can wait, it’ll be worth it.

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.
