The Lowdown
Howdy, Rusty here. We’re looking at a rough start at Tullan Strand – no real surf worth paddling out for until nearly the end of the month. You’ve got a solid six-day gap of weak, onshore junk. Water’s about normal for the season, nothing out of the ordinary.
The only time it gets interesting kicks off Saturday, August 29th . The afternoon is the real standout: an 8ft swell from the WNW, clean with a moderate offshore wind from the SE. That’s got some grunt – combined energy is 885 – and it’s going to be proper. Anything over 8ft is for experts only, so respect that. The morning of the same day sees a bigger 12ft WNW swell with cleaner conditions and an offshore wind, but that’s even more serious at 1583 energy.
Sunday the 30th of August morning is a solid option too – 6ft WNW groundswell with a light offshore breeze, glassy conditions, and combined energy of 518. Much more user-friendly. Monday the 31st of August morning drops to a clean 4ft W swell with a moderate offshore wind, good for a fun session. This spot faces west and loves swell from the west, so those directions line up.
Into early September, we get some size again – 8ft and 8ft W swells – but the wind turns cross-shore or onshore, stirring up chop. Not worth it.
So your call is Saturday the 29th through Monday the 31st of August. Saturday afternoon is the best of the bunch. Don’t waste your time before that.
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.
