The Lowdown
Alright, Rusty here. Let’s have a look at the surf for the next couple of weeks.
The first week is mostly a write-off for decent waves, with poor conditions through to Sunday the 23rd thanks to moderate cross-onshore winds and choppy surf. There’s a 5.6ft west swell at Tullan Strand on the 19th but the wind is all wrong, making it a messy affair. You're better off waiting.
The first real chance of something clean comes on Monday morning the 24th. Tullan Strand will see a 3.9ft WNW swell at a solid 11-second period, giving the waves some push and shape. Combined swell energy is moderate (319). The real winner here is the glassy conditions: light southerly winds around 3 mph will keep the surface clean. It’s a consistent spot, and with crowds only sometimes an issue, you might actually find a bit of space. The water temperature is about average for this time of year. This is the standout window in the first week.
After that, Tuesday the 25th has a small 2.6ft west swell and gentle offshore wind, but the energy is low (138). It’s surfable but ordinary. The middle of the week slides back into flatness or poor wind, and there’s nothing worth chasing.
A real wildcard shows up on Sunday the 30th of August. Tullan Strand gets a chunky 7.5ft to 7.9ft west swell with a 12-second period, which is a long-period groundswell. The combined energy is very strong (1544 to 1665). However, the wind is onshore, which makes it a messy proposition for paddle surfing. This one is for experts only due to the size, and the onshore wind would make it more appealing for kites than surfboards. There’s nothing clean enough on the cards after that until Tuesday the 1st of September, when a small 3.9ft WNW swell and glassy conditions appear in the afternoon – a tiny but clean end to the run.
So, honest truth: Monday the 24th morning is your best bet. Get it while it’s clean.

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.
