The Lowdown
Alright, crew, Rusty here. Let’s break down what’s coming.
It’s a bleak outlook, to be honest. We’re looking at a solid 11-day stretch with nothing worth paddling out for. The only potential window I can see is right at the tail end, on Monday the 31st of August.
The only break with a whisper of hope is Tullan Strand. On that Monday morning (31st August), there’s a tiny bit of swell – 0.6m from the W, with a period of 11 seconds. The wind should be a light SSE cross-off, so it’ll be clean. The wave energy is only 90 (weak), so it’s going to be really small and lack punch. The water is sitting at 62°, a touch warmer than average.
The rest of it is a write-off. From the 16th to the 30th of August, it’s all marked as poor surf conditions. On the 19th of August, we get a 3.0m swell, but it’s hammered by 25 mph winds, creating a strong cross-shore chop (combined energy 1796). That’s not one for a paddle board; that’s kite-surfing weather.
Basically, don’t get your hopes up. The 31st is a maybe, but it’s a gamble. It’s a long spell of flat and ugly. As always, things can change, but for now, it’s a real bummer.
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.
