The Lowdown
Alright, Rusty here, taking a look at the local surf scene for the next couple of weeks.
Right off the bat, we’ve got a bit of a flat spell to get through. The first real chance of a paddle comes on Tuesday, August 25th, with a clean little 3ft swell from the west at Tullan Strand. The wind is light and offshore from the SSE, so the surface will be looking tidy. It’s not big, but it’s a start. The water is sitting at 63°, which is much warmer than usual for this time of year, so you might get away with a thinner suit.
The real standout, the one you’ve been waiting for, is looking at Friday, August 28th. The morning session at Tullan Strand is the pick of the entire forecast. We’re looking at a solid 7ft west swell with a clean 10-second period. The wind is light and offshore from the SSW, so it’s going to be glassy. The energy is pumping hard at 955 (moderate wave energy), and the conditions are set to be very good. This is a proper session for the experienced crew; the swell is getting up there, so it’s not one for learners.
After that, the swell builds even bigger, but the wind turns ugly. By the 31st of August, we’re looking at a massive 15ft groundswell from the west with a very long 14-second period. The energy is enormous at 7020 (very strong wave energy), and the wind is light and offshore, so the surface is clean. However, this is simply too big for Tullan Strand. It’s an expert-only situation if you’re crazy enough, but honestly, the setup looks more interesting for a kite session than a paddle. The same goes for the start of September, with a 10ft swell on the 1st, but it’s a bit of a mess.
So, if you’re looking for a window, hold out for the morning of the 28th of August. That’s the one. The long-range stuff on the 31st is promising but way too big for this spot.
Rusty, signing off.

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.

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.
