The Lowdown
Right then, let’s take a look at what’s on the cards for Tullan Strand over the next couple of weeks.
To be brutally honest, for most of this period, it’s pretty grim. We’ve got a long, drawn-out stretch of small, junky surf with onshore winds that just won’t quit. The combined swell energy is mostly weak, sitting under 100 (41 to 15), and the wave heights barely tickle 2ft to 1.0ft for the first ten days. It’s the kind of run that makes you question why you packed your board. There’s a brief little moment on Tuesday the 21st morning, with glassy conditions and a 1ft swell from the W, but that period of 10 seconds is a long one for such a tiny wave – it might offer a few clean, though slow, lines for a log. But that’s it. We’re looking at a solid gap of almost no worthwhile surf until the very end of the month.
The first real flicker of life comes right at the end of the month. On Friday the 31st of July, the whole picture changes. We get a jump in the combined swell energy up to a moderate 470, with the swell picking up to a clean 5ft to 6ft out of the west. The wind swings around to a lovely offshore and cross-off from the ESE and SE. That’s going to clean things right up, putting some proper shape in the water. This is easily the best on offer. Saturday the 1st of August still has some clean, smaller waves at 3ft from the west in the morning with a light S breeze, but the energy drops back.
So, for a stand-out, you are waiting for that Friday the 31st of July morning and afternoon. Tullan Strand is a consistent, exposed beach, and when it gets a clean 5ft to 6ft of westerly groundswell with that offshore wind, it should have some proper, punchy banks. It’s going to be very clean. That’s your window.
This is Rusty, signing off.

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.
