The Lowdown
Alright, I’m gonna give it to you straight about Tullan Strand over the next couple weeks. Most of it is a bust, with maybe one or two tiny bright spots way down the line.
Right off the bat, from Monday July 20th through Friday July 24th, there’s barely a ripple. We’ve got tiny little 0.3ft to 0.7ft slop, short period, onshore junk blowing all over it, and hardly any energy (combined energy numbers less than 100 for that stretch). That’s weak, real weak.
Water temp on Monday morning is weirdly warm – 65°F, which is 7°F warmer than normal for this time of year. That’s very unusual, makes the Atlantic feel like a heated pool. Doesn’t help the waves though.
Then from Friday the 24th into the weekend we see a bump – swell heights climb to around 4ft to 6ft from the west-northwest with periods around 8-10 seconds, and the juice gets up there with combined energy values over 600 on Saturday morning. Sounds decent, right? Wrong. The wind stays cross-onshore, choppy, lumpy. The comments say “poor surf conditions” or “marginal” at best. So you get bigger, messier lumps – not really what you want.
The only moment that catches my eye is way out on Thursday July 31st morning. Over a week and a half away, so don’t hold me to it, but the forecast shows a tiny 2ft W swell with an 8 second period… and for once the wind swings offshore from the southeast. Clean conditions. It won’t be pumping, but if you want a glassy, quiet longboard session with no crowd hassle – that’s your window. Crowds are “sometimes” here, so with those conditions you could have the place to yourself.
But take a step back – this 16-day outlook is a tough one. There’s a big dry spell from now until that July 31st morning where I just can’t say it’s worth the paddle. A bit more energy shows up around August 3rd-4th, but the winds are fresh and messy again.
Just the nature of this spot sometimes. Keep an eye on it – forecasts can turn – but for now, stay patient.

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.
