The Lowdown
Alright, Rusty here. Let’s break down what we’ve got at Tullan Strand for the next couple of weeks.
Honestly, the next 11 days are a write-off if you're looking to catch a proper wave. It’s a grim stretch of flatness and weak energy. You’re better off keeping the board in the truck and just watching the tide come in for a week and a half. From now, all through the weekend of the 16th and into the following week, we’re looking at a dribble of short-period, weak swell. The combined wave energy numbers are pathetic, usually under 100. It's a dead spell. You get the odd clean moment, like on Monday morning with 0.7m of WNW swell and glassy wind, but "poor surf conditions" is the phrase of the day – there’s just no power. Tuesday the 11th looks clean with a light offshore wind, but the swell drops to 0.3m with a period of 7 seconds. It’s barely a wrinkle.
The poor run continues. On Thursday, August 20th, the swell size finally bumps – we’re looking at 1.8m – but it’s a messy, short-period wind swell hitting during a cross-onshore. The combined energy jumps to over 350, so there is power, but the wind wrecks it. It’ll be a choppy mess. That setup is more interesting for a kite surfer than for us with paddles.
The one stand-out window lands on Friday, August 21st. After 11 days of frustration, the stars finally line up for a single morning. We’ve got a clean 1.1m WNW swell, period around 10 seconds, with moderate energy (250). It’s not massive, but the gift is the wind: it's dead calm, glassy. For a break exposed to the northwest like Tullan Strand, that’s perfection. The water temp is about 61°F, running a touch warmer than normal for August. Since the spot is consistent, you’ll see sets coming through regularly. It’s small enough for beginners to handle, but clean enough for everyone to get a fun one. Crowds can be a thing here on a good day, and with glassy conditions like that, expect company.
But it's a short window. By the afternoon of the 21st, the wind swings onshore and messes it up, and the following weekend turns flat again with weak, choppy junk.
So, don't get amped for this whole forecast. Save your energy and your wax for that glassy Friday morning. It’s the only real highlight.
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.
