The Lowdown
Alright, Rusty here, and I’ve been staring at the charts for Tam O'Shanter. Honestly, mate, it’s a tough run ahead. This spot is a point break that rarely breaks, and over this whole 16-day window, it’s just not ticking. We’ve got a long stretch of flat to tiny, messy surf, and it’s going to be a real struggle to find anything worth paddling out for.
We kick off on Tuesday the 25th with a tiny 0.3ft NW swell with a super long 17-second period, but it’s barely a ripple with weak combined energy (21). The wind is a cross-offshore, but there’s nothing to ride. This flat, poor pattern hangs on for days. Through the rest of August and into early September, the swell stays almost non-existent, mostly under 2ft. There’s a slight bump on the morning of Friday the 28th of August, where a 3ft WNW swell shows up with moderate energy (125) and clean, offshore SSW wind. But it’s still tiny and the wave comment says “surfable but very ordinary,” so it’s a one-star day at best. The afternoon gets chopped up again.
The next little flicker comes on the afternoon of Tuesday the 1st of September, with a 5ft NW swell pumping combined energy to 172, but the period is a weak 6 seconds and the wind is a strong cross-shore. With those conditions and a beach-and-reef setup, this is looking more interesting for kite surfing than paddle surfing, to be honest.
Later on, the morning of Wednesday the 9th of September brings the biggest swell of the period: a 6ft WNW swell with very strong combined energy (306) and a fresh cross-offshore wind. The wave quality is still rated poor, but if you’re an expert, this is the closest thing to a standout. It’s the only day with over 5ft of swell, which means it’s too big for beginners, and with the long period (15+ seconds) at a point break, it could offer some proper lines if it actually breaks. But that’s over a week away, so don’t book your trip on it.
Water temp is around 56°F, which is about average for the time of year.
Basically, there’s no real gold in this forecast. A blank run like this is more normal for a spot that rarely breaks. Hang tight and check back.

Information about the Tam O'Shanter Surf forecast
The above surf forecast table for Tam O'Shanter provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Tam O'Shanter can be found by selecting the local surf guide option on the grey menu. Our Tam O'Shanter 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 (Tam O'Shanter) 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 Tam O'Shanter 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.
