The Lowdown
Alright, let’s run it back in feet and miles for the old-school crew.
Right off the bat, we’ve got a long dry spell. There’s just nothing worth paddling out for from Monday the 31st of August all the way through the first week of September. The wind is howling, the swell is a mess, and even when we get some size—like a solid 8ft (Thursday 3rd) and a whopping 10ft (Thursday afternoon and again Saturday 5th)—the wind is a brutal 28 to 31 mph from the west. That’s clean, sure, but it’s a full-on gale. The wave energy is huge (759 on Thursday morning, 1447 that afternoon, and 1760 on Saturday afternoon), but this is a point break that rarely breaks anyway, and with that much wind, it’s a wild, blown-out mess. The water’s sitting at 56°, which is pretty standard for the time of year, nothing to write home about.
We finally get a tiny window of hope on Wednesday the 9th of September. The morning session shows a glassy, clean surface with a light offshore wind from the SW at just 3 mph. The swell is tiny, though—only 1ft from the NW with a very long period of 18 seconds. The combined energy is weak (112), but it’s a groundswell that’s going to wrap in nicely on a point break like this. You’ll be waiting for sets, but the waves that come will be clean and lined up. It’s only for the die-hards who know the bank and don’t mind the inconsistency. The crowd factor is "sometimes," so you might have a few others out there, but it won’t be a circus.
After that, it’s back to the doldrums. The rest of the second week fades out with tiny, weak swells and poor conditions. The morning of Tuesday the 15th of September is glassy, but the swell is just 0.3ft. It’s a flat spell.
So, the only real standout in this whole 16-day window is that Wednesday morning (9th September) at Tam O'Shanter. It’s a clean, quiet, long-period groundswell with offshore wind. Everything else is a write-off. If you’re patient and you love the place, that’s your moment.

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.
