The Lowdown
Right. Let me be straight with you. I’m looking at the whole 16-day window for Tam O’Shanter, and to be honest, it’s a tough stretch. This is a point break that rarely breaks, and for nearly two weeks, it’s just not lining up. There are no standout days, no real sessions to get excited about. You’re looking at a long gap of poor-to-marginal conditions from Wednesday 20 August through to Thursday 28 August, where we finally see a slight flicker of hope. Even then, it’s nothing to write home about.
The only period worth mentioning at all is the tail end of the first week and the start of the second. On Thursday 27 August morning, we get a brief moment of glassy conditions with a 4ft NW swell, but the energy is weak (88) and wind is light. That’s the closest to surfable you’ll see, but it’s just ordinary. Then on Friday 28 August morning, the swell picks up to 5ft from the WNW, with a clean cross-offshore breeze and moderate energy (266). That’s the best of the lot – but “best” here means it’s just surfable, not good. The direction is close to optimum (NW), but the break is inconsistent and rarely lines up like this. With a period of 7 seconds, it’s a short-period wind swell, so expect a bit of chop on the face. Water temp is around average for this time of year, nothing unusual.
After that, it drops right off again into tiny, weak dribble through to the end of the period. Honestly, if you’re desperate, that Friday morning is your window – but if it were me, I’d wait for a better run. The setup here is a point, but with such weak energy and rare consistency, it’s tough to get excited.

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.
