The Lowdown
Alright folks, Rusty here. Let's get into this one.
It’s gonna be a rough couple of weeks for Tam O'Shanter. This point break is a fickle one that rarely breaks, and over this 16-day window, there isn't a single moment where I'd tell you to paddle out. Most of the time it's either flat or ankle-high, and when there is a little bump, the wind usually has its say.
For the first week, up through the 23rd of August, we are looking at mostly tiny 0.3ft to 2ft slop, constantly blown out by cross-onshore breezes. The swell periods are too short to build any sort of shape. It's a washout.
We see a pulse on the 20th of August with mixed swells pushing in around 6ft from the NW, and the combined energy is 310 (moderate), but a 30 km/h cross-shore wind from the WNW will tear it apart. It’ll be lumpy and choppy, more of a kiteboarding scene than a surfing one.
Now, there is something on the 22nd of August. Saturday morning looks clean with a 5ft swell from the WNW and a cross-offshore wind from the West at 30 km/h. The total energy is 230 (moderate). That’s a tempting window, but 5ft is a fair size for this spot, and since it rarely breaks, you’d be gambling on it. The following day, the 23rd, shows a 6ft from the WNW (energy 311, moderate), but the cross-shore wind comes back, making it choppy again. At 6ft, you're looking at an experts-only zone in messy conditions.
Later on, the 30th of August shows 6ft from the NW (energy 321, moderate), but with onshore winds and rain, it's a hard pass.
Honestly, there's not a single standout session here. The spot is inconsistent, so this kind of flat spell is just part of the deal. Keep watching, because it never stays this way for long.

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.
