The Lowdown
Alright, this is a tough one to call. I’m looking at the whole 16-day window for Tam O'Shanter, and frankly, the surf is almost non-existent for most of it. We’ve got a long, quiet stretch ahead.
The first real pulse of any size comes in on Tuesday, July 14th, with a 5 ft swell from the WNW, but the period is a short 7 seconds. The wind is a strong 19 mph cross-off, which is clean, but the energy is weak (351) and the wave quality is just poor. That same pattern holds through Wednesday, July 15th, with similar 4 ft to 5 ft swell and strong winds. It’s not worth paddling out for.
Then we hit a massive dead zone. From Thursday, July 16th, all the way through to Sunday, July 20th, the swell drops to 0.7 ft or less. The energy is in the single digits and low twenties. It’s flat. There’s nothing to ride. The water temp is about 56°, which is normal for this time of year, but that doesn’t help the lack of waves.
After that, the last week of the forecast is a real mixed bag of tiny, weak swells and poor wind. The only slight glimmer I see is on Wednesday, July 29th, in the afternoon. We get a 4 ft swell from the NNW, with a 6-second period, and a light wind. The energy is weak (84), and the description says "surfable waves but very ordinary conditions." That’s about as good as it gets, and it’s still not good.
Honestly, this is a classic blank run for the area. Tam O'Shanter rarely breaks, and this forecast shows exactly why. There are no standout days, no one to get excited about. The only thing that looks interesting is the long period, tiny swells from the 17th and 18th, but they’re 0.7 ft or 1.0 ft at 15-17 seconds. That’s a groundswell, but with zero height, it’s just a ripple. For a point break, that long period would be perfect if there was any size, but there isn’t.
You’re better off waiting for the next system. Forecasts can change, but as it stands, don’t bother.

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.
