The Lowdown
Alright, Rusty here. Let’s talk about what’s cooking at Swamis.
It’s a bit of a slow start. We’ve got some small swell rolling in, but the quality is just not there for a proper wave. Friday the 21st and Saturday the 22nd are looking weak with little 2ft to 3ft swell and a combined energy that just doesn’t have the punch (208 to 324). The wind is blowing onshore, so it’s messy. You’d be better off staying on the beach.
Things stay pretty flat and uninspiring right through the following week. The swell stays small, mostly under 3ft, and the wind is cross-onshore or onshore, keeping the surf poor. There’s a bit of a bump in combined energy from the 25th to the 27th, getting up to 1064, but it’s still cross-onshore and the wave quality is marginal at best. Not worth a paddle.
The real standout is way down the line, on Friday the 4th of September. This is the one to circle on the calendar. Early morning, we’ve got glassy conditions with the lightest breeze, and the swell is a clean 3ft from the southwest at 17 seconds. That’s a proper long-period groundswell. Combined energy is a solid 521, and with the wind glassy, it’s going to be clean. The water temp is about average for the time of year. This is your best chance for a decent session.
The following day, Saturday the 5th of September, the swell jumps up to 7ft from the south with a 14-second period and combined energy of 1791. That’s a lot of power. But the wind is cross-onshore, so it’ll be a bit lumpy. This one is for the experienced crew only – it’s going to be a handful.
Overall, the first week and a half is a bit of a write-off. The best bet by far is that Friday morning on the 4th of September. Get out there if you can.
Rusty.

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