The Lowdown
Right folks, Rusty here. Let’s take a good, hard look at what Swamis is doing over the next couple of weeks.
Straight up, it’s a pretty quiet period for this spot. For the first week or so, the waves are mostly small and the wind is a constant pain in the arse, making things choppy and ugly. The water is sitting at 72.3°, which is 4° warmer than usual for this time of year – that’s pretty notable, like the ocean had a hot flash. The overall energy in the water is moderate on the first day, with the combined swell energy at 548, but it’s messy.
The first real window to get slightly excited about is Thursday the 11th, in the morning. We’ve got a 3.3ft swell rolling in from the SW, with a long period of 16 seconds. That’s proper groundswell, which will wrap in nicely, but the wind is cross-shore at 9 mph, so expect some cross-chop. It’s still just a marginal call though. The combined energy here is 531.
Honestly, there’s no true standout in this whole 16-day window. Everything is scoring as either poor or marginal. The wind is almost always on it from the SW or WSW, keeping the surface messy. Even when the swell tries to show up in the second week, like around the 20th of September, you’re looking at 2.9ft to 3.6ft from the SW with a 17-second period, but the trade winds are just going to ruin it. The combined energy on the 21st of September afternoon hits 691, which is the highest in the whole run, but the onshore wind kills it.
If you are desperate, the morning of Sunday the 20th of September is the least of all evils. A clean 2.9ft from the SW, 17-second period, with light offshore wind from the WSW at 6 mph. The conditions will be glassy, and that long-period swell will hold up well on the reef. The combined energy is 578. It’s not going to be firing, but for a paddle and a few cruisey ones, with the water feeling warm and no crowds likely, it’s your best bet in a pretty flat run.
The rest of the second week is more of the same – small, wind-affected, and marginal. It’s a lean spell, boys. You gotta be patient.

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.
