The Lowdown
Alright, Rusty here with the same read on Swamis, but in feet and miles. This spot is a mix of beach and reef that likes a west swell. For the first week, it’s a quiet story. We’ve got a 2 to 4 foot SSW swell running, but that damn west wind is blowing right onshore, just ruining the surface. The combined energy, though we don’t measure waves in those units, is on the low to middling side. It’s a frustrating wait. Water temp is what you’d expect for this time of year.
Then, late on the 25th of August, the whole picture changes. A new S swell hits over 6 feet, with a 16-second period. That’s a serious groundswell. Through the 26th and 27th, it holds at 6 to nearly 7 feet, with the wind turning offshore from the W or WNW. That is the moment. For the experienced crew, mornings are glassy and the break gets that big, clean, powerful look. The energy is through the roof. You know it’s going to be a proper session, but expect other surfers to have the same idea. On the 28th, the swell drops a little to 5 to 6 feet, but the wind goes cross-onshore from the SW, taking the shine off. Into the 29th and 30th, the swell fades to 4 feet and below, and the wind gets messy.
Rusty, signing off.

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.
