The Lowdown
Alright, let’s cut to the chase. The next couple weeks are looking like a real patience tester. Not much on the cards, and what we got early on is getting chopped up by the wind. Most of the energy is coming from the south-southwest, but it's all over the place.
The first possible session is Monday the 7th, but it’s not one to get excited about. We’ve got a 6ft swell from the SSW, but a fresh cross-onshore breeze is going to wreck it, leaving it lumpy and messy. The combined energy is moderate at 1007, but it’s useless. Not worth paddling out. The water’s running at 73°, which is way warmer than usual for this time of year, so that’s a small consolation.
The rest of the week is more of the same – small, onshore, and poor. Tuesday drops to around 4ft, and Wednesday even smaller. There’s a hint of a longer period groundswell mid-week, but there’s no size behind it. The whole stretch through the weekend of the 12th and 13th is a write-off. Small swell and cross-shore winds that make everything a mess.
We finally get a break in the wind the following week. It eases and goes more offshore, and we start to see some clean, small waves. By the 16th, we’re looking at 3-3ft of SSW groundswell with light winds. It’s small, but it’ll be clean and glassy. The energy is on the low side of moderate (407-557), so it won't have much push.
Now, the one to wait for, the standout is Monday the 21st. The swell kicks back up to a bit over 4ft, coming from the SW, which is the right direction for this spot. The period is a long 18 seconds, so there’s some real push behind it. The combined energy jumps to 812, which is the most we’ll see in this whole window. The morning looks best with light offshore winds and clean conditions. This is the one. It’s a long way off, so don’t book the day off yet, but it’s got the most potential by a mile.
After that, it seems to fade back out. So, lots of closeouts and flat spells, a couple of clean small days mid-next week, and one promising swell at the end of the period. Keep your eye on the 21st. This is 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.
