The Lowdown
Alright folks, Rusty here. Let’s have a look at what’s on the cards for Porsmilin over the next couple of weeks.
It’s a bit of a slow start, to be honest. We’ve got a run of days with very little to get excited about right through the end of August and into the first days of September. The wind is mostly onshore or cross-onshore, and the swell is small and weak. The energy is low, with combined energy readings mostly in the double digits and low hundreds – not enough to push a decent wave. It’s pretty much flat or messy. That’s a solid gap of around a week where you’d be better off doing something else.
The first real glimmer of hope shows up on the morning of Tuesday, the 1st of September. The wind swings to a light cross-offshore breeze from the NW, and the water is cleaning up. We’re looking at a clean 1.4m swell from the west with a moderate period of 10 seconds. The combined energy here is 377 (moderate), and it’s offering some proper shape. That’s your best bet in the first week – a solid, clean morning session. The afternoon gets a bit marginal with a lighter cross-shore, though.
The pattern tries again on Thursday morning, the 3rd of September. Another clean morning with a cross-offshore NW wind, and a similar 1.6m WNW swell, period of 9 seconds, and energy of 366 (moderate). It’s a bit of a repeat of Tuesday, but the winds are a touch stronger. Still a good option for a paddle.
Now, the standout period looks like it’s building towards the end of the second week. Sunday, the 6th of September, we’ve got a solid 2.2m WNW groundswell rolling in with a 10-second period. The energy is up there – 1038 (strong) in the morning. The wind is cross-shore, so it’s not glassy, but it’s manageable. The afternoon lightens up, making it more appealing. This is a big step up in power.
Then Monday, the 7th, we see the swell period stretch to 11 seconds, and the energy is a massive 1007 to 1141 (strong). The swell holds at 1.7m to 1.4m, but with that longer period, the waves are going to have more punch and better shape. The wind is light and cross-shore, which is a major positive for clean faces. This is arguably the best quality window of the whole forecast – a long-period groundswell with light winds.
Now, there’s a massive outlier on the 8th of September. The guidance says the swell is predicted to be too big for this break at 3.5m from the west with a 15-second period. The energy is through the roof at 6044 (very strong). That’s expert-only territory, and even then, at a sandbar, a long-period swell that size can be a washing machine. It’s a warning, not a recommendation.
So, for the whole outlook, your real standout is the Monday morning, the 7th of September. You’ve got a long-period, high-energy WNW swell, clean with light wind, and the Porsmilin sandbar should handle that direction well. The crowds are “sometimes” here, so you might have company, but it’s worth it. That’s the one to pencil in.
Stay safe, watch the tides, and I’ll see you in the water.

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