The Lowdown
Alright folks, Rusty here. Let’s have a look at what’s on the menu for Porsmilin over the next couple of weeks.
First off, the water is sitting at 65°, which is pretty much bang on average for this time of year, so no surprises there.
The next few days are pretty grim. We’ve got a lot of poor surf conditions and strong, messy winds blowing through the weekend and into the start of the week. The swell is trying to push through, but the wind is just ruining it. Sunday the 30th and Monday the 31st will see some size, but Sunday is a total write-off with onshore winds and a storm risk. Monday morning the 31st is a bit better – a 8ft swell from the west, period 10 seconds, and the wind is a gentle cross-off, keeping things clean. It’s still only a marginal call, but that Monday afternoon looks like the first real window: 7ft of west swell, 10-second period, clean conditions with a gentle cross-off breeze. The wave energy is solid at 942. That’s the first time it’s worth paddling out.
After that, we drop right off again. Tuesday and Wednesday are tiny and weak, with onshore winds. The combined energy falls to 77 and 43 on the 2nd and 9th, so there’s nothing doing. There’s a long gap of poor surf right through until the 11th of September.
Now, here’s where it gets interesting. Friday the 11th of September is the standout. The morning shows a 5ft swell from the west-northwest, but it’s a really long-period groundswell at 14 seconds, and the combined energy is a strong 1815. The wind is light and cross-shore, keeping it reasonably clean. But the real gold is the Friday afternoon: 8ft of west swell, 13-second period, combined energy of 2359. That’s a lot of power. With a light cross-off breeze from the north-northwest, it’s going to be clean. This is excellent surf for experienced surfers only – 8ft is expert territory, and that long period will make it suck hard and break heavy. This is a point break setup, so it should handle that long-period energy well. The crowd factor is listed as “sometimes,” so you might have a few others about, but if you’re confident, this is the session to aim for.
The 13th of September, Sunday morning, looks glassy and clean with a 4ft west swell, period 10 seconds, and no wind at all. That’s a sleeper session for a good, clean wave. The combined energy is 380, so it’s not huge, but for a fun, peaceful session, it’s a nice option.
To wrap it up: the best on offer is definitely Friday the 11th of September afternoon. That’s a serious swell, clean wind, and a lot of power. The Sunday the 13th morning is a good runner-up for a more relaxed, clean day. Everything else in the first week is a write-off unless you’re desperate.

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.
