The Lowdown
Alright, grab a coffee and listen up. Rusty here with a long look at Porsmilin.
To be honest, the next week or so is a bit of a mixed bag. We’ve got some solid swell coming in, but the wind is going to be a real pain for the most part. It’s not going to be all bad though, there's a couple of windows that look promising if you're patient. The water temperature is sitting at about 63°, which is pretty much average for this time of year, so nothing weird going on there.
Let's start with the immediate stuff. This Sunday, the 13th, is a write-off. We’ve got waves around 5ft from the west-northwest, but a cross-on shore is wrecking it. The combined energy is moderate at 634, but the surface is choppy. Monday the 14th is not much better – the swell drops to about 3ft and the cross-on wind is still there. Not worth paddling out for.
Tuesday the 15th sees the wind go cross-offshore from the northwest, which is a big improvement. The swell is about 6ft in the afternoon with moderate energy (563), and the report says “clean.” It’s a step in the right direction, but it’s still not firing.
Wednesday the 16th is where things get interesting. The swell is up to around 7ft from the WNW, and the combined energy jumps to a strong 1036 in the morning and 1215 in the afternoon. The wind is cross-off and clean, but the conditions are only described as “marginal.” This is a solid wave size, over 7ft, so it's for experienced surfers only. It's a bit of a shame the quality is not quite there.
Thursday the 17th and Friday the 18th are messy again. Thursday morning is cross-on and choppy, and Friday sees a huge 10ft swell with a very long 14-second period. That’s a lot of power – combined energy is a very strong 3273 – but the cross-on wind and chop will make it a battle. At that size, and with the wind, this is expert territory and honestly might be more of a kite-surfing show than a paddle session.
The next few days are a bit of a write-off with cross-shore and cross-on winds keeping the quality down, even with moderate swell around 6ft to 7ft.
Now, here’s the standout. Mark your calendars for Monday, the 21st of September. The morning is looking really good. We have a clean 6ft swell from the WNW with a long 13-second period, moderate-to-strong energy at 1134, and most importantly, light cross-offshore winds from the north. The report says “expect very good surf conditions,” and this is the only time that phrase appears. That’s the session to aim for.
The following days, Tuesday the 22nd, has some potential with a fresh offshore wind and a 8ft swell in the afternoon (energy 1929), but it’s marked as marginal. After that, the swell drops right off. From Wednesday the 23rd all the way through to Sunday the 28th, the waves are mostly under 4ft and the energy is weak. The end of the month on Monday the 28th sees a slight bump back up to 5ft-6ft with clean conditions, but it’s still marginal.
So to wrap it up: there’s some decent swell on the way, but the wind is the enemy most days. The one true standout is Monday the 21st of September. Get in the water then, because the rest of the fortnight looks pretty average.

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.

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.
