The Lowdown
Alright, grab a coffee, this is the imperial version of the same story.
Rusty here, and I’ve been looking at the charts for Porsmilin. It’s a bit of a mixed bag for the next couple of weeks, but let’s break it down.
We’re starting off with a bit of a flat spell. The surf is small and pretty average for the first week. The water temp is sitting at 66°, which is bang on average for the time of year, so no need to dig out the thick rubber just yet. The main window of interest doesn’t really open up until the very end of the run.
For the first few days, from Friday the 14th through to the middle of the next week, it’s all small, short-period wind swell. The waves are around the 3ft mark on Friday morning, but the wind is cross-off, and the energy is weak (136), so it’s just a grovel session. Saturday the 15th sees a slight bump with some clean 4ft waves and a true offshore wind, but the period is a short 8 seconds, so it’ll be fat and sectiony. It’s really just a knee-to-waist high option for a paddle. The rest of that first week drops right off into the dirt, with barely anything rideable. We’re talking about a gap of dead flat days right through Sunday and most of the following week, with only ankle-snappers on offer.
Now, the real story is the second week. We finally get a pulse of energy. Thursday the 27th looks like the standout. The swell comes up to 6ft on the Thursday morning, but it’s a bit grubby with a cross-shore wind. The real gem is the Thursday afternoon. The swell stays solid at 6ft from the west, mid-period at 9 seconds, and the wind swings to a gentle offshore from the NNE. The energy jumps to a solid 481 (moderate), and the forecast is for “good surf conditions.” This is the one to circle on your calendar. It’s not a massive groundswell, but the combo of size, clean wind, and decent period will offer some proper, fun waves at Porsmilin.
The following Friday and Saturday drop back down to small and unexciting, so that Thursday afternoon window is the only true highlight in the whole 16-day outlook. If you only get one session, make it the 27th afternoon.

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.
