The Lowdown
Alright, let’s get into it.
The next couple of weeks are looking like a bit of a mixed bag for Porsmilin, but there are a couple of windows where it’s going to be worth paddling out. We’ve got a decent run of swell coming, but the wind is going to be the main player here. The water is sitting at 63°F, which is pretty much normal for this time of year.
The first few days are pretty poor. We’re looking at some small, weak swell, and the winds are mostly on or cross-onshore. Tuesday the 16th gets a bit interesting in terms of size, but it’s blowing a strong breeze with it, which is just going to wreck it. That’s more of a kite-surfing day to be honest, with that 8ft of cross-off, but also 45 km/h winds. Not for the paddler.
The first real window I see shaping up is on Friday the 18th in the afternoon. The sun comes out, the wind drops right off, and we’ve got some clean, cross-off waves at 5ft from the WNW. The energy is moderate (627). It’s a bit of a rebuilding swell, but it looks like the best the first week has to offer. Before that, Saturday the 20th late afternoon and into Monday the 21st are the standout days. The 20th sees a solid pulse of energy with 8ft and a strong 1364 energy reading, but it’s a bit cross-on. The real gem is Monday the 21st. We’ve got morning and afternoon sessions showing 8ft and 7ft of clean, cross-off swell from the NW. Light winds, moderate energy (1208 and 1166), and it’s set to be a proper day. That’s the one to circle, it’s the best on offer.
After that, the surf settles back down. We’ve got a few days of smaller waves and average winds, but then on Wednesday the 23rd and into Thursday the 24th, there’s another clean spell. Wednesday morning looks good with a 5ft swell and light offshore winds, and Thursday morning is looking glassy with a 5ft swell. Those are nice, but nothing on the scale of Monday.
So, overall, the first week is a grind, but the light at the end of the tunnel is that Monday the 21st looks firing. It’s nearly two weeks out, so keep an eye on it, but it’s definitely the standout. The surf after that is more modest but still clean on the 23rd and 24th.

A general guide to surfing at Porsmilin can be found by selecting the local surf guide option on the grey menu.

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.
