The Lowdown
Alright, Rusty here, let's chew the fat on what's coming down the pipe for the next couple of weeks. It's a bit of a saga, so stick with me.
Right off the bat, the next few days are a tough slog. We've got a slow start with nothing really on offer. Monday the 14th and Tuesday the 15th are write-offs – small, messy, and the wind is all wrong. You're looking at a couple of days where you might as well do something else. The water temp is sitting around 63°, which is just about normal for this time of year, nothing strange there.
Wednesday the 16th sees the swell start to build, but the quality isn't there. We're looking at an 8ft swell from the WNW on Wednesday morning with a 10-second period, but it's accompanied by a solid 16 mph cross-offshore wind, keeping the wave quality marginal. The wave energy is getting serious though, hitting 1186 (moderate to strong). This isn't beginner territory – anything over 5ft gets a bit much, and at 8ft, it's really just for the experienced crew. The afternoon cleans up a little with a 7ft swell and a longer 11-second period, but it's still only rated as marginal.
Thursday the 17th is a step back. A messy 19 mph cross-onshore wind kills any chance of clean surf, even though there's a 7ft swell with 987 units of energy. Friday morning the 18th looks tempting on paper – a 10ft swell with a very long 14-second period, and a massive 2965 combined energy reading – but that cross-shore wind creates a chop that's no fun for a paddle. Honestly, that setup looks more interesting for kite surfing than paddle surfing.
The first real standout appears on Sunday the 20th. The afternoon session is the pick of the first week. A 7ft WNW swell, but it's pushing a very long 15-second period, and the combined energy is pumping at 2691. The wind finally plays ball – light 6 mph cross-shore breeze, just enough texture to keep it glassy. That's going to be clean and powerful. For Porsmilin, a sandbar setup, that long period means the waves will have real shape and punch, though the sets might be a bit spread out.
Now for the *real* highlight. Mark your calendar for Monday the 21st. Monday morning is the moment. We've got a 6ft swell from the WNW, with a solid 13-second period, and 1283 units of moderate energy. But the wind is the hero here – a glassy 3 mph cross-offshore from the ENE, described as "Slight air." That is about as clean as it gets. Expect very good surf conditions. It's not huge, but it'll be perfect, lined-up waves. Crowds are possible at Porsmilin on a morning like that, so get in early.
The rest of the second week is a bit of a tease. Tuesday the 22nd has clean conditions with offshore wind, but the swell drops off to 3ft to 4ft. Then we see a spike on Friday the 25th – a 8ft WNW swell with a 14-second period and 2226 energy, but that's paired with a strong 19 mph cross-offshore wind. It'll be clean, but stormy. Saturday and Sunday have the size (10ft on the 27th) but onshore winds ruin it again.
So to sum it up: the first few days are a flat, windy dud. The first real standout is Sunday afternoon the 20th, but the absolute best on offer is Monday morning the 21st. After that, it's a waiting game with a few promising but wind-affected pulses. Stay patient, and don't sleep on that Monday glass-off.
Rusty.

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.
