The Lowdown

Alright crew, Rusty here again. Let’s break it down in feet and miles per hour.

The first few days are a waste. Tuesday morning has a 8ft swell from the W, but a 45 mph NNW wind is howling, so forget it. Wednesday cleans up a bit, but it’s not until Wednesday afternoon that we get a decent window.

The first real highlight is Thursday 11 September morning at Porsmilin. Clean 5ft swell from the W, 9 seconds, with a light cross-offshore breeze. That’s a proper session for the average surfer.

Friday 12 September is the one to circle. Saturday morning is glassy — a 5 mph NNE breeze, clean 4ft swell from the NW, 10 seconds. The water temp is about 64°, which is normal for the season. The wave energy is moderate (392) but the surface is dead flat. That’s the best-looking wave in the whole 16 days.

Saturday afternoon gets a bit bigger, 6ft from the WNW with a 13-second period and strong energy (1120), but the wind swings cross-shore, so it’s a bit bumpy. Still a solid wave for the more experienced.

Sunday and Monday are a write-off with onshore winds and chop. The second week is mostly small, with wind constantly blowing cross-off. The 19th and 23rd of September have pulses around 4ft, but nothing special.

The standout is Saturday morning 12 September at Porsmilin — glassy, clean, and fun. Mark it.

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.
