The Lowdown

Alright, Rusty here. Let’s have a look at what’s coming up for Porsmilin.

Right now, there’s nothing doing. Monday the 14th is flat with poor conditions, and Tuesday the 15th isn’t much better – small waves and messy winds. We’re looking at a real dry spell until Wednesday the 16th, when things start to pick up but still aren’t great. From Wednesday the 16th through to the weekend of the 19th, we’ve got building swell but the wind is mostly cross or cross-onshore, keeping the surf lumpy and average. On Friday the 18th morning, there’s a big pulse of 9.8ft swell from the WNW with a long 14-second period and a combined energy of 3066 – that’s a lot of power – but the wind is cross-shore and it’s only rated as marginal. It’s more of a kite-surfing setup than a clean paddle session.

The standout window arrives on Monday the 21st. That morning, Porsmilin wakes up to 6.6ft of WNW groundswell, 14-second period, with glassy conditions and easterly winds at just 3 mph. The combined energy is a solid 1411 and the water temp is about average for this time of year. This is your session – clean, powerful, and well-shaped for intermediates. The break is fairly consistent and fairly exposed to the SW swell window, which lines up nicely with the WNW direction. It can get crowded sometimes, so get in early. Monday afternoon stays good too with clean cross-offshore winds and 5.6ft waves.

Tuesday the 22nd still has clean waves but smaller at 3.6ft, and by Wednesday the 23rd the swell drops off and winds strengthen. The second week is quiet – from the 24th onward it’s small, messy, and mostly not worth your time, with only tiny waist-high dribble and glassy moments on Sunday the 27th afternoon that are barely surfable.

Best bet: Monday the 21st morning at Porsmilin – glassy, solid groundswell, clean conditions. That’s the one.

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.
