The Lowdown

Alright folks, Rusty here. Let's have a look at what the next couple of weeks are shaping up to be for Porsmilin. It's a bit of a mixed bag, but there are some absolute crackers hiding in the back half of the forecast.

The first few days are a washout, to be honest. Monday morning the 7th is a write-off with a messy, choppy 7ft cross-on swell from the W with a moderate breeze. The combined energy is a hefty 1372, but it's all wind-blasted slop. You’d be better off staying in bed.

We finally get a sniff of something decent on Monday afternoon, the 7th. The wind swings light and cross-offshore from the NW, cleaning up that same 7ft W swell. The energy is still serious at 1285, and it’s a 13-second period groundswell, so it’ll have some punch. This is a proper window of clean, lined-up surf. Don't sleep on it.

Tuesday the 8th starts with a fresh cross-off breeze from the NNW, but the wind is howling at 35 km/h, making it a battle even if the waves are clean. The swell drops to 6ft. You’d have to be pretty keen. By Tuesday afternoon, the wind is still strong and the swell period has dropped to a short, weak 8 seconds, making it a total dud.

Wednesday the 9th is a bit of a tease. Clean, cross-off surf all day from the NW with 6ft of swell in the morning, dropping to 5ft in the afternoon. The energy is moderate (765 and 587), and the period is a solid 10 seconds. It’s surfable, but not the standout.

The rest of that week into the weekend is a poor run. Small, weak, and blown out. A few waist-high waves on Friday the 11th, but nothing to write home about.

Hold onto your board, because the real action kicks off on Sunday the 13th. The morning is a bit average, but Sunday afternoon sees a 5ft WNW groundswell, with a 13-second period, and a light cross-off breeze from the NW. The energy is building (799) and the conditions are clean. It’s a very good session.

Monday the 14th is a letdown, with small, weak waves.

Then we get into the goods. Tuesday the 15th sees a nice 7ft WNW swell pushing through, but it's blown out by a moderate breeze. The energy is strong (1182 and 1077), but the wind is a factor.

Now, mark your calendar for Thursday the 17th of September. This is the pick of the bunch. We’ve got a 8ft WNW swell with a 10-second period, and the wind is a light, cross-off breeze from the E. The combined energy is a massive 2460, and it’s flagged as "excellent surf conditions for experienced surfers." This is a serious, powerful swell. At 8ft, it’s expert territory, but the clean conditions will make for some absolute bombs. The afternoon holds at 8ft with the same clean cross-off vibe. This is the one.

Friday the 18th of September is also a beauty. The swell is 7ft from the WNW, but the wind is glassy – a 5 km/h southerly. That’s a no-brainer for a super clean, smooth session. The energy is still good at 690.

The following weekend has some solid options as well. Saturday the 19th has a clean 7ft WNW swell in the morning, and the periods are a decent 10 seconds. The wind is a gentle cross-off from the NNW. It’s a great option for the weekend.

The surf then tails off into the last week of the forecast, with smaller, cleaner but ordinary waves from the 20th onwards.

So, to sum it up: the first few days are a write-off. Look for that Monday afternoon window on the 7th for a quick hit of clean, punchy surf. But the absolute standouts are Thursday the 17th of September for the biggest, most powerful, clean swell of the period, and Friday the 18th of September for the glassy, smooth conditions. Get on it.

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.
