The Lowdown

Alright, me hearties, Rusty here with the lowdown. Let's be honest, the outlook for Porsmilin is a bit of a flat one. We're looking at a long stretch of time with nothing worth paddling for, about 8 days of poor conditions before anything even looks like a wave. The good news is, when the swell does try to show up, the winds look like they might be in our favour.

Alright, let's start with Monday, August 3rd. We've got a tiny 2ft swell from the WSW, but the wind is a cross-on, the water is a bit cool at 65°F, and the combined energy is a measly 69. It's a no-go, same for the afternoon. Tuesday the 4th sees a jump in size to 4ft, but it's shifty, with a 16 mph onshore wind and a 7-second period. The energy climbs to 190, but it's ugly and choppy. Not for paddling, mate.

Wednesday the 5th is the most interesting day of the whole forecast, but it's still a tough one. The morning brings a 6ft swell from the W, with a combined energy of 882. That's some serious juice, but it's getting hammered by a 12 mph cross-on wind. The period is only 8 seconds, so it's a messy windswell. This is one for the big-wave crew who don't mind a battle, but for the average surfer, it's a kite-surfing day. The afternoon cleans up a touch to a cross-shore, but the energy is still high at 723, and the waves are closing out.

Thursday through to August 10th is a slow grind. We see a few clean mornings with offshore winds, especially on the 8th, 9th, and 10th, but the swell is tiny, never getting above 3ft. The energy is weak, hanging around 100 or less. You could get a log out on the 10th morning with a 3ft WNW swell, light offshore wind, and clean conditions, but it's going to be a knee-high dribbler.

After that, from August 11th right through to the end of the 18th, it's a total flat spell. The swell drops to 0.7ft or 1ft, the energy is in the single digits or teens, and the wind doesn't matter because there's nothing to ride. The entire second week is a write-off.

So, what's the call? The only standout, and I'm using the term loosely, is Wednesday, August 5th for the swell size. But it's a messy, powerful windswell, and the wind is wrong. If you're an expert looking for a challenge, the morning might offer some big, lumpy sets. For everyone else, the best bet is to take the August 10th morning session on a longboard if you're desperate for a paddle. The 3ft WNW swell with a clean, offshore breeze will be the only time you'll see a clean wave face, even if it's small.

Honestly, this is a tough stretch for Porsmilin. The consistency is there in the offshore winds towards the end of the first week, but the swell just isn't playing ball. Keep an eye on the forecasts, but don't hold your breath.

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.
