The Lowdown

Alright folks, Rusty here. Let’s have a look at what’s on the menu for Porsmilin over the next couple of weeks. I’ll be straight with you – it’s a slow start, and we’re going to have to wait a bit for the good stuff.

Right now, we’re looking at a real dry spell. For the first week and a half, from Saturday the 15th through to around Monday the 24th of August, it’s pretty grim. The swell is tiny, mostly below 3ft, and the periods are short, around 7 to 8 seconds. That’s just weak, windswell energy with no push. The wind is a constant cross-off or cross-shore, which keeps the surface clean, but there’s just no wave to ride. The combined wave energy is pathetic, mostly in the double digits (18 to 107) – it’s like a lake out there. On Tuesday the 19th, we get a spike of energy (379) with a 3ft swell from the WNW and a longer 11-second period, but the forecast flags it as marginal. The wind stays cross-off, so it’s clean, but the swell is too weak and inconsistent to really get excited about. Basically, you’re looking at almost nine days of flatness.

Now, things finally start to wake up on Tuesday the 25th of August. The morning shows a 5ft W swell with a 10-second period and light offshore NW wind at 6 mph. The combined energy jumps to 479 – that’s something you can work with. That’s a solid, clean morning session. The afternoon pushes up to 6ft from the WSW, but the wind picks up to a moderate cross-off, which will chop it up a bit. Still, that’s a decent day after a long wait.

The real standout, the one you’ve been waiting for, lands on Saturday the 29th of August. Saturday morning brings a 8ft swell from the SSW with a short 7-second period, but the wind is light offshore from the NE, only 6 mph. The energy is pumping at 842. That’s a powerful, clean wave. But here’s the thing – by Saturday afternoon, the swell jumps to a massive 15ft from the SW with an 11-second period and a combined energy of 4992. That’s a serious, heavy groundswell. The file says it’s too big for this break, and I agree. That’s for experts only, and even then, it’s going to be closing out. The morning session is the pick for experienced surfers.

Then, on Sunday the 30th, we get a 10ft SW swell, 9-second period, with a light NNE offshore breeze at 9 mph. That’s 1441 energy, clean, and the forecast says excellent for experienced surfers. That’s your best bet. It’s a big, powerful wave, but the offshore wind will keep it clean.

So, to sum it up: the first week and a half is a write-off. The best windows are the morning of Tuesday the 25th for a smaller, cleaner day, and the morning of Sunday the 30th for the real deal. The Saturday afternoon swell is too big for this break. The water temperature is about average for this time of year, so no thermals needed.

Stay patient, and I’ll see you out there for that Sunday session.

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.
