The Lowdown

Alright folks, Rusty here. Let’s have a look at what’s on offer for Porsmilin over the next couple of weeks.

Right off the bat, we’ve got a bit of a slow start. The first real action worth paddling out for isn’t until Friday the 21st of August. Before that, it’s pretty flat and uninspiring, so sit tight.

Friday morning the 21st is where it’s at. Clear skies, a WNW swell pushing in at 6ft with a 10-second period, and the wind is a light cross-off from the NW at 9 mph. The water temp is about what you’d expect for this time of year, so no surprises there. The wave energy is moderate (512). This is the standout of the whole outlook – it’s clean, there’s some push, and it’s a sandbar that handles a SW direction swell well. Into Friday afternoon, the wind picks up a bit and the swell drops off slightly, but it’s still rideable.

Saturday the 22nd is a big letdown. Morning sees a drop to 3ft from the NW, and even though the wind is offshore from the NE at 6 mph, the energy is weak (124). The waves are just ordinary. By afternoon, the swell is tiny and messy.

From Sunday the 23rd all the way through to the end of August, it’s a bleak stretch. Swell sizes hover around 1ft to 1ft, and the wind is either onshore or cross-off with some strong gusts. There’s a period of stormy weather on the 25th and 26th with risk of thunderstorms and onshore winds, and even though the swell bumps up to 7ft on the Wednesday morning (26th) with strong energy (922), the onshore wind makes it a total mess. That’s a no-go for paddle surfing – that setup looks more interesting for kite surfing than paddle surfing.

The first week of September isn’t much better. We’ve got a string of days with tiny swell, onshore winds, and poor conditions. It’s a real blank run.

Then, finally, a glimmer of hope. Friday the 4th of September morning brings a return of WNW swell at 6ft, a 9-second period, and a light offshore wind from the NNE at 9 mph. The wave energy is moderate (471) and the conditions are clean. That’s your second best window, but it’s a long way out. The following Saturday morning (5th September) sees a bigger, longer-period groundswell from the WNW at 6ft with a 13-second period and very strong energy (1093). That’s a proper swell, but the wind turns onshore from the SSW, so it’s a bit of a gamble. At a sandbar, a long period like that can make the waves a bit too straight, but if the wind plays ball it could be a gem. Keep an eye on it.

All in all, Friday the 21st is your best bet. The rest of the window is mostly a write-off, but there’s a late promise on the 4th and 5th of September. Stay patient.

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.
