The Lowdown

Alright, this is Rusty, and I’m lookin’ at the next couple of weeks for our local stretch. Let’s be real, it’s a bit of a mixed bag, but there’s definitely some sessions worth paddling out for.

We’ve got a bit of a slow start, but things kick off on Saturday, the 5th of September, with some solid energy. The main spot to have on your radar is Porsmilin, a sandbar set-up. Saturday afternoon brings a clean, cross-off breeze from the NW at just 6 mph, so the surface will be nice. We’re looking at a 6 ft swell rolling in from the WNW with a solid 12-second period. The combined energy is pumpin’ at 1034, so there’s plenty of push. This is the standout of the whole outlook – the wind and the swell are gonna line up for some proper fun waves. Water temp is sitting around 63°, which is pretty much what you’d expect for this time of year.

Now, don’t get too excited about Sunday the 6th. Morning is a cross-on mess, dropping to 4 ft with a choppy 10-second period. The afternoon is even worse with an onshore wind. Monday the 7th has size – we’re talking 7 ft and 7 ft from the west with a 13-second period – but the wind is cross-shore and there’s a bit of chop. The combined energy is huge, over 1200, but the quality is a bit off, so it’s a day for the experienced crew only if you’re keen on a challenge.

Tuesday the 8th is a write-off in the morning with rain and onshore wind, but the afternoon cleans up nicely. Light NW wind, cross-off, with a clean 4 ft wave. Not huge, but it’ll be fun if you’re desperate for a paddle.

From Wednesday the 9th right through to Friday the 11th, it’s pretty average. Mostly small, short-period slop or onshore wind making a mess. There’s a pulse on Saturday the 12th with a clean 5 ft wave, but the wind is up around 16 mph, so it’ll be a battle.

Now, if you can wait, keep your eye on Sunday the 13th. The morning session is looking magic. Glassy conditions with a 6 ft W swell at 10 seconds. The combined energy is solid at 538, and with no wind, the waves will be smooth as butter. That’s your second real standout, and it’s a good one.

The week after that, the 14th through the 20th, is pretty slim pickin’s. We get a few pulses of clean, offshore wind on the 16th and 17th, but the swell drops right off to around 4 ft or less. The energy gets weak, and by the 20th we’re looking at tiny 2 ft waves. There’s a glassy morning on the 18th with a 4 ft swell, but it’s just not got the grunt for a proper session. Honestly, after the 13th, it’s a quiet run until the forecast changes.

Signing off,
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.
