The Lowdown

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

Right off the bat, we’ve got a bit of a wait. The first proper session that’s worth a mention is Thursday morning, the 13th of August. The swell is a clean 4ft from the west with a 11-second period, delivering a moderate 277 combined energy. The wind is a light cross-offshore from the northwest at 9 mph, so the wave face will be smooth. The water temp is about average for this time of year, nothing weird going on. That’s the best you’ll see for a while, so if you can get out, make it count.

Thursday afternoon, the wind picks up to 13 mph and the quality drops off a cliff. Not worth it.

Friday the 14th sees the swell drop to 3ft from the west, period down to 9 seconds, and the energy is weak at 136. The wind is light cross-off in the morning, so it’s rideable, but the conditions are just ordinary. You’ll get a wave, but it won’t be a memory.

Saturday the 15th brings a bit more hope in the morning. A 3ft swell from the west, short 8-second period, but the wind goes offshore from the NNE at 13 mph. That’s clean, glassy conditions, and the energy is moderate at 168. It’s surfable, but the short period means it’ll be a bit crumbly. Still, a clean morning is worth a paddle.

Then we hit a big dry spell. From Sunday the 16th all the way through to the end of the month, it’s mostly tiny, weak, or onshore junk. There’s a few days with onshore winds and swell under 3ft, and the energy readings are pitiful – we’re talking 15, 58, 86. The wind is all over the place, from onshore to cross-off, but the swell just isn’t there.

Now, there is a little flicker of life on Wednesday the 19th afternoon. The swell jumps to 4ft from the WNW, 10-second period, and the energy is a solid 327 (moderate). The wind is cross-off at 16 mph, so it’s clean. But the score is marginal, and the tide might be working against you. If you’re desperate, it’s a look, but don’t expect a classic.

Thursday the 20th is a bit bigger, 5ft from the WNW, with 8-9 second periods and energy in the 347-372 range. Again, it’s clean with cross-off winds, but it’s still marginal. This is getting into the size where beginners might feel a bit pushed around, and the short period means it’ll be a bit fat and dumping.

The standout – and it’s the only real highlight in the whole 16 days – is Friday morning, the 21st of August. A 5ft swell from the northwest, 10-second period, and the combined energy is a strong 474. The wind is light cross-off from the northwest at just 6 mph. That’s clean, glassy, and the swell has some punch. It’s not huge, but it’s the best quality wave of the entire forecast. Get on it.

After that, the 22nd and 23rd are tiny and messy. The 24th has a bigger swell, 6ft-6ft from the west, but the wind is cross-shore and the scores are a flat zero. That’s a write-off. The 25th is clean but small, and the 26th is a full-on blown-out mess with 25 mph onshore winds and a 6-second period. That’s kite-surfing territory, not paddle surfing.

The very end of the month, the 27th and 28th, are flat and clean, but there’s no energy – 48 and 39 combined energy. You’ll be staring at a lake.

So, to wrap it up: Thursday morning the 13th and Friday morning the 21st are your best bets. The 21st is the pick of the bunch. The rest of the window is a long, quiet stretch. Fairly normal for this area in late summer, but it never stays poor for long. Keep an eye on the forecasts.

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.
