The Lowdown

Right folks, let's have a look at what Porsmilin's got cookin' over the next couple of weeks. It's a bit of a mixed bag, to be honest, with plenty of wind to deal with for most of it. The good news? There's a couple of days that look like they could really fire, especially if you've got a bit of patience.

Alright, kicking things off now, and it's pretty grim. Tuesday the 25th and Wednesday the 26th are a write-off. You've got onshore winds and messy, weak surf. That combined energy is barely registering, so honestly, don't even bother paddling out. There's a brief moment Wednesday afternoon with glassy conditions, but the swell is tiny at 2ft from the SSW with a short period, so it's just not worth it.

Thursday the 27th and Friday the 28th... look, the swell starts to pick up a bit, hitting 6ft to 8ft from the SW and W. The energy is getting into the moderate range. But the wind is just all wrong – onshore or strong cross-offshore. Friday morning might offer a cleaner look with a cross-off breeze, but it's still a bit of a scramble for a marginal score. Not what we're after.

Saturday the 29th through to Thursday the 4th of September is essentially a blank run. The wind is relentless. Onshore, cross-onshore, strong cross-shore – it's all lumpy and choppy. The swell is there, jumping up to 7ft to 8ft at times, but it's blown out. Honestly, for most of this period, the setup looks more interesting for kite surfing than paddle surfing.

Now, hold onto your hats, because Saturday the 5th of September is your standout day. Saturday morning is the one to circle. We've got a clean 8ft swell rolling in from the WNW, with a long period of 10 seconds, and get this – a light offshore breeze from the NNE. The combined energy is strong. This is going to be proper groundswell, so it'll be a bit more lined up at the sandbar. It won't be easy for beginners at that size over 5ft, but for the rest of you, this is the call. Crowds are possible, so expect company. The water temp is about average for the time of year.

Then Sunday the 6th of September keeps the swell from the WNW at 7ft, but that wind swings around to a strong cross-onshore, so the magic is gone.

The final real event to mention is Monday the 7th of September. Monday afternoon sees a monster. A 20ft swell from the W with an incredible 18-second period. That's a very long period groundswell. The energy is off the charts. But, and it's a big but, the forecast says it's predicted to be too big for this break. That is strictly for absolute experts only, and even then, you'd want to know your spot inside and out. It's clean with a strong cross-offshore wind, but it's a beast.

Tuesday the 8th and Wednesday the 9th of September see the swell drop back but it's still too big for comfort (8ft to 10ft) and the onshore winds return again, so we're back to messy conditions.

So, to wrap it up: the pick of the entire forecast is hands down the morning of Saturday the 5th of September. Get in the water. Otherwise, it’s a long wait.

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.
