The Lowdown
Alright, folks, Rusty here. Let’s be straight with you. The next couple of weeks at Porsmilin are shaping up to be a bit of a mixed bag, with a long, flat spell to start before things finally crank up towards the end.
The first stretch is rough. We're looking at a whole lot of nothing for the first several days. From Wednesday the 5th right through to the 9th, don't even bother waxing up. The swell is tiny and the wind is messy, mostly cross-shore, which chops things up. It’s a write-off.
We finally start to see a pulse of life around Monday the 10th with some waist-high waves, but it’s still pretty ordinary. The wind is offshore in the morning, so it’s clean, but there’s just not enough energy in the water to get excited about. Tuesday and Wednesday are similar – small, clean, but you’ll be fighting sandbars for dribbly ones. The energy readings are low, telling you all you need to know.
There’s a slight build for Thursday the 13th and Friday the 14th, with the swell nudging up to around the 4ft to 4ft mark. The wind is cross-offshore, so it should be clean. The energy is climbing, but it still feels a bit underwhelming. It's surfable, but nothing to skip work for.
Then, mark your calendars for the real window. Saturday the 16th sees a proper push of W-NW swell, hitting around 6ft on the morning. The energy jumps right up, but there’s a bit of cross-shore wind on it, so it might be a bit lumpy. Sunday the 17th is a bit of a drop-off, then things look special for Monday the 18th. We’ve got a solid 7ft to 8ft of W-NW groundswell, and even though the period is a touch short, the energy numbers are big. The wind is cross-offshore and clean, which will make for some proper, grinding sandbar walls. This is definitely the standout window, but with surf that big and a sandbar, it’s pushing into expert territory. After that, it looks like the swell backs off again into Tuesday and Wednesday.
Honestly, with all the small, clean days early on and only that one decent to big day, this is a period for the patient. The water temp is sitting right around the 65° mark, which is pretty normal for this time of year.
So, the call is this: don’t get your hopes up for the next week, but keep an eye on the 18th. That’s the one.
Rusty.

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.
