The Lowdown
Alright folks, Rusty here with the long-range outlook for the Porsmilin area. We’ve got a bit of a tough stretch ahead, but there’s a glimmer of hope for the more patient surfers among us.
The next week or so is looking pretty grim. We’re starting off this Wednesday, the 26th of August, with some messy, weak cross-on wind swell and poor surf conditions – not worth getting wet for. That pattern sticks around for days. We’ll see a bit of a bump in swell size from Thursday through Saturday, but it’s all accompanied by onshore or cross-onshore winds, keeping things choppy and ugly. Saturday the 29th gets a bit wild with a strong breeze and 8ft of windswell, but it’s lumpy and onshore, making it a real chore. The combined energy values are moderate to strong (up to 785), but it’s all poor quality. Honestly, for paddle surfing, it’s a write-off. With that much wind and swell, the setup at this sandbar might be more interesting for kite surfers.
We finally get a change on Monday, the 31st of August. The morning sees a clean 8ft swell from the WNW with a 9-second period, and a light offshore breeze from the NW. The conditions are clean, but it’s only a marginal forecast due to tide. The combined energy is very strong (1094), but at 8ft, this is only for experienced surfers. The afternoon drops off a bit in size and gets a cross-shore chop, so the morning window is the one to eye.
Then there’s a big gap with more poor conditions until a real standout appears on Friday, the 4th of September. The afternoon is the pick of the entire forecast. We’ll have a clean 5ft swell from the WNW, with a decent 10-second period, and a moderate offshore wind from the north. This is the only time we see a “good surf conditions” note. The water temperature is around 64°, which is about normal for this time of year.
Looking further ahead, the morning of Monday the 7th of September brings a very large 8ft swell from the west with a long 11-second period, and the combined energy is massive (1432). However, it’s onshore wind and a marginal call, so it’s a big, messy prospect for experts only. The following morning, Tuesday the 8th of September, shapes up nicely again with a clean 6ft swell and offshore winds, offering another solid, more manageable session.
So, to wrap it up: the first week is a bust. The standout is the afternoon of Friday, the 4th of September, with clean, offshore conditions and a fun-sized swell. The mornings of Monday the 31st of August and Tuesday the 8th of September are also worth a look if you’re keen. Keep the faith, the surf will turn.
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.
