The Lowdown
Alright, let’s get into it. Not gonna lie, looking at this 16-day window for Porsmilin, it’s a bit of a tough watch. There’s a decent little window early on, but then a long, quiet spell before a late flare-up that’s got some power but comes with its own problems. Let’s break it down.
The main event, and really the only time I’d be genuinely keen, is Thursday morning, August 13th at Porsmilin, a sandbar set-up. We’ve got a clean 4ft swell rolling in from the west with an 11-second period, giving it some proper shape and push. The wind is a light cross-off from the NW at 9 mph, which is going to leave the faces looking pretty. Combined swell energy is moderate at 277, so there’s enough grunt to make it fun. The water’s sitting at 66°, which is basically spot-on average for this time of year, so no surprises there. This is your best chance by a long shot.
After that morning, it drops off quickly. Thursday afternoon gets gusty and the quality goes south. Friday morning, August 14th, sees the swell drop to 3ft (west, 9-second period) and the energy falls away to 136 – it’s there but pretty average. The rest of that day into the weekend is a slow decline. Saturday morning, August 15th, actually sees a bump to 4ft from the WNW with a shorter 8-second period, and the wind is offshore from the north at 19 mph, which sounds clean, but the combined energy is a moderate 296 and the score suggests it’s marginal. It’s probably a bit onshore-bent and short-period, not holding together well.
Then we hit the big gap. From Sunday morning, August 16th, all the way through to Saturday, August 22nd, there’s nothing worth paddling out for. Swell heights barely hit 3ft, periods are short, the energy is weak (down to 20 at one point), and the conditions are either poor or just flat. That’s over a week of very quiet water. The only tiny flicker is Friday morning, August 21st, with a 2ft NW swell and 8-second period, but it’s still not enough to get excited about.
Things start to look different on Sunday, August 23rd. The swell fires up to 7ft from the WNW, with combined energy jumping to a strong 594. But here’s the rub – the wind is onshore from the south at only 3 mph, and the condition is labeled ‘unknown’, which usually means messy. This is a bigger, stronger swell, but it’s not going to be clean for a sandbar. For an experienced surfer, it might hold some power, but for anyone else, this is in the too-big-and-sloppy zone. The energy stays high on Monday the 24th (7ft, 752 energy) but the wind becomes a moderate cross-onshore, churning it up.
The last few days, from August 25th to 28th, show some serious wind. We get a strong and even near-gale offshore wind from the northeast towards the end, with swell bumping up to 6ft and energy hitting 855 on Friday the 28th. The catch? At 25-31 mph of offshore wind, that’s going to be incredibly hard to paddle into and will likely be a battle to even get out back. The wave quality might be clean, but it’s only for the fittest and most experienced.
So, bottom line: if you want clean, fun, surfable waves, you paddle out Thursday morning, August 13th. That’s your standout. Everything else before the 23rd is quiet, and after that, it’s either too messy or too windy for most. The late energy on the 28th has power, but it’s an expert-only proposition.

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.
