Alright, grab a seat. Rusty here, and I’ve been digging through the numbers for Porsmilin. The next 16 days are a bit of a slow burn, mostly flat with a couple of tiny windows. Let’s be straight about it.
The first real chance to get wet is a very brief one on Friday the 10th. The morning shows a small 3ft swell from the WNW with a 9-second period, pushing a moderate amount of energy (151). The water is a touch warmer than usual at 65°, about 3° above average for this time of year. A light breeze from the ENE will keep it clean. The afternoon cleans up even more with a 12 mph offshore wind from the N. It’s tiny, but it’s the best we’ll see for a while.
From Saturday the 11th right through to the morning of Friday the 17th, it’s a flat spell. The swell drops to 1ft or less, the energy is in the low double digits, and the wind is all over the shop. It’s just poor. Don’t bother.
We get a little bump on the 18th. Saturday morning shows a 3ft swell from the SSW with a short 6-second period. The energy is moderate (104), and the wind is a light offshore from the N. It’s surfable, but that short period will make it weak and crumbly.
Now, the one to watch is the 24th and 25th of July. On Friday the 24th, the morning looks promising. We’ve got a 3ft swell from the WNW with a 10-second period, and the energy hits a solid 199. The wind is a gentle cross-off from the NW, so it’ll be clean. The afternoon builds, with the swell hitting 4ft and the energy at 303, but the wind swings to a cross-shore from the WNW, putting a chop on it.
Saturday the 25th is the big one. The morning shows a 5ft swell from the WNW with a 10-second period, and the energy is a massive 502. The problem is a light onshore wind from the SSW. The afternoon holds 5ft with an 11-second period and energy at 511, but the wind picks up to a 12 mph onshore from the SW. For a sandbar break like Porsmilin, that’s going to be a big, messy, blown-out mess. It’s expert-only territory, and honestly, with that much swell and onshore wind, the kite surfers are going to have a much better time than we are.
So, in short: A couple of tiny, clean windows on the 10th and 18th for a quick fix. The big swell on the 24th and 25th has the size but the wind will wreck it. The 24th morning is your best shot for a decent, clean wave.
Keep your eyes on the horizon.

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.
