Alright, Rusty here. Let's get into what we've got on offer for Porsmilin.

We're looking at a real mixed bag, and to be honest, the first week is pretty slim pickings. You've got a small window early on that’s surfable but nothing to write home about, then a proper lull. The second week tries to fire up a bit with some bigger, more powerful swell, but the wind is going to be a problem.

Our only real play in the first few days is Wednesday morning, July 8th. Porsmilin is a sandbar setup, and it’s fairly exposed but it needs a clean window. You’re looking at a small 3ft swell from the WNW with a 10-second period and only weak to moderate energy (109). The water temp is 64°, which is a touch warmer than normal for this time of year. The key here is that wind is light at 3 mph from the north – that's going to be clean, glassy conditions. But at that size, it's really just for getting the fins wet and having a gentle cruise. After that, the wind absolutely guns it on Wednesday afternoon and stays strong through Thursday and into the weekend. Even though the wind stays offshore or cross-off, anything over 12 mph makes the surface bumpy, so quality drops off hard. Friday morning is the next half-decent look with a 3ft WNW swell and a light cross-off breeze (9 mph), but again, very ordinary conditions overall.

From Sunday, July 12th, things really flat-line. We’ve got several days with barely a bump, and the energy readings drop into the low double digits. The swell just disappears until the middle of the following week. It’s a proper stretch of flat or near-flat conditions from the 12th through the 19th. You’d be better off waxing your board or checking the forecast for somewhere else.

Now, on Thursday morning, July 23rd, things get interesting but difficult. We finally get some proper energy, with the combined swell energy hitting a strong 411. The swell is a 7ft NW swell, which is going to be powerful and a bit raw. That size is getting into expert territory, especially with a short 7-second period which means it’ll be a bit dumpy and chaotic. The problem? The wind is 16 mph from the SE – that's cross-onshore. It’s going to be bumpy and choppy. The sea state is described as moderate cross-onshore and choppy, so don't expect any classic walls. The afternoon steps it up to a 8ft swell with 790 energy, but it’s onshore wind from the SSW at 16 mph, which will blow it out completely. Honestly, this setup looks more interesting for a kite session than a paddle session given the size and the grim wind for Porsmilin's sandbar.

So to wrap it up: The absolute standout is the Wednesday morning, July 8th session for the clean, glassy vibe on a tiny wave. It’s the only real quality window. After that, it goes flat for over a week. The big swell on July 23rd is powerful but too windy to be any good for a decent surf. It’s a tough outlook, lads.

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.

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.
