The Lowdown

Right, grab a coffee, mate. Rusty here. Let’s have a proper look at what’s cookin’ for Porsmilin over the next couple of weeks.

Look, I’ve gotta be straight with you – we’re in for a lean spell before things get interesting. The first real chance of a paddle isn’t until Wednesday morning, the 5th of August, with a 6 ft swell from the west. It’s clean with a cross-offshore breeze, but the period is short and the energy is only moderate (294). Wednesday afternoon hangs in there with a 5 ft west-northwest swell, but it’s all pretty marginal. Honestly, for the first week, it’s a real struggle. The water temp is sitting at 65°F, which is bang on average for this time of year – no complaints there.

From Thursday the 6th right through to Monday the 17th of August, the surf is tiny or poor. There are a few mornings with glassy conditions, like Tuesday the 11th with a 2 ft pulse and east wind, but it’s just not enough to get excited about. The second week is a write-off for waves, with constant poor surf conditions and low energy. The swell energy is weak, often under 100, and the wind is mostly cross or onshore. It’s one of those frustrating runs where the forecast just doesn’t line up for us.

Now, here’s the bit that’ll get your attention. The standout window is right at the end. On Monday the 18th of August, the morning is looking *very* interesting. We’ve got a solid 10 ft swell from the west, with a period of 9 seconds, and the combined energy is a massive 1539. That’s strong, powerful stuff. The wind is blowing fresh offshore from the north-northeast, so it’ll be clean and lined up. But listen – 10 ft is expert territory. This is not for the faint-hearted or beginners. It’s a sandbar break, so at that size and with a short period, it’ll be pitching and hollow. The rating flags it as excellent for experienced surfers, so if you’ve got the skill, that’s the session.

Tuesday the 19th of August shows an 12 ft west-northwest swell in the morning, with even bigger energy (2290). However, the wind is a light cross-off, and the forecast warns it might be *too big* for this break. It’s still a huge, powerful swell, but it could be a bit unruly. The afternoon hangs at 10 ft, but again, it’s for experts only.

So, the verdict: the first week and a half is a write-off. The only real standouts are Monday the 18th and Tuesday the 19th of August. If you’re an experienced surfer, Monday morning looks like the pick of the bunch – big, clean, and powerful. But don’t bring the longboard, and don’t bring the kids.

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.
