The Lowdown

Alright, let’s have a look at the next couple of weeks. It’s a bit of a slow start, but there’s some promise further down the line if you’re patient.

We’ve got a real lull right now. Porsmilin is seeing a quick pulse of 7ft swell from the WNW on Sunday afternoon, but with an 18 mph cross-off NW wind, it’s making for poor surf conditions and the combined energy is only 601 – moderate at best. That’s not worth rushing out for. Sunday’s a write-off. Then there’s a gap of bleak conditions that lasts through to about Thursday the 31st. We get a few mornings of small 3ft to 4ft surf, but it’s ordinary. By Friday afternoon, there’s a bit of a bump to 4ft (WNW, 8 sec), but the wind freshens to 15 mph, and it’s just not coming together.

Now, things actually start to look up by Monday the 5th of August. The swell builds to 5ft from the W but the wind is light cross-onshore, so it’s messy. You have to wait until Thursday the 6th of August for the first real standout. Thursday morning brings a solid 8ft WNW swell with a 10-second period and clean conditions, a gentle cross-off NW breeze. The combined wave energy is a strong 1347, so there’s plenty of push. The waves will have good shape here at this sandbar break, and the wind will keep the faces tidy. By the afternoon, it stays clean – 8ft, cross-off – but the wind picks up a little. This is the best session of the first week and a half.

Then hold onto your board. Saturday the 8th of August is the big one. That morning, we’re looking at an 12ft swell from the W with a 10-second period. The combined energy hits a whopping 2254, so there’s a serious amount of water moving. The wind is a clean cross-off from the NNW at 12 mph. This is proper groundswell energy. But I gotta be honest with you – at 12ft, this is strictly for experts. It’s too big for beginners. The crowd factor is listed as “sometimes,” so on a day like this, you might actually find some space because plenty will be put off by the size. Later that afternoon, it drops to 10ft but turns a bit messy with a cross-shore wind.

Anything after that drops off fast into smaller, wind-affected slop for the rest of the forecast window.

So the standout sessions are Thursday the 6th of August morning, and then the big show on Saturday the 8th of August morning for the experienced crew. The water temp out at Porsmilin is sitting at 65°F, which is normal for this time of year, so you won’t need a thick suit, just some good timing and a bit of nerve for that bigger day.

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.
