The Lowdown

Alright, Rusty here, let’s break it down for Porsmilin in feet and miles per hour. A real mixed forecast, but there’s some gold in there for those who wait.

We kick off Tuesday with a 8ft swell from the west, but that wind is howling at 31 mph from the NNW, making it a complete mess. The energy is substantial (783), but don’t bother paddling out – it’s just blown out. The afternoon drops to 6ft, still a stiff cross-offshore breeze, but the quality is marginal. Water temp is about 64°, pretty normal for September.

Wednesday is still a no-go, with similar winds and smaller swell (5ft then 5ft from the NW). Energy is moderate (588, 473). Thursday is tiny and onshore – skip it.

Friday brings a little hope: 5ft from the west, with cleaner cross-off winds at 12 mph. It’s surfable, not a standout. But then Saturday morning, September 12th, we get a gem. The wind goes glassy – dead calm – and the swell is a nice 4ft from the WNW. Energy is moderate (475), but that glass makes it a treat for an intermediate. Crowds can show up, so go early. The afternoon pumps up to 6ft with a long 13-second period and strong energy (1058), but the wind swings cross-shore, so it won’t be as clean.

Sunday the 13th is the same 6ft swell but cross-onshore and choppy. Monday and Tuesday drop to small, weak surf (2ft to 4ft) with poor wind. A few days off.

Now, Thursday the 17th of September – this is the one. Morning brings a 7ft WNW swell (758 energy) with a clean offshore breeze from the NNE at 12 mph. That’s a proper session for the sandbar. The 9-second period gives good push, and the offshore wind will groom it nicely. This is for intermediates and up, as 7ft is too big for beginners. The afternoon is still clean with 6ft and offshore winds, but the period drops, so morning wins.

After that, Friday the 18th is ordinary, but Saturday the 19th shows a 5ft WNW swell with clean cross-off winds and a long 13-second period in the afternoon (693 energy) – a solid weekend wave.

The 21st looks wild on paper: 8ft from the WNW with a very long 17-second period and massive energy (3119). But the wind is a near-gale 31 mph, so it’s dangerous for paddling – leave it to the kite surfers. The following days drop to 3ft to 6ft, clean but unexciting.

Bottom line: Saturday morning the 12th for glassy fun and Thursday morning the 17th for the real power. There’s a flat spell in the middle, but stuff changes. Keep your eyes peeled.

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.
