The Lowdown
Alright folks, Rusty here. We’re looking at a pretty grim stretch ahead for Porsmilin. There’s no good surf on offer in this whole 16-day window, and we’re starting right into it with flat, poor conditions. The first week is a write-off. We’ve got a long gap of over a week before we even see any size, and when it comes, the conditions are still ugly.
The water temp is about average for the time of year at 65°F, nothing special there.
Tuesday the 11th is tiny with weak 2ft WNW swell and hardly any energy (56). The wind is okay in the morning but the surf is nonexistent. Wednesday and Thursday see a little bump, with the best of the weak period on Thursday the 13th morning – a 4ft W swell with 11 seconds of period and moderate energy (279), and cross-off NW winds. It’s clean, but the guidance calls it marginal, and honestly, it’s just not worth getting wet for. Crowds are sometimes a problem here, but not when it’s this average.
Saturday the 15th morning has a stiff 16 mph offshore wind from the north, but the swell is a weak 3ft from the WNW with a short 8-second period. The energy is only 140. Barely surfable.
We then hit a real blank patch. From Sunday the 16th right through to Friday the 21st, it’s all under 3ft or just ordinary. The only slight glimmer is on Wednesday the 19th morning when it’s glassy with a 4ft WNW swell (160 energy), but the period is short and the conditions are still just "surfable but very ordinary."
Now, for the second week, there’s size but no quality. On Sunday the 23rd, a 8ft WSW swell (724 energy) rolls in, but it’s onshore with a fresh SW wind. That’s getting too big for beginners, and the chop will be a mess. Monday the 24th sees the biggest swell of the period – an 8ft WNW groundswell with a 10-second period and massive energy (2260). But the wind is howling from the W at 22 mph, creating a strong cross-shore chop. At this size and with that wind, this is more of a kite-surfing show than a paddle session. Over 8ft and messy like that is for experts only, and even then, it won’t be pretty.
So the bottom line: nothing stands out. The setup looks more interesting for kite surfing than paddle surfing on the big days around the 23rd and 24th of August. For a regular surfer, it’s a long, frustrating wait.
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.
