The Lowdown

Alright folks, Rusty here. Let’s have a look at what’s cooking for Porsmilin.

Right off the bat, we’re looking at a pretty flat start. The first few days are a write-off for proper surfing. The swell is tiny, barely 1ft, with only weak energy in the water. It’s basically a lake out there for a bit. There’s a gap of about three days with no real surf to speak of.

Things start to get interesting around Sunday morning, July 26. The swell picks up to 5ft from the WNW, and the energy jumps to a moderate 279. The period is a short 7 seconds though, so it’s going to be a bit lumpy and weak. The wind is a cross-off from the NW at 15 mph, so it’s not clean enough for it to be a goer. The scores are low, and it’s described as marginal. The afternoon is similar with 6ft and 423 energy, but still not clean.

Now, here’s your standout. Monday morning, July 27. This is the best on offer. The swell is a solid 5ft from the WNW, with a period of 9 seconds. The combined energy is a moderate 404, so there’s some push behind it. What makes this special is the wind: glassy offshore from the N at just 3 mph. That’s a major positive. The description says "expect good surf conditions." This is your window. It’s not too big, so it’s still okay for intermediate crew, but with that clean offshore wind, the sandbar should be holding nice lines. The water temp is about average for the time of year, nothing unusual.

The rest of the week is a mixed bag. Monday afternoon the wind gets strong again, so it’s no good. Tuesday and Wednesday see the swell drop back to the 3ft – 3ft range with fair energy, but the wind is cross-off, keeping it clean but the waves are just ordinary. The period stays around 9 seconds, so it’s not terrible, just not the standout.

Thursday morning, July 30 is a maybe. 4ft from the NW at 8 seconds, with a light N breeze. It’s surfable but nothing to write home about.

Then we hit another flat spell. From Friday, July 31 through to Tuesday, August 4, the swell is small, the wind is onshore or cross-on, and the conditions are poor. There’s a spike of 5ft on Sunday, August 2, but the wind is a fresh cross-shore from the W at 22 mph, making it a messy, lumpy mess. That’s more of a kite-surfing session than a paddle session.

The very end of the forecast, on Friday morning, August 7, shows a return of cleaner conditions. 5ft from the WNW with a 9-second period, a light offshore from the NNE. It looks promising, but it’s a long way out, so keep an eye on it.

To sum it up: if you’re surfing Porsmilin, your best bet is Monday morning, July 27, when the stars align for a clean, waist-to-chest high session with offshores. The rest of the time, it’s a waiting game or a gamble on the long-range call.

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.
