The Lowdown

G’day, Rusty here. Look, I’ll be straight with you – for the next week or so, Porsmilin is in a bit of a slump. There’s just not enough quality to get excited about. The swell is there, sometimes, but it's small, short-period stuff, and the wind doesn’t often play ball. We’ve got a long gap of ordinary days ahead before things finally start to look up.

Let’s start with Thursday the 6th. The morning offers a little 3ft swell from the WNW, but it’s a weak 6-second period and the wind is a cross-off. The combined energy is only 109, so it’s pretty weak. It’s surfable, but honestly, it’s very ordinary. By the afternoon, the wind picks up to 25 km/h from the NNW, and it’s just poor.

Friday the 7th and Saturday the 8th are write-offs. Swell drops to 1.0ft and 1ft, with short periods, and the wind is either offshore or cross-off, but the waves just aren’t there. It’s frustrating.

Sunday the 9th through to Tuesday the 11th are similar – small, weak swell, mostly 2ft, with periods around 8 or 9 seconds, and the energy stays low. Wind is mostly offshore or cross-off, but it’s not enough to make it worthwhile. The water temp is sitting at 64°, which is about average for this time of year, so no surprises there.

Wednesday the 12th sees a slight bump with 3ft from the W, period up to 10 seconds, and the energy climbs to 157. Still just ordinary. The pattern continues through Thursday the 13th and Friday the 14th, with the wind turning cross-on and making things choppy and messy.

Saturday the 15th and Sunday the 16th are still poor. The swell gets a bit bigger on Sunday, hitting 5ft from the WNW, but it’s a short 8-second period with a cross-on wind, so it’s not going to be clean. The energy is 246, showing some push, but the wind ruins it.

Monday the 17th and Tuesday the 18th bring more of the same – onshore and cross-shore winds, chop, and nothing you’d want to paddle out into. The swell is up to 4ft to 5ft, but the quality is missing.

Wednesday the 19th is a write-off with a strong onshore wind, and Thursday the 20th is messy with 6ft swell from the WNW but a strong cross-on wind. The energy is 728, which is strong, but for a beach break, that’s more of a kite-surfing situation than a good paddle session.

Now, here’s the one that gets my heart pumping. Look to the morning of Friday the 21st of August. That’s the standout. Porsmilin is expecting a 6ft swell from the WNW, period of 9 seconds, and the wind goes glassy – a light 5 km/h from the NNW, with the “glass” state. That’ll be clean, smooth, and the energy is 561, so there’s proper power behind it. The water temp is still average, but the conditions will be a dream. This is a morning to make a plan for. The wind is perfect, the swell has some size but isn’t too big for intermediates, and the wave shape will be much better than anything we’ve seen. The afternoon still looks decent with a 5ft, but the wind picks up to a cross-off, so the morning is the winner.

So, overall, it’s a long wait, but that Friday the 21st morning is the real deal. Don’t sleep on it.

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.
