The Lowdown
Alright folks, Rusty here. Let’s have a look at what’s coming up for Porsmilin over the next couple of weeks.
Right off the bat, we’ve got a bit of a slow start. Sunday morning is looking weak and messy with a cross-onshore breeze and only 4ft of swell, and the energy is weak (240). Not worth paddling out for. That carries on through Sunday afternoon as well.
Monday morning, the 7th of September, is where things start to get interesting. A solid 7ft swell from the west rolls in, with a 13-second period behind it, so it’s got some proper groundswell feel. The combined energy jumps right up to 1374, which is a healthy pulse. The wind is cross-shore, but it’s clean enough to give it a crack. It’s a sandbar setup, so with that long period, the sets might be a bit shifty, but it’s the best looking window of the early week. The afternoon stays similar at 7ft, with a cross-offshore breeze, so it’ll be cleaner. This is your standout. The water temperature is about what you’d expect for this time of year, so no nasty surprises.
Tuesday the 8th drops back to 5ft in the morning, but the period shortens to 10 seconds, and the energy is moderate (510). The wind is cross-shore, and it’s a bit grotty with that light rain. The afternoon improves a bit with a cross-offshore breeze and 4ft, but it’s still marginal.
Wednesday the 9th and Thursday the 10th are pretty average. The swell hangs around 5ft to 3ft, but the wind directions are onshore or cross-onshore, making it choppy and poor. Not worth the drive.
There’s a real gap here from Friday the 11th through to the middle of the next week. Friday morning has a fresh cross-onshore wind at 30 km/h and a lumpy 5ft – that’s kite-surfing weather, not paddle surfing. The afternoon cleans up a bit, but it’s still only marginal.
Saturday the 12th has a moment of glassy conditions in the morning with a tiny 3ft, but the energy is weak (206) and it’s pretty ordinary. The afternoon picks up to 5ft with a 10-second period and moderate energy (656), but the wind goes light cross-shore, it’s just okay.
Sunday the 13th through Monday the 14th is small and clean, with offshores and cross-offshores, but the swell drops to 2ft and 2ft. The energy is very low (134-195). Not much to get excited about.
Now, looking ahead to the second week, things get more promising. Tuesday the 15th shows 4ft from the west-northwest with a 12-second period, moderate energy (425), and clean conditions. Wednesday the 16th morning is the best of the long-range call: 4ft, 12-second period, gentle offshore wind, and the forecast says “expect good surf conditions.” That’s a solid, clean, lined-up day for intermediate surfers. The afternoon gets a bit windier, but still clean.
Thursday the 17th morning also has good surf conditions with 5ft and a gentle offshore. That’s a nice little run right there. The energy stays moderate (342-353).
After that, Friday the 18th through Sunday the 20th stays in the 4ft to 4ft range, with offshore and cross-offshore winds, but the energy drops a bit and the quality is just surfable or marginal. It’s not terrible, but not the highlight.
Finally, Monday the 21st morning fades to 2ft with very weak energy (147) and a light cross-offshore. It’s clean, but tiny.
Bottom line: The real standout is Monday the 7th of September, with a solid 7ft west swell, 13-second period, and clean cross-offshore winds. That’s your best bet. Then keep an eye on Wednesday the 16th and Thursday the 17th mornings for a repeat of clean, offshore conditions with a consistent 4-5ft. The rest is mostly small, clean, or a bit messy. Stay patient.
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.
