The Lowdown
Alright folks, Rusty here again, translating that for the imperial crew.
We’re looking at Porsmilin, a sandbar setup that’s fairly consistent. The water temp is about average for the time of year, so nothing freaky there. The first real chance to get wet is Saturday morning, September 5th.
Saturday morning is the standout. We’ve got a clean 7 ft swell from the WNW, with a nice long 13-second period giving it some real grunt. The combined energy is solid (1488), and with a light E breeze at 6 mph keeping it cross-off, the surf will be organized and powerful. This is excellent for experienced surfers. If you’re charging, this is your window. By Saturday afternoon, the swell drops a touch to 6 ft, still clean, but the energy dips a bit (1034). Still a very good session.
Sunday morning, September 6th, things get messy. The swell drops to 3 ft, but the wind swings SE at 12 mph, putting a cross-on chop on it. Energy is down to 201. I’d give it a miss. Sunday afternoon is worse, with onshore wind.
Monday, September 7th, we see a new pulse of 7 ft swell from the W, but the wind is problematic. Morning is cross-shore with a light breeze, keeping it marginal. The afternoon gets a moderate cross-shore chop, making it tough. Energy is high (1510 and 1290), but the quality is just not there.
From Tuesday, September 8th, through to the end of the first week, the wind stays onshore or cross-onshore, and the quality drops off. There are a few pulses of decent swell size (6 ft to 7 ft), but the wind and chop ruin it. We’ve got a long stretch of poor conditions.
The second week picks up a little. On Tuesday, September 15th, we get a 4 ft swell from the WNW with a long 14-second period and a clean cross-off wind from the NNW at 22 mph. The energy is moderate (672). The conditions are clean, but the swell is a bit weak. It’s a marginal call, but the cleanest we’ll see in a while. Wednesday, September 16th, is similar but with a shorter period.
Overall, the only real standout is the first Saturday. After that, it’s a lot of waiting for the wind to play nice.
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.
