The Lowdown
Alright folks, Rusty here with the lowdown for the next couple of weeks at Porsmilin.
To be honest, we’re starting out pretty slow. The first few days are a bit of a dud. Monday and Tuesday, August 10th and 11th, have tiny waves and messy wind, not worth gettin' wet for. Wednesday the 12th isn’t much better; a little more height but still ordinary conditions.
Now, Thursday the 13th of August is the one to wake up for. We’ve got a good pulse coming in the morning. The combined swell energy is a solid 277, with waves about 4ft from the West. The period is a nice 11 seconds, giving the waves some proper power, and a light cross-offshore wind from the NNW will have the faces looking glassy. The spot is a sandbar and it can get busy, but for the intermediate crowd, this is the window. It’s the standout session of the first week.
After that, it drops off again. Friday the 14th and the whole weekend look poor with building wind and dropping swell. Conditions stay ho-hum right through to the end of the next week.
Way out on the horizon, Tuesday the 25th of August has a monster showing up on the charts. We’re talkin’ a combined energy of 555, waves hitting 6ft from the WSW, and a strong offshore wind from the NE to keep it all clean. That’s a long way off, but it’s got the potential to be a classic day for the experienced surfer.
The takeaway? Thursday morning the 13th is your best bet for clean, fun waves right now. The 25th looks like a beast, but we’ll have to see how it develops. Otherwise, expect a lot of small, weak days. Might be a good time to check the kite gear.
Rusty, out.

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.

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.
