The Lowdown
Alright folks, Rusty here. Let’s take a good, hard look at what the next couple of weeks are serving up for Porsmilin. Gotta be straight with you – it’s a slow start. We’re looking at a real dry spell for the first several days. From Monday afternoon the 20th right through to the morning of Sunday the 26th, it’s pretty much flat or trash. Tiny little ankle-snappers around 0.7ft to 1ft with weak energy (as low as 6 to 44 in the combined energy number) and a mix of clean but gutless conditions. Not worth putting the board in the car. You’re better off doing something else.
Then, things finally start to change on Sunday the 26th. The morning shows a pulse of 4ft from the WNW, but the period is a short, snappy 7 seconds, and the energy is moderate (262). It’s still showing as "poor surf conditions" so don’t get too excited. The afternoon bumps up a bit to 6ft and a better 9-second period, pushing the energy up to 486, but it’s still a bit messy with a fresh cross-offshore wind. Still not the one.
Monday the 27th is where we get our first real nod. The morning session brings 5ft of WNW swell, period stretching to 9 seconds, and energy hitting 354. The wind is a gentle breeze from the north, cross-offshore, keeping the surface clean. This is "expect good surf conditions" territory. It’s a solid intermediate wave, but that 5ft is getting close to the line where beginners might find it a handful. Still, the clean conditions make it a decent option.
The run from Tuesday the 28th through Wednesday the 30th is a bit of a mixed bag of "ordinary" and "marginal" with some funky short-period energy. You’ll get waves, but nothing to call home about. The wind stays mostly offshore or cross-off, so the surface will be clean, but the swell quality is just okay.
Now, the real standout on the whole forecast is Friday the 31st of July. This is the one. The morning kicks off with 7ft of WNW swell, an 8-second period, and a massive energy reading of 627. The wind? It’s glassy. A slight air from the NE, dead calm. That’s a major positive. By the afternoon, it gets even better: 8ft from the WNW, a 9-second period, and energy jumping to 926. The wind stays glassy from the WNW. This is "expect very good surf conditions." Listen, this is a big swell. Over 8ft pushes it into expert territory, so if you’re not comfortable in strong, powerful waves, sit this one out. But for the crew who can handle it, Porsmilin is going to be absolutely firing and clean. Keep in mind, this spot is a sandbar, so it can handle that period, but it’s going to be a heavy, powerful wave. The crowds are listed as "sometimes," so you might have some company, but with that size, it’ll thin out the pack.
The water temperature is sitting around 64°F, which is pretty normal for this time of year, so no need for a thick wetsuit just yet.
After that Friday peak, Saturday the 1st of August gets messy with onshore winds and choppy conditions, dropping from 8ft to 6ft. The energy is still high (986 and 507), but the quality is gone. Sunday the 2nd and Monday the 3rd are more of the same, onshore mush. Tuesday the 4th of August shows a final pulse of 7ft to 7ft from the WNW, with cross-shore winds and decent energy (865 and 833), but it’s labelled as "marginal" due to the cross-shore wind and questionable tide conditions.
So, the long and short of it: suffer through the first week, maybe get a fun but not epic session on Monday the 27th, and then absolutely circle Friday the 31st of July. That’s your target. It’s a long way out, so keep an eye on it, but it’s looking promising.
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.
