The Lowdown

Right then, let’s see what’s on offer for Porsmilin. It’s a sandbar setup, intermediate territory, and it takes a fair bit of swell from the SW. Just a heads up, the water temp is sitting at 65°F with a tiny anomaly of 2°F, so that’s pretty average for the time of year; nothing wild there.

Honestly, the first week is a tough one. We’re looking at a big ol’ gap from now until the 26th of July with nothing worth paddling out for. The swell is tiny, mostly 0.7ft to 1ft, and the wind is either cross-off or offshore, but with no energy behind it, it’s just a flat, clean lake. The combined energy is barely a whisper, with values like 18 or 21 (weak energy). You’d be better off cleaning the wax off your board.

Then on the 26th of July, things finally wake up. We get a spike in swell – 6ft from the WNW, but the wind is a cross-on from the WSW, making it lumpy and choppy. The combined energy jumps to 476 (moderate wave energy), but it’s a messy, cross-on swell. It’s not pretty, and the 8-second period is short, meaning it’ll be fat and weak. This continues through the 27th and 28th with similar cross-onshore and cross-shore winds. It’s more of a kite-surfing setup than a paddling one.

The standout window finally arrives on the morning of the 30th of July. The swell is a solid 5ft from the NW, with a 9-second period, and the wind is glassy – a Slight Air at 3 mph. That’s the magic word: glassy. The combined energy is 380 (moderate wave energy), so there’s a bit of push. This is your best bet. The morning of the 30th is the pick of the entire forecast. The NW swell is a good direction for Porsmilin, and with no wind, it’ll be clean. It’s a bit of a wait, but that’s the one to circle.

After that, the 31st of July has a 6ft swell from the NW with a 10-second period, and a strong offshore NNE wind at 19 mph in the morning. The energy is high at 580 (moderate to strong wave energy), but the wind is so strong (25 mph in the afternoon) it’ll be hard to paddle into and likely a bit blown out. It’s a powerful option for experts only, as the size is over 5ft and the wind is fierce.

The first week is a write-off, but the 30th of July morning is a genuine standout. Expect crowds to be possible, as it’s the only decent day in a long stretch.

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.
