The Lowdown

Alright folks, Rusty here. Let’s have a look at what’s cooking for the next couple of weeks.

To be straight with you, right now and for quite a while, we’re in a flat spell. The numbers are just not there. The first decent chance won’t come around until late in the month. It’s a bit of a bummer, but that’s how it goes sometimes.

Starting from Wednesday the 15th of July, it’s all tiny, weak waves. We’re talking swell heights of just 1 to 2 ft, and the combined energy is really low, barely hitting 34 (weak energy) at best. The water temp is sitting around 66°, which is a touch warmer than normal for this time of year. A few mornings will have a light offshore breeze, keeping things clean, but the waves are just too small to bother with. This flat and weak pattern will drag on through the rest of July. We’ll see a few days with stronger winds, like that strong offshore breeze on the 19th, but it’s still wind over nothing. One small pulse shows up on the 25th of July with a 2 ft swell from the west and a moderate combined energy of 42 (still moderate/weak), but the wind is cross-offshore and not ideal for the tiny size.

The real standout doesn’t even arrive until the very end of the period. On Tuesday the 28th of July and Wednesday the 29th of July, the swell period bumps up to 10-11 seconds, and the wind lightens right off. We’re talking about Porsmilin (sandbar). You’ll get a clean 1 ft swell from the WNW. On the 28th afternoon, that light NW breeze goes cross-offshore, making it glassy. The combined energy is still in the low 30s (weak), so we are not talking about any power, but for this run, that’s as good as it gets. After all that flatness, a clean 1 ft wave with no wind will be a welcome sight for the longboard or a foiler.

So, there’s your one true standout window: the 28th and 29th of July. A little promise, but keep your expectations measured. The rest of the fortnight is a write-off.

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.
