The Lowdown

Alright, Rusty here, giving you the straight talk on the next couple of weeks. It’s a rough patch, no two ways about it. We’ve got a long stretch of nothing good on the horizon.

Right now and for the next few days, it’s pretty grim. The water temp at Porsmilin is about 64°, which is average for this time of year, so you won’t freeze, but that’s the only bright spot. The combined swell energy is weak, down in the 80-130 range, with tiny waves under 3 ft. There’s a slight window on Saturday, August 22nd, with a 3 ft NW swell, 8-second period, and a light ENE cross-off breeze that’ll keep things clean. But the wave quality is poor – just barely surfable in a very average way. That’s the only hint of a wave for a long while.

From Sunday, August 23rd, right through the end of the month, it’s a dead zone. Wave heights are mostly under 2 ft, winds are either cross-off or cross-on, and it’s just not happening. The combined energy barely hits 100. It’s a total blank.

We finally see some size build up around Wednesday, August 26th, but the wind is onshore and choppy. By Thursday, August 27th, the swell jumps to 8 ft from the SW with a 9-second period, giving us a solid 843 combined energy – that’s moderate to strong. But it comes with a risk of thunderstorms and a strong cross-onshore wind. It’s lumpy and messy. Friday, August 28th, is even bigger, with 8 ft to 10 ft, WSW swell, and near-gale cross-onshore winds at 31 mph. That’s blown out, dangerous, and for experts only. That setup looks more interesting for kite surfing than paddle surfing.

The first week of September doesn’t offer much relief. There’s a small uptick in quality on Friday, September 4th, with a 5 ft WNW swell, 8-second period, and a cross-off NW breeze at 12 mph. The combined energy is 278, so moderate. It’s rated as marginal by the end of the afternoon, but it’s the cleanest we get in weeks. Still, not a standout.

Then on Saturday, September 5th, we get a big pulse: 7 ft from the WNW with a long 11-second period. The combined energy is 1116 – strong. But the wind is strong onshore from the SSW at 15 to 28 mph, so it’s a complete washout. The long period could make it break too straight at this sandbar, so it’s not the one.

Here’s the bottom line: there is no true standout in this entire 16-day window. The best of a bad bunch is probably Saturday morning, August 22nd, with clean 3 ft surf and light wind. If you’re desperate, try Friday afternoon, September 4th. Otherwise, we’re looking at a blank run. This area can go flat like this, so keep the faith – forecasts can change, but right now, it’s a long wait.

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.
