The Lowdown

Alright folks, Rusty here. Let's have a look at what Porsmilin has in store for us over the next couple of weeks.

The outlook is a bit of a mixed bag. We’ve got a long stretch of pretty ordinary, small surf to start, but there are some bigger, more promising pulses showing up for the second week. Hang in there, because the end of the run looks like it could be the real deal.

First up, the opening weekend is a no-go. Saturday the 8th offers a tiny 2ft NW windswell at a short 10 seconds, but it’s cross-shore and messy. Sunday the 9th is clean, but still only 2ft and the energy is weak (combined energy of 93-96). Monday the 10th and Tuesday the 11th are nothing to write home about either, with waves barely scraping 2ft and periods dropping as low as 8 seconds.

Things slowly build through the middle of the week. Wednesday the 12th sees a small rise to 3ft-3ft from the west, but it’s onshore or cross, and the energy is still low (131-143). Thursday the 13th morning is the first one that gets my attention. We’ve got 4ft from the west with an 11-second period, which gives a moderate kick of energy (338). The wind is a clean cross-offshore from the NW. That’s a good chance for some fun, shapely waves on the sandbar. The afternoon gets a bit too blowy though.

After that, we drop right back into a slump. From Friday the 14th all the way through to Friday the 21st, the swell is puny – mostly 2ft to 3ft. The periods are short and the energy is weak (as low as 37). It’s a long, flat spell that you’d be better off skipping.

Then it changes. The real story starts on Saturday the 22nd of August. A solid pulse of swell arrives, ramping up to 6ft from the west by the morning, hitting 7ft from the WNW in the afternoon. The combined energy jumps to 483 and then a strong 714. However – and it’s a big however – the wind is a fresh cross-shore (15-19 mph) from the WNW, which is going to chop it up. This is more of a kite-surfing setup than a clean paddle session.

The standout window, and what looks like the best on offer, is Sunday the 23rd of August. You’re looking at a solid 10ft of WNW swell with a 10-second period. The combined energy is massive – 1830 in the morning, 1735 in the afternoon – that’s very strong wave energy. The wind is a clean cross-offshore from the NNW, blowing at 15-19 mph. That’s going to hold the faces open. At 10ft, this is definitely expert territory, so only the experienced crew should be paddling out. This is a long-range promise, so keep an eye on it as the date gets closer. For a sandbar setup, a long-period groundswell like this can sometimes be a bit straight, but the offshore wind should help it peel.

Water temp is sitting at a pretty average 65°F for this time of year, nothing unusual there.

So to wrap it up: the first two weeks are mostly a write-off of small, weak waves. Thursday the 13th morning is your best early bet for a clean, fun session. But the real spitfire is Sunday the 23rd – a big, powerful, offshore day that’s got serious potential for the experts.

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.
