Wind was coming from the north at 10-15kts and skies were partly cloudy as Thursday kicked off. There were little waves at Dee Why, but it was too small for the point and the beach looked to be an inconsistent knee to maybe waist high on the biggest ones. It was clean though. According to the Bureau we can expect the swell energy, such as it is, to fade. As of 0800 it was 1.2m at 10 sec from 153° (SSE). Tide hits the 1.7m high at 0935. We’re expecting a high of 30C today (yikes) but water has at last started warming a bit and according to Beachwatch it was 20C this morning.
It’s Thursday, so make sure you check back later to see what the Mighty Goat thinks of our surf prospects for the coming week.
A little favour to ask this morning…
As most of you will know, the Council is currently building a seawall along the Collaroy Narrabeen stretch. If you’ve had a walk along there, you’ll also know that it involves the installation of vertical concrete wall as a first step. They’ll then tip boulders in front of the wall and push the sand back up over it. But the problem is that this particular design seems to have come about very late in a process that’s been going on for years to determine the best balance of public and private interests.
My take is that the wall cuts the beach width dramatically. The natural slope of the dunes goes well west of the wall, so I think, based on experiences from around the world, that this will gradually turn into a continuously exposed boulder barrier, a dramatically narrower beach that will disappear altogether with greater frequency as storm intensity relentlessly increases due to our inaction on climate change and as the sea level rises.
We will have given up the beach to protect the interests of those fortunate enough to own property on what used to be coastal dunes. In coming years the wall will likely have to be extended as the wave processes gouge out the unwalled dunes from north of the Marquesas buildings.
Surfrider Foundation Northern Beaches has posted an explainer on the subject (see below), so maybe check that out before you make your comment. Oh, and by the way, the comment form has one of those Captcha things and general experience is that it can take a few tries to get your submission to go through. I got it on my second go but others needed three or four tries.
Please find 10 minutes today to pitch in and help out with your comments. And on that, it’s important to remain polite and to mention your connection to the Collaroy-Narrabeen beach and the Northern Beaches in general. Should be easy for surfers from around here as we’ve all enjoyed the waves there at one point or another!
A high pressure system lies east of Australia. A strong southerly change is forecast to move across southern and central parts of the coast today, extending to northern parts on Friday morning. Winds will then turn northerly as a second high tracks into the Tasman, ahead of another change forecast to move through southern waters on Sunday.
Forecast for Thursday until midnight
