King Tide

This morning, I took the kids to the waterfront to observe a Natural Wonder.

King tides are a natural event which happen twice a year – once in summer and once in winter.  In addition each month there are spring tides which are higher than normal high tides and coincide with the full and new moon.

Today was the day of the highest king tide in 18.6 years and scientists have suggested that it will give us an idea of what coastlines may look like in 50 years in a changing climate.

It was certainly the highest tide I’ve seen in a long time given that the swell was relatively calm and so the water wasn’t crashing over the sea wall.  Rather, the kids had fun splashing in the water that was gently washing over the  wall.

I was also impressed to see someone pull up alongside the sea wall (about 1.2-1.5 m high that stretches the length of our suburb’s foreshore) in a tinny and take passengers directly off the foreshore.

The local public boat ramp was almost completely submerged (the wall the people are standing on is about 1.5 m high, and the people in the background are standing on a submerged rock groyne).

Many of the storm water drains along the foreshore are lower in elevation than the sea wall and so sea water had backed up and pools of sea water stretched across the esplanade in a few places.

    How interesting – I wonder what the king tides will look like in twenty years time? I guess our equivalent in Lismore was the regular floods – it was a weird time of devastation but also a lot of friendly socialising with people outside of the usual social circles. I don’t know where I’m going with this… cool pics…

    I was wondering a similar thing … I mean if they think this is what the “normal” sea level will be in 50 years time, then how much higher will a king tide be?
    But then I remember stories my Dad tells where the tide once was so high it flooded the cinema that used to be on the esplanade. True to form, they kept operating, but there were a few stranded mullet jumping around in the puddle at the front.

    OMG, what a cool story..

    Greta – my Dad often comes out with some insane story from when he was younger. Mostly fishing stories where large sea creatures (ie sharks) have swum alongside his boat, or seeing ball lightening when fishing on the beach.

    Mel – thanks!

    Kelley – it is sobering. But I’ve heard worse predictions from time to time – up to 97 m – that would be catastrophic.

  6. Wonderful and scarily sobering all at the same time.
