Good Morning,

 

With the local weather conditions, this morning’s high tide peaked 21cm above predicted.

 

Predicted was 3.07m at 0734hrs

Achieved was 3.28m between 0715 – 0726hrs

 

If this continues for the rest of the week, we can expect to see similar inundation to last year with a tide in excess of 3.6m on Thursday around 0930hrs rather than the predicted 3.41m king tide for the year.

 

Cairns HAT is 3.5m, anything above this can create issues primarily along the foreshore.

 

Adding this morning’s excess height to the weeks high tides looks like this:

 

Date	Time	Predicted	With Monday’s excess height
Tue 17 Feb	0814hrs	3.27m	3.48m
Wed 18 Feb	0853hrs	3.39m	3.60m
Thu 19 Feb	0931hrs	3.41m	3.62m
Fri 20 Feb	1009hrs	3.31m	3.52m
Sat 21 Feb	1048hrs	3.10m	3.31m

 

Stronger winds, lower air pressure and/or heavy rain can further add to the heights
