What influences the tides in Croatia? - 14 April 2023

Skip if you are allergic to mathematics :-)

In the previous post, I presented the tide chart for Rovinj for the 17 days starting from 17 April as shown on previous post.

 

In an attempt to better understand the interactions that result in such an interesting mixed tidal pattern (semi-diurnal and diurnal periods alternating), I digitized the 17 day series in Excel so as to study it further...

Tides and currents in the Adriatic sea - 9 April 2023

Continuing our preparation for sailing in the Adriatic, let's look at the tides and currents there.

In my sailing experience, the tides can be summarised as either huge amplitude in the Atlantic and the English Channel, particularly around the Bay of Mont Saint-Michel where the tidal amplitude can reach 12 metres, or no tide at all in the Baltic due to the very shallow and narrow opening to the northern sea!

What about the Adriatic?
