Partly depends on where you are. Southwestern states that have a border with Mexico tend to have more native Spanish speakers (not just immigrants, but also Chicano folks who were on the land before the US took it), so even the native English speakers tend to pick up a little Spanish.

In order for the tides to rise significantly in the Baltic or Mediterranean, you’d need that much extra water to flow through the narrow opening in the straits of Gibraltar/Denmark.

The Baltic sea also probably is less affected because it’s so far north, and the tides are based on the Moon’s (not-quite-equatorial, but not THAT inclined) orbit.
