Tropic of Cancer is at 23.5 Degrees North.
Havana is not exactly on it...But slightly south.
But still at 12:00 Noon the sun is near the zenith.
the shadows cast will not be at an angle to
the objects.

Actually solstice can occur at Summer and at winter relative to Northern Hemisphere.

Since havana is in Northern Hemisphere and it's Tropic of cancer and Not the Tropic of Capricorn...Parksie
is wrong...But He was the first one to be closer to the
answer.
