I would guess that Hong Kong is closer to the equator, compared to some other place where you lived, and with which you are comparing it.
Of course that question must mean "overhead around noon".
Hong Kong is more or less on the Tropic of Cancer.
The Sun can appear overhead as far north as the Tropic of Cancer around the summer solstice (about June 21st).
The sun can never be directly overhead anywhere in New York state ... or anywhere in the USA for that matter. The highest it can ever appear is at noon on June 21. But in order to ever see it directly overhead, you have to be located within 23.5 degrees of the equator.
Tropic of Capricorn
The sun appears directly overhead in Mexico City twice a year during the summer solstice and winter solstice. This occurs when the sun's rays are perpendicular to the Tropic of Cancer, where Mexico City is located.
No, the celestial equator does not always pass directly overhead. The position of the celestial equator in the sky is determined by the observer's latitude on Earth. If the observer is located at the equator, the celestial equator will pass directly overhead. However, for observers at different latitudes, the celestial equator will appear at an angle to the horizon.
The position of the sun in the sky directly affects the length and direction of our shadows. When the sun is low on the horizon, such as during sunrise or sunset, shadows are longer and stretch away from the light source. Conversely, when the sun is directly overhead, around noon, shadows are shorter and may even appear directly beneath us. As the sun moves throughout the day, the angle of light changes, causing shadows to shift in both length and orientation.
Yes. Lagos is only about 6.5 degrees from the equator ... less than the 23.5 degrees on the Tropics of Cancer and Capricorn, the boundaries of the 'belt' around the Earth's middle throughout which the sun can be directly overhead.
The Tropic of Cancer ... roughly 23.5 degrees north ... is the most northerly latitude where the sun can ever appear directly overhead.
The sun can never be directly overhead anywhere in New York state ... or anywhere in the USA for that matter. The highest it can ever appear is at noon on June 21. But in order to ever see it directly overhead, you have to be located within 23.5 degrees of the equator.
Tropic of Capricorn
That lies on 23.5 degree latitude, at which the Sun may appear directly overhead at its zenith.
No, the sun will appear directly overhead along the Tropic of Capricorn in the Southern Hemisphere.
The position and length of shadows change throughout the day due to the angle of the sun in the sky. Shadows are longest and most defined closer to sunrise and sunset, when the sun is lower in the sky. At midday when the sun is directly overhead, shadows are shortest and may appear directly below the object casting them.
The sun appears directly overhead in Mexico City twice a year during the summer solstice and winter solstice. This occurs when the sun's rays are perpendicular to the Tropic of Cancer, where Mexico City is located.
Your location must be located on the Earth's axis, specifically at the North or South Pole. At these locations, the stars appear to move in circles around the celestial pole that is directly overhead.
Never. The only time the sun can appear directly overhead at Lagos is sometime near April 5 and again sometime near September 4.
No, the celestial equator does not always pass directly overhead. The position of the celestial equator in the sky is determined by the observer's latitude on Earth.

Twice; both during the sun's summer and winter solstices.
