In Port-au-Prince, Haiti, the sun rises and sets relatively consistently throughout the year due to its proximity to the equator. The sunrise typically occurs between 6:00 AM and 6:30 AM, and the sunset generally happens between 6:00 PM and 6:30 PM local time. These times may vary slightly during the summer and winter solstices.

Daylight Hours

Port-au-Prince experiences an average of 12 hours of daylight per day, with minimal seasonal variations. The longest day occurs around the summer solstice in June, when the sun shines for approximately 13 hours. Conversely, the shortest day happens during the winter solstice in December, when daylight lasts about 11 hours. This consistency in daylight hours is beneficial for outdoor activities and tourism throughout the year.

Location and Visibility

Port-au-Prince, the capital of Haiti, is situated in a tropical region, and the moon’s visibility varies throughout the month. During the new moon phase, the moon is not visible, as it aligns between the Sun and Earth. As the moon progresses through its phases, it becomes increasingly visible, reaching its peak brightness during the full moon. In Port-au-Prince, the full moon is known as “plen lalin” or “plenty moon,” and it illuminates the night sky with its ethereal glow, casting long, dramatic shadows across the city’s vibrant streets and bustling markets.

Cultural and Astronomical Significance

The moon holds great cultural significance in Haitian society, and its phases are often associated with specific events or superstitions. For example, the new moon is believed to be a time of introspection and renewal, while the full moon is often associated with heightened emotions and increased activity. In Haitian Vodou, the moon is considered a sacred element, and it is often depicted as a symbol of fertility and guidance. Astronomically, the moon’s gravitational pull significantly influences the tides of the Caribbean Sea, which surrounds Port-au-Prince. The moon’s orbit also affects the Earth’s axis, creating the illusion of the moon rising and setting at different times throughout the year.

Seasonal Humidity Patterns

Port-au-Prince’s humidity levels vary throughout the year, primarily influenced by the tropical monsoon climate. The wet season, which runs from April to November, brings higher humidity due to increased rainfall. During this time, average humidity ranges from 65% to 95%, reaching its peak around 80%. The dry season, from December to March, is characterized by lower humidity. Average humidity during these months falls between 40% and 70%, with average values around 60%.

Diurnal Humidity Variations

Furthermore, diurnal humidity variations occur within each day. During the early morning hours, humidity tends to be higher due to the condensation and fog formation that occurs as temperatures cool down. As the day progresses, temperatures rise, causing the humidity to decrease. The lowest humidity levels typically occur during the afternoon, following the peak of the day’s temperature. As the sun sets, temperatures begin to drop again, leading to an increase in humidity toward the evening and night.

Wind Patterns in Port-au-Prince, Haiti

Port-au-Prince, situated on the southern coast of Haiti, experiences distinct seasonal wind patterns. During the winter months from November to April, the northeast trade winds dominate, bringing cool and dry air from the Atlantic Ocean.
