Seasonal Variations of Sunshine

Port Harcourt experiences marked seasonal variations in sunshine. During the wet seasons (April-October), cloud cover is prevalent, resulting in reduced sunshine hours. The peak of the wet season (June-August) typically receives the lowest amount of sunshine, with an average of 4-5 hours per day. However, during the dry seasons (November-March), skies are clearer and sunshine hours increase significantly. The peak of the dry season (December-February) typically receives the highest amount of sunshine, with an average of 8-9 hours per day.

Factors Influencing Sunshine

The seasonal variations in sunshine in Port Harcourt are primarily influenced by the Intertropical Convergence Zone (ITCZ). During the wet seasons, the ITCZ shifts northward, bringing moist air and rainfall to the region. This increased cloud cover reduces the amount of sunshine. Conversely, during the dry seasons, the ITCZ shifts southward, allowing drier air and clearer skies to prevail. Additionally, the presence of the Harmattan winds during the dry season contributes to increased sunshine by carrying dust and aerosols that scatter incoming solar radiation.

Lunar Visibility

In Port Harcourt, Nigeria, the visibility and appearance of the Moon vary throughout the lunar cycle. During the full moon phase, the Moon rises at sunset and remains visible for the entire night. It appears as a bright, circular disk, casting its soft glow upon the city. As the Moon enters the waning crescent phase, it becomes less visible and appears as a thin sliver in the western sky.

Moon’s Influence on Tides

The gravitational pull of the Moon has a significant impact on the tides in Port Harcourt. The Moon’s gravitational force draws water towards it, resulting in high tide. Conversely, when the Moon is on the opposite side of the Earth, it exerts a weaker gravitational pull, leading to low tide. These tidal variations affect the daily lives of coastal communities in Port Harcourt, influencing fishing activities, boat traffic, and the accessibility of certain areas.

Seasonal Variations in Humidity

Port Harcourt experiences significant seasonal variations in humidity. During the wet season, which typically spans May to October, humidity levels are consistently high, averaging around 85%. The city receives ample rainfall during this period, resulting in a humid and oppressive atmosphere. In contrast, during the dry season, which lasts from November to April, humidity levels drop considerably, averaging around 65%. The Harmattan wind, which originates from the Sahara Desert, brings dry and dusty conditions to the city, leading to lower humidity levels.

Factors Influencing Humidity

Several factors influence humidity levels in Port Harcourt. The city’s proximity to the Atlantic Ocean plays a crucial role. The warm ocean currents and prevailing winds carry moisture-laden air inland, contributing to high humidity levels. Additionally, the abundance of rivers and creeks in the surrounding area further increases humidity. Local vegetation also plays a significant role, as plants release water vapor during photosynthesis, raising humidity levels in the atmosphere.
