The snowfall lasted for several hours, covering the city in a thin layer of white.

Impacts of the Snowfall

While the snowfall in Accra was a beautiful and unusual sight, it also had some negative impacts. The snow caused power outages and disrupted transportation in the city. Schools and businesses were closed as the snow made it dangerous to travel. The unexpected snowfall also highlighted the challenges of climate change and the need for adaptation measures in regions that are not typically accustomed to such extreme weather events.

Sun’s Position and Movement in Accra

Accra, the capital of Ghana, is located in the southern part of the country, close to the Equator. As a result, the sun’s position and movement in Accra are influenced by its proximity to the Equator and the Earth’s axial tilt. Throughout the year, the sun rises and sets almost directly east and west, with only slight variations due to the Earth’s elliptical orbit around the sun. The sun is at its highest point in the sky at noon, and its altitude varies only slightly throughout the year.

Duration of Daylight and Seasonal Variations

The duration of daylight in Accra varies slightly throughout the year due to the Earth’s axial tilt. During the Northern Hemisphere’s summer, from May to August, Accra experiences longer days with sunrise occurring around 5:30 AM and sunset around 6:30 PM. During the Northern Hemisphere’s winter, from November to February, the days are slightly shorter with sunrise occurring around 6:30 AM and sunset around 5:30 PM. The total amount of daylight varies by approximately 1 hour between the longest and shortest days of the year.

Moon Phases in Accra, Ghana

The Moon’s phases as seen from Accra, Ghana, follow the same general pattern as observed from most locations on Earth. The Moon’s appearance changes throughout the month due to its changing position relative to the Earth and Sun. During the new moon phase, the Moon is invisible as it lies between the Earth and the Sun. As the Moon orbits the Earth, its illuminated portion gradually becomes visible, leading to the waxing crescent and first quarter phases.

Waxing and Waning Phases

The full moon phase occurs when the Moon is opposite the Sun in the sky, resulting in its entire face being illuminated. After the full moon, the Moon’s illuminated portion starts to decrease, leading to the waning gibbous, last quarter, and waning crescent phases. The cycle then repeats itself, with the new moon phase marking the start of a new lunar month. The duration of a complete lunar cycle, from new moon to new moon, is approximately 29.5 days.

Humidity in Accra, Ghana

Accra, the capital city of Ghana, experiences high humidity throughout the year, with average relative humidity levels ranging from 70% to 90%. This humidity is primarily due to its proximity to the Gulf of Guinea, which provides a constant source of moisture in the atmosphere. Additionally, the city’s tropical climate contributes to the high humidity levels, with temperatures often exceeding 30 degrees Celsius.

The high humidity in Accra can have various effects on the city’s residents and visitors. It can cause discomfort, especially during the hot and humid months from April to October. The high moisture content in the air can make it difficult to regulate body temperature, leading to excessive sweating and heat exhaustion. Prolonged exposure to high humidity can also contribute to respiratory problems and skin irritation.

Despite the challenges it poses, the high humidity in Accra also has some positive effects. It helps to maintain lush vegetation and supports the city’s thriving agricultural sector. The humidity also helps to moderate temperatures, preventing extreme heat waves and ensuring a relatively stable climate throughout the year.

Climate and Wind Patterns

Accra, Ghana’s capital city, experiences a tropical savanna climate, characterized by alternating wet and dry seasons.
