Causes of Snowfall in Longonjo, Angola
Although uncommon, snowfall has been recorded in the mountainous region of Longonjo, Angola, located at an altitude of over 2,000 meters above sea level. The occurrence of snow in this equatorial region is attributed to several factors. Firstly, the high altitude of the region lowers temperatures, creating conditions conducive to snow formation.

Additionally, the presence of moisture from the Congo Basin, carried by easterly winds, provides the necessary precipitation for snowfall.
Impacts of Snowfall in Longonjo, Angola
The infrequent snowfall in Longonjo brings both unique challenges and opportunities for the local community. While the snow-covered landscape offers a picturesque scene, it can disrupt daily life and infrastructure. Road closures due to snow and ice make it difficult for residents to conduct their daily activities and access essential services. Additionally, the cold temperatures pose health risks, especially for the elderly and vulnerable populations. However, the snowfall also brings tourism revenue to the region, as visitors seek to experience the unusual spectacle of snow in this part of Africa. Local businesses can benefit from this influx of travelers, but careful management is required to minimize environmental impacts and ensure sustainable tourism practices.

After the full moon, the moon’s illumination decreases as it wanes, eventually becoming a thin crescent again.
Lunar Phases and Cultural Significance
The lunar cycle is an important cultural reference point in Angola. Many traditional Angolan festivals and rituals are tied to specific lunar phases. For instance, the harvest festival of ‘Mwana Pwo’ is celebrated during the new moon, while the ‘Kinguila’ festival takes place during the full moon. These festivals involve traditional music, dance, and rituals that pay homage to the moon’s influence on the natural cycle of life and the seasons.
Seasonal Humidity Variations
Longonjo, Angola experiences distinct seasonal variations in humidity. During the dry season, which typically runs from May to September, humidity levels tend to be relatively low. The average relative humidity during this period hovers around 40-50%. This dryness is primarily attributed to the influence of the cool, dry Benguela Current, which flows along the coast of Angola.
In contrast, during the rainy season, which spans from October to April, Longonjo experiences significantly higher humidity. The average relative humidity during this time frame can reach up to 80-90%. The influx of moisture-laden air from the Atlantic Ocean, coupled with frequent rainfall, contributes to these elevated humidity levels.
Impact on Local Climate and Health
The varying humidity levels in Longonjo have a notable impact on the local climate and human health. During the dry season, the low humidity can lead to dry skin and respiratory ailments, while the higher humidity during the rainy season can create a more humid and uncomfortable environment.
