During the summer months (October to March), the sun’s intensity is at its peak, with daily UV index readings often exceeding 10, the highest level on the scale. This extended exposure to strong ultraviolet radiation increases the risk of sunburn, skin damage, and long-term health effects such as skin cancer.

Protective Measures and Health Implications

Due to the intense solar radiation in Manaus, residents and visitors are advised to take protective measures to minimize exposure. Wearing protective clothing, hats, and sunglasses, seeking shade during peak hours, and using sunscreen with a high SPF are essential. Prolonged exposure to high UV levels can cause various health problems, including skin damage, cataracts, and weakened immune systems. It is crucial to be mindful of these risks and take precautions to protect against excessive sun exposure.

Appearance and Visibility

In Manaus, Brazil, the Moon exhibits various appearances and visibility patterns throughout the month. During the new moon phase, around the time of the lunar conjunction, the Moon is not visible in the sky. As the month progresses, the Moon gradually increases in size and visibility, culminating in the full moon phase. The full moon shines brightly and is easily visible throughout the night. Throughout the lunar cycle, the Moon’s position in the sky changes, rising in the east and setting in the west, mirroring the Sun’s movement. The Moon’s appearance is also influenced by its altitude, with higher altitudes yielding brighter and more distinct visibility.

Cultural and Folklore Significance

The Moon holds cultural and folkloric significance for the people of Manaus. Many traditional beliefs and practices are associated with the Moon’s cycles and phases. For instance, some believe that planting crops during the new moon favors growth and abundance, while harvesting during the full moon promotes preservation and longevity. Folklore surrounding the full moon includes the notion that it influences human behavior and emotions, leading to heightened senses, increased energy, and enhanced intuition. Additionally, certain lunar phases are traditionally associated with specific events, such as the harvest moon in September, marking the end of the harvest season.

Seasonal Humidity Variations

Manaus, the capital of the Brazilian state of Amazonas, experiences significant humidity fluctuations throughout the year. During the dry season, which typically lasts from June to November, relative humidity levels average around 60-70%. However, during the wet season (December to May), humidity levels soar, often reaching 90% or higher. This extreme humidity is attributed to the city’s location in the Amazon rainforest, a region prone to heavy rainfall and high evapotranspiration rates.

Impacts of High Humidity

The high humidity in Manaus can have both positive and negative impacts. On the one hand, it contributes to the city’s lush vegetation and abundant biodiversity. The rainforest ecosystem thrives in humid conditions, and many species of plants and animals are adapted to high humidity levels.
