Moon Observations in Banda Aceh

Banda Aceh, the capital of Aceh province in Indonesia, offers a prime location for moon observation due to its clear skies and low light pollution. During the new moon phase, the sky becomes exceptionally dark, creating a perfect canvas for stargazing and moon observation. The moon appears as a thin crescent, its faint glow illuminating the night sky. As the moon waxes, its shape gradually transforms into a half-moon and then a full moon. During this time, the moon’s surface features become more prominent, allowing observers to witness craters, mountains, and other geological formations.

Importance of Moon Observation

Moon observation has cultural, religious, and scientific significance in Banda Aceh. The moon’s phases play a crucial role in Islamic religious practices, such as determining the start of the fasting month of Ramadan and the Eid al-Fitr celebration. In the past, the Sultanate of Aceh used moon sighting to mark important events and make decisions. Today, the moon continues to be a source of fascination and wonder for both locals and tourists, inspiring artists and photographers to capture its ethereal beauty.

Relative Humidity Patterns

Banda Aceh experiences high relative humidity throughout the year, with an average annual value of approximately 80%. This high humidity level is influenced by the city’s tropical monsoon climate, characterized by heavy rainfall and warm temperatures. During the wet season, which spans from October to April, humidity levels soar to their peak, often reaching 90% or higher. This high humidity, combined with the warm temperatures, can create an oppressive and uncomfortable environment.

Impacts of High Humidity

The high humidity in Banda Aceh has several significant impacts on daily life and the environment. Excessive humidity can exacerbate respiratory issues, such as asthma and allergies, due to the increased moisture in the air. It can also make outdoor activities uncomfortable, especially during the hottest hours of the day. Additionally, high humidity can contribute to the growth of mold and mildew, leading to potential health hazards and damage to buildings and infrastructure.

Wind Patterns and Seasonality

Banda Aceh, located on the northwestern coast of Sumatra, Indonesia, experiences distinct wind patterns influenced by its geographical location and the prevailing monsoon winds.
