Additionally, sunglasses that block UV rays should be worn to protect the eyes.
Visibility and Phases of the Moon in Riyadh, Saudi Arabia
Riyadh, the capital of Saudi Arabia, is situated in a desert region characterized by clear skies and low humidity, making it an ideal location for moon observation. The visibility of the moon varies throughout the lunar cycle, with the full moon appearing as a bright, circular orb in the night sky. During the new moon phase, the moon is not visible from Earth as it is positioned between the sun and the Earth. As the moon waxes, it gradually increases in size and brightness until it reaches the full moon phase.
Cultural Significance of the Moon in Riyadh
The moon holds significant cultural and religious importance in Saudi Arabia. The Islamic calendar, which is used in the country, is a lunar calendar, with months beginning on the day of the new moon. The sighting of the new moon marks the beginning of each month and is widely celebrated. The moon also plays a role in determining the timing of religious observances, such as the start and end of the fasting month of Ramadan. Furthermore, the moon is often depicted in traditional Saudi Arabian art and literature, symbolizing beauty, guidance, and hope.
Humidity Patterns
Riyadh’s humidity levels vary significantly throughout the year. During the scorching summer months, from May to September, humidity typically remains low, often falling below 15%. The extremely dry conditions are a result of the low precipitation and high temperatures that characterize the Arabian Peninsula’s desert climate. As the cooler months approach, humidity gradually increases, peaking in December and January when it can reach up to 60%. The higher humidity during winter is attributed to the influence of occasional cold fronts and the presence of the Persian Gulf, which provides a source of moisture.
