The third quarter moon, when half of the moon is again illuminated, occurs about a week after the full moon. This cycle repeats itself continuously.

Influence of the Moon on San Juan’s Tides

The moon’s gravitational pull has a significant influence on the tides in San Juan. The force of the moon’s gravity causes a slight bulge in the Earth’s oceans on the side facing the moon and on the opposite side. These bulges create high tides. As the Earth rotates, different parts of the planet experience high and low tides as they pass through the tidal bulges. In San Juan, there are typically two high tides and two low tides each day, with the highest tides occurring around the time of the full and new moons. The strength and timing of the tides can also be affected by other factors, such as the shape of the coastline and the depth of the water.

Humidity Levels

San Juan, Philippines experiences high humidity levels throughout the year. As a tropical region, it regularly exhibits relative humidity values above 70%, creating a humid and often uncomfortable atmosphere. During the wet season (May to October), humidity levels surge to an average of 85%, making outdoor activities more challenging. However, even during the dry season (November to April), humidity remains elevated at around 75%, contributing to the overall mugginess and discomfort.

Impact on Comfort and Health

High humidity levels can significantly impact human comfort and well-being. They inhibit the body’s natural cooling mechanisms, increasing the risk of overheating and dehydration. Prolonged exposure to high humidity can also lead to fatigue, headaches, and shortness of breath. Additionally, elevated humidity levels create a favorable environment for mold and mildew growth, posing health concerns for individuals with respiratory conditions or allergies. Residents often adapt to the humidity by using air conditioners, fans, and other cooling methods to maintain a comfortable indoor environment.

Surface Winds

In San Juan, Philippines, surface winds play a significant role in shaping the local climate. The prevailing wind direction throughout the year is northeast, bringing cool and moist air from the Pacific Ocean. These winds are predominantly strong during the summer months (May to September) and tend to weaken during the winter months (December to February). During the dry season, the surface winds are often influenced by the presence of the northeast monsoon, which brings dry and cool air to the region.

Upper-Level Winds

In the upper levels of the atmosphere, the winds in San Juan exhibit a more complex pattern. At altitudes above 1500 meters, the prevailing wind direction shifts to the west or southwest, especially during the summer months. These upper-level winds are responsible for transporting moisture and heat from the equatorial regions to the mid-latitudes. During the winter months, the upper-level winds tend to weaken, and the prevailing direction becomes more variable. The interaction between surface and upper-level winds plays a crucial role in driving atmospheric circulation patterns and contributing to the climate variability of San Juan.
