Seasonal Humidity Patterns

Bauang, Philippines experiences distinct wet and dry seasons throughout the year. The wettest period runs from June to October, coinciding with the peak of the southwest monsoon. During these months, relative humidity levels soar to an average of 85-90%. The atmosphere becomes thick, humid, and oppressive, leading to discomfort and health concerns. In contrast, the dry season, from November to April, brings significantly lower humidity levels, typically averaging 70-75%. The northeast trade winds dominate this period, bringing less moisture to the region.

Variation with Elevation

In Bauang, humidity levels also vary with elevation. As one ascends the surrounding mountains, the air becomes cooler and holds less moisture. At higher elevations, humidity levels can drop by several percentage points compared to the lower-lying areas. This difference is attributed to the cooling effect of altitude, which reduces the capacity of the air to hold water vapor. Thus, while coastal regions may experience high humidity levels, mountainous areas offer a more comfortable and less humid environment.

Wind Speed and Variability

Bauang, Philippines experiences consistent wind speeds throughout the year, with the average speed ranging between 8 to 12 knots (4-6 m/s). The wind direction is predominantly from the northeast, indicating the influence of the trade winds. However, during the summer months (May to October), the prevailing wind direction shifts to the southwest, bringing warm and moist air from the Indian Ocean. This variability in wind direction often results in stronger winds during the summer season.

Seasonal Variations

The wind patterns in Bauang are influenced by seasonal changes. During the northeast monsoon season (October to April), the winds are stronger and more consistent, reaching up to 14 knots (7 m/s) on average. This is due to the intensification of the trade winds and the presence of cold fronts from the north. In contrast, during the southwest monsoon season (May to October), the winds become weaker and more variable, often dropping below 10 knots (5 m/s) on average. This season is characterized by the dominance of the southwest monsoon, which brings warmer and more humid air from the Indian Ocean.
