The southwest monsoon, which lasts from May to September, brings abundant rainfall to the city, with average monthly precipitation exceeding 200 mm.

Conversely, the driest months are February and March, with average rainfall below 50 mm. This seasonal variation in rainfall is closely linked to the prevailing wind patterns and the movement of the Intertropical Convergence Zone (ITCZ), a low-pressure belt that brings heavy rainfall to equatorial regions. During the southwest monsoon, the ITCZ shifts northward and brings moisture-laden winds from the Arabian Sea over Sri Lanka, resulting in heavy rainfall over the western coast.

Moon in Sri Jayewardenepura Kotte

The Moon’s position and visibility in Sri Jayewardenepura Kotte, the administrative capital of Sri Lanka, varies throughout the month and year due to the Earth’s rotation and the Moon’s orbit around the Earth. The Moon’s phases, which include New Moon, Waxing Crescent, First Quarter, Waxing Gibbous, Full Moon, Waning Gibbous, Third Quarter, and Waning Crescent, are determined by its position relative to the Sun and Earth.

During New Moon, the Moon is not visible from Earth because it is located between the Earth and the Sun. As the Moon orbits the Earth, it gradually moves away from the Sun, becoming visible as a thin crescent in the western sky just after sunset. This phase is known as Waxing Crescent. Over the next few days, the Moon continues to grow in size, becoming a First Quarter Moon when half of its surface is illuminated. The Waxing Gibbous phase follows, during which the Moon appears more than half full and rises later each night.

General Humidity Patterns

Sri Jayewardenepura Kotte, the administrative capital of Sri Lanka, experiences tropical climate characterized by high humidity levels throughout the year. The average relative humidity ranges from 75% to 85%, with slight variations depending on the time of day and season. During the Southwest Monsoon season (May to September), humidity levels tend to be higher, particularly in the late afternoon and evening. Conversely, during the Northeast Monsoon season (December to February), humidity levels are slightly lower, but still remain within the high range.

Seasonal Variations

The seasonal variations in humidity are primarily influenced by the monsoon patterns. During the Southwest Monsoon season, the prevailing winds from the Indian Ocean bring moisture-laden air masses, resulting in increased humidity levels. This is further exacerbated by the frequent rainfall, which adds moisture to the atmosphere. In contrast, during the Northeast Monsoon season, the winds shift to the northeast, bringing drier air from the Asian continent. As a result, humidity levels decrease, although they remain significantly high.

Wind Patterns

Sri Jayewardenepura Kotte, located near the southwestern coast of Sri Lanka, experiences a monsoon climate with distinct wind patterns. During the southwest monsoon, from May to September, strong southwesterly winds prevail, bringing abundant rainfall to the city. These winds are associated with the Intertropical Convergence Zone (ITCZ), a low-pressure area where winds from the Northern and Southern Hemispheres converge.

During the northeast monsoon, from December to March, weaker northeasterly winds prevail, bringing drier conditions. These winds originate over the Bay of Bengal and carry relatively little moisture. Between April and November, during the inter-monsoon periods, the wind direction becomes more variable, and the city experiences a mix of both southwest and northeast winds. The wind speed also varies throughout the year, with stronger winds during the monsoon seasons and lighter winds during the inter-monsoon periods.
