Here, temperatures are significantly milder, ranging from a cool 14°C (57°F) in the early mornings and evenings to a pleasant 24°C (75°F) during the day. A light jacket or sweater is highly recommended for the Highlands, especially after sunset.

Yala Monsoon (May – September): Brings rain to the Southwest and Western coasts (e.g., Colombo, Galle, Mirissa) and the Hill Country. The North and East (e.g., Jaffna, Trincomalee) are generally dry and sunny during this period.
