April weather forecast
Sri Lanka

April stands out as one of the warmest months in Sri Lanka's annual climatic calendar. The nation experiences temperatures typically varying between 20°C (68°F) to 26.5°C (79.7°F). However, it's crucial to note the cooler exceptions like Nuwara Eliya. This city, nestled in the central highlands, witnesses a climate contrast with temperatures oscillating from 10°C (50°F) to 23°C (73.4°F).

Compared to March, April exhibits a more pronounced warmth, asserting itself as one of the peak hot months alongside May. The increase in temperature is felt across the island, making mid-day activities a bit strenuous for those unaccustomed to tropical heat.

While rain remains sporadic, there's an increase in humidity, contributing to a feeling of stickiness, especially in coastal regions. This moisture-laden atmosphere heralds the impending arrival of the southwest monsoon. Regions that are not yet experiencing the monsoon's impact, such as Batticaloa on the eastern coast, have reduced rainfall in comparison to the earlier months of the year.

As April gives way to May, Sri Lanka prepares for the full brunt of the southwest monsoon. The subsequent month not only retains the heat but also introduces heavier rainfall, especially in the southwestern parts of the country.
