During the month of April, Sri Lanka experiences a transition period between the two monsoons. The southwestern region, including Colombo and Galle, typically sees the beginning of the Yala monsoon season, bringing increased humidity and rainfall, particularly in the latter half of the month. The northeastern region, including Trincomalee and Jaffna, generally enjoys drier, sunnier conditions as the Maha monsoon season ends. Temperatures island-wide remain warm, averaging between 27-32C (81-90F).
Understanding these climatic conditions is crucial for travelers planning visits. Foreknowledge allows for appropriate packing and itinerary adjustments. The timing of the Yala monsoons arrival impacts agricultural practices and water resource management, making it a significant factor in the country’s annual cycle. Historically, these seasonal patterns have shaped cultural practices and festivals tied to rainfall and harvests.
