This guide breaks down Galle’s weather month by month and helps you choose when to visit.
Galle is a must-visit coastal city in Sri Lanka. It is renowned for its UNESCO-listed 17th-century Dutch fort, blending colonial history with a vibrant, modern atmosphere. Visitors often enjoy the cobbled streets, colourful boutique shops, seaside cafes, and iconic lighthouse.
Key Reasons to Visit Galle:
Galle has a tropical climate, which means it is always hot and humid year-round. The temperature hovers around 25 to 31°C. Galle's primary rainy season is driven by the southwestern monsoon. It occurs from May to September, with the heaviest rainfall usually between June and August. While heavy, these rains often come in short, intense bursts rather than all-day downpours. The best time to visit Galle is from December to April, when the weather is dry, sunny, and perfect for beaches and sightseeing.
