The Central "Dry Zone"
When traveling to an area known as the dry zone, it’s not unreasonable to count on it being dry. This region best meets expectations from January to February and June to September, with the highest temperatures (86°F/30°C) cropping up in April and May. Such heat should come as no surprise for an island with such a close proximity to the equator, nor should impromptu rain showers throughout the year.

The Mountains
With the Indian Ocean and the Bay of Bengal surrounding Sri Lanka, monsoon winds gust over the island in seasons. May through September is when the mountainous parts of the land receive the most consistent rainfall, influenced by the winds of the Indian Ocean. Still, intermittent dry periods aren’t uncommon, and costs can be lower at this time, so travelers should be prepared for both rain and heat if visiting during this season.
One benefit of the higher elevation, more persistent rains and cooler temperatures is that it makes for ideal tea-growing conditions. Many think of tea plantations when they think of Sri Lanka, and travelers shouldn’t overlook the opportunity to lay eyes on the terraced magnificence of this cultural gem.

East Coast of Sri Lanka
Eastern Sri Lanka may be the hottest part of the country, but it’s also arguably the most steeped in tradition. It’s filled with fishing villages, quiet beach escapes, colorful markets, and natural beauty, and is home to the breathtaking natural harbor Trincomalee. Those seeking a romantic escape might be drawn to the more sparsely populated nature of eastern Sri Lanka
Popular destinations: Arugam Bay, Trincomalee, Batticaloa, and Kumana National Park
Southwest Coast of Sri Lanka
Galle and its surrounding beaches share similar weather patterns, remaining consistently humid, hot, and sunny—but also subject to periodic squalls. This southwestern region is considered the wet zone, but that doesn’t stop sunbathers from enjoying its quiet, blue waters and surfers from riding its easy breaks. The country’s capital, Colombo, is also found in this part of the island and is the hub of many festivals religious in nature.
