The region experiences a tropical climate throughout the year, with consistent temperatures and high humidity, usually ranging from 25°C to 32°C (77°F to 90°F) in the lowlands. Higher altitudes, like Berastagi and Lake Toba, present noticeably cooler and more comfortable temperatures, especially in the evenings, which can drop to around 20°C (68°F) or even lower during the dry season.
