The Sembalun Rinjani route is the most popular trekking route to the summit of Mount Rinjani in Lombok. However, during June and July, the Sembalun Rinjani area experiences a significant drop in temperature. The cold weather along the trekking route increases the risk of hypothermia, especially for hikers camping overnight in areas such as Pelawangan Sembalun.
Why Is the Sembalun Rinjani Route So Cold During the Dry Season?
The Sembalun Rinjani route is widely recognized as one of the most popular trails leading to Mount Rinjani. However, beyond its breathtaking scenery, this area is also known for experiencing extreme temperatures during the dry season.
According to meteorological experts, the southeast monsoon winds carrying cold air from Australia cause temperatures in the Sembalun Rinjani region to become lower than usual. In addition, clear skies with little cloud cover allow heat from the earth’s surface to escape more rapidly at night, causing temperatures in the highlands of Sembalun Rinjani to drop significantly.
At certain elevations along the Sembalun Rinjani route, nighttime temperatures can fall to as low as 0–5°C, particularly around popular camping areas such as Pelawangan Sembalun.
