How to Decide the Best Time to Travel to Borneo
Understanding Borneo’s Unique Climate Patterns
Borneo experiences a tropical climate and operates on two main seasons: dry (March–October) and wet (November–February)[1]. While rain can occur at any time, the seasonal distinction directly influences outdoor activities, wildlife encounters, and travel costs. The island’s microclimates vary regionally, especially in Sabah and Sarawak, affecting local experiences.
Seasonal Weather Overview (2026)
- Average Temperatures: 26°C–32°C throughout the year[2].
- Rainfall: Peaks in January & December (~350–480mm/month) and drops to ~120mm in June.

2026 weather projections align with recent climate trends, including the dry season offering clearer skies and lower humidity.
