December Weather in Kotakinabalu
Is December Right for You?
Advantages
- Peak dry season with minimal rainfall - only 65mm (2.6 inches) compared to 200mm+ (8+ inches) in wet months, making it ideal for Mount Kinabalu climbs and island hopping
- Clearest visibility for wildlife spotting in Kinabatangan River - December's drier conditions mean animals congregate near water sources and morning mist clears by 8am instead of 10am in wetter months
- Perfect sea conditions for Sipadan diving with 25-30m (82-98 ft) visibility and calm currents - monsoon winds are at their weakest making boat transfers comfortable
- School holiday season brings vibrant night markets and extended operating hours - Gaya Street market stays open until 11pm instead of usual 9pm, with 40% more food stalls

- Peak tourist season pricing with accommodation rates 60-80% higher than shoulder months and advance booking essential for Mount Kinabalu climbing permits
