Penang Hill has a tropical rainforest climate with fixed temperatures that are usually lower than the surrounding areas because of the station’s higher altitude. The annual average temperature is around 21 – 22 degree Celsius. Variations are very minute and the temperature is constant year-round. Precipitation levels are generally quite high all over the year.
The best time to visit Penang Hills is the time when rainfall levels are very low. This is usually during the December to February period. The temperature will be a little hot, but very few showers make up for the increase in temperature. Humidity levels are also comparatively lower.
