We have a largely dry period of weather in Bali right now. The dry season has actually given us some light showers and cooler than normal (maybe its just me that cold!) night time temperatures.
Looking at the 10 day weather forecast for Bali, we see the coastal areas have some scattered cloud but no chance of rain. Great time of the year for hiking, since the trails are dry and humidity is lower. Some of the hikes I recommend include Gunung Catur in Bedugal and the Campuhan Ridge Walk in Ubud, starting at Pura Gunung Lebah
