Bali is an island that has a tropical climate, meaning that it is hot all year round! This is one of the reasons why this beautiful island is so popular, as the tourist peak season lasts from April until October! This makes it extremely simple for travellers to miss out on that mad tourist rush, where Bali hotels are more expensive and there are lines for just about every activity. While the months from November to March are still warm, this is the time of year when Bali experiences the most rainfall and these months can experience an average of 90 mm of rain.
