In December - February, the rainy season occurs. In different years, it can vary in severity and timing. During the rainy season, it doesn't necessarily rain all day and every day. However, the cloud cover is quite consistent and the sun isn't as strong. Due to the humidity, sweating is very common. The higher the area is located in Bali, the more humid it is and the higher the chance of rain. For example, Ubud experiences more rain than Nusa Dua or Canggu.
During this time, Europeans usually travel to Bali. Overall, the rainy season is the low season in Bali, except for the period that includes Christmas and New Year (peak season) and Chinese New Year (high season).
In June - August, the dry season occurs. It can also vary and be uneven. The sky is clear, almost cloudless. This season is windier, and evenings can be quite cool. Even during the dry season, there can be rains in the highland areas of Bali.
During this season, the number of Australians and Brazilians in Bali increases. Tourists, in general, become more numerous. The period of June - August is the high season in Bali.
Between the dry and wet seasons, there's a transitional period. It can be either dry or rainy.
Here's a breakdown of the weather in Bali by month.
Weather in Bali in January:
January is the rainiest month of the year in Bali. It's not uncommon for rain to persist for several days in a row, especially in early January. There's also a high chance of stormy winds. The average temperature is relatively high, but due to frequent cloud cover and rain, the heat isn't felt intensely. The ocean is very warm, just like the rain. In January, there are many Russian tourists in Bali, especially in Nusa Dua hotels. On the western side of the island (Kuta, Jimbaran, Seminyak), the sea can be dirty and rough. Surfing mainly occurs at surf spots on the eastern side.

March is one of the hottest months in Bali. Beware of walking around at noon as you might get heatstroke. If you do go out during the day, wearing a hat is advisable, try to stay in the shade, and drink as much cool (but not cold) water as possible. If you're on the beach, consider frequently dipping into the ocean. Generally, keep in mind that the central part of the island (e.g., Ubud) tends to have much rainier weather than the south of Bali.
