Bali has an equatorial and subequatorial maritime climate. Summer lasts almost all year round. There are two seasons: the dry season from April to October, and the wet season from November to March. During the wet season, an average of 10 rains fall per month, with about half of them happening at night. The average air temperature is +30°C, and the water temperature is +25 to +29°C, which allows tourists to swim year-round. Humidity is not high — on average around 75% — and is easy to tolerate. The wind sometimes picks up and helps to cope with the heat. The sun here is quite strong, so while staying under the sun (whether at the beach, on a tour, or just on a walk), we recommend using sunscreen

Weather in Bali by month:
January
It is considered the wettest month on the island. During the day, the thermometer can reach +34°C, but heavy tropical rains come after the hot daytime heat
February
Weather conditions are not very different from January. During the day, the air warms up to +31…+33°C. Local residents usually plan their activities for the second half of the day, after 16:00, when the sun becomes less intense
March
Rainfall gradually decreases, as the dry season will start soon. However, the weather can still be cloudy at times. During the day, the temperature is +26…+29°C. At night, it drops to +24°C
April
The rainy season retreats, the sun appears more often, and there are more sunny days — meaning you can enjoy your vacation even more. During the day, the thermometer shows around +32°C
May
It is considered the coolest month by local standards, though not by the standards of Russian-speaking tourists arriving from Russia and CIS countries. During the day, the thermometer shows +27°C, but at night it drops to +20°C
June
There is almost no rainfall. Air temperature is +26…+28°C. Very good weather!
July
The weather is the same: not too hot, and the nights are cool. You can sunbathe, swim, go on excursions, explore the surroundings, and enjoy water sports and other active развлечения
August
The driest month. Rain is very rare and usually short-lived. During the day, the thermometer shows +30°C, and at night +22°C. The sea is very warm at +28°C. The sun can be dangerous during the day, so you should use sunscreen
September
During the day the temperature is +31°C, at night +22°C. Mostly sunny weather — you can spend whole days on the beach, go shopping, or go diving or surfing. You will definitely like this climate
October
Daytime temperatures range between +26…+32°C. Gusty winds bring dry and hot air. Rain is still not very frequent, but humidity gradually increases
November
This month is characterized by frequent rains. Don’t be afraid: it doesn’t rain every day, and the weather will still радует you with sunny days. In clear weather, be sure to use sunscreen
December
Monsoons arrive on the island. It rains often, but for short periods, and only rarely can it last for several days. The ocean warms up to +30°C

Balinese weather is always changeable, and there is no fixed pattern or predictability. Therefore, no one can guarantee that it will always rain in December! Most often, ideal sunny days with low humidity happen in December. In my experience, January–February is usually more humid than December
