Your April weather guide
HotWeather in Bali in April
Bali in April suits travellers who want hot weather and warm-water swimming, but can accept frequent rain. Daytime highs average 28°C, around 20 days have rain, and humidity reaches 85%, so this is not the month to choose for reliably dry outdoor days. For a UK traveller, the warmth is a clear change from spring at home; the catch is sticky conditions and the need to keep plans flexible.

Daytime and night-time in April
The typical April day in Bali peaks at 28.0°C, but that is an average: the warmest 10% of days reach 29.4°C or more. About 100% of days top 25°C and 1 in 23 pass 30°C. Nights average 24.8°C; one night in ten drops to 23.7°C or lower, so pack a layer for evenings. Between 1991 and 2020 the hottest April day here reached 30.9°C (2020-04-17) and the coldest night 21.2°C (1991-04-24).
Rain in April
Wet (more than 8 rainy days): about 20 days with 1 mm or more, 132 mm in total. Year to year it varies a lot - the wettest April was 1999 with 293 mm, the driest 2012 with 35 mm. Humidity averages 85%, which makes the heat feel heavier than the thermometer suggests.
Sea temperature in April
The sea averages 28.7°C - warm enough to swim (22°c+). Depending on the year it ranges from 28.0°C to 29.5°C. For the warmest sea here, come in February (28.9°C).
Sunshine and daylight
Around 3.9 hours of sunshine a day (estimated from cloud cover), 11.8 hours of daylight: the sun rises about 06:22 and sets about 18:17 local time in mid-April. Average cloud cover is 67%.
Is April a good time to visit Bali?
It is a reasonable choice: hot days but expect showers. The best months for Bali on our scoring are August, September, July; months averaging 25°C or more: Jan, Feb, Mar, Apr, May, Jun, Jul, Aug, Sep, Oct, Nov, Dec.
Hot days without much overnight relief
Expect summer-weight clothing throughout your stay, with average daytime highs of 28°C and night-time lows around 25°C. April ranks as Bali's warmest month, although days reaching 30°C are uncommon. The main consideration is humidity: the air can feel sticky even when the temperature does not look especially high. Loose, breathable clothes and accommodation with air conditioning are sensible choices, particularly if warm nights affect your sleep. Keep strenuous outdoor plans flexible and leave room for breaks at midday. Compared with London's April high of 13.5°C, this is a substantial jump in warmth, rather than a gentle step into milder weather.
Plan around rain, not uninterrupted sunshine
Rain is the main compromise in April. With about 20 rainy days, it makes sense to expect wet weather during your stay rather than treat it as an unlikely interruption. That does not mean every rainy day is a washout, but you should avoid a schedule that depends on staying outdoors throughout. Sunshine averages about 3.9 hours within 11.8 hours of daylight, so long days do not translate into continuous sun. Pack a light waterproof and something to protect your phone and other essentials. April is a reasonable choice if warmth matters more than clear skies; it is less convincing if dry weather is your priority.
