Monthly weather averages & travel planning

Updated: March 2026
April is a fair time to visit Bali (5/10). With 10 daily sunshine hours and only 24 rain days, this month delivers genuinely reliable outdoor conditions, ranking it 9th sunniest of the year in Bali. Culture-focused travellers and those who prefer lighter crowds will find April a practical choice, with prices running lower than peak September without sacrificing all the good weather. May offers a similar profile at lower hotel rates if dates are flexible. Watch out for prolonged rain stretches: with 24 wet days, a fully outdoor itinerary is risky. Build in museum days and covered market visits as contingency. Planning tips: accommodation is generally available without long lead times, and flight prices are typically lower than peak season. Flexible travellers will find the best deals by booking 2-4 weeks ahead. Mid-week arrivals consistently unlock lower hotel rates than weekend check-ins.
April sits at a particular moment in Bali's seasonal arc. Temperatures average 28°C during the day, placing this month in the warmer half of the year, when the city operates at full summer intensity. Against the seasonal backdrop, 24 rainy days and 10 sunshine hours per day help calibrate expectations for what actually awaits on the ground.

The narrow 3°C gap between daytime and overnight temperatures, characteristic of coastal cities with maritime moderation, means a single mid-layer works across the whole day. At 82% humidity, the 28°C daytime high feels 2-4°C warmer in practice: quick-dry fabrics and shade-seeking between noon and 3pm are the sensible response. UV index averages 6 this month, classed as moderate. Sunscreen is a sensible precaution for extended outdoor time, particularly at midday. Winds are calm at an average 11 km/h, so wind-chill is not a factor in planning your clothing. In Fahrenheit: 82°F average high, 77°F overnight low.

Packing for Bali in April means dressing for 28°C days and 25°C evenings. A light cotton tee with a casual overshirt works well at 28°C, the overshirt doubles as a layer for air-conditioned venues. Evening temperatures settle at 25°C, a modest 3°C drop that a light cardigan or denim jacket covers. Comfortable walking trainers are the versatile choice for both outdoor sightseeing and indoor venues. With 24 rain days expected, a compact travel umbrella is worth the bag space. A waterproof jacket is better than an umbrella if you plan full-day outdoor routes. For temple and religious site visits, carry a lightweight scarf or sarong to cover shoulders and knees, required at most major sites across the region. At 82% average humidity, quick-dry synthetic or bamboo fabrics dry overnight and stay comfortable longer than cotton.
Local tip: Temple and religious site visits require covered shoulders and knees in most of Bali's heritage areas. A lightweight scarf or sarong weighs almost nothing and solves the problem instantly.
April has no major festivals or public holidays in Bali, which is one of its practical advantages for independent travellers. Attractions run at lower capacity than during peak event periods, queues are shorter, and accommodation is easier to find without needing to book many months in advance. Local restaurants, markets, and transport operate at a relaxed pace, making this an ideal time for visitors who prefer a more authentic, unhurried experience of everyday city life rather than large crowds drawn in by a single major headline event.
Based on 28°C average highs and 24 rainy days
In April, Bali sits in the dry season corridor, as the ITCZ shifts away from the region and trade winds bring drier, more stable air. This produces reliably sunny days reaching 28°C, with lower humidity than the wet months. Overnight lows of 25°C offer a pleasant reprieve from the midday heat. Climate data: Open-Meteo ERA5 (1991–2020).
Sunshine Hours
The average number of hours per day with direct sunlight. Calculated from satellite measurements. Days with more than 7 hours of sunshine are ideal for outdoor activities. Under 3 hours means overcast conditions dominate.
UV Index
A scale from 0-11+ measuring ultraviolet radiation intensity. UV 0-2: Minimal risk. UV 3-5: Moderate, wear sunscreen. UV 6-7: High, hat and SPF 30+ essential. UV 8-10: Very High, limit midday exposure. UV 11+: Extreme, seek shade between 10am-4pm.
Rain Days
A rain day is counted when precipitation exceeds 0.1mm. This threshold captures even light drizzle. Unlike total rainfall in mm, rain days tells you how often you might need an umbrella, which is useful for planning outdoor activities.
Humidity
Relative humidity as a percentage. Below 40%: Dry, skin and throat may feel parched. 40-60%: Comfortable, ideal for most people. 60-80%: Sticky, light breathable fabrics recommended. Above 80%: Muggy, heat feels more intense; quick-dry clothing is essential.
