Bali Rainy Season 2026–27: Month by Month, and When It Ends

Bottom Line First: BMKG predicts the 2026 rainy season will end early, with the dry season kicking off in April—making it prime time for significantly higher success rates for summiting Mount Bromo on Java and better water visibility for diving and surfing in Bali. If you’re planning a “two-island cross-sea itinerary,” this is the optimal window: Java for culture and volcanoes (Borobudur, Mount Bromo), Bali for relaxation (Ubud’s rice terraces, southern coast resorts).

As April 2026 approaches, Indonesia’s Meteorology, Climatology, and Geophysical Agency (BMKG) has signaled the end of the rainy season. For travelers who love deep exploration, now is the perfect time to plan a “two-island cross-sea trip.” On one side is Java, rich in cultural heritage and majestic volcanoes; on the other is Bali, showcasing ultimate island charm. These two islands, separated only by a narrow strait, have distinctly different personalities.

When is Bali’s Rainy Season? (Monthly Rainfall Comparison)

Bali’s rainy season runs from November to March, and the dry season from April to October. The wettest month is January (about 388 mm of rain, roughly 19 rainy days), while the driest is August (about 16 mm, roughly 2 rainy days).

But the numbers don’t capture what Bali’s rain actually looks like: except for the peak in January–February, it’s mostly a heavy afternoon downpour that stops within an hour or two, not a constant drizzle all day. Mornings are usually sunny. That’s why many people still visit in November, December, and March—just schedule outdoor activities in the morning and keep afternoons flexible.

Month	Average Rainfall	Rainy Days	Season
January	388 mm	19 days	Rainy season · Wettest month
February	299 mm	17 days	Rainy season
March	214 mm	13 days	Rainy season, easing up
April	115 mm	9 days	Transition to dry season
May	73 mm	7 days	Dry season
June	51 mm	5 days	Dry season
July	30 mm	3 days	Dry season · Peak season
August	16 mm	2 days	Dry season · Driest month
September	41 mm	3 days	Dry season
October	68 mm	5 days	Transition to rainy season
November	149 mm	10 days	Rainy season begins
December	299 mm	16 days	Rainy season · Christmas & New Year peak

The above figures are long-term averages for southern Bali (Denpasar). Ubud and the central highlands are noticeably wetter, while the southern Uluwatu peninsula and the northern coast around Lovina are relatively drier.

Java: Stepping into the Threads of History and Nature

Java is the heart of Indonesia. If you’re craving a baptism of culture and adventure, this island will not disappoint.

• The Awe of Ancient Civilization: Visiting Yogyakarta, watching Borobudur emerge from the mist at dawn offers an irreplaceable sense of inner peace.
• The Majesty of Volcanoes: As the rainy season winds down, your chances of successfully climbing Mount Bromo increase significantly. Standing at the crater’s edge, listening to the deep rumble of the earth, you feel the raw vitality of Java.

Bali: Rediscovering Life’s Slow Pace

Crossing the strait to Bali, the rhythm of the air instantly slows down. This is a sanctuary for healing the mind and body, and the pinnacle of vacation aesthetics.

• Ultimate Resort Atmosphere: Whether it’s the lush green rice terraces of Ubud or the upscale resorts along the southern coast, the design here always harmonizes with nature.
• The Call of the Ocean: As the dry season approaches, Bali’s waters become clearer, making it an ideal time for diving and surfing enthusiasts.

2026 Seasonal Travel Tips

According to the latest weather forecasts, this year’s dry season in Indonesia is expected to arrive slightly earlier than usual.

• Best Time: Mid-to-late April is an excellent turning point. Rainfall decreases while the vegetation remains lush, making colors pop in photos.

In the first half of 2026, there are several opportunities to ‘take 4 days off for a 9-day holiday’—start planning now!

Exact Date When the Rainy Season Ends?

According to the latest official news from Indonesia’s Meteorology, Climatology, and Geophysical Agency (BMKG) released from March to early April 2026, there is currently no single nationwide ‘exact end date’ (such as a specific day of the month). Instead, predictions are made in phases based on each ‘Seasonal Zone’ (ZOM).

Here is a summary of the specific time points mentioned in media reports:

Key Timeline for the Seasonal Transition

Based on statements from BMKG head Teuku Faisal Fathani, the climate turning points for 2026 are as follows:

• Official End of Rainy Season / Start of Dry Season:
  • April: Approximately 16.3% of regions will enter the dry season first, starting from eastern Nusa Tenggara.
  • May: About 26.3% of regions (including Bali and parts of Java) will enter the dry season.
  • June: The remaining 23.3% of regions will follow.
• Peak of Dry Season: Around 61.4% of all Indonesian regions will reach their driest peak in August 2026.

Why Is There No Exact Date?

BMKG notes that the seasonal transition across Indonesia progresses ‘from east to west,’ so the dates vary:

• Eastern regions (e.g., Lombok, Sumbawa): Begin turning dry in early April.
• Central regions (e.g., Bali, East Java): Expected to complete the transition from mid-to-late April to early May.
• Western regions (e.g., Sumatra, West Java): May not fully enter the dry season until late May or June.

Special Climate Warnings for 2026

Media outlets have particularly highlighted how this year differs from previous ones:

• Early Onset: Nearly half (46.5%) of the country’s regions will see the dry season start earlier than usual.
• Extreme Dryness: With the weak La Niña ending in February and a possible weak El Niño emerging in July, BMKG predicts this year’s dry season will be longer and drier than in 2025.
• Transition Warning: Early April is currently in the Pancaroba (transition season). While the rainy season is ending, strong afternoon thunderstorms, high winds, and even hail are still possible. BMKG reminds the public to stay alert for sudden extreme weather during this transition period.

If you’re planning activities in Bali or Java, media reports citing BMKG suggest that after mid-April, the weather will become noticeably more stable, with rainfall frequency dropping significantly, marking the start of a season ideal for outdoor activities.
