Bali Rainy Season Guide: December-February

For readers planning to visit Bali at the end of this year or early next year, have you seen our latest announcement in the Facebook group from Indonesia’s BMKG (Meteorological, Climatological, and Geophysical Agency)? It’s a warning about heavy rainfall from late December to early January, a period that deserves special attention during the annual rainy season. As a long-term resident of Indonesia and frequent traveler to Bali, I’ve compiled a guide to help you plan your trip for January-February 2027 with more clarity.

🌧 Rainfall to Reach 300-500mm: Peak Rainy Season from Late December to Early January

BMKG’s forecast indicates that Indonesia will enter a period of intensified rainfall at the end of December, with the heaviest precipitation expected between December 28 and January 10, accompanied by frequent showers and thunderstorms. Generally, the weather during this period follows this pattern:

• Occasional morning sunshine
• Increasing rainfall from noon to afternoon
• Possible evening rain depending on cloud systems This isn’t the “worst storm of the year,” but it’s indeed the 10-14 days during the rainy season that require heightened awareness.

⚠️ What Travelers Should Note: Not Dangerous, But Be Prepared

Bali remains enjoyable during the rainy season, but this period does bring some noticeable impacts, including:

• Flight delays: Afternoon thunderstorms often cause temporary flight suspensions or delays.
• Unstable sea conditions: Large waves and poor visibility affect snorkeling, speedboat rides, and island hopping.
• Waterlogging and localized flooding: Especially in certain areas of Denpasar and coastal roads.
• Variable mountain road conditions: Occasional landslides or muddy trails on waterfall routes and mountain paths. For travelers, these aren’t dangerous enough to cancel trips, but they do require adjusting “itinerary pacing” and “expectations.”

🌤 Don’t Misunderstand! Sunny Days Still Exist During Rainy Season, and You Can Still Have Fun

I know many people get nervous seeing “heavy rainfall” and “300-500mm,” imagining their entire trip will be soaked. But Bali’s rainy season doesn’t mean continuous downpours - it’s characterized by “frequent short showers + afternoon thunderstorms.” The actual experience is usually:

• Beautiful morning sunshine, with some areas even having clear blue skies
• Weather changes around noon, with alternating heavy and light rain
• Often stabilizing in the evening, allowing for dining, shopping, and photography So what travelers really need to do is “make the most of good weather in the morning.”

🎒 Bali Travel Recommendations for January-February 2027

Here are some recommendations based on years of experience and BMKG’s warnings this year:

- Avoid island hopping trips from New Year’s to January 10th

This includes Nusa Lembongan, Nusa Penida, and Gili T, to prevent boat cancellations or extreme seasickness.

- Schedule beach and outdoor activities for the morning

If you want to photograph rice terraces, waterfalls, Tanah Lot Temple, or Monkey Forest… mornings offer much higher success rates.

- Prepare waterproof gear

Lightweight raincoats, waterproof bags, sandals, and quick-dry clothing are lifesavers during the rainy season.

- Keep your itinerary flexible

Don’t pack every day full of activities, so you won’t panic if the rain suddenly intensifies.

- Rainfall becomes more ‘predictable’ from mid-January onwards through February

Rain will still fall, but the rhythm feels more like the typical rainy season, not as intense as during the New Year period.

🌈 Bali in the Rainy Season is Actually Quite Charming

Honestly, I have a deep affection and reliance on Bali during this time. After a rain shower, the entire island feels cleansed: the air is crisp, the greenery is lush, the waterfalls are spectacular, and Ubud’s rice fields resemble a painted masterpiece. With fewer tourists than in peak season and more affordable accommodations, this period can be even more comfortable for those who enjoy slow travel, capturing natural landscapes, indulging in delicious food, and enjoying spa treatments.

The rainy season is never an obstacle to travel; it simply reminds you to adjust your pace.
