BMKG explains what’s really happening with Indonesia’s weatherand what expats should expect
If you’ve been in Jakarta or Bali recently and caught yourself wondering, “Isn’t it supposed to be dry season?” you’re not alone. Many residents and newcomers alike have been surprised by frequent rain showers even though the calendar clearly marks it as Indonesia’s dry period.
So, what’s going on?
According to the Indonesian Meteorological, Climatological, and Geophysical Agency (BMKG), this unusual weather pattern is what experts refer to as a “wet drought” a phenomenon that might sound contradictory, but has very real implications for daily life, travel plans, and even property decisions.
As Social Expat (2024) reported, BMKG attributes the irregular rainfall to changing global weather systems and emphasizes that this is not a sign of returning to the rainy season, but rather a side effect of shifting climate patterns in the region.
“The dry season is ongoing, but the atmosphere is moist enough to still produce moderate rainfall,”

What Is a Wet Drought?
The term wet drought describes a period where overall rainfall is still below average (meaning it’s officially dry season), but localized rains still occur due to increased moisture and specific atmospheric triggers.
This year, Indonesia is experiencing it due to several overlapping factors:
- Delayed effects of El Niño weakening over Southeast Asia
- Strong heating during daytime leading to afternoon cloud build-up
- High moisture content in the lower atmosphere
- Possible influence from Madden-Julian Oscillation (MJO), which brings temporary bursts of rain
As a result, we’re seeing brief but intense rainfall, sometimes multiple days a week, in regions that would typically remain dry from May through October.
What Does This Mean for Expats and Long-Term Visitors?
While the rain might disrupt afternoon outings or rooftop dinners, a wet drought isn’t necessarily a cause for concern—it just requires some planning adjustments.
Here’s what expats living in or relocating to Indonesia should know:
- Unpredictable Weather Calls for Flexible Planning
Afternoon rains might arrive with little warning. When scheduling site visits, school pickups, or leisure activities, consider the potential for short, high-intensity rainfall in the afternoon or early evening.
- Humidity Levels Stay High
Even in the so-called dry season, the “wet” conditions mean humidity remains elevated, which can impact comfort levels indoors. Properties with good ventilation or air-conditioning systems are a must.
- Drainage and Property Location Matter
For those seeking homes or investment properties, drainage infrastructure becomes even more crucial. Low-lying areas or properties without proper rainwater runoff may face issues—even during a “dry” month.
Impact on Property and Lifestyle in 2025
This evolving climate pattern is yet another reminder that weather resilience is becoming a key feature in property considerations. Whether you’re house-hunting in South Jakarta, exploring villas in Bali, or investing in commercial spaces, here’s what to look out for:
- Check building elevation and water flow direction
- Ask about roof condition and waterproofing measures
- Choose homes with sheltered outdoor areas, like covered terraces or semi-enclosed balconies
- Look for landscaping that supports water absorption, such as gravel paths or native plant gardens
In addition, neighborhoods that are well-prepared for climate variability—like those with wide roads, public green spaces, and reliable utility services—are seeing higher demand among both locals and expats.
It’s Still a Beautiful Time to Be in Indonesia
Yes, the weather might feel unusual—but it’s still a great time to explore, invest, and settle into life in Indonesia. The skies may bring the occasional rain, but they also bring lush greenery, cleaner air, and cooler afternoons—a silver lining for many.
“Don’t be too quick to label this a failed dry season. It’s still drier than usual overall—just not bone-dry,”
