Indonesia in February: Weather, Crowds & What to Expect

Sumatra (Northern and Western Sumatra)

Rain continues to dominate February in much of Sumatra. Aceh and the Barisan Range remain cloud-covered and wet, with waterfalls around Bukittinggi and Harau Valley running at full throttle and rivers rising quickly. The heavy rainfall keeps crowds thin at Lake Toba and makes wildlife spotting in Bukit Lawang more challenging because trails are muddy. Bring sturdy shoes and expect transport to be slower; short, heavy showers are the norm between clearer spells.

Java & Bali (Central and Eastern Java, Bali, Lombok)

Drenching downpours remain common through February from west Java to Bali, and Jakarta typically sees a series of heavy, short-lived floods that can disrupt roads and flights. Yogyakarta’s cultural sites stay open but muddy pathways restrict countryside cycling; Ubud in Bali is lush and quieter than in dry season but many outdoor activities are soggy. Travellers should carry waterproofs, allow extra transit time and consider indoor cultural experiences.

Kalimantan (Indonesian Borneo)

February continues the heavy-rain pattern with frequent cloudbursts and swollen waterways. Boat travel along the Kayan and Mahakam rivers is often the most reliable way to move goods and people, but expect delays and muddy banks at landing points. Wildlife-viewing trips still operate - orangutan sightings can be excellent when animals come to lower branches - though guides will emphasize safety on slick trails.

Sulawesi & the Maluku Islands

Frequent showers and high humidity remain in February, especially on Sulawesi’s west and central coasts. Manado and Bunaken in the north get substantial rain, which can reduce underwater visibility for diving and make some dive operators pause trips. Cultural tours inland continue but with muddy tracks; this is a quiet month for travel, good for bargain fares but not ideal for beach-oriented plans.

Nusa Tenggara & Komodo (Lombok, Sumbawa, Flores, Sumba, Komodo National Park)

Short bursts of heavy rain continue in February, but many days still have long sunny spells on Sumbawa and Sumba between storms. Flores’ highlands grow dramatically greener and Kelimutu’s crater lakes are atmospheric with misty mornings. Boat-based itineraries around Komodo can be less reliable so allow buffer days for returns to Labuan Bajo and bring layered clothing for smoky campfires and cool mornings.

Papua (Western New Guinea: Highlands and Coastal Papua, Raja Ampat area)

February continues as one of the rainier months across much of Papua, with persistent cloud and heavy showers that affect both coastal diving plans and highland trekking. Raja Ampat operators still run trips but visibility can be variable and sea states occasionally rough; the Highlands roads into Wamena remain slick and sometimes impassable. Allow flexible itineraries and expect fewer tourists in remote lodges.
