BMKG Warns of Potential Rain and Strong Winds During Early Eid Homecoming Period 2026
The Meteorology, Climatology and Geophysics Agency (BMKG) has provided weather forecast information for the early Eid homecoming period in 2026. Overall, atmospheric conditions across most of Indonesia remain conducive, though residents are advised to remain alert to potential rainfall accompanied by lightning or thunder, as well as strong winds in several regions.
BMKG Head Teuku Faisal Fathani urged the public to remain calm yet vigilant regarding weather developments during the 2026 Eid journey. He emphasised the importance of accessing information from official sources to prevent the public from being influenced by potentially inaccurate information.
“Continue monitoring updated land, sea, and air weather information to adjust your homecoming travel plans through various official BMKG channels,” Faisal stated on Sunday (15 March).
Deputy of the Meteorology Division Andri Ramdhani explained that current atmospheric dynamics are influenced by the active Madden–Julian Oscillation (MJO) in Indonesia’s southern and eastern regions. These conditions are further reinforced by Equatorial Rossby wave and Kelvin wave activity around Indonesia during 13–20 March 2026.
According to him, the combination of these factors increases the potential for rain cloud development in several regions, particularly supported by high air humidity and moderately unstable atmospheric conditions.
BMKG forecasts moderate to heavy rainfall potentially occurring during 14–17 March across parts of Sumatra and Central and East Java. Subsequently, rainfall is also predicted for 18–20 March 2026 in parts of South Sulawesi and Papua.
Beyond land areas, significant weather potential is also expected in air transport sectors. BMKG identified possible widespread Cumulonimbus cloud development along several homecoming routes, particularly in the Maluku Sea and northern Papua regions. The probability of such cloud formation is forecast to exceed 75 per cent, requiring attention from aviation activities.
“BMKG also predicts high waves exceeding 2.5 metres may occur in the Maluku Sea and northern Papua waters, which could affect maritime transport activities. Additionally, coastal residents in North Sumatra, West Sumatra, Central Java, East Java, East Nusa Tenggara, and Kalimantan regions should also remain alert to potential tidal flooding forecast to occur intermittently from 14 to 19 March 2026,” she stated.
Responding to these conditions, Acting Director of Public Meteorology Ida Pramuwardani advised the public and homebound travellers to regularly monitor BMKG weather forecast updates.
She also reminded residents to prepare emergency equipment before travelling and increase caution when driving in rainy conditions. Additionally, residents are urged to ensure their homes are safe from potential hydrometeorological risks before being left unoccupied.
BMKG also called on the public to remain calm and rely solely on weather information from official government channels to avoid spreading false information or misinformation regarding weather during the 2026 Eid homecoming.
