Report Industry Investment Rating - Not provided in the report Core Viewpoints - As of the end of November 2025, the El Niño index was -0.55, and the Southern Oscillation Index was continuously positive, indicating the formation of La Niña. By early 2026, its intensity remained weak, and the overall rainfall in Southeast Asia showed no significant deviation, currently having limited impact on palm oil-producing areas. The Southern Oscillation Index is gradually approaching the 0 axis, suggesting that La Niña may be nearing its end [1] - This week, rainfall in the Malay Archipelago remains low. There is almost no precipitation in the Malay Peninsula, with sporadic rainfall in East Malaysia. The rainfall in Kalimantan Island, Indonesia, is slightly higher, while that in Sumatra Island and its surrounding areas is limited [1] - In terms of soil moisture, the southern part of the Malay Peninsula remains dry, and the drought may spread further in February. By March, the entire Malay Peninsula may experience drought. In Sabah and Sarawak, the rainfall is sufficient, and the soil moisture is good across the region, with no drought concerns. In Indonesia, there has been rainfall in Kalimantan Island and Jambi this week, but the soil moisture in Riau and North Sumatra is decreasing. If the rainfall does not improve in February and March, there may be a risk of drought [2] - With limited short - term rainfall and no severe weather disasters, continuous attention should be paid to areas with low soil moisture.

The Southern Oscillation Index is gradually approaching the zero - axis, indicating that La Niña may be nearing its end [1]. - This week, rainfall in the Malay Archipelago remains scarce. Most parts of Indonesia have received some rainfall, but the amounts are still limited. The soil humidity in the southern Malay Peninsula is dry, and drought may spread in February and March. Some regions in Indonesia may also face drought risks if rainfall does not improve in February and March. Short - term lack of rainfall and persistent poor soil humidity in some areas may affect palm oil production in the second half of the year [1][2] Summaries by Relevant Catalogs Weather Forecast - **El Niño and Southern Oscillation Index**: As of the end of 2025, the Southern Oscillation Index exceeded the threshold of 1, and the El Niño index was - 0.55 as of the end of November. The Southern Oscillation Index has remained positive, indicating the formation of a La Niña phenomenon. As of early 2026, its intensity has been weak, and the overall rainfall in Southeast Asia has not shown significant deviations, currently having limited impact on palm oil production areas. The Southern Oscillation Index is gradually approaching the zero - axis, suggesting that La Niña may be nearing its end [1]. - **Weekly Weather**: This week, rainfall in the Malay Archipelago remains scarce. The Malay Peninsula has almost no precipitation, with only sporadic rainfall in East Malaysia. Most parts of Indonesia have received some rainfall, but the amounts are still limited [1]. - **Soil Humidity**: The soil humidity in the southern Malay Peninsula is dry, and drought may spread in February and expand to the entire Malay Peninsula in March. In Sabah and Sarawak, rainfall is sufficient, and soil humidity is good. In Indonesia, although most areas have received rainfall, the amounts are lower than the same period last year. Soil humidity in Riau, Central Kalimantan, and North Sumatra is decreasing, and these regions may face drought risks if rainfall does not improve in February and March [2]. Regional Palm Oil Production Areas Indonesia - **Jambi**: Rainfall shows a downward trend, but soil humidity is good, and there is currently no drought disturbance [25]. - **West Kalimantan**: Rainfall decreases towards the end of the month, and attention should be paid to changes in soil humidity [29]. - **Central Kalimantan**: Rainfall is decreasing, and soil humidity may decline [37]. - **East Kalimantan**: Precipitation is abundant, and the soil is moist [42]. - **Riau**: Rainfall increase is insufficient, and soil humidity is decreasing [50]. - **South Sumatra**: Rainfall is rising, and soil humidity is expected to exceed the average level of the past 20 years [57]. - **North Sumatra**: Rainfall was limited in January, and soil humidity is decreasing [63].
