BMKG Says La Nina Anomaly Exists amid Dry Season in August-October

TEMPO.CO, Jakarta - The dry season has occurred in parts of Indonesia for the next three months until October, the Meteorology, Climatology, and Geophysics Agency (BMKG) has reported. However, the La Nina climate anomaly has the potential to trigger rainfall.

During August-October, above-normal rains are expected in regions south of the equator, including Java. Many of the areas are also forecasted to see high potential for flood, including several districts in Banten and West Java.

In October's forecast, the potential for flooding in Jakarta will increase from safe to medium status or one status level below high. Several regions near the river upstream that flow into the capital will likely see heavy rainfall and flooding.

Head of the West Java Climatology Station, Indra Gustari, said the climate in most parts of Indonesia for the past two years has been relatively wetter than average. This means that in general, the rain falls higher than usual.

The main factor, according to Indra, is the La Nina phenomenon which develops from weak to moderate intensity, leading to an increase in rainfall in most parts of Indonesia, including West Java.

“La Nina can cause the rainy season to come earlier and last longer and cause the dry season to come late and have a shorter duration,” Indra told Tempo on Thursday, August 11, 2022.
