Vanuatu Meteorology and Geo-Hazards Department (VMGD) said Vanuatu has officially entered its dry season, with authorities warning communities to prepare for colder temperatures and reduced rainfall in the coming months.

The dry season has already begun across the islands and is expected to continue through to October.

The Principal Scientific Research Officer, John Ruben, said May is considered a transition month, with weather conditions expected to become noticeably drier during July and August.

“Usually the driest months are July, August and September, with August recording the lowest rainfall,” said Ruben.

Climate models also indicated the possible development of an El Niño to develop soon.

Although Vanuatu is currently in a neutral climate phase, meteorological agencies say the event could established between May and July.

“El Niño usually peak around November, December and January, when the effects becoming stronger across the Pacific during these months.”

Authorities say the developing conditions could increase pressure on water supplies, agriculture and health if rainfall drops below normal levels, cooler temperatures rises with much windy conditions.

Communities depending on rainwater harvesting are now being encouraged to check and manage water storage systems early in preparation for the months ahead.

Climate officials say monitoring of the dry season and potential El Niño conditions will continue over the coming months.
