Assistant director of the National Weather Service (NWS) Jimmy Gomoga told Loop PNG that "the peak period of El Nino has just started."
He said the peak period of the dry season starts this month and goes until the middle of December.
Gomoga, who heads the NWS Forecasting and Warning Centre, said the country’s weather will return to its normal cycle in June next year.
El Nino is the effect of change in sea temperature and wind conditions, causing limited rainfall.
