The meeting brought together directors from the international development agency - the National Meteorological and Hydrological Services (NMHS), donor and funding agencies as well as the private sector to strengthen climate and weather services in the Pacific.
The head of the Tonga Met Service and president of the Asia-Pacific's World Meteorological Office, Ofa Fa'anunu, said NHMS directors felt a lot more investment should be going into dealing with extreme weather events in the region.
Mr Fa'anunu said the Pacific is at the forefront of the world's changing climate.
"We feel that the things that are happening today like stronger tropical cyclones, a lot more flooding, a lot more droughts, even tsunami are big issues in the Pacific," he said.
"These are the things that are affecting us daily. We don't need to wait for 30 years to see the impact, this impact is happening now."
The next PMC meeting will be in the Cook Islands in 2020.
