In a month which saw torrential rain across large parts of the north coast, the town of Forster was the only centre to actually break a rainfall record.
The Weather Bureau said Forster's January rainfall of 525 mm was five times the monthly average.
Bureau spokesman Aaron Coutts-Smith said it smashed a record of 404 mm set in January 1951.
He said the Bureau expects the next three months to be drier than average.
"We have a look at the ocean conditions across the Pacific and Indian Ocean and look at what the rainfall was like across Australia when conditions were like that in the past," he said.
"So we use that as an indication and that tells us that we've actually got slightly drier than average conditions expected over the February to April period and we're expecting around average in terms of temperatures."
