And for eastern regions, tucked behind the curtain of mountains running down the country, that meant dry days ... and plenty of them.
Times have changed.
About a decade ago, he said, the situation was that Hawke's Bay could expect a really searing drought every 20 years - but that it could end up being every five years.
"That would be catastrophic," he said.
January, February and March were traditionally dry months and for them to arrive in a situation where it was already "extremely" dry in many areas was not good.
"Excuse the cliche, but we could be looking down the barrel of a gun."
A 10-day moist easterly would be like winning Lotto for farmers across the region, but the way NIWA was predicting the situation, that was unlikely to front up before April or May ... and even that may not have the impact needed to start getting some growth under way for winter.
An 'oasis' effect could be achieved by massive plantings of trees and native bush and creation of storage dams and wetlands.
This would be a long-term plan for what he said could be long-term gain, given the way the climate was changing.
At this stage farmers were effectively hanging in there as they had in the past.
They had been prepared the best they could be, should the meteorological forecasts for a big dry come to fruition.
While there was good baleage and silage still out there, when that was gone, it was gone, he said.
There had been de-stocking before the summer and that had taken some heat off in terms of feed supply but a lot of farmers were doing it tough, and for many there were thoughts of giving it up.
"I'm 63 and my contemporaries are around the same age," he said.
In days past the children would grow into the position of taking on the farm but that had changed.
Most young people moved either to the cities or overseas where they installed themselves in jobs they were comfortable with.
"A lot of kids don't want to go back on to the farms." Events like potential droughts did not help.
"There will be a lot of psychological stress on a lot of people as this goes on ... day after day," Mr Gilbertson said.
