"All of [last year] was relatively dry, so it's just been an accumulation of dry weather. There's not a lot of groundwater [in Hawke's Bay]."
He said that in recent years the autumn season had been lacking in rain.
"We wish it wasn't but, for whatever reason, the climate seems to be changing in a way that a dry autumn is becoming the new normal."
Niwa forecaster Chris Brandolino said Hawke's Bay could expect increasingly dry weather in the coming decades, thanks to climate change.
"As our climate changes and evolves, there will be more frequent and extreme weather events, including droughts."
He said time spent in drought in the eastern North Island was expected to double or triple by 2040.
MetService forecaster Nicole Ranger said residents could expect fine weather today, with northwesterly winds freshening tomorrow, and a possibility of gales in exposed places on Thursday.
Rain was expected about the western hills on Thursday, clearing on Friday, which would become fine in the afternoon.
Saturday was looking fine.
