Just months after the Hawke's Bay landscape sat parched and dry, a series of substantial bouts of rain have left the region rejuvenated.

Metservice meteorologist Lisa Murray said with more than one week left in April the city of Napier had already doubled its average rainfall for the month.

Representing data collated from 1991 to 2003, Metservice's long-term mean rainfall for Napier in April suggests rainfall should measure 80.5mm. Yesterday the figure was 162mm.

In Central Hawke's Bay, Mount Vernon homestead owner Richard Harding said he had been monitoring the rainfall levels with the historic homestead's rain gauge.


Central Hawke's Bay had already received half of it's annual rainfall and this was due to weather patterns and the heavy downpours brought by cyclones, Mr Harding said.

"March was wet and now April is exceptionally wet. You get that every now and again anyway. Cyclones blow the rainfall figures out."

Mr Harding said he had observed 400mm of rainfall already this year, with previous years' figures ranging between 650mm and 1100mm; 1100mm representing a very wet year.

While a wet month, Mr Harding said looking at patterns over 100 years this did happen from time to time.

Rainfall data from the past month has shown mass rainfall totals throughout Hawke's Bay; with no area going unaffected by the past wet month.

Between 4pm on March 20 and 4pm on April 20 Wairoa received 298mm, Te Pohue 364.5mm, Napier 199.2mm, and Takapau 275.8mm.

Ms Murray said much of rain had been seen during Cyclone Cook on the 12th and 13th of April, as well as April 4 in what was the remnants of Cyclone Debbie.

Last Thursday Metservice issued a severe weather warning for strong wind in Hawke's Bay, warning locals to expect strong wind gusts of up to 140km/h.

A severe weather watch was also put in place for heavy rain as the cyclone tracked down the east coast of the North Island.

Cyclone Cook left slips, fallen trees and power cuts that left many locals without electricity for days.
