Blenheim's latest weather stats losing their shine
Blenheim is slipping down the sunshine rankings, weather data shows.
Data collected by Plant & Food scientist Rob Agnew at the Grovetown Business Park show that November was the least sunny November for the past 12 years, with only 91 per cent of the average sunshine hours.
Mr Agnew has given sunshine totals comparisons several times during the year, and said yesterday the news for Blenheim only continued to get worse as the year progressed.
"Blenheim is currently only in about fifth place. Whakatane's sunshine total for 2013 is miles ahead of any other town in New Zealand."
That lack of sunshine hours affected the mean temperature figures, with November this year the warmest since November 1984, and the fifth warmest November on record for Blenheim in the past 84 years since 1930.
The main factor contributing to the warmer mean temperature in November was the overnight minimum temperatures, which were well above average, Mr Agnew said.
Overcast cloudy nights meant that the night-time temperature was warmer than it would have been with clear skies.
"The consequence of the warm temperatures is that growth of most crops is well ahead of where it would be at the end of November. The season for wine grapes is about 10-14 days ahead of 2012."
