Last year was warmer and sunnier than average in most of the country, with rainfall close to normal, according to figures released today by Met Éireann.

Annual mean temperatures were above average for the eleventh successive year, ranging between 10 and 11°C. This is around half a degree over normal. Average temperatures are measured against records taken between 1962 and 1990.

There was above average sunshine, although last year failed to surpass 2003's record levels. February and March last year were exceptionally sunny, with some areas reporting record occurrences. However, the whole month of November was extremely dull.

The sunniest day was on June 15th, with Cork Airport recording 16 hours of sunshine. This was the highest daily value recorded by the weather station at the airport since it opened in 1962.

The heaviest rainfalls of the year happened in the second half of October. The storms of October 27th/28th, when up to 150 millimetres of rain fell in 48 hours, lead to severe flooding in the south and southeast.
