The year of 2014 was in the top 10 warmest years since records began, according to Pitsford Hall weather station.
Experts at the station said the average temperature was 11.1C. For the UK, 2014 is likely to be the warmest year on record but Northampton did not set any records in the last 12 months, coming in at the ninth warmest year.
A spokesman for the centre said one notable feature of the year was the lack of frost and snow.
“Snow only fell on four days in 2014 and was never recorded as lying on the ground at 9am. This compares to 32 days in 2013 when snow fell, and 28 days when it was lying on the ground in the morning. Only 19 days recorded an air frost in 2014, compared to 59 days in 2013.
“In fact, the coldest it got was -2C on January 21. However, 2013 was much colder overall than average and with the coldest spring for 50 years,” he added.
Rainfall for 2014 was 702.1mm, little above average.
