Northampton Weather

As with the rest of the British Isles, Northampton experiences a maritime climate with cool summers and mild winters. The official Met Office weather station for Northampton is the Moulton Park Weather Station at the University of Northampton. Situated at an elevation of around 130 m (427 ft) above sea level compared to Northampton town centre at 50 to 60 m (164 to 197 ft), it is one of the highest points in the Borough, and so may not be a perfect representation of other parts of the town. Its hilltop location means less pooling of cold air on calm clear nights, and lower maxima during summer. The absolute maximum recorded is 34.7 °C (94.5 °F) on 3 August 1990. A high of 34.4 °C (93.9 °F) was recorded on 19 July 2006. The absolute minimum is −16.8 °C (1.8 °F), recorded during February 1986. It is likely the absolute maximum in the town centre is a degree or so higher owing to the lower elevation, and absolute minimum on the eastern and western edges of the Borough around the Nene valley a couple of degrees colder due to katabatic drainage of cold air allowing a frost hollow effect. Most recently, the temperature fell to −9.6 °C (14.7 °F) on 20 December 2010.

Rainfall, at around 650 mm (26 in) per year is not high, though is often unpredictable, giving rise to flooding events such as 1998, but also short term droughts. Desborough Weather Station also supplies the public with a local weather service.
