Exeter Weather

Exeter has mild wet winters, punctuated by colder spells that are usually short-lived. Summer is characterised by warm and changeable weather with hot and cooler rainy spells. Temperatures do not vary much throughout the year compared to other locations at this latitude; however, the topography of Exeter can enhance the dinural range by a couple degrees Celsius, as spots along the sheltered valley of the River Exe such as Quayside, St Thomas and Exwick see colder nights and warmer days, the only exception to this is with foggy and frosty weather in the winter during anticyclonic activity when fog can linger all day and keep daytime temperatures suppressed. Similarly, the same weather patterns can elevate the maximum daily temperatures, The hottest month is July with an average high of 21.7 °C (71.1 °F), and the coldest month is January with an average high of 8.8 °C (47.8 °F). October is the wettest month with 88.9 millimetres (3.50 in) of rain. The weather station for these reading is at Exeter Airport; adding one degree Celsius to the readings from the maximum daily temperature and deducting a degree from the overnight minima broadly covers the location disparity. It is precisely because of shelter from Dartmoor that Exeter is more frost-prone than areas to the southwest, such as Plymouth. It is also drier and warmer in the summer for the same reason. The highest recorded temperature in Exeter stands at 33.5 °C (92.3 °F) recorded in June 1976, while the lowest recorded temperature is −16.4 °C (2.5 °F) recorded in December 2010.
