St Denys Weather Previous Temperature and Humidity Measurements

NB this page describes the station in use until 25th July 2018

The main part of the weather station (see photo) consists of a black cylindrical rain collector below which is a stack of white “plates” which form a “radiation shield” for the temperature and humidity sensors – it stops them getting heated up in the sun. The white box to the right of the rain collector houses the electronics and the radio transmitter which sends the data back to the house. Situated at the end of the jetty, the sensors are well exposed to the surrounding air and normally should give accurate readings. However remember that they are over the river. In some circumstances (e.g. a calm, frosty night) conditions over the river may be different from over the land even just onshore.
