About This Station
This weather station is powered by a Tempest home weather system, complemented by a self-built One-Wire network of additional sensors. Data is collected in near real time, with the website updated approximately every 10 seconds using Weather Display. In addition to the Tempest, the station includes a RainWise rain gauge and One-Wire sensors measuring garden and grass temperatures, night-time cloud conditions, and soil temperatures. The garden sensors are housed in a purpose-built Stevenson screen, designed to provide accurate and consistent readings. Local weather forecasts are generated using WXSim, which has been running since November 2016. Forecast accuracy is continually refined through weekly reviews of forecast errors, allowing the system to learn from previous results and improve over time. Weather data has been collected at this location since 2010. Unfortunately, a computer failure in late 2012, combined with the absence of a backup, resulted in the loss of approximately three years of historical data.

About Chelmsford
Climate
Chelmsford has a temperate maritime climate, typical of much of the UK. Its location in southeast England generally gives the area relatively mild winters, warm summers and comparatively moderate rainfall. The nearest long-established Met Office observing station is at Writtle, approximately 1 mile (1.6 km) west of Chelmsford city centre. The current climate averages are based on the 1991–2020 30-year observation period, providing a more up-to-date picture of the local climate than the previously used 1981–2010 averages. Climate at a Glance Average annual maximum temperature: 15.04°C Average annual minimum temperature: 6.27°C Air frost: 41.9 nights per year Annual sunshine: 1,594 hours Annual rainfall: 808 mm Days with 1 mm or more of rainfall: approximately 140 days per year Summer Summers in Chelmsford are generally warm, with July and August having average maximum temperatures of around 23°C. June averages 20.68°C, while September remains relatively mild at 19.71°C. The climate can, however, produce much higher temperatures during periods of exceptional heat. Historical temperature records should be considered separately from the climate averages above. Winter Winters are generally mild by UK standards, although cold spells and frosty nights still occur. January has an average maximum temperature of 7.79°C and an average minimum of 1.78°C. Across the year, Writtle averages 41.9 air-frost days, with frost most common between November and March. Rainfall The latest 1991–2020 data gives an average annual rainfall of approximately 808 mm at Writtle. Around 140 days per year record at least 1 mm of rainfall. Rainfall occurs throughout the year, although October, November and December tend to be among the wetter months. Sunshine Writtle receives approximately 1,594 hours of sunshine per year on average. July is the sunniest month, averaging around 217 hours, while December averages around 53 hours. Historical Extremes The long-term climate averages describe typical conditions rather than the limits of what is possible. Chelmsford and the surrounding area have experienced significantly higher and lower temperatures, as well as occasional heavy snowfall and rainfall events. The weather station at Chelmer Village maintains its own observations, providing an increasingly detailed local record that can be compared with these longer-term Writtle climate averages.
