The following are the five highest sources of income:

UV Sensor

The UV Index sensor at Maison St. Louis Observatory failed in May 2021 and a replacement was sourced, however, upon installation a fault was discovered.

Both sensors were returned to the supplier for repair / replacement and evaluation and have now arrived back in Jersey.

However, the new sensor required that we make programming changes to our automatic weather station program, which involved working with the manufacturer and supplier, and it has therefore taken longer than expected for the data to return online.

Once testing and verification of the output is complete, which we anticipate will be in the near future, the data will be returned to the ‘Live Weather Observations’ page of  


The main live wind sensor, which is located at St Helier’s Harbour, is currently working and has a reliability greater than 99%.

The other wind sensors are not considered a core service and will soon be removed from the live data page.

However, data from the Les Minquiers sensors are due to come back online after programmed maintenance later in 2022.
