Met Éireann operates two weather radars in Ireland, one at Dublin Airport and one at Shannon Airport. This radar network provides real-time rainfall information for Ireland.

The radar at Shannon Airport has had high availability for 2018 and much of 2019, with only short outages, generally for routine maintenance and scheduled during dry weather. However, there have been two more significant outages recently due to technical faults, from 1 to 14 August 2019 and 25 October to 21 November 2019. The generally high levels of availability of the Shannon radar are reflected in the table, which sets out the percentage of time it was operational during each of the months from January 2018 to October 2019.

Met Éireann works closely with the manufacturers of the Shannon radar to schedule preventative maintenance and rectify technical issues when they arise. Most recently, in January 2019, at the request of Met Éireann, a review of the Shannon radar was carried out by the radar manufacturer. Following this review, a schedule of identified maintenance tasks was carried out to reduce the risk of technical faults.

Met Éireann has commenced a procurement process for a replacement weather radar system for Shannon Airport. Additionally Met Éireann has, since 2018, Met Eireann has been actively planning a broader project to upgrade, modernise and expand the Irish weather radar network. A scoping exercise is currently underway to identify the key requirements for a five radar network.
