MetOcean smart buoys – remote insight into weather and sea state conditions

A selection of our lighthouses and buoys are equipped with meteorological and oceanographic (MetOcean) sensors and transmit their data to Irish Lights HQ. 

We currently have a number of buoys and lighthouses collecting weather and sea state data.   Measurements include average wind speed, wind gust speed, average wind direction, gust direction, wave height, wave period and water temperature.   Values are posted on Twitter every 20 minutes. 

This data is transmitted to our HQ via the Automatic Identification System (AIS) radio based communication network. The data for each location is published via an automated Twitter feed after some formatting. The MetOcean data can be stored, analysed, graphed via our MetOcean site. 

For all queries or to provide feedback on the MetOcean service please email info@irishlights.ie
