The Irish Marine Weather Buoy Network is a joint project designed to improve weather forecasts and safety at sea around Ireland. The buoy network provides vital data for weather forecasts, shipping bulletins, gale and swell warnings as well as data for general public information and research. Buoy data is also helpful for validating our operational models.

The project is the result of successful collaboration between the Marine Institute, Met Eireann, The UK Met Office and the Irish Department of Transport.

Current Issues:
Buoy M6 is out of service. The Celtic Explorer successfully recovered the M6 Met Buoy 30th January 2014 in difficult weather conditions. The buoy had broken its moorings early January following extreme weather conditions but continued to transmit its position and weather data. We had closely monitored its position waiting for an opportunity to safely recover it

It was successfully recovered about 40- 50 miles west of the Skelligs by the crew of the RV Celtic Explorer with the assistance of the Irish Whale and Dolphin Group who had been surveying onboard the Explorer. It will be redeployed in April from the Celtic Explorer on transit to Newfoundland and Labrador. 

Buoy M3 is back in service - 11th March, 2014 

This infrastructure has been part funded under the Marine RTDI Measure of the National Development Plan 2000-2006, co-funded by the European Regional Development Fund (ERDF).
