Mourne Mountains* Weather Forecast

* The Met Office produces forecasts for designated National Parks within England, Wales and Scotland. There are no National Parks within Northern Ireland but recognising that the Mourne Mountains are a popular area of recreation within Northern Ireland, a forecast is provided for this region by the Met Office.

The Mourne Mountains are a granite mountain range in County Down, Northern Ireland. They include the highest mountains in Northern Ireland; the highest of these is Slieve Donard standing at 850 metres. The Mournes is an area of outstanding natural beauty and has been proposed as the first National Park in Northern Ireland.

This area is visited by many tourists, hill walkers, cyclists and rock climbers every year and is famously known for its 35 kilometre dry stone wall that crosses fifteen summits, constructed to define the boundaries of the 36 square kilometre area of land purchased by the Belfast Water Commissioner in the late 1800s.
