A database of Ireland mountains. You can join for free and access reviews, maps and walks along with loads of information on Irelands mountains built as a hillwalkers resource to the Irish mountains.
Set to the Leinster weather page.
Another very good weather site primarily for sea activities but quite accurate. Type in your nearest location for your walk, l have set this link to Brittas Bay County Wicklow.
