Hi Denis, I work for the Irish Film Board. Here in Ireland, the dominant influence on the climate is the Atlantic Ocean. Consequently, Ireland does not suffer from the extremes of temperature experienced by many other countries at similar latitude so the chance of snow in December is very slim. Please see our website http://www.irishfilmboard.ie for information on various locations and studio facilities throughout the country. I would be more than happy to help you with any queries or questions you may have, just email me suzanne.murray@irishfilmboard.ie.
