(from the Irish weather service - Met Eireann)
The dominant influence on Ireland's climate is the Atlantic Ocean.
Consequently, Ireland does not suffer from the extremes of temperature
experienced by many other countries at similar latitude.
Average annual temperature is about 9 °C. In the middle and east
of the country temperatures tend to be somewhat more extreme than
in other parts of the country. For example, summer mean daily maximum
is about 19 °C and winter mean daily minimum is about 2.5 °C
in these areas.

averages between 1000 and 1250 mm. In many mountainous districts rainfall
exceeds 2000mm per year. The wettest months, almost everywhere are
