Weather Overview for Killarney

Located in a valley of some of Ireland’s highest mountains; Killarney features a temperate climate with mild summers and cool winters. Similar to the remainder of Ireland and due exclusively to the moderate climate and everlasting rainfall, all regions consist of remarkable luxuriant landscape which has also given the country the name of the Emerald Isle. Consequently, Killarney always looks gorgeous in the rain and in case of an unexpected shower it’s almost certain that there will always a pub open nearby to duck into.

Because of the influence of mild south-westerly trade winds and the nearby Gulf Stream, the typical climate of Killarney is rather cool and damp for the majority of the year. The overall climate is primarily subjugated by the prevailing warm, humid winds bypassing the town from the Atlantic Ocean, creating a year round temperature that is never too cold, but never too hot.

Spring

Spring in Killarney is a very mild and also quiet time of the year. As summer can at times get overly crowded and busy, spring is an ideal time to vacation. With climates ranging between 9ºC to 13ºC, often peaking at 15ºC towards the middle of May and precipitation levels dropping excessively prior to the winter, spring is almost certainly the best time to holiday to Killarney.

Summer

The summer months, which typically start in May and conclude in the middle of September, are the warmest and driest months of all. Even though the area and some attractions (that are only open during the summertime) can get quite crowded throughout July and August, temperatures are at their highest and it is still a very pleasing time to holiday to Killarney.

Similar to many regions throughout Europe, summertime is peak season presenting some disputes if you want a little isolation.

A lot like spring, autumn is also a very enjoyable time to visit Killarney. Temperatures still pleasant and the busy crowds of summer have died down a great deal. October and November however, are the town’s wettest months with average precipitation levels sitting between 120mm to 135mm.

Winter

The winter months of Killarney are characterised by short, damp, misty days and long nights.
