Climate information of places and areas in Ireland
The climate information on this page is only brief. Specific information about weather and climate can be found on the climate pages per area or town. As for Ireland the following climate information is available:

Mayo County

Most of the depressions come via a western current from the Atlantic Ocean. Ireland is often the first country to get hit by a rainy depression. This is the reason why Ireland gets more rain than the rest of Europe. This is almost throughout the whole year. However, during the summer long lasting dry periods are not uncommon. This is caused by a high pressure area at the eastern side of Ireland. Warm and dry air comes from the south or south east and travels from France over the Channel.

The location of Ireland, west of England and west of the European mainland is responsible for strong winds. Chances of fierce winds and storms are quite high in Ireland.

Green and Gray
The western regions of Ireland are the wettest. This is the reason why nature has that impressive green colour. The contrast on gray days in combination with a little bit of sunshine is very special. During these days photographers keep on making shots inspired by the overwhelming sight of nature. However, during the winter weather can get really dreary. Sometimes the sun will not show itself for almost two weeks.

Holiday weather
Ireland is not suitable as a beach destination. The Irish waters are too cold and weather is often too instable. Whoever wants to enjoy nature or the many beautiful cities and villages can visit Ireland the whole year round. Extremes in weather are uncommon and every type of weather shows a beautiful side of this country.

More climate information
Climate figures are very useful but donít present a general impression of the climate and the eventual weather circumstances within a certain period. The figures donít always reflect the chance of wintry weather, extreme heat or hurricanes. That is why we monthly offer useful extra climate information. The information below is an average for Ireland, but it should be noted that local deviations may occur. Deviations are determined by the location you are in. North-south, inland-along the coast and your altitude.
