Ireland's climate is surprisingly mild given its northern location. This is mainly due to the warming effects of the Gulf Stream which brings warm waters up to Western Europe from the more tropical Atlantic zones.
Temperamental is a fitting description of Ireland's weather. It can be very unpredictable! The old adage that it is possible to experience four seasons in one day is close to the truth. During the summertime, the warmest months tend to be July and August, when average temperatures during the day can range from 15ºC to 20ºC. A hot day in summertime could produce temperatures of 22ºC to 24ºC and on rare occasions can exceed 30ºC.
The best time to travel to Ireland for an outdoor trip such as a bicycle tour is from the beginning of May to the end of September. April and October are also possible, but the chances of encountering inclement weather increase. Towards the end of October the days are significantly shorter.
Traditionally May can provide some of the best weather days of the season. The last two weeks in June have the longest days of the year.
July and August are peak travel season for Ireland. The first weekend in August (a public holiday weekend) is the busiest of the season. School holidays are from the end of June until the end of August.
The latter half of September sees the change to autumn colours.
