Unsettled weather in June led to almost all stations recording above average rainfall amounts for the time of year, especially in the south. Shannon Airport experienced its wettest June since 1998, while due to thundery downpours in Belmullet on the 21st, the highest daily rainfall for the month of 34.7mm was recorded, its highest at the station for June in 25 years. Mean temperatures this month were lower than normal for June, with temperatures across the country being around 1°C below average. Shannon Airport, Valentia Observatory, Roche’s Point, Dublin Airport and Belmullet all reported their coldest June since 1972.
Almost all maximum temperatures for June were recorded on the 3rd, during the period of high pressure at the start of the month, while the majority of minimum temperatures were recorded between the 9th and 12th, when the country was affected by cool northwesterlies. The minimum air temperature of 0.5°C at Mullingar on the 10th was the lowest recorded for June in 20 years at the station, while both Valentia Observatory and Claremorris had their lowest minimum temperatures recorded since 1991, with values of 4.6°C and 1.0°C respectively. Grass minimum temperatures recorded in the Dublin area on the 10th were the lowest for June in over 40 years.
