Most of Ireland is now in an absolute drought situation with little substantial rain on the horizon in the foreseeable future. <\/p>\n
A climatological \u201cabsolute drought\u201d is a period of 15 or more consecutive days in which 0.2mm or less of rain falls. <\/p>\n
Met \u00c9ireann<\/a> says that 17 of its 25 stations are now in a situation of absolute drought. The only ones that aren\u2019t are all in the west and north of the State \u2013 Athenry in Co Galway, Belmullet, Newport and Claremorris in Co Mayo, Finner and Malin Head in Co Donegal, Markree Castle in Co Sligo and Valentia Observatory in Co Kerry. <\/p>\n Though these stations have not experienced drought conditions, they are all classified as having had a climatological \u201cdry spell\u201d which is defined as a period of 15 or more consecutive days with less than 1mm of rainfall. <\/p>\n In the case of Johnstown Castle in Co Wexford and Cork Airport<\/a>, the period of absolute drought has continued for 23 days and there are seven other stations at 22 days\u2019 duration. They are Casement Aerodrome, the Phoenix Park<\/a> and Dublin Airport<\/a> in Co Dublin, Oak Park in Co Carlow, Mullingar in Co Westmeath, Dunsany in Co Meath and Gurteen in Co Tipperary.<\/p>\n Met \u00c9ireann\u2019s fire weather index shows the extent to which places in the south and southeast have had no rainfall in the last month and very little is forecast for the rest of the month. Moore Park in Co Cork had 5mm on June 27th and no rain is forecast until August 1st. Similarly, Cork Airport last had 5mm of rain on June 30th and will not receive any substantial rain until August 1st. <\/p>\n Similar patterns can be seen at Johnstown Castle, Oak Park in Co Carlow and Dublin Airport. <\/p>\n This summer\u2019s absolute drought is approaching the 25 days recorded at Oak Park and Johnstown Castle during the summer of 2018. The longest absolute drought on record in the State was 33 days at Casement Aerodrome, Co Dublin, from September 3rd to October 5th, 1986.<\/p>\n
