Ireland’s changeable weather

For 12 years, off and on, I have been a stu­dent of Irish weath­er. I have stud­ied the dai­ly weath­er maps in the Irish Times. I have lis­tened to the 6 o’clock ship­ping fore­casts on the BBC. I have watched the barom­e­ter. I have held a moist­ened fin­ger to the wind.

What have I learned?

That two fore­casts will serve for 80 per­cent of the time: “Wet almost every­where with sun­ny inter­vals,” and “Most­ly dry with occa­sion­al showers.”

The remain­ing 20 per­cent of Irish weath­er includes win­ter gales that blow from Ice­land with a force that with­ers trees and rat­tles the tiles on the roof, and sum­mer anti­cy­clones that drift up from the Azores and sit for days upon Ire­land like sun­ny crowns.

Three words sum­ma­rize Irish weath­er: change­able, mild and moist.

Atlantic generator

Ire­land’s weath­er comes off the Atlantic. It is a rare wind that makes its way across the Irish Sea from Britain. The weath­er maps pub­lished dai­ly by the Irish Mete­o­ro­log­i­cal Office show Ire­land up against the right-hand mar­gin, and we can only assume that what­ev­er hap­pens east of Howth Head is usu­al­ly irrel­e­vant. On the left mar­gin of the maps is Labrador. The blank space in between is the North Atlantic, a noto­ri­ous weath­er generator.

In that wet are­na south of Green­land, cool air from the Arc­tic and trop­i­cal air from Bermu­da are in con­stant con­flict. When these unsta­ble air mass­es col­lide, they gen­er­ate depres­sion after depres­sion that are hurled east­ward toward Ireland.

It is not unusu­al for two fronts to pass across the coun­try in a sin­gle day. A day that begins in mist and driz­zle can end in bril­liant sun­shine. A day that begins fine can end with a gale. The only way to tell what the weath­er will be like tomor­row is to look out the win­dow when you wake up.

Ire­land is warmed by the Gulf Stream, a riv­er in the ocean that car­ries the heat of Mex­i­co 4000 miles north and east to the shores of Europe. The coun­try is at the lat­i­tude of Labrador, but its win­ter cli­mate is milder than New Eng­land’s. Enough snow to be a nui­sance is rare in Dublin and unheard of in the south­west. Palm trees grow in Cork and Ker­ry, and fuch­sia, an import from more equa­to­r­i­al lat­i­tudes, runs wild like a weed.

At the oth­er extreme, tem­per­a­tures of 70 degrees Fahren­heit are a heat wave, and cause for com­ment in the papers. This year it was 70 degrees at East­er, and Irish peo­ple who went to the Mediter­ranean for the sun would have done bet­ter to have stayed at home.

The ther­mal mass of the sur­round­ing seas stead­ies Ire­land’s cli­mate. The vari­a­tion in aver­age tem­per­a­tures through­out the year is only 15 degrees. But mov­ing air can add pleas­ant or unpleas­ant fluc­tu­a­tions to the gen­tly undu­lat­ing curve of tem­per­a­ture; I have gone swim­ming on Ker­ry beach­es in Jan­u­ary and piled on sweaters in July.

Irish mist

And wet! Cer­tain moist themes in the weath­er fore­casts are as Irish as sham­rocks. “Driz­zle spread­ing from the west will affect all areas by morn­ing.” Not as much rain falls in Ire­land as some peo­ple think. A drench­ing down­pour is uncom­mon. It is the fre­quen­cy and per­sis­tence of the rain that is unique­ly Irish. It hangs in the air. It sits in the bogs. It squish­es up around your boots. It creeps in across the win­dow jambs and under the door. Some­times it seems as if the whole coun­try has been turned upside down and the sea is on top. Ire­land faces into the Atlantic like the prow of Europe — and catch­es all of the spray. It is no acci­dent that the nation­al liqueur is called Irish mist.

Tourists some­times grum­ble about the Irish weath­er, but natives nev­er do. Irish peo­ple talk about the weath­er, some­one said, with “qui­et res­ig­na­tion and grat­i­tude.” It is a rare day that does not have its moment of spe­cial beauty.

In Ker­ry, they say that the peak of Car­ran­tuo­hill, Ire­land’s high­est moun­tain, was the last dry land to stand above the ris­ing waters of the bib­li­cal Del­uge. As Noah steered his ark past this tem­po­rary island he saw upon it a Ker­ry­man, who greet­ed him with the uni­ver­sal Irish greet­ing: “A fine soft day, thanks be to God.”
