Ireland is famous for many things; from dramatic coastlines to stunning scenery, from social scenes and live music to literature and the arts. One thing it tends to fall short on, however, is the weather.
Defined by Spring (March, April, May), Summer (June, July, August), Autumn (September, October, November) and Winter (December, January, February), each season brings a little special something and pretty much all of them bring a good measure of rain – which Ireland is pretty famous for.
Here’s our month-by-month guide to the weather and climate in Ireland with beautiful pictures.
January is a cold month in Ireland. Thankfully, just off the back of Christmas, we all have a little extra body insulation from all that hearty food!
Temperatures in January in Ireland can range from 3°C – 7°C and oftentimes the temperature can fall below freezing. Ice and snow are not uncommon, especially at higher altitudes and in the Midlands.
There can be up to 70mm of rain on average, so remember to pack a good rain jacket and some comfortable waterproof shoes.
Similar to January, February is very cold for Ireland, and ice and snow are not uncommon. Temperatures also range on average from 3°C – 7°C and below freezing conditions are not unheard of, especially at night and dawn. February’s climate is a little less wet however with an average of 60mm.
When Spring has finally sprung in Ireland, the weather generally eases up a little. Saying that in past years Ireland has been getting warmer summers and harsher winters that often last through March (and who says global warming doesn’t exist?).
Average temperatures in Ireland in March usually range from 4°C – 10°C. The days will finally be getting longer again after the Winter months, too, with Daylight Savings taking place on 31 March 2019. This is when the clocks are turned forward by one hour, meaning sunrise and sunset are one hour later, extending daylight. On the downside, there can be up to 70mm of rainfall on average in March.
As Spring finally is in full bloom, leafy green trees and flowers grow again. The temperatures in Ireland thankfully rise to an average of 5°C – 11°C in April. Rainfall drops considerably following March, and you can only expect an average of 50mm of rainfall which isn’t too bad, considering!
The final month of Spring in Ireland is sometimes considered the best. Temperatures have risen and rainfall is at a low (for Ireland!), nature is in full bloom, and summery days aren’t that uncommon. Finally, outdoor activities are a goer again and the beach or park can often be the place to be in May.
Temperatures in Ireland in May can range from 7°C – 15°, although are often much higher (especially in this past year). Rainfall keeps at about 50mm on average for the entire month.
As Summer rears its head in Ireland, it can be quite picturesque. Outdoor excursions and day trips are all the rage and people often swim, although the sea temperature remains pretty chilly! Ireland’s climate isn’t too extreme and doesn’t change massively over the year so you can expect cold days in summer.
By now, it will be bright in the evening, well past 9pm meaning the “endless summer” atmosphere is in full swing. Temperatures in Ireland in June can range between 10°C – 17°C, although recording breaking temperatures in 2018 make us question what lies in store for next June! Rainfall averages out at about 70mm.
As Summer is on the open stretch, temperatures in Ireland in July usually range between 12°C – 19°C, it’s bright until well past the kid’s bedtime and people actually wear summer clothes, believe it or not! Rainfall is the lowest it should be for all of the Summer season, at about 50mm.
As the last month of Summer gets underway, temperatures in Ireland in August remain peaked at about 12°C – 19°C, with long days still reigning supreme. August has been known to be a particularly good month for weather in Ireland, although rainfall has been known to average around 80mm for the month.
As the temperatures slowly start to drop and the leaves start to turn gorgeous shades of red and yellow, Ireland in September can be quite picturesque. Temperatures in September in Ireland pull back to around 10°C – 17°C, but are often on the latter end of that scale, and rainfall weighs in around 60mm for the month.
October can be quite a pleasant month in Ireland. Although increasing rainfall and dropping temperatures can make it a little less favourable for outdoor pursuits, dress in weather-appropriate attire and you’re good to go! Temperatures in Ireland in October generally range from 8°C – 13°C and rainfall averages at about 80mm.
Daylight savings ends in the final week of October. This means the clocks turn back by one hour, resulting in the sun rising and setting one hour earlier.
As Autumn comes to a close and daylight starts to fade, the temperatures in Ireland drop to an average of 5°C – 10°C in November (although 2018 has had record highs). The rainfall averages at 60mm.
With Christmas looming, seasonal feels are only enhanced by the weather in Ireland. Temperatures in Ireland in December range between 5°C – 8°C whilst rainfall is at 80mm. On occasion, it has snowed around the Yuletide, but often it is cold by day and at freezing by night.
