For those toying with the idea of an autumn vacation on the Emerald Isle, you’re sure to have tonnes of questions. In this go-to guide, we cover all of your most frequently asked questions and add some insider knowledge of Ireland in autumn for good measure. 

Overview

Ireland in autumn is a sight for sore eyes. While the season may not boast the same balmy temperatures as summer, a certain warmth hangs in the air as the great outdoors come alive. 

As peak tourist season fades away, Ireland in Autumn is an ideal time to explore. The leaves turn from green to golden hues and striking reds as the days slowly begin to get shorter. Parks and tourist attractions will be quieter, and costs will generally be lower for flight tickets, hotels and attractions. 

It will also be easier to get reservations in restaurants, and the city streets will remain buzzy but not be overwhelmed by throngs of visitors. In fact, many would argue that autumn is the best time to visit Ireland. 

Temperatures

For those keen to get a deeper understanding of weather in Ireland in autumn, here we break it down, month-by-month. It’s important to remember that the weather in Ireland can vary on location.

During the months of autumn, temperatures can range greatly. In addition, your location bears a significant impact on the weather you will experience. As always, rain in Ireland is almost unavoidable, so pack wisely. Never forget a rain jacket! A sturdy pair of (broken-in) walking shoes are also advisable.

Top Attractions

Ireland in autumn is all about the great outdoors! We believe the best way to experience Ireland is by embracing its local culture on easygoing adventures. Some of our favourite spots to see during this season include:

Glendalough, County Wicklow

Nestled in the valleys of Wicklow Mountains National Park, this site is one of the most majestic in all of Ireland – and in autumn, it’s at its best! Glendalough is home to a well-preserved Medieval city and a 6th-century monastery. Follow one of the trails or enjoy a picnic surrounded by wondrous woodlands. 

Boyne Valley, County Meath

The Boyne Valley is the heartland of Ireland’s Celtic heritage. It beholds great mysticism and is the site of impressive ancient burial grounds, archaeological landscapes, and castle ruins.

Killarney National Park, County Kerry

Killarney National Park may be one of the most popular destinations in Ireland on the tourist trail, but it comes as no surprise with its outstanding beauty. In autumn, it’s at its most dramatic!

Seasonal Experiences

Some of the best seasonal experiences can be had on the Emerald Isle throughout autumn. Foodies are sure to be in over their heads with the array of food festivals to snag tickets for. 

Galway International Oyster & Seafood Festival

Taking place on the last weekend of September annually, this seafood fair is one of the best in the country. Expect oysters to make your mouth water! 

Kinsale Gourmet Festival

This October food festival is bound to get your tastebuds booming. As Kinsale in County Cork is considered the ‘gourmet food capital of Ireland’, it is safe to say you’ll leave satisfied.

Halloween in Ireland 

It may come as a surprise to many, but the festival of Halloween originates from the Irish festival of Samhain. There are tonnes of spectacular and supernatural things to do around the end of October in Ireland, from parades to spooky events – not to mention the annual Púca Festival.

Flora and fauna

Nature in Ireland is spectacular year-round, yet in autumn some of the most magnificent displays of flora and fauna come into fruition. Due to Ireland’s location along Europe’s western edge, the Emerald Isle makes a great stop-over for birds en route to the Arctic from North America.

During October, Wexford Wildfowl Reserve is the winter home to some 8,500 Greenland white-fronted geese en route – or 45% of the world’s population. Some stunning flowers and berries that bloom around autumn include the Hypericum berry and Amaranthus pendulum. 

What’s On

Ireland in autumn comes alive each year with heaps of events to sink your teeth into. Whether you’re keen to indulge in some live music or want to broaden your mind with a cultural experience, there’s so much to choose from. A few of our favourite events to add to the diary include:

Galway International Arts Festival

Founded in 1978, this is arguably Ireland’s most important cultural experience. Galway was named the European capital of culture in 2019, and its standing as a centre of creativity is recognised worldwide. Galway International Arts Festival takes place each year in September.

Electric Picnic

This is perhaps Ireland’s most coveted music and arts festival, with tickets selling out at high speed each year. World-class headliners take to its stage, and if you can snag some tickets, we promise that it won’t be a memory soon forgotten. 

Clifden Community Arts Festival

As the longest-running community arts festival in Ireland, there’s something so pure about this cultural experience alongside laid-back locals. The event lasts throughout September each year. 2021 will be its 44th year, and we have no doubt it will be one of its best.
