Posted in: Blogs, Activity, Guides, Ireland

Ireland, also known as the Emerald Isle, is a country you can enjoy throughout the year. There are countless fantastic activities and sights to see and do, so depending on your interests or your available time to come, we have you covered with this useful guide.

Planning a tour of Ireland can depend on so many factors. Maybe you’ve already booked vacation time and are looking for the best thing to do in Ireland at that time. Perhaps you’re thinking of a road trip in Ireland for your next holiday and need some inspiration.

Read on to learn all about the best time to visit Ireland.

When is peak season?

Ireland is a year-round destination due to its temperate climate and beautiful sights. It is, however, the summer that attracts the most visitors. Open season for a lot of accommodation and attractions is usually from April until September.

The busiest months are July and August, where you may find yourself sharing attractions with many other visitors. The months that shoulder the summer are also popular as you can enjoy some nice weather paired with a lower visitor footfall.

Another period that sees a lot of international visitors is mid-March. Dublin is very busy around this time of year as it coincides with the ever-popular St Patrick’s Day celebrations.

When is best for weather in Ireland?

The best time to visit Ireland for the weather is definitely during the spring and summer.

The summer is indeed the warmest and driest season. Between May and September, you can take advantage of warm summer temperatures (or warm for here anyway!) and longer daylight hours for the best sightseeing.

It’s good to keep in mind that, like many northern Europe countries, Ireland is rainy all year long. It is not such a green country for nothing! As the weather is pretty changeable, you may find you encounter rain, sunshine and wind all within one day. It is part of the experience and charm of Ireland!

Be prepared and you won’t miss a single thing. This is why we recommend always having a few layers with you, especially windproof and rainproof layers. Check out our Ireland packing guide for more information.

The weather is also slightly dependent on where you are visiting. Generally, the west coast is windier as it is exposed to the Atlantic Ocean, and the southeast gets the best weather.

Which month is best to explore Ireland?

While the weather may be a big draw for some, you may want to come to Ireland for a particular month or season, whether that’s when you have holidays or when you want to enjoy a certain activity.

Exploring Ireland in summer

One of the best times to visit Ireland is during the summer. You’ll enjoy warmer weather, ranging between 13°C and 18°C (55°F-64°F) and longer daylight hours to take advantage of all the summer activities, festivals, and attractions.

Ireland is truly booming during that time of year, offering you plenty to do and see.

Summer is also the perfect season to drive around the country. Enjoy a safe and convenient road trip around Ireland with longer daylight hours giving you more time for sightseeing.

If you want to visit the remote Aran Islands or even Skellig Michael, the summer is the time to plan your visit. Boating trips are often only available during the high season, and are always dependent on weather and sea conditions.

To make the most out of your visit, especially if you intend to go to a lot of attractions, we recommend you plan your trip between April and September. Places such as museums, distilleries and historic sites often have restricted hours during the winter. Some are closed completely after October.

One thing you should consider when planning to explore Ireland is how popular the country is during the 'peak season'. Between June and August, the country is abuzz with visitors from around the world.

For that reason, we recommend the shoulder months. April-May and September-October still features nice weather and has fewer visitors as well. Those months are ideal if you are looking for a quieter vacation.

Exploring Ireland in winter

Winter in Ireland roughly extends from October until March. Thankfully, because of the island's location, right in the path of the Gulf Stream, local temperatures do not dip too much during this time. The average temperature is between 4°C and 8°C (39°F-47°F).

Irish winter is a season characterised by wind and rain. You’ll also find that it rarely snows in Ireland. However, you may find some snow up in the mountainous regions, which receive around 30 days of snow a year.

Travelling during the 'off season' has its advantages. While the shorter daylight hours may mean you have less time during the day to visit and see the sights, you’ll enjoy uninterrupted sweeping views and smaller crowds. You may even find you have some sites to yourself!

The great thing about Ireland is that since it doesn’t get too cold during the winter, you can still experience all the famous sights. Don’t let the weather stop you! You may even really enjoy the different perspective and lovely soft light that winter casts on the Irish landscape.

If you want to experience the local culture, you may really enjoy visiting Ireland during the winter. It’s the ideal time of the year to curl up in a warm pub with a glass of whiskey listening to traditional music. Get a taste of the local food and drink and experience the warm Irish hospitality.

The downside of travelling to Ireland during the winter is that, despite being a year-round destination, there are fewer activities available at that time of year. Be aware that some top attractions have restricted opening hours, or are closed for the winter.

When is best to explore Ireland for…

There are truly no bad times to visit Ireland. To help you plan your dream trip we’ve compiled the most requested interests and activities and when is the best time of the year to come to Ireland for them. Look up the one you’d love to experience while in Ireland:

Wildlife watchers

Avid wildlife watchers will have much to spot while touring the Emerald Isle!

Birds

Ireland welcomes more than 250 migratory birds to its shores, in addition to more than 100 local species. These bird species include puffins, guillemots, cormorants and gannets – colonies are especially present on the west coast.

The Cliffs of Moher are a Special Protected Area according to Irish and EU regulations. This declaration was made because of the 20 species of seabirds found here.

If you’re visiting this iconic Irish attraction, you’ll want to look out for a huge range of birds, including:

  • Guillemots
  • Razorbills
  • Kittiwakes
  • Peregrine falcons
  • Puffins.

Some of the species are present here all year long, but the best time to spot them is between April and July.

Sea life

The coast is also a good location to go in search of the marine life surrounding Ireland. There are plenty of fish (and other species) in the sea! This is important as fishing is an important national industry.

To spot some of the best sea life, make sure to take advantage of the Wild Atlantic Way. From Malin Head down the west coast to County Cork. Stop by the water to try to spot animals including whales, dolphins, and otters.

Summer is the best time to try to catch a glimpse of the different types of whale.

If you’re a fan of seals, you’re also in for a treat. Common seal pups are born in the spring around May. You may be able to get a look at grey seal pups later in the year as they are usually born around September.

Wildlife enthusiasts may want to make sure to bring their binoculars and camera to capture it all!

Photographers

Photographers will have the time of their life in Ireland. The dramatic coastal sights (especially on the west coast) will make you want to take your camera out!

We recommend the shoulder months of April and October as the popular attractions and scenic locations will be far less crowded.

Because of the country’s northerly latitude, the days are shorter in October. This means the sun does not rise too far above the horizon, which produces a very special light for photography.

While the weather may be more changeable at this time of year, you may find the occasional storms coming in from the Atlantic a real treat. They can produce powerful images of dramatic skies and waves crashing on to the rugged coastline.

A bonus is the sunsets. They are often a highlight for photographing the Atlantic coast, and during this time of year can be enjoyed at a more convenient time of the day. This is in contrast with the summer when sunsets occur late at night.

One of my favourites is the Dingle Peninsula with its narrow, twisting roads, miles of golden beaches, jagged coastal cliffs and green, sheep-filled pastures backed by mountains – a photographer’s dream!

Hikers

Ireland is a beauty for hikers and definitely worth the effort! You’ll want to walk along the high coastal cliffs and see the sweeping views from the hilltops.

While Ireland rarely gets too hot or too cold to go for a hill walk or a good hike, you’ll want to visit during the April to September period to enjoy this activity.

During spring, summer and autumn, the temperatures are comfortable for you to enjoy a half or full-day hike.

More specifically, the beginning and late summer is probably the ideal time for hikers to visit and be able to take full advantage of Ireland’s beauty.

During this time of year, the trails are most accessible and less crowded. The longer daylight hours mean you can take advantage of your days (morning or evening) even more.

In the spring and autumn, you may enjoy the mild weather for a day of physical activity. However, you may find it a bit windy and the weather more changeable. Be prepared and you’ll surely enjoy the hike and stunning views!

At any time of the year, we recommend being prepared for any weather, especially if you are by the sea or high up the mountains. Ensure to bring layers, light, warm and waterproof, and to stay hydrated!

Whiskey lovers

Ireland is an ideal country to visit if you enjoy a good whiskey! There’s never a bad time of year to enjoy a glass of fine locally distilled whiskey.

In the winter, you may particularly enjoy finding a spot amongst the locals in a cosy pub. Warm up with a glass of the ‘water of life’, as they call it in Ireland.

You may also enjoy visiting a distillery to see just how your the national spirit is made. You’ll have a world of choice, with our favourites being the Old Jameson distilleries in Dublin and County Cork, Old Bushmills in Northern Ireland, and the Kilbeggan distillery in the Midlands.

Many distilleries are open all year long, though they may operate with restricted opening hours during the winter.

Castle explorers

Ireland’s rich history makes it an ideal place to visit for castle enthusiasts. Dotted around the country, you’ll find castles, estates and mansions. Many are open to the public, with guided or self-guided tours. Come learn about Irish history, or to see how the other half used to live.

If you want to visit the many castles of Ireland, we recommend visiting between the spring and autumn.

While most castles are open all year long, some operate restricted hours over the winter or may be closed completely. It is also good to note that most attractions are closed during the Christmas period.

Depending on the location, if you’re adamant on visiting it, make sure to check their specific opening hours and plan your trip accordingly.

To visit in a quieter time, we recommend the shoulder season, just before or after the summer. This is because, at the height of summer, it may be quite busy to visit popular attractions.

If you are here during this time, we recommend visiting early or later in the day to avoid the crowds.

Families

Ireland is a great country to visit with the whole family. There is plenty of attractions that will please both adults and children.

Your decision of when to visit Ireland with your children may depend on many factors. Have you already booked to come during the summer school holidays? Do you want to experience a particular activity with them? For this, look up our above categories to get a better idea.

For families, we would usually recommend a slow-paced summer self-drive tour. This would allow you to stop longer in some locations, giving you flexibility on what and when to visit attractions.

During this time, there are plenty of attractions open that kids will love to discover. From castles where they can dress up as knights, to modelled villages to experience the ancient rural Irish life.

The summer also has some more daylight hours to take advantage of for sightseeing. That is also the least rainy time of the year when your kids will be able to enjoy the outdoors.

July and August are two busy months in Ireland. To have a quieter holiday during which your children can run freely, we suggest visiting in June.

We would advise to also keep in mind, while you're planning your family trip to Ireland, that young visitors may not be allowed into whisky distilleries for tours and that the minimum age for drinking in Ireland is 18.

Honeymooners

If you’ve always dreamed of a honeymoon in Ireland, the best time to come may depend on what you want out of it. Only you can answer that question, but we’re here to help!

Do you want to drive the iconic Ring of Kerry? Summer or autumn.

Are you intent on seeing the island where recent Star Wars movies were filmed, Skellig Michael? Summer.

Or maybe your goal is to see the top highlights without crowds, in peace? Winter.

In the summer, you may enjoy the longer daylight hours to sightsee. You’ll also be able to take advantage of the nicer weather to enjoy time outdoors together. Have a romantic picnic on a white sand beach or walk lavish estate gardens.

Wintertime is also a romantic time of the year to visit with your new life partner. Why not curl up with a pint in front of a fireplace in a Galway pub, listening to the traditional Irish music?

With fewer crowds at this time of year, you may find you’re spending more quality time together at each highlight. We also recommend a slow-paced tour with longer stops at each location to enjoy a leisurely time together.

Events and festivals

The Irish are renown worldwide for their festivities, making Ireland a great place to visit if you love attending events and festivals. There is a bit of everything for everyone, with festivals and events on all kinds of subjects, such as:

  • Film
  • Art
  • Theatre
  • Literature
  • Seafood
  • Irish history.

Whether you’re here in mid-July or mid-January, you’ll always find some fun events to join in. However, summer is the busiest time with events held in towns and cities all over the country.

To mark the New Year, you may want to stay in Dublin. The city hosts a New Year’s Festival with not one, not two, but three countdown events to mark the occasion! On the first of the year, continue the celebrations at the family-friendly New Year’s Day concert. And it’s free to boot!

Later in January, Dublin is also the host of TradFest. Today it is the largest festival of traditional music in Ireland! If you love folk music, you’ll definitely enjoy this showcase of the best of Irish and international trad music.

In late February- early March, catch an interesting new film at the Dublin International Film Festival.

Many true Irish descendants may know that March marks the celebrations of St Patrick’s Day. Coming at that time of year will be a busy affair!

Especially in Dublin, where the city hosts a five-day festival to the nation’s patron saint. The celebration concludes with the parade on the 17th (the actual St Patrick’s Day).

During the summer, you’ll find a host of activities and events throughout the country. Two big ones to add to your diary are the Seafest at the Cork City Quays in June and the Galway International Arts Festival in late July.

September is another busy month on the Irish social calendar. Galway hosts the International Oyster & Seafood festival for those who want to sink their teeth into some delicious local food. Dingle has its very own version of Tradfest and Dublin hosts the Fringe Festival.

You’ll enjoy a spooky October if you love vampires and literature as Dublin hosts the Bram Stoker Festival.


Only you can truly decide which time is best for you to visit Ireland! Every month in this superb country offers great travel experiences, so we hope this guide helps you to choose with confidence.
