We’ve been to Ireland for each of its seasons. Here are the best times to witness the country’s beauty, just like we did.

Thanks to family living there, I’ve been lucky enough to visit Ireland countless times. This has given me the unique opportunity to experience the Emerald Isle in every season, from the vibrant summer festivals to the cozy winter nights by the fire.

If you’re wondering when to plan your Irish getaway, you’re in the right place! Whether chasing festivals, spring blooms, or just a bit of peace, I’ve compiled the best months to visit based on what you want to experience. 

Let’s dive in and find out when you can witness Ireland’s beauty, just like I have!

When is the best time to visit Ireland?

The best times to visit Ireland are during the shoulder seasons of spring (March to May) and autumn (September to November). During these months, visitors can enjoy milder weather, fewer crowds, and more affordable prices.

Spring is especially appealing due to its blooming landscapes and vibrant greenery, making it an ideal time for outdoor activities and sightseeing. 

Additionally, events such as St. Patrick’s Day in March and various food festivals in September add cultural richness to the experience, all without the overwhelming tourist crowds during the summer months.

At a glance, here is an overview of what to expect when visiting every season in Ireland:

Season	Weather	Crowd Level	Key Events
Spring (March to May)	Mild temperatures (average 8°C to 15°C), increasing daylight, and moderate rainfall.	Moderate; fewer crowds compared to summer.	St. Patrick’s Day (March 17), various flower festivals, and outdoor activities as nature blooms.
Summer (June to August)	Warmest season with temperatures ranging from 15°C to 22°C; long days with plenty of sunshine and the highest rainfall.	Peak season is very crowded, especially in tourist hotspots.	Numerous festivals, including the Galway International Arts Festival, Cork Midsummer Festival, and outdoor events.

Now, we’ll break down what you can look forward to each month, whether you’re seeking lively festivals, stunning natural beauty, or a quiet retreat. So, let’s dive into the months ahead and explore what each one offers.

1. January

Visiting Ireland in January means cooler temperatures and a much quieter vibe—the whole place takes a deep breath after the holiday rush. If you’re the type who likes to explore without getting elbowed by tourists, this is your time to shine! 

Now, onto packing—trust me when I say you’ll want to dress in layers! A waterproof jacket is non-negotiable. Throw in some sweaters or fleeces to stay warm, and bring comfortable walking shoes because you’ll want to roam around. 

The average temperatures hang around 3°C to 8°C (37°F to 46°F), and it might rain a bit, so pack an umbrella!

Even though January isn’t overflowing with festivals, some gems are worth checking out. For instance, the First Fortnight festival runs from January 5th to 28th, and it’s all about raising awareness for mental health through arts and culture. 

Also, if you are in Dublin between January 24th and 28th, you can catch TradFest. It’s pretty awesome, featuring over 100 artists celebrating traditional Irish music in various venues around the city.

And if you find yourself in Belfast, don’t miss the Cathedral Quarter Arts Festival. There’s also the Music For Galway Midwinter Festival, which spotlights some amazing classical tunes.

2. February

February is a time when the country slowly wakes up from winter, just as spring starts to peek around the corner. The temperatures hover between about 4°C and 10°C (39°F to 50°F), making it one of the chillier months.

When it comes to packing, think of layers: warm sweaters, comfy walking shoes for wet conditions, and cozy accessories like hats, gloves, and scarves. You’ll want to keep warm, especially when the evenings get chilly. 

Rain is a staple in Ireland, especially in February. You can expect around 70 mm of rainfall. The daylight hours are still short, but they’re starting to stretch, so you can spend more time soaking up the beautiful views and bustling city vibes.

One of the coolest things about visiting in February is the festivals! The Brigit Festival in Dublin runs from February 1st to 5th, a vibrant celebration of the Celtic goddess Brigit. It’s packed with cultural events and performances that immerse you in Irish heritage. 

And if you’re a film buff, you won’t want to miss the Dublin International Film Festival later in the month. Plus, in Cork, there’s the Take Off Festival from February 14-16, showcasing amazing dance and performance art.

3. March 

If you’re thinking about visiting Ireland in March, you’re in for a treat. It’s such a special time of the year—the air is warming up, and you can feel that spring vibe creeping in. 

When you’re packing, think practical. A good waterproof jacket will be your best friend since you never know when those showers might hit. Warm sweaters are essential, too, because the evenings can get quite chilly. 

The average temperatures are around 4°C to 12°C (or 39°F to 54°F), so it’s definitely on the cooler side. You might want to pack some layers because the weather can be unpredictable.

Of course, March is lively because of St. Patrick’s Day on the 17th! If you can be in Dublin (or anywhere in the country), you’ll experience some amazing parades and festivities that last several days.

Other festivals, like the Fingal International Festival of Voices and the Belfast Children’s Festival, feature performances for all ages—great for anyone wanting to connect with the local culture.

4. April 

There’s something magical about April in Ireland—the arrival of spring just breathes life into the landscape. You’ll find the temperatures hovering between 6°C and 15°C (43°F to 59°F), so it’s definitely mild but can still be a bit brisk in the mornings and evenings.

Let’s talk about the weather—it can be a mixed bag. One moment, you might be basking in the sun; the next, you could be dodging a rain shower. Because of that, you’ll want to come prepared. Layering is essential.

April is also buzzing with culture. For instance, check out the Catalyst International Film Festival if you are in Limerick from April 18th to 20th. It’s all about underrepresented stories in cinema—pretty powerful stuff! 

And if you’re in Galway from April 23rd to 28th, the Cúirt International Festival of Literature is an absolute must. It truly celebrates both Irish and international literature. 

And don’t forget the Waterford Festival of Food from April 19th to 21st. With over 80 events, including taste tours and workshops featuring local culinary delights, your taste buds will thank you.

5. May 

If you’re considering visiting Ireland in May, let me tell you, it’s a magical time to go! The weather is pretty mild, with temperatures hanging around 10°C to 15°C (50°F to 59°F). 

It’s perfect for spending time outdoors, whether wandering through quaint towns or soaking up the breathtaking landscapes. The days are longer, too, so you’ll have plenty of daylight to explore all those beautiful historic sites.

Now, don’t get too comfortable—there’s still a chance of rain. You might want to pack that trusty, light, waterproof jacket in your bag. But overall, the vibe is generally pleasant; it’s that lovely transition from spring to summer, so you’ll feel refreshed.

May is buzzing with festivals all across the country. For starters, there’s the Birr Festival of Music from May 2nd to 6th, where you can catch some stunning classical performances. 

Then, from May 14th to 26th, the Dublin Dance Festival takes center stage with local and international dance talents. And don’t miss the Bealtaine Fire Festival on May 11th at the Hill of Uisneach. It’s all about celebrating music, food, and fun activities. 

6. June

June is a great time to wander through lush green landscapes on those long, sunny days. The weather is just about perfect, with temperatures usually hovering around 10°C (50°F) at night and rising to 20°C (68°F) during the day. 

It’s seriously one of the best times to explore—the weather that makes you want to be outside as much as possible. The sun also sets around 10 PM, which gives you plenty of time to soak in the stunning scenery or dig into some history at the sites.

June is buzzing with festivals that’ll have you feeling the joy of Irish culture everywhere you go. You might want to check out the Forbidden Fruit Festival in Dublin from June 1-3, where you’ll catch some amazing international artists. 

Then, there’s the Cat Laughs Comedy Festival in Kilkenny from June 2-4—imagine a lineup filled with hilarious local and international comedians. 

If you love books, the Dalkey Book Festival (June 13-16) is your jam. It is also home to the Taste of Dublin, where food lovers can feast on delicious dishes crafted by top chefs.

7. July 

July offers pretty mild weather, with temperatures hovering around 15°C to 20°C (59°F to 68°F). It’s one of the warmest months here, which is nice. 

One of the best parts about going in July is the long days. You’ve got loads of daylight to soak in all the breathtaking landscapes, wander through charming towns, and check out historic sites. 

This month is also buzzing with excitement—like the Galway Arts Festival, which runs from July 14 to 27. It’s a fantastic celebration of theater, music, and visual arts, featuring a mix of local and international talent. 

Then there’s the Galway Races from July 28 to August 3, an absolute must for horse racing enthusiasts. Picture this: thrilling races, lively social events, and entertainment. 

Pro tip:
When packing for your trip, a light, waterproof jacket will serve you well—trust me on this one! Comfortable walking shoes are a must, especially if you plan on exploring the beautiful countryside or the lively streets of the cities. 

8. August

Visiting Ireland in August is such a fantastic experience! The weather is usually pretty mild, with average temperatures hovering around 15°C to 20°C (or 59°F to 68°F), which is perfect for getting outside and soaking it all in. 

When you’re packing for your trip, think about layers! You’ll want some breathable tops for the warmer days, too. Don’t skimp on comfortable walking shoes—you’ll be doing a lot of exploring! 

August is also filled with festivals celebrating Irish culture. One of the must-see events is the Puck Fair in County Kerry, running from August 10-12. It’s one of the oldest festivals in Ireland, and you can expect loads of street entertainment and music.

There’s the Rose of Tralee International Festival from August 18-22. It’s such a fun time with cultural performances and a parade. And don’t forget about the Fleadh Cheoil na hÉireann, a major traditional music festival from August 6-14 in Mullingar. 

9. September 

September is one of my favorite times to visit Ireland. There’s just something magical about that month, right? The country is starting to wake up from the summer slumber as we transition into autumn. 

The temperatures are usually pretty mild, hanging around 10°C to 17°C (50°F to 63°F). But be prepared; the weather can be a bit unpredictable. You might experience those stunning sunny days, but there’s also a chance of a rain shower.

One of the best parts of September is how the landscapes transform. You can see the color shift as the leaves start to change, especially in the national parks and rural areas. It’s like nature’s version of Taylor Swift’s Evermore era, right? 

Plus, because it’s not peak tourist season anymore, you get to explore the great sights, like the Cliffs of Moher or Killarney National Park, without feeling swamped by crowds. It makes everything feel a bit more personal.

There’s so much happening in September that you can dive into the vibrant culture of Ireland. For instance, have you ever heard of the Electric Picnic? This amazing music festival in County Laois attracts thousands of folks each year. 

Then there’s the Galway International Oyster and Seafood Festival at the end of the month. It’s all about celebrating local cuisine with competitions and tastings that showcase Ireland’s fantastic seafood. 

Comfortable walking shoes are essential—there’s much to explore, from charming little towns to breathtaking landscapes. I recommend packing a mix of short-sleeve and long-sleeve shirts so you can stay cozy no matter what the day brings.

10. October 

In October, the country gets a cozy autumn makeover, with vibrant festivals and landscapes turning into stunning canvasses of amber and gold. 

The temperatures hover around 8°C to 14°C (46°F to 57°F), so it’s cool but still lovely enough to explore. Walking through those fall foliage-filled streets feels magical, especially as the summer crowds have thinned out. 

One of the coolest things about October is all the festivals happening around the country. Have you ever heard of the Guinness Cork Jazz Festival? It’s from October 24th to 28th, drawing jazz lovers from everywhere! 

And if you’re into literature, the Bram Stoker Festival happens in Dublin around the same time (October 25th to 28th), and it’s a tribute to the guy who wrote Dracula. You’ll enjoy theatrical performances and Gothic-themed events.

And let’s not forget Halloween! Ireland starts the spooky season in style, especially in Derry, which hosts Europe’s largest Halloween celebration. You’ll find parades that are part fun, part a nod to ancient traditions—something you want to see.

11. November

Visiting Ireland in November is unlike the bustling summer crowds; instead, you get this cozy vibe with the cooler temperatures. We’re talking averaging around 5°C to 10°C (41°F to 50°F), so pack for some chill. 

Don’t forget a scarf and gloves; they’ve been lifesavers while I enjoyed the sights. An umbrella or raincoat is also a smart addition to your packing list – you’ll thank yourself later.

You should expect rain – Ireland, after all! It can be quite damp, especially as the month drags on and the days get shorter. But don’t let that dampen your spirits because November is vibrant. 

Some fantastic festivals are happening, like the Cork International Film Festival from November 4th to 13th. If you’re into music, the Ennis Trad Festival runs from the 10th to the 14th, and it’s all about traditional Irish tunes! 

Also, don’t miss the Galway Christmas Market, which opens in mid-November; it’s a great way to soak up some festive cheer.

Early November still has some gorgeous autumn colors. While spending all your time outdoors is tempting, embrace those indoor activities too. The pubs are super inviting! You can curl up with a drink and enjoy some traditional Irish music.

12. December 

Visiting Ireland in December is like stepping into a cozy holiday postcard. Picture this: the air is crisp and chilly, with temperatures around 4°C to 8°C (39°F to 46°F) during the day. It can feel slightly nippy at night, dropping to about 3°C (37°F) in some places. 

You can expect about 12 cm (5 inches) of rainfall spread over 18 days. So, you should bring a good waterproof jacket because you never know when a little shower will sneak up on you. 

But don’t let that dampen your spirits! There’s something about the rain that adds to the charm of Ireland, especially when you find shelter in a cozy café or pub.

You’ll want to maximize your time with only 7-8 hours of daylight daily. Early evenings are magical, though, with towns and cities decked out in Christmas lights, creating a festive atmosphere that’s hard to resist. 

The local Christmas markets are filled with unique crafts and festive bites—think warm drinks, local treats, and maybe even live music adding to the cheer. The Dublin Castle Christmas Market is a must-see if you’re around!

You can dive into the Irish culture during this time, too. Grab a pint and enjoy a traditional music session in a local pub. And don’t skip out on trying dishes like hearty Irish stew and the classic Christmas pudding for dessert.
