Dublin is a city that has something to offer year-round, with plenty of events, historical monuments, and experiences. But how do you decide when the best time to visit is? 

We’ll help you explore what’s on in Dublin and help you decide the best time for your visit based on your personal preferences. Broken down season by season, let’s get into it. 

Summer in Dublin

Pros

Summer in Dublin offers the warmest weather of the year, with average temperatures ranging from 15°C to 20°C. Days are longer, with plenty of daylight, so if you like a good picnic or outdoor activities, then this is a great time. 

This is Dublin’s peak festival season. The city hosts vibrant events like the Dublin Theatre Festival, St. James’s Gate Brewery Tours, and Dublin Bay Summer Festival, so there is plenty to do.

Dublin’s nightlife is in full swing in the Summer, with outdoor pubs, live music, and jumping nightlife districts like Temple Bar attracting large and lively crowds.

Cons

Summer is Dublin’s high season, leading to crowds at popular tourist spots. Expect busy streets, longer queues at attractions, and higher hotel prices.

Winter in Dublin

Pros

Dublin is huge at Christmas time, with plenty of festive spirit thanks to Christmas markets, stunning lights around the city and of course, the fairytale-like Dublin Castle. If you love a winter celebration, this is a magical time to visit.

Flights and accommodation tend to be cheaper, especially in early winter before the immediate Christmas rush, making it a budget-friendly time for travel.

Dublin is famous for its cosy pubs with roaring fireplaces. The city’s food scene also shines during the colder months, with hearty dishes like stews and Irish breakfast.

Cons

It goes without saying that the winter temperatures are chilly, averaging 5°C to 8°C, and it’s often damp, so the weather can be uncomfortable for some.

Days are shorter, with daylight lasting only about 7-8 hours, limiting outdoor activities.

Some attractions may have reduced hours or be closed for the season, so it’s important to check schedules in advance.

Spring in Dublin

Pros

Spring offers pleasant weather with temperatures ranging from 9°C to 15°C, which, for many, will be the ‘perfect’ temperature. It’s also nowhere near as busy as Summer is, so it is a lot better for all your outdoor activities. 

One of the biggest events in Dublin, St. Patrick’s Day (March 17th), is a once-in-a-lifetime experience for many visitors.

The parks and gardens in Dublin bloom beautifully in spring, offering a picturesque setting for walks and photo ops.

Cons

Spring weather can be unpredictable, with occasional rain showers and chilly winds, so packing for all conditions is required. It can feel warm during the day but chilly in the evenings, so layering is recommended.

While not as busy as summer, St. Patrick’s Day and other spring events can draw large crowds, especially in the city centre, so time your visit if you want to avoid the crowds.

Autumn in Dublin

Pros

Early autumn offers nice temperatures ranging from 11°C to 17°C, with cooler evenings and crisp air.

As schools are in session, the city experiences fewer crowds than in the summer months, offering a more relaxed experience at the large attractions.

The parks and nearby nature spots showcase stunning autumn colours, making it a great time for scenic walks or hikes, particularly around Phoenix Park and St Stephen’s Green.

Dublin hosts events like the Dublin Fashion Festival and Dublin’s Oktoberfest, so keep a keen eye out for these.

Cons

As the season progresses, temperatures drop, looking at you November, so it can feel cold, especially in the evenings.

Like spring, autumn in Dublin can be wet, with occasional heavy rainfall. Waterproof clothing is a must.

As daylight decreases, you’ll have fewer hours to explore the city in natural light, especially later in the autumn months.

So, when is the best time to visit Dublin?
