Spring in Dublin

Spring in Dublin is generally lovely—the days get longer, flowers bloom, and a certain post-winter energy is in the air. March can still be chilly and wet, but the weather is crisp, pleasant, and moderate overall. Spending spring in the city means you’ll experience fewer crowds and lower prices.

March sees average highs of 50°F (10°C) and lows of about 37°F (3°C). Temperatures gradually increase, with May experiencing highs of about 59°F (15°C) and lows of 43°F (6°C).

A national holiday and Ireland’s biggest event of the year, St. Patrick’s Day falls on the 17th of March. This festival sees hundreds of thousands of people flock to Dublin’s streets to join in the celebrations. 

If you’re planning a trip to Dublin over this period, remember that St. Patrick’s Day festivities usually happen from the 15th to the 19th of March. Due to the large crowds, accommodation during this time becomes expensive and fills up quickly.

Apart from St. Patrick’s Day, March through May tend to be quieter shoulder-season months. You’re more likely to get deals on airfare and hotels during this time. The bonus of visiting in the spring is that April and May see primarily clear weather, with April being the sunniest month with the least rain.

Spring Travel Tip: The Easter Holidays also tend to be a busy time in Dublin. Keep this in mind when booking your trip. 

Summer in Dublin

Summer is the perfect time to explore Dublin’s outdoor activities, such as music festivals, city tours, river cruises, and drinking ice-cold Guinness in the sun. Dublin summers are generally crisp and mild, although that’s not to say that Dublin can experience sudden heat waves or heavy rainfalls during this time. 

June temperatures in Dublin can range from highs of 64°F (18°C) to lows of 48°F (9°C). In addition, July and August are the warmest months, with temperatures in the day averaging around 68°F (20°C) and at night about a cool 52°F (11°C). You can enjoy around 16−17 hours of daylight in the summertime, making it ideal for outdoor activities like going on a sightseeing cruise.

That said, Dublin gets so busy in summer, so consider trying less-touristy activities that will be manageable with crowds; spend the afternoon in Iveagh Gardens, discover the city’s hidden speakeasy bars such as the Blind Pig, or walk the coastal Great South Wall to get an alternative view of Dublin.

Summer is also a perfect time to try one of the city’s hop-on-hop-off open-top bus tours, a flexible way to cover more ground in less time. You can also try a Dublin boat tour if you are up for a maritime adventure.

Summer Travel Tip: Summer is the peak tourist season in Ireland. If you plan on visiting Dublin during this time, book your flights, accommodation, and tours well in advance (at least six months). This can help you save quite a bit of cash.

The city is arguably at its prettiest in the fall—when green summer hues change to shades of red, brown, and golden orange. This time of year is the low season for tourists. You can enjoy the city more freely without the masses of people and look forward to less competitive prices when it comes to accommodation and going out.

When it comes to Dublin in September, temperatures are pleasantly moderate, with average highs of 63°F (17°C) and lows of 48°F (9°C).

Dublin City is full of medieval history and stories, so get into the swing of Halloween and sign up for a haunted city tour. You’ll learn a lot about the eerie spooks of the city, and many people report having experienced chilling sensations as if they were in the presence of ghosts. 

Prefer something a bit less spooky? Visit the National Botanic Garden to witness the fall colors in full force. If you’re in Dublin in November, visit Ice Skating Blanchardstown—the country’s largest ice skating rink.

Although there won’t be as much dining and merrymaking outside as in the summer, fall in Dublin provides an excellent opportunity for a cozy, intimate, and budget-friendly getaway.

Fall Travel Tip: Even though temperatures can be cold in the fall, Ireland is a place where you can experience all four seasons in one day. Make sure to bring a rain jacket or umbrella. Wearing layers is particularly useful, so you can remove some clothes if it gets a bit warmer in the day.

Winter in Dublin

Winter in Dublin, Ireland, is something straight out of a fairytale. Cozy and romantic. There’s a unique festive energy in the air. If you love all things Christmas, December is a perfect time for you to visit. 

However, remember that Dublin winters see the most rainfall out of any other season, and days are at their shortest with temperatures at their lowest. So it helps to be fully prepared—umbrellas, raincoats, and all.

Dublin in December, January, and February can get very cold. December has average highs of 48°F (9°C) and lows of 37°C (3°C). The coldest months of the year are January and February, where average temperatures fall between 39.2°F and 44.6 °F. Temperatures during this time can quickly drop below freezing, and yes, it can most certainly snow in Dublin.

Winter is a great time to book the Dublin Castle tour, as there’ll be fewer crowds. There’s also a certain magic about exploring medieval castles under gloomy, gray skies. 

During this time, you can take shelter from the cold in peaceful galleries and museums. Enjoy a pint by the fire in one of Dublin’s many cozy Irish pubs. Explore the Christmas markets and witness the city illuminated by light shows and lantern sculptures. Guaranteed to warm you up quickly, go on the Teeling Whiskey Distillery tour.

Winter is also the perfect time to see some gigs—Dublin is renowned for its world-class live music scene. Check what shows are on at the National Concert Music Hall—otherwise known as the ‘home of music in Ireland’.

January and February are quiet tourist months, where you can stroll around freely and not have to plan your days in Dublin so far in advance. Around Christmas and New Year, there will be an increase in crowds, prices, and accommodation. However, the rest of winter is quiet and relaxed.

Winter Travel Tip: These cold and frosty months are the perfect time to try Dublin’s traditional Irish stew—a delicious, filling, and hearty mix of lamb, potatoes, carrots, and onions.
