Best Time to Visit Dublin
The best time to go to Dublin: The best time to go to Dublin is when the weather is at its warmest, June through August, with the high average temperature in the upper teens. The summer season brings more sunny days, but it’s important to keep in mind that rain is always a possibility, prices will be higher, and lines will be longer. Visiting in April or May when the spring weather has arrived while crowds are still manageable, or from mid-September through mid-October, before chilly temperatures return and crowds have diminished, are also good periods to visit Dublin.
Best Time for Sightseeing: The best time for sightseeing in Dublin is when temperatures are comfortable, but lines aren’t as long and crowds not as thick as summer, generally the month of May or from mid-September to about mid-October. As rain can occur at any time in Ireland, be prepared by bringing a waterproof jacket and umbrella for those inevitable showers.
Best Time to Visit for Weather: The weather will be warmest in the summer in Dublin, with July seeing the least amount of precipitation of the season, making it the best month for limited rain. It’s unlikely to feel hot with temperatures mild compared to most major cities, typically in the upper teens and occasionally reaching the low 20s. The peak of summer is a great time for hiking in the mountains, spending time on the beaches and enjoying lively festivals. The days are quite long, making it easy to take in more outdoor attractions with nearly 17 hours of daylight on July 1.
Best Time to Visit Dublin for Shopping: For those who want to enjoy bargain shopping on Dublin’s famous shopping streets like O’Connell and Grafton, the biggest sales come just after Christmas. In recent years they’ve begun as early as December 26, St. Stephen’s Day, when items are discounted as much as 60% off, and run through early January. The best selection will be available the morning of December 26.
Best Time to Visit for Festivals: Summer is the best time to visit Dublin to enjoy festivals with everything from music festivals like Body & Soul to LGTBQ Pride and the Lobster Festival. The second-best time is mid-March, with the St. Patrick’s Festival the world’s biggest for the holiday, bringing nearly a half-million people to the city center.
Best Time to View Dublin from the Guinness Storehouse: One of the top things to do in Dublin is to take a tour of the Guinness Storehouse. The grand finale is a free Guinness and one of the best views of the city around from the Gravity Bar which sits at the top offering a 360-degree view across Dublin and beyond. Of course, you won’t be able to see much if inclement weather gets in the way, which is why the very best time to head up for the view is in July or September. Arrive as soon as it opens in the morning to capture photos without countless tourists getting in the way.
High Season: (June through August and the week around St. Patrick’s Day, March 17)
The high season primarily coincides with the summer months, which bring the warmest weather of the year to Dublin. It’s unlikely to be too hot. And visitors can expect long days making it easier to squeeze more sights and attractions into their itineraries. As the majority of tourists arrive in during this period, that also means longer lines, thicker crowds, and the highest accommodation and airfare costs of the year. The week around St. Patrick’s Day brings lots of foreign visitors and Irish from throughout the country to Dublin, making it nearly as busy as the summer months, resulting in higher costs at this time as well.
Shoulder Season: (April and May, mid-September through mid-October)
The shoulder season which occurs in late spring and also early autumn, can be an ideal time to visit Dublin. This is when temperatures are usually comfortable, and the sun makes plenty of appearances in between rain showers. The peak prices and peak crowds both begin to decrease, and most activities and attractions will be open.
Low Season: (mid-October through March, except around St. Patrick’s week)
Low season is the least expensive time to visit Dublin, and a great time to avoid the crowds. It’s ideal for those who don’t mind missing out on some of the outdoor adventures and want to enjoy a more authentic experience, with bed-and-breakfast hosts typically having more time to spend with their guests. While some activities won’t be available due to the weather, there are plenty of things to do indoors, from listening to live music in a cozy pub warmed by a roaring fire to exploring fascinating museums.
Dublin Weather by Month
Dublin Weather in January: January is one of the coldest and wettest months of the year in Dublin. While snow isn’t common, it can occur as this is the time when temperatures are most likely to dip below freezing. The average low is 3°C while the high is just four degrees above that at 7°C. The city experiences about 63mm of precipitation over 24 days, and most of the time one can expect there to be grey skies. It’s a good idea to pack a travel umbrella anytime you plan to visit Ireland, but this time of year you’ll also want to warm coat and a lighter rain jacket for layering, along with sweaters, wool socks, waterproof boots, gloves and scarves. Plan for shorter days this month too – on New Year’s Day sunrise is at 8:40 a.m. and sunset at 4:16 p.m. (Average Max Temperature: 7°C. Average Precipitation: 63mm.)
Dublin Weather in February: February won’t be much different than January, with more cold, wet and windy weather, and temperatures remaining about the same on average. It won’t be as wet as the previous month, however, with the average rainfall at just over 46mm. As the length of days are increasing, by late February there are several more hours of daylight for enjoying the sights, and better odds of at least some sunshine. (Average Max Temperature: 7°C. Average Precipitation: 46mm.)
Dublin Weather in March: While March is typically characterized by cool, rainy weather, with an average of 52mm of precipitation, things are warming up and there’s a good chance for sunshine in between the clouds. The average high increases three degrees to 10°C, and the low has creeped up slightly to 4°C. Pack warm winter clothing keeping the rain in mind, along with some lighter items for nicer days. (Average Max Temperature: 10°C. Average Precipitation: 52mm.)
Dublin Weather in April: April can be unpredictable, but visitors should be able to look forward to the sun coming out more often, along with lush green landscapes and colorful flowers. It will still feel a bit chilly, although temperatures are increasing with the average high now at 11°C and the low at 5°C, which means bringing clothing for cool weather along with some items for warmer days, as well as that portable umbrella for the occasional rain shower. There is plenty of daylight now for taking in the sights, with sunrise at about 6 a.m. and sunset about 9 p.m. by the end of the month. (Average Max Temperature: 11°C. Average Precipitation: 50mm.)
Dublin in May: May is typically one of the best months to visit Dublin, with the average high temperature climbing four degrees to 15°C and the days wonderfully long. There are over 16 ½ hours of daylight now, with sunrise at 5:05 a.m. and sunset at 9:41 p.m. on May 31. You’ll still need that umbrella, with slightly more precipitation now than in April with 57mm falling on average over 20 days, but sunshine is almost always right around the corner. Bring a mix of clothing for both warmer and cooler days, like a jacket and sweaters along with short-sleeve shirts. (Average Max Temperature: 15°C. Average Precipitation: 57mm.)
Dublin Weather in June: With summer officially arriving this month, conditions warm quite a bit and some of the longest days of the year are enjoyed. On Summer Solstice, June 21, there will be more than 17 hours of daylight from 4:56 a.m. to 9:56 p.m. The average high temperature has climbed to 17°C and the low is well above freezing at 10°C. While there will be many nice, warm days, rain is common too with 60mm falling over 21 days in June. As this month typically enjoys both cool and sunny days, it also calls for a mix of appropriate clothing. (Average Max Temperature: 17°C. Average Precipitation: 60mm.)
Dublin Weather in July: Some of the warmest weather of the year is enjoyed in July, with the high temperature now averaging 19°C. There are very few days if any that would be considered bathing suit weather in Dublin or anywhere in the country. Layering is still advised now, as is a travel umbrella for inevitable bursts of rain. This is one of the city’s drier months with precipitation dropping back down to 50mm on average, but that just means that you’ll probably be wearing sunglasses more often than a rain jacket. (Average Max Temperature: 19°C. Average Precipitation: 50mm.)
Dublin Weather in August: The rain increases again in August, with 80mm of precipitation over 23 days. The average high temperature remains at 19°C, but that doesn’t mean a rain jacket isn’t necessary as there will still be those occasional summer storms. Pack as you would for July, including a mix of clothing and a travel umbrella, and plan for slight shorter days. By August 31, daylight decreases significantly over what it was at its peak in June, with sunrise at 6:32 a.m. and sunset at 8:17 p.m. (Average Max Temperature: 19°C. Average Precipitation: 80mm.)
Dublin Weather in September: September is another great month to be in Dublin, with temperatures relatively warm during the day and nights cool, usually there’s only a hint of fall in the air. There is often more sunshine now, with precipitation decreasing again down to 56mm on average. It’s all about layers, so pack a few lightweight items along with clothing made with heavier material like wool, along with that travel umbrella. Stylish boots are almost always popular in Dublin but opt for leather rather than suede due to the dampness. (Average Max Temperature: 17°C. Average Precipitation: 56mm.)
Dublin Weather in October: While temperatures are dropping significantly, with the average high down another four degrees to 13°C, autumn can be a great time to visit Dublin. Rainfall increases quite a bit to 76mm on average, but there are usually some wonderful sunny days with fresh, crisp air to go along with the vibrant fall colors. Pack some waterproof gear and look forward to enjoying the sights without having to battle the crowds. By late October, it will be important to plan itineraries for shorter days, with the sun rising at 7:21 a.m. and setting at 4:55 p.m. (Average Max Temperature: 13°C. Average Precipitation: 76mm.)
Dublin Weather in November: By November, chilly weather has usually arrived, with the high temperature now averaging 10°C and the low at 5°C. As winter is fast approaching, packing heavier attire appropriate for the cold is a must, especially during the second half of the month, including scarves, gloves and a warm hat. As with any other month in Dublin, bringing a travel umbrella is a good idea – with about 70mm of rainfall over 24 days, it makes sense to bring some waterproof attire as well.
Dublin Weather in December: Winter is setting now as one of the coldest months in Dublin. The average high dips a couple of degrees to 8°C, while the low remains at 5°C, making snow a relatively rare occurrence. It will be quite cold and damp, with wind making it feel even chillier and precipitation increasing again to 80mm over 23 days in December which means bundling up now is a must. This month sees the year’s shortest day on Winter Solstice, with just 7 ½ hours of daylight, making it important to plan itineraries accordingly.
