When is the Best Time to Visit Dublin?

The best time to visit Dublin is June through August, when the skies are sunniest and average high temperatures are in the upper teens. (Though rain is always a possibility in Dublin.) Prices will be higher and lines will be longer in the summer. For good weather, manageable crowds, and lower prices, visit in April, May, or mid-September through mid-October.

  • Best Time to Visit Dublin for Good 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 – temperatures are 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, with nearly 17 hours of daylight on July 1, making it easy to take in more outdoor attractions.
  • 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 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; there’s something for everyone, with festivals like Body & Soul, LGTBQ Pride, and the Lobster Festival. The second-best time is mid-March for the St. Patrick’s Festival, the world’s biggest, which brings 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 from the top-floor Gravity Bar, which offers a 360-degree view across Dublin and beyond. Of course, you won’t be able to see much in the rain, 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 your shot.

Dublin Travel Seasons

  • High Season (June through August, St. Patrick’s Day): The high season primarily coincides with the summer months, which bring the warmest weather of the year to Dublin, though it’s unlikely to be too hot – and long summer days make it easier to squeeze in more sights and attractions. With the majority of tourists arriving in summer, prepare for longer lines, thicker crowds, and the highest accommodation and airfare costs of the year. The week around St. Patrick’s Day attracts lots of Irish and foreign visitors 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 seasons of late spring and early autumn can be an ideal time to visit Dublin. Temperatures are usually comfortable, and the sun makes plenty of appearances in between rain showers. Prices and crowds are not at their highest, and most activities and attractions will be open.
  • Low Season (Mid-October through March, except around St. Patrick’s Day): Low season is the least expensive time to visit Dublin, and a great time to avoid crowds. It’s ideal for those who don’t mind missing out on some outdoor activities and want to enjoy a more authentic experience, as bed-and-breakfast hosts typically have 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, like exploring museums and listening to live music in cozy, fire-warmed pubs.

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 is possible, with temperatures likely to dip below freezing at times. The average low is 3°C, while the high is just 7°C. The city experiences about 63mm of precipitation over 24 days, grey skies can be expected most of the time. 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 is much like January, with more cold, wet, and windy weather, and temperatures remaining about the same on average. It won’t be quite as wet as the previous month, however, with average rainfall at just over 46mm. As day length increases, by late February there are several more hours of daylight for enjoying outdoor sights, and better odds of seeing some sunshine. (Average Max Temperature: 7°C. Average Precipitation: 46mm.)
  • Dublin Weather in March: March is typically characterized by cool, rainy weather (with an average of 52mm of precipitation), things are definitely 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 can look forward to the sun peeking out more often, over lush green landscapes and colorful flowers. It will still feel a bit chilly, although temperatures are increasing; the average high is now at 11°C and the low at 5°C. Pack 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 around 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 wonderfully long days and an average high temperature of 15°C. 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 (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 the official arrival of summer, conditions warm quite a bit and days are the longest of the year. 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 also common, 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 Dublin’s warmest weather is enjoyed in July, with high temperatures averaging 19°C – though there are very few days, if any, that would be considered “bathing suit weather” in Dublin (or anywhere in Ireland). Layering is still advised now, as is a travel umbrella for inevitable bursts of rain. This is one of the city’s drier months as well, with precipitation dropping back down to 50mm on average; you’ll likely 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, averaging 80mm of precipitation over 23 days. The average high temperature remains at 19°C, but a rain jacket is still necessary, as occasional summer storms can be expected. Pack as you would for July, including a mix of clothing and a travel umbrella, and plan for slightly shorter days. By August 31, daylight decreases significantly from its June peak, 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 relatively warm temperatures during the day and cool nights, usually with just 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 a 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 Dublin temperatures drop significantly in October (the average high is 13°C) and rainfall increases to 76mm on average, autumn can be a great time to visit Dublin. There are usually some wonderful sunny days with fresh, crisp air and 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, seriously chilly weather has arrived, with the high temperature now averaging 10°C and the low at 5°C. Winter is fast approaching, so packing heavier, cold-appropriate attire 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, a travel umbrella is a good idea – and with about 70mm of rainfall over 24 days, it makes sense to bring some waterproof attire as well. (Average Max Temperature: 10ºC. Average Precipitation: 70mm.)
  • Dublin Weather in December: Winter begins during 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, so snow is a relatively rare occurrence. It will be quite cold and damp (with wind making it feel even chillier) and precipitation increases to 80mm over 23 days in December; bundling up is a must. This month sees the year’s shortest day on Winter Solstice, with just 7 ½ hours of daylight, so plan itineraries accordingly. (Average Max Temperature: 8ºC. Average Precipitation: 80mm.)
