Dublin Weather

Ireland's climate is governed by the moist air from the Atlantic Ocean and the effects of the Gulf Stream. This means the temperatures are fairly mild, despite its northern latitude. The weather can be very changeable year-round, so expect a mixture of sunny conditions and rain. The winter period can see lengthy spells of rain or cloudy weather and no sunshine at all.

Summer

If you are looking to visit Dublin during the warmest months, then July and August have average temperatures of 15°C to 20°C. Rarely does the mercury climb much above this, except for odd days. The long summer days can be appealing, as it doesn't get completely dark until around 23:00. You may get an average of 6 hours of sunshine, but don't be fooled into thinking that the weather will remain settled.

Summers can be notoriously wet, with rainfall fairly consistent all year. Good weather in the mornings can soon deteriorate, leaving cloudy skies and rain by the afternoon. On the other hand, if the morning starts dull and wet, don't lose hope, as it may clear throughout the day.

Other seasons

The spring and autumn periods are considered by many to be the best times to visit Dublin, as the temperatures are pleasantly mild and the attractions free from crowds. Prices also tend to be a little cheaper than the peak summer months; however, check your dates carefully, as there are many festivals, cultural events and sporting fixtures, when prices increase and availability can be scarce.

If you are here for more than a few days then you will almost certainly experience some rain. Ireland has a lush and green countryside for a good reason. Be prepared for sunshine, showers and fine misty rain than can last for hours.

Dublin doesn't suffer from extreme weather between seasons, but winter can be an inhospitable time to visit. January and February are the coldest months, with daily temperatures averaging from 4°C to 8°C. Major snowfalls are rare, but it can rain every day for weeks. The city is becoming a popular destination throughout the year, but it's worth remembering that some restaurants and guesthouses close down around October and don't reopen until Easter.
