Do you wish to see Ireland to its fullest? Are you wondering when is the best time to visit Ireland also known as the Emerald Isle? I have been to Ireland (both the Northern and the Republic) with my friends. While every month and season offers a different kind of beauty and experience to the traveler, it is still wise to plan your travel period here.

The best time to visit Ireland varies greatly on your motivation to travel. For good weather, come during summer. If you want a quieter experience, consider travelling here during the shoulder months which are April, May, September, or October. For budget-friendly travel, visit Ireland during winter time.

Winter in Ireland

If you are in Ireland anytime during the months of December, January, and February, you are going to experience some of the coldest and darkest days in the country. It can definitely get cold, but it would not come to a point where you’re freezing cold. Frost and snow may occur, most often in the northern and southern parts of Ireland. 

Winter days in Ireland are short, and abundant rainfall should be expected. There are occasional cold spells that happen, with the temperature dropping to as low as -10 °C (14 °F). Make sure to pack clothes that are appropriate for the season.

Spring in Ireland

Spring is when Ireland experiences a gradual change in temperature, and as May comes the whole atmosphere is quite pleasant and definitely milder than the start of spring which is March. Expect cold nights if you are visiting during this season.

During springtime, flowers are in full bloom in Ireland. You will be treated to lush and green landscapes in the countryside, and because rain will be a lot less frequent, you will be able to enjoy more time outdoors.

Summer in Ireland

Cool and mild temperatures start to dominate the atmosphere in Ireland from June to August, and so expect to share the place with huge crowds wanting to visit the tourist spots here. Summer is also the driest season, but do expect rain showers every now and then. Make sure to still pack your rain gear with you on your visit.

During summer, the days are at their longest in Ireland. Sometimes, darkness only sets in at around 10 in the evening. That’s about 17 hours of daylight!

Autumn in Ireland

Prepare to fall even more in love with Ireland during the autumn season. Its natural beauty is on full display during this time, happening from September to November each year. It can be cloudy, windy, and rainy, so make sure to gear up for the season.

Once November kicks in, the temperature gets cooler by the day. You will also see less sunshine, so it is great to plan a little bit more indoor activities during this time.
