What is The Best Time to Visit Ireland: A Seasonal Guide

When you think about visiting Ireland you need to figure out what time of year works best for you. It is not about picking one perfect month. You have to ask yourself what you want. Do you like evenings, lower prices or the lively energy of summer? What is the best time to visit Ireland for you?

March to May: Spring Is a Time to Visit Ireland

Spring is a wonderful time to visit Ireland. Everything is bright and green again. You do not have to deal with a lot of tourists like you do in the summer.

What Is the Weather Like in Spring?

In March the weather in Dublin Ireland is usually around 10 to 12°C during the day. The mornings can feel cool. You will notice the days getting longer really quickly.

This is the time of year when winter is going away. Summer has not arrived yet. By April the temperature during the day is around 12 to 14°C. The weather in April in Dublin Ireland is known for showers that come and go quickly.

It might rain for twenty minutes. Then the sun will come out for the next hour. This keeps happening in May. The weather in May in Ireland is often 15 or 17°C with the sun shining more and the evenings getting longer.

Why Spring Is Perfect for Driving and Exploring

Driving in spring is really nice. The Ring of Kerry is much calmer before the summer crowds arrive and you can find guesthouses in Kerry and Clare that have rooms available and are not too expensive.

You can take ferries to the Aran Islands from April onward. The walking routes in Connemara and Wicklow are in condition after the winter making it a great time for walks along the coast and scenic drives.

Seasonal Highlights in Spring

In mid-March Ireland celebrates St Patricks Festival, which fills Dublin and other towns with parades and cultural events. In May there are garden and food festivals all around the country.

By the end of May the days are really long, 16 hours of daylight which makes it easier to see all the sights. Our tip is to check what time the sun sets before you book your trip because those long days give you a lot of time to explore.

Ireland is really beautiful in the summer. The warm weather and long evenings make your days feel completely different.

Why Early Summer Is Perfect for Exploring Ireland

June is a time to visit Ireland because you get the summer feeling without all the crowds. The roads are generally quiet before the school holidays start making it easier to drive on the Wild Atlantic Way and up, into Northern Ireland.

July and August: Peak Season, Festivals and Buzz Across the Emerald Isle

July and August are the peak season in Ireland. This really affects things. Hotels in towns by the sea can be booked months ahead. It can cost twice as much to rent a car compared to the spring.

When Does Travelling in Summer Make Sense?

When Is the Rainy Season in Ireland?

Ireland does not really have a season that you can put your finger on. It rains all year round because weather systems from the Atlantic Ocean keep moving across the country.
