1. Defining "The Best Time" is Debatable

Do take every guide identifying the ideal months to go to Ireland with a grain of salt! The optimal time to visit depends on your preferences, so you must weigh the advantages and drawbacks of each month.

2. What You Need to Consider

Each season has its advantages and disadvantages. During the summer months, the days are long, allowing for extensive exploration. The "Shoulder Season" has fewer crowds, but winter has yet to establish its grip. We'll delve deeper into this subject below.

3. You're Often Taking a Calculated Risk

Determining when to visit Ireland might feel like you're playing roulette, as the weather in Ireland is unpredictable at best. In a perfect world, you'd experience sunny, warm days all through the Irish summer, but as you'll discover, that's frequently not the case.

4. The Seasons in Ireland

Ireland's seasons are easy to classify; Summer in Ireland: June, July, and August, Autumn in Ireland: September, October, and November, Winter in Ireland: December, January, and February, and Spring in Ireland: March, April, and May. Here are the tourist seasons:

Peak Season: June to September Shoulder Season: April to May Off-Peak: November to February

5. My Personal Opinion

Since releasing the most significant collection of Irish road trip itineraries globally, we are often asked about the best season to visit Ireland. Having resided here for 33 years, I'd suggest that May, September, and October are challenging to match. During May, the days are long and typically mild, while during September and October, you are past the peak summer season, the winter chill has yet to set in, and many areas are far less crowded.

Overall, the best time to visit Ireland is dependent on your preferences. No matter when you choose to visit, Ireland has something to offer for everyone.

March has been hailed by many as the opportune time to explore Ireland, largely due to the St. Patrick's Day festivities that set the entire country abuzz. However, there are other compelling reasons to plan a visit to Ireland in March as well. Firstly, this is the last month before the surge in demand that typically accompanies the Easter holidays, which means cheaper accommodation rates. Additionally, March marks the onset of spring, which usually means better weather, with longer days, beginning at 07:12 and ending at 18:17.

Despite these benefits, it is important to note that March weather can be unpredictable and extreme, with possibilities ranging from snowstorms to heavy rainfall or even scorching heat, as evidenced by the past five years of weather patterns. Another potential downside is the inflated cost of flights during this period.

Moving on to April, it is widely considered as the most excellent time to visit Ireland, alongside May and October. One key advantage of this month is that the weather is usually milder, with long daylight hours that begin at 06:23 and end at 20:00. This period also guarantees lower trip expenses, specifically lower flight costs. Nonetheless, it is critical to keep in mind that there are potential downsides to traveling to Ireland in April. One such disadvantage is the fact that schools have two weeks off around Easter, resulting in a limited availability of accommodation in some regions. Additionally, the weather can be very unpredictable, and it is always prudent to consult the April Weather Guide provided on our site.

May is an ideal time to visit Ireland as the weather is mild, with warmer temperatures ranging from 9.0 °C to 13.0 °C on average over the last three years. As such, May provides the best of both worlds - warm and sunny days while avoiding the summer influx of tourists. The days are longer, starting at 05:17 and ending at 21:26, and this prolonged daylight hour usually brings with it a lively atmosphere, heightening the Summer buzz. Another advantage of visiting Ireland in May is that it coincides with the beginning of the festival season, as outlined in our Irish Festivals Calendar. The flip side of the coin is that May weather can be terrible, and accommodation prices and crowds tend to surge.

Finally, June hits the sweet spot between the arrival of summer and the warmth of May. As a result, it is considered the best time to visit Ireland along with May. The weather is typically mild, and daylight hours are long, beginning at 04:57 and ending at 22:03. The downside of June is that it marks the beginning of peak tourist season, which comes with increased prices and crowds. Nevertheless, our June Weather Guide available on our site can help you navigate these potential challenges.

Experience the beauty of summer in Ireland by traveling in June. This promising month offers dry and warm weather, with an average of 18°C high and 11.6°C low temperatures. Many tourists consider June the ideal time to travel to Ireland. The weather is fantastic, and the daylight extends from 05:03 to 21:42, giving you more time to explore. Additionally, music festivals are held throughout the country that adds an extra fun factor. However, the downside of visiting in June is that prices soar high, and the crowds can be overwhelming.

If you prioritize favorable weather conditions, then July is your best pick. Although it's not guaranteed, you are more likely to encounter good weather conditions in July than any other month. You can expect an average high temperature of 19°C and lo of 12°C. The sun rises at 05:01 and sets at 21:56, and the vibrant atmosphere brings life to Ireland’s towns, villages, and cities. However, traveling in July has its disadvantages, such as increased prices for hotels, B&Bs, and Airbnbs, and the overwhelming crowds due to school holidays.

August is another highly recommended month to visit Ireland, showcasing the country’s best season. The long days and warm weather provide plenty of opportunities to explore and discover new places across the vast range of counties. However, similar to July, the peak demand for accommodation can result in inflated prices, and the crowds can cause an inconvenience during travel. Overall, August's pros significantly outweigh its cons, and it is one of the best months to visit Ireland.

When considering the best time to visit Ireland, it's hard to ignore the benefits of the weather, long days, and summer buzz that can be found there. With highs of 18°C and lows of 11°C, the weather is usually mild and pleasant. Visitors can expect 16 hours of daylight during the summer months, providing ample time to explore all that Ireland has to offer.

However, there are also some disadvantages to consider. September, for example, can be a great time to visit as the weather is mild and the crowds have thinned out, but it can also be unpredictable. Similarly, October offers the chance to see Ireland's stunning autumn foliage while avoiding the peak-season crowds, but the days are shorter and the weather can be unpredictable.

As for November, while the weather may be less than ideal, visitors can still find some advantages to traveling during this time. The crowds are even smaller than in September and October, and prices for accommodations in less popular locations may be lower. However, with the sun rising later in the day and setting earlier, visitors should be prepared to make the most of their limited daylight hours.

In summary, whether you're looking for great weather, long days, or fewer crowds, there are advantages and disadvantages to visiting Ireland at any time of year. Consider the factors that matter most to you and plan accordingly.

Looking for a city break in Ireland? November is one of the prime months to go, with many Christmas markets in full swing from mid-month. You can enjoy the cool and crisp weather, with the average temperature hovering between 12°C and 9.5°C.

Advantages of a November visit include avoiding crowds at most attractions (except for places with Christmas markets), enjoying more affordable accommodation in off-the-beaten-track towns and villages, and cheaper flights during the off-season. However, be aware that the days are shorter and some seasonal attractions in Ireland may be closed due to the season. Also, be prepared for potentially wintery weather, as November can bring mild, stormy, or freezing conditions.

For a cosy and festive vibe, December is the perfect time to visit Ireland, with Christmas markets, Christmas lights, big open fires, and cheaper accommodation. Average temperatures are similar to November, around 5°C, but can vary.

Advantages of a December visit include experiencing the festive buzz, encountering fewer crowds at attractions, and enjoying cheaper accommodation in off-the-beaten-track towns and villages. However, flights in December can be extremely pricey due to the holiday season. Be prepared for short days and potentially rainy and windy weather, although December has been mild in recent years.

Frequently asked questions about the best time to visit Ireland abound, from what to wear to when's the warmest time to go. Generally, my recommendation is to visit during the shoulder season, specifically September, October, and May, for pleasant weather without peak crowds. However, if you've never been before, the summer months offer plenty of daylight hours for exploring. As for when to go, it depends on your budget, with off-peak times being cheaper and shoulder season offering a balance of affordability and pleasant weather.
