Ireland is a wonderful place to visit year round. However, some months of the year are better than others. Knowing when to go to Ireland and the trade-offs (like smaller crowds or longer daylight hours) can help you pick the perfect time.
November, December, January & February
The winter months have limited daylight hours, which means less time at the attractions and more time in the pub, which is not entirely a bad trade. :-)
March is the month of St. Patrick’s Day. Many people love to travel to Ireland during this blessed (and fun!) holiday. Towns will be full of life with colorful parades and other events, but lines may be long, restaurants may be full, and daylight will still be shorter than spring and summer.
April, May, early June, September & early October
You can find great deals on flights, cars and accommodations during the shoulder season. Attractions are open and there will not be as much traffic on the roads or at the sites. Daylight hours will be long in the spring and not to short in early fall, so you can enjoy museums, historical and other sites without hurry. If you want my best recommendation on when to go to Ireland–it’s these months.
July & August
July and August are the peak travel months. The crowds will be heavier and the best accommodations will fill up fast, but with careful planning, you can avoid the masses, travel off the beaten path a little and have an exceptional time.
Irish weather is unpredictable all year-long. On any given day, be it December or July, you might experience four seasons of weather. This is all a part of Ireland’s charm. Be prepared for it by dressing in layers. Don’t try to predict the weather or the best days/months to travel. Just be open-minded and ready for anything. You will have a great time!
When to go to Ireland
If you have any time of the year to plan your trip, go during the shoulder months, particularly in late May or early June, and September or early October. The days are long, the weather is mild and there aren’t many other tourists around. You may just find you get a few places all to yourself!
