- 520 views
Make a beeline for Ireland in September to cover its major sights while avoiding crowds. Like most parts of Europe, the school year starts in September in Ireland, which means that the number of locals and tourists jostling for the best photos of the Giant’s Causeway and lining up for Dublin’s famous attractions drops.
It is something of a local cliché in the country that September is better than summer, and most travelers visiting Ireland in September will come across talks about an ‘Indian summer’ after a day or two when the mercury breaches the 20°C mark.
WEATHER IN IRELAND IN SEPTEMBER
For anyone heading to Ireland in September, the keyword to remember is ‘changeable’. The country is subject to sudden changes in temperature conditions during this time of year, with average temperatures across the country ranging from 10°C to 17°C.
There can also be rain around. The national average is between ten and 20 days of rain during September depending on where you are, although it is worth noting that northern and southern parts of the country receive more rainfall (around 95mm) than Dublin (60mm) during this time of year. Plus, much of the rain is intermittent. While a shower can obviously interrupt your fun, it also makes Ireland a great place to hunt for rainbows during this month.
Another huge bonus of traveling in September is long days. The sun rises at around 6.30 am and sets after 8:00 pm, giving you plenty of time to explore the country.

WHY VISIT IRELAND IN SEPTEMBER
Moving your annual holidays from August to September can really pay off when it comes to discovering Ireland. Below are a few reasons why you might want to fly into this country during this time of year.
- Better rates: The fall in prices at the start of September can be surprising. This results in hotels competing among themselves for customers and offering discounts. You can also find some amazing deals on flights during this month.
- Fewer crowds: Less crowds mean that you need not fight for your place among hordes of fellow tourists. Take in the highlights of the country at your own pace.
- Festivals: Head to Dublin which celebrates the Fringe Festival, a two-week jamboree featuring up-and-coming performing artists, during this time of year. Belfast, on the other hand, sees International Tattoo, a display of parades and musical events with a military bent. Head for Galway at the end of the month if you are a foodie and be part of the International Oyster and Seafood Festival.
WHERE TO GO AND WHAT TO DO
This is one of the best times of year to explore Ireland’s southwestern coast. Some of the destinations in this region that you should not miss out on a trip to Kerry and Mayo. For the truly bold, a dip in the sea is actually more doable during this month, as the heat of the summer months means the water is at its warmest in September.
Hiking is another possibility. There are numerous trails to follow on the Dingle Peninsula (the Dingle Way) as well as the Iveragh Peninsula (the Kerry Way). Hiring a bike can open up more options, including the Wild Atlantic Way, with bike trails leading you past gnarly seascapes and picturesque local villages.
Dublin also offers lots of beautiful walks. The mountains to the south of the city have a number of trails suitable for travelers of all fitness levels. Here you can go in tours to historic sights, such as the Fairy Castle or the Hellfire Club, or reconnect with nature in local woods.
The city’s main attractions come into their own when the weather takes a turn for the worst. You can have a pint at the Temple Bar, visit the Guinness Storehouse Factory, discover Dublin Castle and decide if you prefer Christ Church Cathedral or Saint Patrick’s Cathedral – all without getting cold or wet!
Similarly, the north of the country also offers both indoor and outdoor activities. Head to Belfast is a city steeped in history. For those interested in politics, it is home to Stormont, Northern Ireland’s parliament. For history buffs, Belfast Castle offers a journey back to the past coupled with amazing views of the city and the option of an afternoon tea, while Titanic Belfast is an attraction that tells the story of the world’s most tragic shipwreck.
Venturing out, you might want to go on a hiking trip through the Causeway Coast, which culminates in the Giant's Causeway. Another option for a hike is the Ulster Way. At 636 miles long, this trail offers hikers the chance to explore any number of peaks, forests and lakes, not to mention Ulster’s craggy coast. Look out for ‘Game of Thrones’ fans, because several scenes from the series were shot here.
What to bring
While some summer clothes may be in order, be sensible rather than optimistic. Pack long-sleeved garments along with jeans and trousers as well as at least one warm sweater. If you intend to go hiking, make sure you bring suitable footwear in case conditions get muddy or treacherous. And if you do not fancy hauling your winter coat with you, make do with a raincoat and a sturdy umbrella.
