Springtime in Ireland brings a welcome change, with longer days and warmer temperatures. The rain is still persistent, but the increasing sunlight makes it feel much more pleasant to be outside.

This is an excellent time of year to visit Ireland for a hiking tour, as long as you pay attention to the ever-changing weather conditions.

The Irish Summer – June, July and August

Summer and early autumn are considered the best months for hiking in Ireland. We generally have warm summers. The days are longer, temperatures are milder, and there’s generally less rainfall than during other times of the year.

What’s more, Ireland’s natural beauty is incredibly vibrant during these months, so if you’re looking for an unforgettable experience, this is the perfect time to go!

The Autumn in Ireland is something special – September, October November.

Autumn in Ireland is something truly unique and magical. The lush green landscapes, the rolling hills, and the fresh, crisp air create a perfect backdrop for an unforgettable hiking or walking tour. Imagine yourself strolling through Ireland’s stunning countryside as the leaves turn to vibrant shades of gold, red and orange.

Ireland’s weather patterns have changed over the centuries, but it is generally temperate, with mild winters and cool summers. From May to October, there are usually plenty of bright sunny days ideal for exploring Ireland’s great outdoors.

Winter in Ireland – December, January, and February

The winter months in the Emerald Isle are usually relatively mild, with temperatures rarely dropping below freezing. Still, due to the abundance of rain and wind that Ireland receives during this time of year, it’s best to avoid hiking trips in extreme weather conditions.

When planning your hiking tour, you should also consider shorter days and more extended periods of darkness.

As Ireland enters its winter season again, things start to get chilly. Temperatures tend to hover just above freezing point, and rainfall increases significantly. While it may not be ideal weather for a hike, if you come prepared with all the necessary gear, you can still have a great time.

The Influence of the Atlantic Ocean and the Gulf Stream on Ireland’s Weather


The Irish weather is influenced mainly by the North Atlantic Drift and Ireland’s proximity to mainland Europe and the UK. The North Atlantic Drift, also known as the Gulf Stream, brings warm air from the Caribbean across Ireland, helping to make Ireland a milder climate than its latitude would typically suggest.

Meanwhile, low-pressure systems from mainland Europe and the UK also affect Ireland’s weather. This combination of influences results in Ireland experiencing much wetter winters and milder summers than other parts of Northern Europe with similar latitudes.

The east coast, especially the southeast coast of Ireland, has significantly less rain than the west coast.

What is Met Eireann, and what do they do?

Ireland’s Met Eireann is the national meteorological service. It provides regular forecasts and warnings about Ireland’s weather, helping residents and visitors stay informed about Ireland’s ever-changing climate.

All their information is available on their website and social media accounts, making it easy to keep up with the latest updates. They also have a great app available for download in the app store on your phone.

Their detailed data and forecasting make them an invaluable resource for anyone planning a visit to Ireland – whether it’s a hiking tour in May or a winter holiday in December!

Climate history and education

Met Eireann also regularly publishes educational materials on Ireland’s climate history, which can help you learn more about Ireland’s unique weather patterns.

By understanding how Ireland has changed over the years, we can better prepare ourselves for Ireland’s future climate and make sure to plan for any potential changes.

This knowledge can also help ensure that Ireland stays as beautiful and vibrant as it has always been – something everyone can appreciate!
