Yes, it can get hot in Ireland, particularly during July and August, when temperatures sometimes exceed 30°C (86°F), with recent summers like 2025 being among the warmest on record. While typical summer highs are usually in the high teens to low 20s°C (64-68°F), heatwaves are becoming more common.
July is the warmest month in Ireland. Average daytime temperatures hit a balmy 16°C (60°F). During settled summer weather, Ireland enjoys frequent highs in the mid 20s centigrade (80°F and above). Even better, sea temperatures top out at around 15°C (59°F) in July and August.
Extreme heat and cold are both rare throughout the country. Summer temperatures exceeding 30 °C are rare, usually only occurring every few years (2025, 2022, 2021, 2018, 2016, 2013, 2006, 2003, 1995, 1990, 1989, 1983, 1976 and 1975 are recent examples), although they commonly reach the high 20s most summers.
No, Ireland isn't generally colder than the UK; both have mild, temperate climates due to the Atlantic, but the UK experiences more temperature variation, with Scotland being colder and Southeast England warmer, while Ireland tends to have slightly milder winters and cooler summers overall, but receives significantly more rainfall, especially in the west. Ireland's west coast gets more Atlantic influence, making it milder and wetter, while Britain's interior and east can feel colder in winter (less rain/snow) and warmer in summer (more sun), but Scotland is the coldest UK region.
“Now, as we produce the first Irish-based seasonal high temperature attribution analysis we know for certain that Ireland is seeing a direct effect of global climate change.” Bergin said that the high temperatures seen this summer will become more regular with the highest temperatures set to get even higher.

How hot will Ireland be in 2050?
Projections of future change (measured relative to the 1960-1991 baseline) for Northern Ireland if high emissions continue are an increase in mean winter temperature very likely to be between 0.3-1.7ºC by 2020s, 1-2.9ºC by 2050s and 1.7-4.4ºC by 2080s, and an increase in mean summer temperature very likely to be ...
Cities like Galway and Manchester are comparably affordable, though still more expensive than many more rural areas of both countries. In general, for those looking for a city lifestyle in a more affordable environment, Ireland may be the better choice, with both Dublin and Galway cheaper on average than London.
When it comes to natural beauty, the Scotland vs. Ireland debate can go either way. After all, both are incredibly picturesque. But we decided to give this one to Scotland for the dramatic variety you'll find when on one of our Scotland tours.
As a tourist in Ireland, avoid mocking the accent, using phrases like "top o' the mornin'," claiming 100% Irish heritage, or ordering "Irish Car Bombs" in pubs; also, don't assume everyone drinks, disrespect sensitive topics (politics/religion/The Troubles), confuse Ireland with the UK, or only visit Dublin, remembering to dress for variable weather, respect local customs (like buying rounds), and explore beyond main sights.
The sunniest months in Ireland are May and June. Still, all summer long you have a good chance of seeing the sun, and daylight stretches long into the evening, especially in late June and July. Between November and February, the country is dark, cold, and wet. December and January are the rainiest months in Ireland.
The last time a heatwave was observed in Ireland began Monday 4 to Saturday 9 September 2023 (6 days) at four synoptics stations (Gurteen, Co Tipperary, Oak Park, Co Carlow, Shannon Airport, Co Clare and Mount Dillon, Co Roscommon) and three climate stations (Greenshill, Co Kilkenny, Athy, Co.
The best weather in Ireland by month tends to be June, July and August, while the worst tends to be January and February, but poor weather conditions can hit at any time, as they have in the past.
Bathing water quality is monitored during the summer bathing season which is between 1 June and 15 September. Some local authorities also voluntarily monitor outside of the summer bathing season.
Met Éireann records reveal that since 1961 there have been just nine Christmas days when snow was recorded as lying on the ground at 9am – the strict standard adopted for measuring such events. Broadening out the criteria, there were 16 Christmas days when snow fell somewhere at some stage during the day.
Air masses of polar origin are most common but they usually have a long track over the Atlantic before reaching Ireland. Even southerly or south-westerly winds can bring us returning polar air, albeit highly modified by its excursion into the warm waters of the mid Atlantic.
The biggest problem in Ireland is widely considered to be the severe housing crisis, marked by a lack of affordable homes, soaring rents, and record levels of homelessness, exacerbated by rapid population growth and insufficient infrastructure. This is closely followed by related issues like the high cost of living, infrastructure shortfalls (transport, healthcare, water), and challenges from increased migration, all straining services and making it harder for many, especially young people, to find stable housing.
Thanks to the Common Travel Area (CTA), UK citizens can enter Ireland, live there and access healthcare and social benefits. They can also move to Ireland to study or work, receiving the same terms as locals with no differences in rights or entitlements.
See the Background Notes for further information. Figure 3.1 shows the proportion of the population in each ethnic group in Ireland and Northern Ireland. In Ireland in 2022, 86% of the population identified as White, compared with 97% in Northern Ireland in 2021.
Earth will remain habitable for complex life, including humans, for roughly another 1 to 1.5 billion years, primarily because the Sun's increasing luminosity will eventually cause runaway oceans and extreme heat, making the planet uninhabitable long before the Sun becomes a red giant in about 5 billion years. The process begins sooner, with signs of severe climate change and ecosystem collapse potentially appearing within a few hundred million years, but the planet becomes truly inhospitable for humans around 1.3 billion years from now.
What countries will be too hot to live in by 2050?
By 2050 around 970 cities will be at least this hot, with much higher exposure in Asia, Africa and North America (see Figure 1). Average high temperatures of 35°C (95°F) will mean that heatwaves will become far more intense.
