What is the temperature today in Ireland?
Met Éireann current readings
- As of May 10, 2026, Met Éireann reports Dublin at 2.3°C with afternoon highs of 10–15°C in moderate north to north-east winds (Met Éireann (national weather service)).
- Tonight brings clear spells and lows of 1–4°C, with possible frost in sheltered spots (Met Éireann).
The national forecast for May 10 shows dry conditions with sunny spells across most of the country. The week ahead (May 11–17) is expected to be drier than usual and slightly cooler than normal, according to Met Éireann’s extended outlook (Met Éireann monthly forecast).
Regional variation is typical: coastal areas in the south and west often run a couple of degrees warmer than inland spots. For example, Sherkin Island in Cork recorded a mean winter temperature of 8.2°C, while Knock in Mayo sat at 5.1°C (Met Éireann).
The implication: Ireland’s spring 2026 is off to a classic start – changeable days, cool nights – but the mild baseline from winter may keep extremes at bay.
What’s the hottest month in Ireland?
Average temperatures by month
- July is Ireland’s warmest month, with mean daily temperatures between 15°C and 20°C (Met Éireann (national weather service)).
- The highest temperature ever recorded in Ireland was 33.3°C at Kilkenny Castle, Co Kilkenny, on June 26, 1887 (Met Éireann).
Summer temperatures in Ireland rarely exceed 25°C except during heatwaves. The climate is maritime, so the Atlantic ocean keeps temperatures moderate – muggy heatwaves are uncommon. August is nearly as warm as July, with averages only about 1°C cooler.
The record of 33.3°C stands above all others; the next highest readings cluster around 30–31°C during rare hot spells.
Ireland’s July averages of 15–20°C seem modest compared to continental Europe, yet the ocean influence makes these temperatures feel cool and often bring damp conditions – a trade-off that defines Irish summers.
The pattern: Ireland’s summers are mild, not scorching – even the record high stays below 35°C – which shapes everything from tourism to agriculture.
Will it snow in Ireland in 2026?
Snowfall patterns in Ireland
- Snowfall in Ireland is rare in lowland areas, typically occurring only 1–2 days per year (Met Éireann (national weather service)).
- Winter 2025/2026 was the 20th mildest since 1900, making significant snow unlikely (Met Éireann climate statement).
Winter forecast from Old Farmer’s Almanac 2025–2026
The Old Farmer’s Almanac predicted a cold winter for Ireland and the UK in 2025–2026 (Old Farmer’s Almanac). However, actual observations from Met Éireann show the season was 1.21°C above the 1961–1990 average, ranking below the top 20 mildest winters on record. The expected cold did not materialise, so the chance of snow remains low for the rest of 2026.
Even in a typical winter, snow that settles on low ground is a rare event. Most snowfall in Ireland falls on higher elevations in the mountains of Wicklow, Mayo and Donegal.
The trade-off: While the Almanac’s cold prediction didn’t verify, the mild trend suggests any snow in 2026 will be confined to high ground and brief events.
Will 2026 be a very cold winter or as hot as 2025?
2025 global temperature record from Berkeley Earth
- 2025 was the warmest year on record globally, with a temperature anomaly of +1.62°C above the 1850–1900 baseline (Berkeley Earth (climate research)).
- This followed a strong El Niño event that ended in mid-2025, which temporarily elevated global averages.
Winter forecast for 2026
For Ireland, winter 2025/2026 was already mild. The seasonal outlook from the Copernicus Climate Change Service (C3S) points to above-average temperatures for May–July 2026 (0.2–1.0°C above normal) (Met Éireann citing C3S). No official long-range forecast for winter 2026/2027 is available yet, but the trend of mild winters across recent years makes a very cold winter less likely.
2025’s global record does not directly predict Ireland’s local weather, but the underlying warming trend means baseline temperatures have shifted upward.
What this means: The global warming trend has not skipped Ireland. Even if 2026 summer is not as hot globally as 2025, local temperatures are likely to stay above the 1991–2020 average.
Is Storm Goretti hitting Ireland?
Storm Goretti path
- Storm Goretti passed over Ireland in March 2025 with little reported impact, according to The Irish Times (The Irish Times).
- No red weather warnings were issued for this storm (The Irish Times).
Reported impact from The Irish Times
The storm tracked across the country bringing some wind and rain, but damage was minimal. Met Éireann’s winter statement for 2025/2026 notes that Storm Chandra on January 27, 2025 brought more significant conditions, with heavy rainfall and storm force winds at Malin Head, Co Donegal (Met Éireann). For Goretti, however, the season’s peak had already passed.
The catch: Even a weak storm season can still bring disruption – but Goretti was a non-event. The typical storm season in Ireland runs from October to March.
Confirmed facts
- Current temperature from Met Éireann for Dublin is 2.3°C (Met Éireann)
- July is the hottest month in Ireland (15–20°C) (Met Éireann)
- 2025 was the warmest year on record per Berkeley Earth (Berkeley Earth)
- Storm Goretti had little impact on Ireland (The Irish Times)
What’s unclear
- Whether significant snow will fall in Ireland in 2026
- If the 2026 summer will be as hot globally as 2025
- Exact long-range forecast for winter 2026/2027 from Met Éireann

For anyone spending time in Ireland in the coming months, the message is one of mild, unsettled weather. The winter just passed was wet and warm, the current spring forecast is typical, and summer signals point to above-average temperatures. The implication for Irish residents and visitors is clear: pack for cool mornings, occasional rain, and sunny spells – and don’t bank on a snowy wonderland. Expect changeability, but not extremes.
