Ireland Heatwave 2026: Live Warnings, Temperatures & What It Means for Travel

Last updated: Jul 29, 2026

Ireland had two separate heatwaves in 2026, one in late June and another in mid-July, both confirmed by Met Éireann. As of 29 July 2026, neither is active.

A “heatwave” in Ireland looks very different from one in Spain or the Gulf, and that is exactly why it makes headlines. When the rest of Europe sits under a 40°C heat dome, Ireland catches the edge of it: warm, humid, and hot enough to break local records, while staying comfortable by Mediterranean standards.

Here is what counts as a heatwave in Ireland, how hot it got twice this year, why a hosepipe ban is still running, and what it all means if you are planning a trip.

Is Ireland having a heatwave right now?

No. Met Éireann confirmed on 28 July 2026 that it is ruling out a return to heatwave conditions this week, with weather described as mixed and changeable and highs mostly running from the high teens to low 20s°C.

The most recent heatwave ended on 20 July 2026, when Moorepark, Co Cork cooled to 24.9°C, just under the 25°C mark needed to keep the spell going.

No heatwave in place as of 29 July 2026.
No weather warning currently in force.
A nationwide hosepipe ban remains active due to drought.

Ireland’s two heatwaves in 2026

Ireland met its official heatwave threshold twice this year: once in late June and again in mid-July.

Heatwave	Dates	Peak temperature	Stations that qualified
Late June	22–26 June 2026	32.2°C at Athenry, Co Galway (25 June)	Widespread; nine stations set all-time overnight-high records
Mid-July	Peaked around 15–20 July 2026	29.3°C (provisional) at Shannon Airport, Co Clare	Shannon, Moorepark, Athenry, Valentia, Oak Park

June 2026 was Ireland’s 4th warmest June since national records began in 1900, according to Met Éireann’s official June climate statement. Phoenix Park in Dublin recorded 28.2°C that month, its warmest June in 127 years of records.

How hot did it get, and how does that compare with the record?

The peak reading of the year so far is 32.2°C at Athenry, Co Galway on 25 June, close to but below Ireland’s all-time record. Both 2026 heatwaves also fell well short of Ireland’s longest recorded heatwave.

All-time Irish record: 33.3°C at Kilkenny Castle, set in 1887.
2026 peak so far: 32.2°C at Athenry, Co Galway, 25 June.
Mid-July peak: 29.3°C (provisional) at Shannon Airport, among the warmest July readings on record.
Longest heatwave on record: 14 consecutive days, 14–27 August 1976, at Ballybrittas, Co Laois and Birr, Co Offaly.

What counts as a heatwave in Ireland?

Ireland’s threshold is deliberately much lower than in hotter countries. Met Éireann declares a heatwave when a station records five or more consecutive days at 25°C or above.

A higher bar would rarely be met in a maritime climate like Ireland’s, so Met Éireann sets the threshold low enough that heatwaves remain a meaningful, if uncommon, event. By that definition, a run of 26°C days is a genuine heatwave in Ireland, even though it would barely register in Riyadh or Seville.

The hosepipe ban: what it means for travellers

A nationwide hosepipe ban is currently in force, but it does not affect drinking water, hotel operations, or day-to-day travel. Uisce Éireann’s Water Conservation Order began covering Dublin and nearby counties from 16 July 2026, then extended nationwide from 22–24 July.

It is scheduled to run until 26 August 2026, though it could end earlier or be extended depending on conditions.

Restricts hosepipe use for gardens, car washing, and paddling pools.
Does not affect drinking water supply.
Does not affect hotel operations.
Hand-held containers, such as watering cans, are still allowed.

Ireland vs the rest of Europe

Perspective helps: the same June heat dome that gave Ireland its 32.2°C peak pushed temperatures past 40°C across Spain, Portugal, Italy, and southern France, and gave the UK one of its hottest June days on record.

For travellers trying to escape extreme heat, Ireland sits firmly in the comfortable zone, which is why it works well as a cooler-summer alternative.

Is it safe to travel to Ireland during a heatwave?

For most visitors, yes. Irish heatwaves are mild by global standards, and the country is green, breezy, and rarely uncomfortable for long.

The main things to watch are strong sun, warm nights that disrupt sleep, and occasional thundery breakdowns that can bring sudden downpours. A few simple habits cover it.

Carry water and stay hydrated, especially when walking or hiking.
Use sunscreen and a hat. Irish sun burns faster than the cool air implies.
Plan indoor or coastal options for the hottest hours.
Check Met Éireann warnings each morning for heat and thunderstorms.
Choose accommodation with fans or air conditioning if warm nights bother you, as most Irish homes and hotels are built for cool weather.

Northern Ireland and Dublin

Dublin sits on the cooler east coast. During the June heatwave, the Phoenix Park station still reached 28.2°C, its warmest June on record, even though it typically runs a few degrees below the warmest western and southern spots.

Northern Ireland shares the same weather systems but is covered separately by the UK Met Office rather than Met Éireann. It typically sees similar conditions, with peaks usually a touch lower than the warmest spots in the Republic.

Whether you are in Belfast or Galway, the same heat habits apply.

Frequently Asked Questions

Is Ireland having a heatwave right now?

No. Met Éireann ruled out a return to heatwave conditions as of 28 July 2026, with the most recent spell ending on 20 July.

How many heatwaves has Ireland had in 2026?

Two. One in late June (peaking at 32.2°C at Athenry) and one in mid-July (peaking at a provisional 29.3°C at Shannon Airport).

What temperature counts as a heatwave in Ireland?

Five or more consecutive days at 25°C or above at the same Met Éireann station. The threshold is lower than in hotter countries, so a run of high-twenties days qualifies.

What is the hottest temperature ever recorded in Ireland?

33.3°C, recorded at Kilkenny Castle in 1887. The closest 2026 got was 32.2°C at Athenry, Co Galway, on 25 June.

Is there a hosepipe ban in Ireland?

Yes. A nationwide Water Conservation Order is in force until 26 August 2026, restricting garden and car hosepipe use, though it does not affect drinking water or hotel operations.

Is it safe to travel to Ireland during a heatwave?

For most travellers, yes. Irish heatwaves are mild by global standards; carry water, use sunscreen, and check daily warnings for heat and thunderstorms.
