Sizzling July is 12th hottest month in Irish recorded history
30 degrees
in some areas, according to Met Éireann.
Continuing the recent 'warmer-than-normal monthly trend', Met Éireann said last month was the fifth in a row with temperatures in the top nine monthly averages recorded over the last 126 years.
Also the ninth warmest July on record, last month had an average temperature of 16.59 degrees, 1.21 degrees warmer than the 1991 to 2020 long-term average (LTA).
The warmest month of 2025, it was the hottest July since 2021, when the mean temperature reached 16.83 degrees.

It was 1.74 degrees above the LTA recorded from 1961 to 1990, and was bolstered by a particularly hot period midway through.
A build-up of the Azores High over Ireland resulted in temperatures rising above 27 degrees each day from July 10th to July 13th.
The Azores High, which originates in the Azores off the coast of west Africa, is a large atmospheric high-pressure centre that develops over the subtropical region of the eastern North Atlantic ocean.

The highest temperature of the month, and of the year so far, was 31.1 degrees recorded at Mount Dillon, Co Roscommon, on July 12th.
It was Mount Dillon's second-highest maximum temperature on record, and the highest recorded in Ireland since August 2022 when Oak Park, Co Carlow reported 31.7 degrees.
Two other weather stations surpassed 30 degrees on July 12th, with a high of 30.6 degrees recorded at Shannon Airport, Co Clare, and 30.2 degrees recorded at Oak Park, Co Carlow.
The Malin Head station in Co Donegal, meanwhile, recorded its highest July maximum temperature (27.6 degrees) since its records began 70 years ago.

Although among the warmest, it was also
the wettest July
since 2023 and 33rd wettest since 1941.
A monthly average of 96mm of rainfall was recorded, slightly above average at 103 per cent
of the 1991-2020 LTA.
However, rainfall was unevenly distributed across the country, with parts of the east and west seeing 'well above average rainfall', Met Éireann said.
Areas in the south and north midlands, meanwhile, saw significantly below average rainfall.
Rainfall values as a percentage of the most recent long-term average from 1991-2020 ranged from 49 per cent at Ballyhaise, Co Cavan, to 161 per cent at Casement Aerodrome, Co Dublin.
On July 21st, the Casement Aerodrome station recorded its wettest July day (50.9mm) since its records began 61 years ago.
The highest daily rainfall total was 55.4mm at Dunsany, Co Meath. That was also its highest daily rainfall for July in 61 years.

August heatwave verdict as Met Eireann surprises with new forecast
Ireland's summer so far has been a bit of a weather rollercoaster. From sweltering sunshine to sudden storms, we have experienced almost every season in the space of a few weeks. July turned out to be one of the warmest on record - the ninth warmest ever - however the start of August brought a big change. The recent bank holiday weekend was overshadowed by the arrival of an unusual summer storm, with Storm Floris wrecking havoc across the country. With schools still out and many hoping for one last run of summer sun, a lot of us have been wondering whether August will bring an official heatwave. Long-range weather models have recently been fuelling optimism, hinting at the return of high pressure. Some recent forecasts have even suggested temperatures could climb as high as 27C in parts of the country next week. Now it appears that there's a glimmer of hope on the horizon. Met Eireann has just released its latest monthly outlook, and in a surprise update, the national forecaster's new projections appear to be aligning with those optimistic models. It issued a new update for next week (August 11 to August 17) yesterday, saying: "This week is indicating high pressure dominating our weather. This will bring predominantly settled conditions with much drier than average conditions signalled across the country. Mean air temperatures in week 1 will be mild with temperatures above normal for the time of year." Weather models show highs of 29C are possible next Monday, August 18 (Image: High pressure systems are typically associated with calm, dry and warm weather - a welcome change after recent downpours. However, while this updated forecast hints at above-average temperatures and reduced rainfall, it's unlikely to meet the official criteria for a heatwave. Heatwaves are often defined as five days of consecutive above-average temperatures, but Met Eireann previously told the Irish Mirror: "That is a working definition used by some other met offices, but the Met Eireann definition of a heatwave is five consecutive days of temperatures above 25C." Looking further ahead into the second half of the month, there are still signs of settled weather and some heat. For the week of August 18 to 24, Met Eireann said: "While confidence this week is lower, there is a slight signal for high pressure to continue to dominate conditions, however, it looks to be shifting away slightly. In a primarily easterly airflow warmer than average temperatures will continue across the country, with a slight signal for below average rainfall too." For the final week of August, the outlook also remains cautiously positive. For the week of August 25 to 31, the forecaster added: "There is increasing uncertainty in the forecast for this week. There is little change indicated this week, with atmospheric pressure continuing to signal slightly above average. As a result, mean air temperatures are continuing to signal above average. The precipitation anomaly is also continuing to signal below average rainfall amounts for all areas." It's important to note that long-range weather maps, while useful, are notoriously subject to change, and even a slight shift can dramatically alter the outlook. The national forecaster explained: "The extended range forecast can at times provide an insight into weather patterns, however they have generally low skill because forecasts beyond one week become increasingly uncertain due to the chaotic nature of the atmosphere."

Hundreds of ESB customers in still without power following Storm Floris' 104kph wind gusts as worst hit area revealed
Storm Floris was the sixth named storm of the season. LIGHTS OUT Hundreds of ESB customers in still without power following Storm Floris' 104kph wind gusts as worst hit area revealed HUNDREDS of homes across Ireland remain without power following Storm Floris, which brought extreme winds and gales to the island over the bank holiday weekend. The storm, which made landfall in the early hours of Monday morning, impacted over 10,000 homes and businesses across the country. Advertisement 3 The storm, which received weather warnings in eight counties impacted over 10,000 homes and businesses across the island. Credit: Getty Images - Getty 3 Winds peaked at over 100km/h in parts of the country Credit: Getty Images - Getty Met Eireann said that the height of the storm saw average wind speeds of between 60kph and 70kph. On Malin Head in Inishowen, speeds reached 104kph. Several flights were cancelled in Northern Ireland due to the severity of winds. In Dublin airport, flight operations continued as usual, despite the cancellation of six flights by Emerald Airlines. Advertisement Tuam, Co. Galway, saw over 3,000 customers lose power, making it the worst area hit in the country. ESB Networks has said that as of this morning, 270 customers remain without power. Since Monday, a major repair campaign has been underway to reconnect all households, farms and businesses left without power. However, the vast majority of homes across the country have regained power since the storm. Advertisement The storm, which prompted weather warnings in eight counties, has been described as a "small weather event". Speaking on RTE's Morning Ireland, Senior Forecaster with Met Eireann, Gerry Murphy, said: "In the broader scheme of things, it's still a relatively small weather event". He added: "The main issue with this particular weather event is really the time of year and the weekend that it's occurring. Storm Floris hits with 90mph 'danger to life' wind set to wreak havoc – as thousands told do NOT travel "So in terms of its potential impacts, it had a greater weight than a wet, windy day perhaps in a non-bank holiday weekend or a non-tourist time of the year." Advertisement While Ireland may have escaped the worst effects of the storm, the same cannot be said of Scotland. SORRY SCOTLAND According to Scottish and Southern Electricity Networks, over 70,000 homes were left without power in Scotland due to storm Floris. As of this morning, 50,000 homes have had their power restored; however, 22,000 still remain powerless. Flights and rail services were also severely affected, with up to 119 incidents reported on rail lines and up to 68 departure flights thought to be cancelled in the UK as a result of the storm. Advertisement BETTER WEATHER In the wake of the bad weather, Met Eireann is predicting a warm and sunny week. Temperatures today will sit between 17C and 21C across the country. Tomorrow and Wednesday will see similar temperatures with "hazy sunshine" in the morning; however, clouds will thicken throughout the day. Over the coming weekend, temperatures are expected to remain relatively cool between 16C and 21C with occasional winds that will be stronger in the north and northwest. Advertisement On Saturday, conditions will be mostly dry and bright; however, on Sunday, showers and longer spells of rain are expected.
