Met Éireann predicts dry sunny weekend as Italy issues red heat alert

While Ireland enjoys a dry, mostly sunny spell that will keep temperatures in the low‑mid‑20s Celsius through the weekend, much of southern Europe is grappling with a blistering heat wave that has forced Italy to place all 27 of its major cities under the highest health warning. The contrast highlights how the same synoptic pattern can bring relief in one region and crisis in another, and why travellers and outdoor workers on both sides of the Channel need to adjust plans immediately.

Met Éireann’s short‑range outlook for Friday, Saturday and Sunday shows a gradual rise in daytime highs, peaking at around 24 °C in Leinster on Saturday. The service also notes isolated showers on Sunday before a clearer night. In Ireland the weather will stay comfortably mild, with nighttime lows staying above 8 °C in the south and 11 °C in the north.

Across the Alps, the European heat wave that has already shattered records in Austria, Slovakia and France is now pushing temperatures above 40 °C in Italy, prompting the Health Ministry to trigger a nation‑wide “red alert” – the first time that every city in the national heat‑surveillance network has been placed under the highest warning level simultaneously.

Both weather agencies attribute the extremes to a fast‑moving ridge of hot air that has stalled over central and eastern Europe. Italian officials describe the situation as “the first time this year that the entire network has been under the highest warning level.” Scientists cited by the Tribune India report warn that such events are becoming more frequent and intense as the climate warms.

What the forecasts say

• Friday (Ireland): Mix of cloud and sunshine, occasional light shower; highs 16 °C–24 °C, lows 8 °C–13 °C.
• Saturday (Ireland): Mostly cloudy in the west, dry sunny spells in Leinster and Munster; highs 16 °C–25 °C, lows not below 11 °C.
• Sunday (Ireland): Cloudy with rain moving southeastward, clearing later; highs 16 °C–24 °C, lows 9 °C–14 °C.
• Friday (Italy): Red‑alert temperatures exceeding 40 °C in all major cities, with record highs reported in neighboring Austria and Slovakia.
• Weekend (Italy): Continued extreme heat, health warnings for the entire population, and special measures at tourist sites.

The Irish forecast, detailed on Irish Examiner, also hints at a warm start to next week with highs nudging up to 25 °C on Monday and Tuesday, before humidity climbs on Wednesday. The Italian heat wave, however, shows no sign of easing, with temperatures in some valleys staying above 40 °C into Thursday.

Italy’s emergency response

Health officials have urged residents and visitors to avoid direct sunlight during peak hours, stay indoors where possible, and keep hydrated. The ministries of tourism and culture have extended evening opening hours at landmarks such as the Colosseum and the Pantheon, installing cooling mist fans at entrances and additional medical stations.

Rome has gone a step further, launching a free municipal “urban beach” along the Tiber River called Tiberis. The site offers swimming pools, water fountains and shaded sections for families seeking relief from the scorching streets.

"It is excellent, it is a great initiative. They did the right thing, specially with such hot days it is important to cool down with water, specially for children."

Broader European ripple effects

The heat wave is also straining infrastructure beyond Italy. In Hungary, the Danube’s low water level forced the country’s sole nuclear plant to slash output to roughly one‑tenth of normal production, prompting electricity‑saving measures such as reduced lighting on Budapest’s landmarks and a ban on freight trains during peak hours. Slovakia’s record 42.2 °C temperature triggered the shutdown of seven of eight turbines at the Gabcikovo hydroelectric plant due to insufficient river flow.

France’s Var region continues to battle a massive wildfire that has already consumed more than 60 km². Strong winds and extremely dry conditions keep the area at high risk for new ignitions, while Germany warns that drought‑lowered river levels could disrupt inland shipping and industrial water supplies.

Even the United Kingdom is feeling the after‑effects of July’s driest month on record. A grass fire briefly closed a runway at Heathrow, underscoring how heat can impact transport hubs far from the continent’s core.

What to watch next

• Next Monday’s Met Éireann outlook – a return to mostly dry conditions with highs of 17 °C–22 °C.
• Potential extensions of evening opening hours at key tourist sites as heat persists.

For Irish readers planning weekend trips, the forecast means clear skies for coastal walks and outdoor cafés, but the lingering risk of Sunday showers advises packing a light rain jacket. Meanwhile, travelers heading to Italy should heed health advisories, stay out of direct sun during mid‑day, and consider visiting cooling installations such as Rome’s Tiberis “urban beach.”

As Europe wrestles with an unprecedented heat wave, the juxtaposition of Ireland’s mild sunshine and Italy’s red‑alert temperatures illustrates the uneven impacts of a shifting climate. Monitoring the evolving forecasts and official guidance will be essential for anyone moving between the temperate west and the increasingly volatile south.
