European heatwave: Where hot weather alerts are in force

A persistent heat dome over western and central Europe is driving temperatures into the high 30s and low 40s Celsius, prompting hot weather warnings across popular holiday destinations and raising fresh concerns about the risks for residents and summer visitors.

United Kingdom and Ireland: Prolonged hot spell triggers alerts

Across the United Kingdom, national forecasters report an unprecedented run of days above 35 degrees Celsius, with heatwave conditions now stretching from southern England into Wales and parts of Scotland. Heat-health alerts and weather warnings highlight the danger of sustained high daytime temperatures combined with very warm nights that offer little relief.

Publicly available information from the Met Office describes a prolonged spell of hot, settled weather expected to continue into next week, with temperatures widely in the low to mid-30s and higher in some inland areas. Transport operators are preparing for possible rail disruptions, road surface damage and increased wildfire risk in parched countryside.

In Ireland, the national meteorological service has issued yellow hot weather warnings for several counties, noting a prolonged period of very warm or hot conditions. Advisories point to uncomfortable sleeping conditions, heat stress for vulnerable people, and elevated fire danger in rural areas. Tourists planning coastal walks, city breaks in Dublin or road trips along the Wild Atlantic Way are being urged to plan activities for cooler parts of the day and to watch for updated forecasts.

For travellers, the combination of packed summer events, busy airports and heat warnings means extra time should be built into journeys. Visitors are being encouraged to check rail and air travel updates frequently, as high temperatures can affect infrastructure and lead to short-notice timetable changes.

France and Spain: Extreme heat in key holiday regions

In France, forecasters describe a new episode of intense heat building across much of the country after an already hot start to the summer. Recent updates from Météo-France highlight very high daytime temperatures, hot nights and a pattern of blocking high pressure systems that have repeatedly parked over western Europe since May.

High heat alerts cover parts of southwestern and southern France, including regions in Occitanie, Nouvelle-Aquitaine and the Rhône valley that are magnets for beach and countryside tourism. In some areas, daytime temperatures are forecast in the mid to high 30s Celsius, with local peaks even higher in enclosed valleys and urban centres. Public guidance stresses the risk of heat stress for older adults, young children and people with pre-existing health conditions, and notes the potential for wildfires in dry forests and scrubland.

Spain is enduring another intense heatwave, with the national meteorological agency extending special heat alerts over wide swathes of the country. Reports indicate that orange and yellow warnings cover large areas of Andalusia, Extremadura, Castilla-La Mancha and the Ebro basin, with temperatures around 40 degrees Celsius and even higher in some inland locations.

On the Atlantic and northern coasts, usually cooler destinations are also facing unusually high temperatures, with beach towns in the Cantabrian region under heat advisories. Travellers heading for city breaks in Madrid, Seville or Valencia are being reminded that many streets and squares offer limited shade in the afternoon, while rural visitors are being cautioned about wildfire risk and restrictions on access to some natural parks.

Italy, Balkans and eastern Mediterranean: High heat and fire risk

Across Italy, publicly reported forecasts show temperatures commonly in the mid-30s and higher, with national and regional bulletins flagging hot weather alerts in several major cities. Northern plains such as the Po Valley, as well as central and southern regions including Lazio, Campania, Puglia and Sicily, are seeing extended stretches of very warm days and sticky nights.

Authorities have activated standard summer heat contingency plans, including public information campaigns encouraging people to limit outdoor activity during peak heat, stay hydrated and check on vulnerable neighbours. Popular tourist destinations such as Rome, Florence and Venice are reporting busy streets even as local services advise visitors to avoid queuing in full sun during the middle of the day.

In the Balkans and parts of the eastern Mediterranean, including Croatia, Greece and some countries further east, national meteorological services have issued high-temperature warnings and wildfire risk notices. Coastal resorts along the Adriatic and Aegean seas, usually favoured for sea breezes, are recording temperatures in the mid to high 30s, while inland valleys and city centres can feel hotter still.

Wildfire bulletins point to very dry vegetation and gusty winds in some areas, increasing the likelihood of rapidly spreading fires if ignition occurs. Visitors planning hikes, wild camping or visits to national parks are advised to monitor local fire risk maps and to follow any restrictions on barbecues, campfires and access to high-risk zones.

Central and northern Europe: Heat alerts reach less typical hotspots

The current heatwave is not confined to the Mediterranean. Publicly available information compiled by European agencies shows large areas of central and northern Europe also experiencing unusual, and in some cases record-breaking, temperatures accompanied by hot weather advisories.

In Germany, weather services have issued heat warnings for parts of the west and south, where temperatures are pushing into the mid-30s, particularly along the Rhine valley and in major urban centres. Similar conditions are reported in Belgium, which has recently escalated its heat alert level, and in the Netherlands, where high temperatures combine with humidity to create uncomfortable conditions in densely populated coastal regions.

Poland, the Czech Republic, Austria and Hungary have also reported periods of intense heat this summer, with local warnings activated when thresholds are reached. In some cities, temporary cooling centres, shaded public spaces and extended opening hours for swimming pools are being used to provide respite from the heat, even as tourism numbers remain strong.

Further north, parts of Scandinavia are experiencing warmer than usual conditions, though not always at the extreme levels seen in southern Europe. Nonetheless, prolonged sunny spells and above-average temperatures are raising concerns about wildfire risk in forests and peatlands, particularly in Sweden and Norway, and prompting local advice for residents and visitors to stay alert to changing conditions.

How travellers can respond to evolving hot weather warnings

The World Health Organization’s European office has recently underlined that the region remains vulnerable to extreme heat, noting that heatwaves can cause sharp spikes in illness and mortality within days when temperatures climb and do not fall sufficiently at night. Public health guidance emphasises the importance of paying attention to national meteorological warnings and acting quickly when hot weather alerts are issued.

For travellers, that means checking the official forecasts and warning maps of the country they are visiting every day, rather than relying solely on long-range outlooks made before departure. Many national meteorological services operate tiered colour-coded alert systems, from yellow advisories for unusually warm conditions to orange and red warnings indicating dangerous heat with heightened health risks.

Visitors are encouraged to adjust their itineraries when alerts are in place, shifting sightseeing, hikes or outdoor sports into the early morning or late evening. Midday hours can be reserved for shaded or indoor activities such as museum visits, rest periods in air-conditioned spaces, or travel between destinations. Travel insurers and tour operators increasingly reference official heat warnings when advising customers about potential itinerary changes.

Basic precautions remain central to staying safe in the European heatwave: drinking plenty of water, wearing light clothing, using high-factor sun protection, and knowing the signs of heat exhaustion and heatstroke. For those travelling with young children, older relatives or people with medical conditions, extra planning and vigilance are advised, especially in destinations currently subject to the highest hot weather warnings.
