Summer season heatwaves are altering journey—this is what you should know

For seasoned travellers Heike and Robert Taylor, Umbria in the summertime of 2022 was a turning level. The couple’s reminiscences of a stress-inducing journey to the Loire Valley in July 2019 — when the area sweltered in 40C warmth — have been nonetheless uncooked, however they’d persevered with reserving an Italian villa for a giant household reunion. By nature, the Taylor clan on vacation are explorers. Yet such was the ferocity of the heatwave afflicting the central Italian area that summer time, they ended up hardly ever leaving their rental property. “What was really eerie was lying by the pool and seeing the smoke in the distance from the wildfires, and helicopters flying in to douse the flames. I don’t think I’ll ever forget that,” says Heike.

Returning residence, the couple vowed by no means once more. Now, peak summer time is spent in and round their Surrey residence — and the European shoulder-season months of May and September are given over to lively breaks within the likes of Sicily and Corsica.

It’s an all-too-common sample amongst travellers, as heatwaves have shifted from uncomfortable anomalies to extremely disruptive, near-annual occasions. The summer time of 2022 was significantly excessive, with an estimated 60,000 heat-related deaths in Europe, China wilting within the face of an unprecedented 70-day heatwave and, in July, components of the UK topping 40C for the primary time. The identical month the next yr, practically 20,000 folks — a lot of them travellers — needed to be evacuated from the Greek island of Rhodes attributable to heatwave-exacerbated wildfires.

Heatwaves are spreading throughout the calendar, too. In May 2022, Spain’s state meteorological company Aemet reported a heatwave of ‘extraordinary intensity’, with temperatures as much as 15C above the seasonal common. In 2023, extreme warmth in France prolonged into September, affecting the operation of the Rugby World Cup. Earlier this yr, a lot of the southwestern US was hit by a March heatwave, with temperatures touching 43C in components of Arizona. As António Guterres, the UN secretary common, put it: “Extreme heat is no longer a rare event — it has become the new normal.”

In statistical phrases, there’s no common definition of a heatwave; there’s merely an excessive amount of variance in international temperatures. But in all circumstances it refers to a interval of abnormally excessive temperatures lasting for consecutive days. The UK’s Met Office defines it as no less than three days the place every day most temperatures exceed a regional threshold. In London that’s 28C. In Scotland, 25C. Both can be thought of delicate for someplace like Athens.

With human exercise ‘unequivocally’ driving international warming and the rise in such excessive climate occasions, based on the United Nations’ Intergovernmental Panel on Climate Change, the scenario will solely worsen. “We are pretty certain that for the next decades, at least, if not centuries, it’s going to be hotter and hotter,” says Alejandro Saez Reale, a specialist in heatwaves and their influence on the World Meteorological Organization in Geneva. “The impact on tourism-reliant countries could be huge.”

Europe finds itself on the epicentre of heatwave-related tourism challenges. It’s the fastest-warming continent on Earth, based on the World Meteorological Organization, and in addition probably the most visited, with France, Spain, Italy and Greece persistently on this planet’s high 10 locations. The more and more common time period ‘coolcation’ neatly summarises the rising development for travellers throughout the continent searching for out extra temperate spots.

Northern and jap European locations are among the many quickest rising in tourism phrases, based on a report by the European Travel Commission (ETC), with Finland, Norway, Poland and Iceland all recording double-digit development in inbound guests. Research by the ETC in 2025 discovered 81% of Europeans have been adjusting their journey habits because of the altering local weather, with 15% actively searching for out cooler climates and 14% avoiding locations susceptible to excessive warmth. Travel operators equivalent to TUI and Thomas Cook additionally report rising demand for Nordic nations.

Yet in 2025, France (102 million) and Spain (96.8 million) have been nonetheless probably the most visited nations on this planet, based on UN Tourism; Italy was fifth (64.5 million). The development charge might have slowed, however the variety of guests to those nations just isn’t dropping.

The Association of British Travel Agents (ABTA) is sceptical heatwaves have the capability to redraw the tourism map, no less than within the short-term. “Feedback from our members suggests that, on the whole, people are continuing to travel much as they always have, enjoying Mediterranean destinations during the summer months,” stated a spokesman. “Increased interest in slightly cooler destinations remains the exception rather than the norm.”

There are large incentives for tourism-dependent locations to make sure heatwaves don’t end in a journey exodus. This is driving improvements that, in time, may turn out to be widespread. Seville, in part of Spain often called the ‘Iberian oven’ due to the winds that blow up from North Africa, is the epicentre of one of many world’s most heatwave-afflicted nations. Sevillanos are used to elaborate warmth mitigation measures. These embrace rainwater-fed water-misting methods in excessive footfall areas; a community of underground, aqueduct-style chambers that may decrease ambient temperatures at road degree by as much as 9C; street-spanning awnings; and ‘urban cool islands’— sanctuaries of dense vegetation which might be deployed right here and in Los Angeles, Singapore, Paris and dozens of different cities.

Attractions such because the Royal Alcázar of Seville shifting to night opening instances is one other commonsense measure. The idea of ‘noctourism’ — exploration after darkish, partially to mitigate excessive daytime temperatures — is being embraced all over the place from Rome’s Colosseum to the Acropolis in Athens, which has confronted common closures in excessive summer time attributable to current heatwaves.

Arcas Travel Services, which runs excursions in Greece, says it has began to push its archaeology-themed journeys into the shoulder seasons attributable to heat-related closures of key websites. Meanwhile, the corporate’s biking excursions are being tailor-made in direction of early begins and earlier finishes. Often it’s the operator reasonably than travellers taking the lead, highlighting one of many key considerations: the lack of understanding across the risks of maximum warmth.

Dr Mehri Khosravi is a warmth skilled on the University of East London and grew up in Tehran, the place temperatures of 40C-plus will not be unusual. She says a part of the issue is the absence of a “culture of heat” amongst guests to heatwave-affected areas — these societal and behavioural diversifications that cowl the whole lot from clothes to the pacing of the day. “The perception is still that heat is a desirable thing,” she says. “Behaviour [in tourism] is going to have to adapt and the key to that is risk communication.”

The rising accuracy of long-term forecasting is a substantial asset on the subject of local weather occasion alerts. Saez Reale believes it’ll turn out to be more and more frequent for meteorological companies to liaise with tourism our bodies about excessive climate, in the best way they at the moment do with well being authorities. Travellers reserving later and embracing flexibility in each the place and when their holidays happen is one other anticipated development. “The good news is that there’s an awful lot that can be done,” he says.

Upsides in heatwave-driven adjustments to tourism patterns are actually attainable to discern. One is the potential for a extra even distribution of travellers each geographically and seasonally; tourism places immense pressure on native sources equivalent to water and healthcare — significantly in instances of sustained warmth. Investment in climate-resilient infrastructure to allay traveller considerations has a transparent profit to native populations, too.

But the largest optimistic, says Jenny Southan, CEO of journey development forecasting company Globetrender, could also be one among outlook. “Travellers are becoming more climate-conscious, even if there’s an inherent tension between the desire to explore and the environmental cost of doing so. Climate pressure may act as a catalyst for a more thoughtful, intentional era of travel.”

For shoulder-season converts Heike and Robert Taylor, heatwaves might have altered the construction and rhythm of their yr, however not essentially for the more serious. “Going away earlier or later in the year, rather than in the summer peak, you can get a more authentic sense of what a place is really like,” says Heike.
