LONDON — A prolonged heatwave and dry spell across Europe has forced thousands of evacuations in France and Greece, strained firefighting resources and pushed parts of the United Kingdom deeper into drought, threatening tourism, agriculture, utilities and transport during the peak summer season.

Emergency services in southern Europe have been battling fast-moving wildfires driven by high temperatures, low humidity and dry vegetation. Authorities have ordered residents and holidaymakers to leave exposed areas, disrupting hotels, campsites, road networks and local businesses that rely on August travel demand.

The business impact is widening beyond the immediate fire zones. Tourism operators face cancellations and rerouting costs, farmers are contending with stressed crops and higher irrigation needs, and insurers are assessing the risk of larger claims from property damage, business interruption and emergency accommodation.

In the United Kingdom, water scarcity has become a growing operational concern for agriculture, food producers and water utilities. The U.K. Environment Agency has warned that dry conditions are putting pressure on rivers, reservoirs and groundwater levels after sustained heat and limited rainfall.

“The current situation is nationally significant and we are calling on everyone to play their part and help reduce the pressure on our water environment,” said Helen Wakeham, director of water at the U.K. Environment Agency and chair of the National Drought Group.

For companies, the heatwave adds another weather-related cost shock after years of supply-chain volatility and rising insurance premiums. Logistics firms can face delays when roads are closed by fires or heat damage, while rail operators often impose speed restrictions when tracks become vulnerable to buckling.

Energy markets are also exposed. Hot weather can lift electricity demand as households and businesses increase air-conditioning use, while drought can reduce hydropower output and limit cooling water availability for some thermal and nuclear plants. That combination can tighten power systems and raise short-term prices in affected regions.

Agriculture is one of the most exposed sectors. Prolonged heat can reduce yields for grains, fruit and vegetables, while livestock producers face higher feed, water and cooling costs. Lower output can feed through to food processors and retailers if shortages become severe or persistent.

France and Greece are particularly vulnerable because summer tourism is a major contributor to local employment and revenue. Evacuations during the holiday peak can hit restaurants, hotels, transport providers and small retailers even when physical damage is limited, as visitors avoid affected regions.

The latest fires also underscore the rising fiscal burden on governments. Firefighting aircraft, emergency shelters, disaster payments and infrastructure repairs require public spending at a time when many European governments are already managing tight budgets and higher debt-servicing costs.

Climate scientists and risk analysts have warned that hotter, drier summers are increasing the probability of severe wildfire seasons in parts of Europe. For investors, that is making physical climate risk a more material factor in valuations for utilities, real estate, agriculture, insurance and travel-related companies.

Businesses are likely to face growing pressure to adapt operations, from revising continuity plans and hardening facilities to securing backup water and power supplies. For many sectors, Europe’s summer heat is no longer only a public-safety event; it is becoming a recurring balance-sheet risk.
