Europe’s “Tropical Nights” Become a Sweaty Reality: Health, Travel, and Climate Impacts
“Tropical nights” might conjure images of idyllic beach parties and refreshing cocktails, but the emerging reality across Europe paints a far less appealing picture. Since the 1980s, these nights, defined by temperatures stubbornly refusing to dip below 68°F (20°C), have become increasingly common, bringing with them a host of disruptions to daily life and even vacation plans.
In 2024, popular summer destinations in Southern Europe, including Italy, Croatia, Turkey, and Greece, endured a record-breaking 23 tropical nights, according to recent data. This trend isn’t just an inconvenience; it’s an indicator of a broader climate shift with serious implications.
Imagine trying to sleep in sweltering heat, sheets sticking to your skin, and opening the windows offering no relief. This is the reality for manny Europeans during these increasingly frequent tropical nights.
Nighttime temperatures are “really crucial for our health” because it’s the part of each day when we recover. And if it can’t do that, it brings a “whole host of issues.”

These stifling conditions occured during what was officially the hottest year on record for Europe. However, experts emphasize that this isn’t a one-off event. Climate change is steadily raising atmospheric temperatures, contributing to both daytime and nighttime heat stress.
Last year also saw 66 days of “strong heat stress” across Southern Europe, where daily temperatures felt like 90°F (32°C) or higher, considerably exceeding the average of 29 days. This combination of extreme heat during both day and night is pushing the limits of human comfort and well-being.
The Hidden Costs of Sleepless Nights
The escalating daytime highs coupled with unrelenting nighttime heat are taking a toll on human health.
Europe is heating up, and we’re not prepared for the toll this will take on our health…Deaths from heat stress are the most visible impact. But extreme heat doesn’t just kill – it also increases the risk of heart disease, pregnancy complications, and poor mental health.

Children are especially vulnerable due to their smaller size, which causes them to heat up more quickly. Pregnant women, whose bodies already struggle with temperature regulation, also face increased risks.
Similar heat waves in the U.S. have highlighted the importance of public health infrastructure.For instance, during the 1995 Chicago heat wave, over 700 deaths were attributed to the extreme temperatures, exposing vulnerabilities in the city’s emergency response systems and disproportionately impacting low-income communities.
Beyond Human Health: Impacts on Agriculture and Infrastructure
The consequences extend far beyond human health, impacting critical sectors like agriculture and infrastructure. In 2024, wine harvests were significantly reduced, with industry insiders describing the yields as “dismal” and “horrible.” Olive trees suffered from intense heat and drought, while roads in Italy literally melted under the scorching sun. A wildfire near Athens consumed nearly 27,200 acres (110 square kilometers).
These events echo similar challenges faced by American farmers. the California drought, such as, has decimated crops and forced farmers to implement innovative irrigation techniques to conserve water.Similarly,extreme heat in the Southwest has stressed infrastructure,leading to power grid failures and water shortages.
The Travel Industry Responds
The travel industry is already adapting to this “new reality.” Intrepid Travel,for example,has canceled hiking tours in Turkey during the hottest months of July and August. Instead, they are promoting summer trips to Scandinavia, which have seen a 40% increase in bookings from British travelers.
Online search trends reflect this shift. Google reported a surge in searches for terms like “summer holiday in Europe not too hot” and “what summer holiday destinations do not have risk of wildfires in July.”
This trend mirrors the increasing popularity of “shoulder season” travel in the U.S., where travelers seek milder temperatures and fewer crowds by visiting destinations in the spring or fall.
Looking Ahead: A Hotter Future for Europe
The extreme summer of 2024 may have been a record-breaker, but it is indeed indicative of a long-term warming trend, according to Copernicus.Europe is the fastest-warming continent, heating up twice as quickly as the global average, partly due to its proximity to the arctic.
Even though scientists can’t predict the precise number of tropical nights or heat waves expected this year, they are confident that the overall trend is towards a hotter future.
We urgently need to cut emissions and adapt our cities. Simple changes, like adding green spaces and waterways, can help cool urban areas and protect public health.
Madeleine Thomson,head of climate impacts at Wellcome
This call to action resonates strongly in the U.S., where cities are implementing similar strategies to combat the urban heat island effect.Initiatives like planting trees, creating green roofs, and using reflective pavements are gaining traction as cities strive to mitigate the impacts of rising temperatures.
Adapting to the Heat: practical Tips for U.S. Readers
While the article focuses on europe, the implications of rising temperatures affect everyone. here are some practical tips for U.S. readers to prepare for and cope with extreme heat:
- Stay hydrated: Drink plenty of water throughout the day, even if you don’t feel thirsty.
- Limit outdoor activities: Avoid strenuous activities during the hottest parts of the day. If you must be outside, take frequent breaks in the shade.
- Wear light-colored, loose-fitting clothing: This helps your body stay cool.
- Use air conditioning or fans: If you don’t have air conditioning, consider visiting a cooling center or public library.
- Check on vulnerable neighbors and relatives: The elderly, young children, and peopel with chronic illnesses are particularly susceptible to heat stroke.
By understanding the challenges posed by rising temperatures and taking proactive steps to adapt, we can protect our health and well-being in a warming world.
