Heatwaves in Cyprus and the Eastern Mediterranean: Rising Temperatures and Their Impacts
The summer of 2025 has once again highlighted how vulnerable Cyprus and the Eastern Mediterranean are to extreme heat. Prolonged periods of unusually high temperatures are being recorded across the region, with maximum values reaching or even surpassing 42–44°C in parts of Cyprus.
Forecasts at the 850 hPa level (around 1,500 m above sea level) show anomalies of up to +10 to +12°C compared to the 1991–2020 climate average—a clear indication that recent events stand well outside the norms of past decades.
Such conditions are not isolated. Heatwaves in Cyprus increasingly occur earlier in the season, last longer, and reach higher intensity, reflecting global and regional warming trends.
Cyprus Under Heat Stress
In recent years, Cyprus has experienced record-breaking summer heat events, with several consecutive days above 40°C, particularly inland. Coastal regions also face extended periods of high nighttime temperatures, offering little relief from the daytime heat.
This sustained heat has serious local impacts:
-
Nicosia and inland plains often record the highest maximums, pushing close to or above 44°C.
-
Coastal cities such as Limassol and Larnaca experience high humidity alongside elevated temperatures, amplifying the discomfort and health risks.
-
Mountain areas provide relative relief, but even Troodos frequently registers unusually high temperatures compared to historical averages.
Why Do Heatwaves Affect Cyprus So Strongly?
Cyprus lies at the crossroads of Europe, Asia, and Africa, directly influenced by hot air masses from North Africa and the Middle East. When these combine with strong high-pressure systems over the Mediterranean, they trap warm air and lead to extreme surface temperatures.
Climate change is making these events more frequent, longer, and more severe, with local records being approached or broken almost every summer.
Expected Impacts for Cyprus
Heatwaves affect multiple sectors of life on the island:
-
Human health risks: Increased cases of dehydration, heat stress, and heat-related illness. Vulnerable groups such as the elderly, children, and outdoor workers are most at risk.
-
Energy demand: Higher use of air conditioning places strong pressure on the national grid, especially during peak demand hours.
-
Agriculture: Crop yields and livestock health are negatively impacted, while prolonged dryness increases the risk of wildfires, as seen in the recent Limassol fire.
-
Water resources: High evaporation rates intensify water scarcity, a long-term challenge for Cyprus.
Preparing for the Heat
Adapting to more frequent and severe heatwaves requires both immediate actions and long-term planning.
-
Short-term protective measures include staying hydrated, avoiding outdoor activity during peak heat hours, seeking cooler indoor spaces, and checking on vulnerable neighbors.
-
Early warning systems—such as those provided by the Copernicus Climate and Atmosphere Services—are crucial to alert citizens in advance.
-
Long-term adaptation strategies involve urban greening, heat-resilient infrastructure, and improved water management.
The ERATOSTHENES Centre of Excellence, together with European initiatives like Copernicus, works to monitor temperature anomalies and provide scientific support to decision-makers in Cyprus. These tools are vital for reducing risks and protecting both people and the environment.

This image, a mosaic from five overlapping orbital passes in the morning of 29 June 2025, was captured by the Copernicus Sentinel-3 mission’s Sea and Land Surface Temperature Radiometer. As the instrument’s name suggests, the image reveals the temperature of the land surface, not air temperature. Unlike measurements of air temperature, this satellite instrument measures the actual thermal energy emitted from Earth’s surface, which typically registers higher than air temperatures.
