Portugal is sweltering under an intense heatwave this St Anthony's Day, with temperatures forecast to hit 45°C in parts of the country. The national holiday, traditionally marked by festivities and street parties, has instead driven residents and tourists alike toward the cooler Atlantic shores.
The Portuguese Institute of the Sea and the Atmosphere (IPMA) has issued red alerts for several districts, including Santarém, Évora, and Beja, where the mercury is expected to peak. In Lisbon, temperatures are hovering around 40°C, prompting the city to open cooling centers and extend beach hours.
A National Day Under the Sun
St Anthony's Day, celebrated on 13 June, honors Lisbon's patron saint and is a public holiday in the capital. This year, the usual parades and sardine grills have been tempered by the extreme heat. Health officials are urging caution, particularly for the elderly and those with pre-existing conditions.
“We recommend staying indoors during the hottest hours, drinking plenty of water, and avoiding strenuous activity,” said a spokesperson for the Portuguese Directorate-General of Health. The warning comes as emergency services report a spike in heat-related calls.
The heatwave is part of a broader pattern affecting southern Europe. Greece, Spain, Italy lead summer 2026 travel surge as Southern Europe gains, but the current conditions are testing infrastructure and public health systems.
Climate Context and Comparisons
This event follows a mid-summer heatwave in Spain that brought July-like temperatures earlier this month. Scientists warn that such extremes are becoming more frequent due to climate change. A recent study highlighted that the Earth is on track to breach the 1.5°C warming threshold by 2030 if emissions persist, a scenario that would amplify heatwaves across the continent.
Portugal's experience mirrors that of other Mediterranean nations. In 2023, the country recorded its hottest year on record, and this year's early heat is raising concerns about water scarcity and wildfire risk. The IPMA has warned that dry conditions could fuel blazes, particularly in the central and southern regions.
For now, the focus remains on coping with the immediate heat. Beaches from Cascais to the Algarve are packed, and air-conditioned shopping centers have become makeshift refuges. The government has activated a national heat plan, coordinating with local authorities to check on vulnerable populations.
As Europe braces for what could be another scorching summer, Portugal's St Anthony's Day serves as an early reminder of the challenges ahead. The country's ability to adapt—through better urban planning, early warning systems, and public awareness—will be tested in the coming months.
