Between June 15 and 18, mainland Portugal will be affected by a combination of weather systems, including a high-pressure area located south of the British Isles and a low-pressure trough stretching from North Africa to the Iberian Peninsula. This atmospheric setup is expected to bring a notable rise in temperatures, particularly on Sunday and Monday.
During this period, a new episode of suspended dust originating from North Africa is also anticipated. Daytime temperatures across most of the country are forecast to range between 33 and 40 degrees Celsius, with slightly cooler conditions along some coastal areas. The highest temperatures are likely to be recorded in regions such as the Tagus Valley, Beira Baixa, and the southern part of the country.
The warm conditions may persist until June 19, especially in inland areas. Minimum temperatures are also expected to rise on June 16 and 17, with a likelihood of tropical nights, where temperatures remain high even after sunset, affecting much of the mainland.
Health authorities are advising the public to stay hydrated, wear lightweight and breathable clothing, and apply sunscreen every two hours. They also recommend avoiding sun exposure between 11 a.m. and 5 p.m., and paying particular attention to the needs of vulnerable individuals such as the elderly, children, and those with chronic illnesses. These groups should remain in cool, shaded areas whenever possible.
The suspended dust from the Sahara can negatively impact air quality and pose health risks, especially to sensitive populations. To reduce exposure, people are advised to avoid intense physical activity outdoors, limit time spent outside, and steer clear of potential irritants like tobacco smoke. The public is encouraged to take extra precautions while this weather pattern and air quality issue continue.
