Hot Weather Alert Across Portugal: Coastal Regions to Experience Moderate Temperatures
Portugal is bracing itself for a prolonged heatwave, with the Portuguese Institute for Sea and Atmosphere (IPMA) predicting severe hot weather until at least August 6. The forecast affects several regions, including Setúbal, Lisbon, and Santarém [1][2].
The IPMA's forecast reveals that maximum temperatures in Setúbal and Lisbon will range between 28°C and 36°C, making them comparatively cooler than inland areas like Santarém, which can expect temperatures up to 40-44°C [1]. From August 2 to August 5, these temperature ranges will persist, with a gradual decrease expected thereafter [1].
Nighttime temperatures, or "tropical nights," are also on the rise, with nighttime lows remaining between 20 and 25°C across most of the territory [1][2]. However, by midweek, these tropical nights may become limited to the interior regions.
In Madeira, a yellow warning is in effect due to the heat. Contrary to the mainland, the coastal strip of Madeira, including the South Coast, is not under this warning. Instead, the warning applies to the mountainous regions [3]. Clear skies and sometimes strong winds are expected in Madeira, but the yellow warning is set to expire at 6:00 pm today [3].
Regarding wind conditions, moderate winds might be expected along coastal regions, but no severe wind events are indicated in the IPMA's publicly reported forecasts [1][2].
In conclusion, Setúbal and Lisbon, being coastal regions, will experience hot but somewhat moderated temperatures, while Santarém inland will likely reach higher maximums closer to 40-44°C. Meanwhile, Madeira's coastal strip, excluding the mountainous regions, will not be affected by the yellow warning for heat [1][2][3].

In the context of the heatwave in Portugal, the science of weather forecasting by the Portuguese Institute for Sea and Atmosphere (IPMA) predicts that Setúbal and Lisbon, as coastal regions, will experience moderated temperatures, ranging between 28°C and 36°C, while the environmental science of thermodynamics explains why these temperatures are cooler compared to inland areas like Santarém. The weather-forecasting of the IPMA further reveals the use of environmental-science concepts in predicting tropical nights, with nighttime lows between 20 and 25°C across most of the territory.
