On Thursday, 9 April, a wave of hot, dry air will move across the country, raising temperatures by 12 to 15 °C in just 24 hours, according to Tempo.pt.

The portal reports that the North and Central regions will be hit hardest, with some areas expected to see unusually high summer temperatures near 30 °C.

This sudden warming requires people to quickly adjust their daily routines, especially when it comes to staying healthy during these big temperature swings. Recently recorded highs of only 9 °C are expected to reach 22 °C, while Braga could reach 27 °C.

In addition to the heat, winds from the southeast are bringing dust from Africa. This dust will make the sky look hazy and could lower air quality. Particulate matter requires extra caution for at-risk groups and athletes, as visibility and air quality will be affected across much of the country.

However, this "early summer" is brief, and it will not be the same everywhere. Inland areas may reach close to 30°C, but the Algarve will stay cooler, around 15°C, thanks to the sea and local weather patterns.

A drop is forecast, bringing values closer to seasonal norms.

This abrupt shift underscores the need for citizens to monitor weather reports and adapt quickly to changing conditions.
