Next week we will see a “true rollercoaster of rising and falling temperatures”
Return of rain and even thunderstorms: a "temperature rollercoaster" is on the way

Context & Explainers

IPMA (Instituto Português do Mar e da Atmosfera) is Portugal's national authority for weather, ocean, and climate monitoring. It produces weather forecasts, issues severe weather warnings, monitors seismic activity, and provides marine and atmospheric data.
IPMA uses a four-level color-coded warning system: green (no risk), yellow (potential risk), orange (moderate-to-high risk), and red (extreme risk). These warnings cover conditions such as heavy rain, strong winds, extreme heat, cold snaps, rough seas, and snow.
Residents should monitor IPMA forecasts during storm season (typically October–March) and heatwaves (July–August). IPMA bulletins are used by civil protection authorities, transport operators, and local councils to make decisions about road closures, school suspensions, and evacuation orders.
