IPMA forecasts rain and temperature drop across mainland
The Portuguese Institute for Sea and Atmosphere (Instituto Português do Mar e da Atmosfera or IPMA) has issued a warning for a prolonged period of rain, thunderstorms, and falling temperatures across mainland Portugal. This shift follows an unseasonably warm Easter period and is caused by a depression moving between the Madeira archipelago and the mainland. Temperatures are expected to drop, with minimums ranging between eight and 12 degrees Celsius.
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.
