After a start of September marked by high temperatures and new heat records in several regions of the country, the weather in Portugal will undergo significant changes on Wednesday, September 9th. According to the forecast from the Portuguese Institute of the Sea and the Atmosphere (IPMA), rain should return to the mainland, concentrating mainly in the Centro region, where periods of light rain are expected until mid-morning.
Precipitation is not expected to affect the entire national territory, and in the rest of the country the main feature will be cloudiness in the early hours of the day. From mid-morning onwards, the trend is for a gradual improvement in weather conditions, with the sky becoming partly cloudy or even clear. Generalised rain is not forecast for mainland Portugal.
The rain will be accompanied by a small drop in maximum temperatures, which should be felt in the interior of the Norte and Centro regions and also in the Sul region. This decrease represents a change from the high values that marked the beginning of September, although it should not be pronounced. The wind will also gain strength, blowing from the north between 30 and 40 km/h on the western coastal strip from the afternoon onwards.
In the Madeira archipelago, the scenario will be different, since no rain is forecast for Wednesday. The sky should be partly cloudy or clear, although greater cloudiness may appear on the north slope and in the highlands. Here too, maximum temperatures will register a small drop, more evident in the highlands.
