After several days of unusually mild temperatures across Spain, the almost spring-like conditions are drawing to a close. A new weather system arriving at the start of the week is expected to bring a marked shift — with rainfall, thunderstorms and the arrival of a phenomenon unfamiliar to many newcomers: mud rain.
On Monday, a weather front will move across the Iberian Peninsula from the west. While the first showers are expected to reach north-western areas in the morning, the system will gradually spread inland and southwards as the day progresses.

Rain Mixed with Saharan Dust
What makes this episode distinctive is the combination of moist Atlantic air with a mass of dust-laden air arriving from North Africa. As the rain falls through this layer of suspended Saharan dust, it can turn into what is commonly referred to as “mud rain”.
Though not unusual in Spain, this phenomenon often comes as a surprise to international residents and visitors. Within hours, vehicles, terraces and outdoor surfaces may be coated in a thin layer of brown residue.
Storm Risk Increases
As the system advances, rainfall is expected to intensify in parts of the country, with locally heavy downpours possible later in the day. Thunderstorms may also develop in some areas as atmospheric instability increases.
Parts of Andalusia — including provinces such as Seville, Huelva, Cádiz and Málaga — are expected to see locally heavy rainfall overnight.
Unsettled Conditions Continue
The instability is expected to persist into Tuesday with the formation of a DANA — a high-altitude cold air pocket known for triggering prolonged rainfall events.
Further rain is likely to follow midweek, as a developing low-pressure system maintains unsettled conditions across large parts of the country. Additional showers and thunderstorms cannot be ruled out in the days ahead.
Early forecasts suggest that this period of changeable weather could extend into Thursday, marking a return to more typical late-winter atmospheric patterns after an unusually warm spell.
