Effects

The sirocco causes dusty dry conditions along the northern coast of Africa, storms in the Mediterranean Sea, and warm wet weather in Southern Europe. The sirocco does not affect other parts of Europe. The sirocco's duration may be as short as half a day or may last several days. While passing over the Mediterranean Sea, the sirocco picks up moisture; this results in rainfall in the southern part of

, known locally as "blood rain" due to the red sand mixed with the falling rain. Sirocco is commonly perceived as causing unease and an irritable mood in people. In addition, many people attribute health problems to the wind, either because of the heat and dust brought from African coastal regions, or because of the cool dampness further north in Europe. The dust in the sirocco winds can cause abrasion in mechanical devices and penetrate buildings. Sirocco winds with speeds of up to are most common during autumn and spring. They reach a peak in March and in November when it is very hot. When combined with a rising tide, the sirocco can cause the ''
