*2.1. Location and Climate*

The city of Seville, in the south of Spain, has a typical Mediterranean climate with mild winters between December and March, very hot summers between June and September and short periods of variable temperatures between seasons in April–May and October–November, although each time with higher temperatures. Relative average humidity ranges from 44% to 80%, with variations inversely proportional to the daytime temperature due to air heating. The predominant wind direction is southwest with low speeds. There is a differentiation between the prevailing winds in winter, coming from the northeast, and those in summer, coming from the southwest. Seville also presents a large number of sunny days, with little cloudy or clear skies [45].
