Merida, capital of the Extremadura region in western Spain, is home to the most complete collection of Roman ruins on the Iberian Peninsula. Founded in 25 BC as Emerita Augusta for retired Roman legionaries, the city became the capital of the province of Lusitania and one of the most important cities in the Roman Empire. Today its UNESCO World Heritage Site encompasses a theatre, amphitheatre, circus, temples, bridges, and aqueducts spread across a compact, walkable centre of about 60,000 people. Merida sits at 217 metres elevation in the Guadiana River valley, where a Mediterranean climate with strong continental influences brings long, scorching summers (July averages 35°C/95°F) and cool winters with occasional frost. Annual rainfall is just 450mm, making it one of Spain’s drier inland cities.

Where Is Merida and What Influences Its Weather
Merida sits in the Guadiana River valley in the autonomous community of Extremadura, about 340km southwest of Madrid and 200km north of Seville. The city lies at 38°55’N latitude and 6°20’W longitude at an elevation of 217 metres. Its inland position, roughly 300km from both the Atlantic coast of Portugal and the Mediterranean, gives it a continental climate influence: larger temperature swings between day and night and between summer and winter than you would find in coastal Spanish cities at the same latitude. The Sierra de San Pedro and Sierra de Montanchez ranges to the north provide minor rain-shadow effects but do not significantly alter the overall dry Mediterranean pattern. The surrounding landscape is dehesa: open oak woodlands and grasslands typical of Extremadura, which heat up rapidly in summer and contribute to the high daytime temperatures.
