The historic university city of Salamanca is located in the western part of Castile, close to Extremadura. It shares the region's typical climate, where summer months can be extremely hot, while in winter the temperature can occasionally dip below freezing. Travelers planning a summer visit can expect to experience some daytime temperatures in the 90s during July and August, which can make exploring the historic center on foot a little uncomfortable. For this reason, the late spring or the fall are the best times to visit Salamanca, when temperatures hover in the 80s - certainly warm enough to sit outside at a bar or cafe and enjoy some early evening people watching. For travelers who love a traditional Spanish fiesta, the key dates in Salamanca are the second week in September when the city celebrates the Virgen de la Vega festival. This begins with a religious procession and continues with a week of concerts, food fairs, wine tastings, street markets, fairgrounds and fireworks displays across the city, with the spacious Plaza Mayor at the heart of the action. After the fiesta, the city's nightlife gets much livelier from mid September onwards, when the students return and the population swells.
