Gijón is the largest city and municipality in the autonomous community of Asturias in Spain. Early medieval texts mention it as "Gigia". It is located on the Bay of Biscay, approximately 12 miles (19.31 kilometers) north of Oviedo, the capital of Asturias.
The city is situated on the coast of central Asturias, from sea level to an altitude of 513 meters at Picu Samartín and 672 meters at Peña de los Cuatro Jueces, bordered on the West by Carreño, the East by Villaviciosa, and to the South by Siero and Llanera
The city is situated along the Asturian coast and is distinguished by the peninsula of Cimavilla (the original settlement) which separates the beach of San Lorenzo and adjacent neighbourhoods to the east from the beaches of Poniente and Arbeyal, the shipyards, and the recreational port and the Port of El Musel to the west. It is close to the other main Asturian cities, Oviedo and Avilés.
Gijón has a temperate oceanic climate typical of the Atlantic coast of Spain, with cool summers and wet and mostly mild winters. The onshore flow from the Atlantic Ocean creates a cool summer and mild winter climate where severe heat and very cold temperatures are rare. The narrow temperature range is demonstrated by the record August temperature being only 6.4 °C warmer than the all-time record January temperature. The climate is wet and cloudy by Spanish standards, but is indeed drier than other locations on the Atlantic in the country. Humidity is high year-round.
Summer temperatures are very consistent as proven by the fact that the all-time warmest month of August 1997 had an average temperature of 20.9 °C (69.6 °F) and no month has ever been recorded at an average high above 24.7 °C (76.5 °F) in comparison to the 23.2 °C (73.8 °F) August normal high. Another clear underlining of the marine influence is that the coolest ever August has been as near the average as 17.9 °C (64.2 °F).
