The climate of Granada (southern Spain) during the first third of the 18th century is reconstructed. Results suggest that climatic conditions were similar to those of the first decades of the 20th century, when the global warming signal was of less importance than today. In addition, the paper presents the instrumental data taken in Granada in 1729, probably the first instrumental meteorological data recorded in Spain. Some extreme events, such as the cold wave of winter 1729, are studied.
