The yearly oxygen flow, nearly non-stop across the sea and over land, offers a complex mixture of fresh and invigorating air. Gibraltar's position at the gateway between the Atlantic Ocean and the Mediterranean Sea often leads to an interesting array of weather conditions.Temperatures climb steadily from a mild winter average of around 10°C (50°F) to reach a hot summer high of 29°C (84.2°F), demonstrating a considerable spread in temperatures throughout the year. Daylight hours extend from 9.7 to a pleasing 14.6 hours, amplifying the warmth during summer months. Sea temperatures also vary notably from a refreshing 15.8°C (60.4°F) in early spring to a peak of 23.3°C (73.9°F) in summer.
