The Bay of Cadiz enjoys the same temperate climate regime, typical of Mediterranean regions. Springtime in the area is characterised by mild temperatures, many hours of sunshine and quite irregular rainfall, less frequent in the months closest to summer.
The following tables summarise the climate of the Bay of Cadiz with the average and extreme values of temperature and rainfall recorded in Cadiz between 1981 and 2010, according to the National Climate Database of the Spanish Meteorological State Agency (AEMET).
The dominant winds in the Bay of Cádiz come from the West, mainly driven by high Atlantic pressures and sometimes associated with Atlantic frontal systems, although westerlies also obey the circulation of breezes, which takes on greater importance in the warm months. It is important to note the usual frequency of easterlies in the area, caused by the beam of Mediterranean airflow through the Strait of Gibraltar that eventually reaches the Bay with gusty winds from the ESE to SE of moderate intensity (10 to 20 kt). This wind regime is popularly called ‘levante’, which normally persist in the area for several days. The speeds of these easterly winds are higher than those coming from the west.
