The climate of Gibraltar is Mediterranean/Subtropical with mild winters and warm summers. There are two main prevailing winds, an easterly one known as the Levante coming from the Sahara in Africa which brings humid weather and warmer sea currents and the other as Poniente which is westerly and brings fresher air and colder sea. Its terrain consists of the high Rock of Gibraltar and the narrow coastal lowland surrounding it. Rain occurs mainly in winter, the summers are generally dry.
