The month of July is an excellent choice for those seeking for beach and sun. Actually in Malaga the temperatures are high and tourists use to choose a cold bath into the sea.
The month of July bring us some interesting options also like the Carihuela fair, where I saw some visitors from USA, many dutch people and young french and UK people coming with their schools for holidays.
The night in Malaga during the month of July is comfortable, July nights are perfect in Malaga for spending some time walking along the promenade or the beaches. If you like also visiting some nightclubs in Malaga, July and August are the favourite tourists months and where more people meet during the nightlife.
If you are taking your holidays during the month of July, Malaga is a recommended visit during your holidays.
