Gibraltar is in the northern hemisphere so summer falls during June, July and August. Winter falls in December, January and February but it hardly gets cold enough for anyone to complain about.

Rainfall in the summer is almost nonexistent and you can expect 11 hours of sunshine every day during July. Humidity during this time of the year can be high, but it is dependent on wind direction.
In the cooler months of the year expect to see average max temperatures of around 16°C and higher rainfall. Even so, the winter months are still very popular with the tourists and the atmosphere is very welcoming.
Viento de Levante
Otherwise known as “The Levanter”, this is a Gibraltar weather occurrence which can be quite spectacular to witness. The easterly wind brings on this condition at random times throughout the year, but it occurs more frequently in the summer months.
The easterly wind blows towards Gibraltar from the warm Mediterranean Sea, bringing in lots of moisture with it. As the air hits the east facing side of the Rock or Gibraltar the moisture condenses and forms a large visible cloud over The Rock.
When The Levanter comes the rise in humidity is noticeable and the locals tend to stick with less strenuous activities during this time.
