Gibraltar's climate is mediterranean-temperate. During winter months lowest temperatures are of around 13ºC and highs that could reach 18ºC. Only about 30 percent of winter days are classified as wet.

In summer, the mainly dry season, the wind from the East or Levanter, brings warm and humid conditions and can generate a rather persistent 'Rock Top' cloud that hangs over the city area. Sea fog is not uncommon on these occasions. Summer brings an average of 10.5 hours of sunshine per day. The summer drought frequently lasts 90 consecutive days.
